509Milepost IdentificationUsed to identify the milepost as detected by a milepost sensor. The length of the ASCII text for this parameter must be reported using SPN 3070 (Number of bytes in the Milepost Identification).
512Driver's Demand Engine - Percent TorqueThe requested torque output of the engine by the driver. It is based on input from the following requestors external to the powertrain: operator (via the accelerator pedal), cruise control and/or road speed limit governor. Dynamic commands from internal powertrain functions such as smoke control, low- and high-speed engine governing; ASR and shift control are excluded from this calculation. The data is transmitted in indicated torque as a percent of the reference engine torque. See PGN 65251 for the engine configuration message. Several status bits are defined separately to indicate the request which is currently being honored. This parameter may be used for shift scheduling.
513Actual Engine - Percent TorqueThe calculated output torque of the engine. The data is transmitted in indicated torque as a percent of reference engine torque (see the engine configuration message, PGN 65251). The engine percent torque value will not be less than zero and it includes the torque developed in the cylinders required to overcome friction.
514Nominal Friction - Percent TorqueThe calculated torque that indicates the amount of torque required by the basic engine itself added by the loss torque of accessories. It contains the frictional and thermodynamic loss of the engine itself, pumping torque loss (SPN 5398), and the losses of fuel, oil and cooling pumps. The data is transmitted in indicated torque as a percent of reference engine torque (see the engine configuration message, PGN 65251).

The realization can be done by a map dependent on engine speed and engine temperature and an offset value for additional loss torques.

See SPN 2978 for an indicator that describes the possible inclusion of engine parasitic losses such as cooling fan, etc. in this parameter value.

Note: Refer to section 5.2.1.
515Engine's Desired Operating SpeedAn indication by the engine of the optimal operating speed of the engine for the current existing conditions. These conditions may include the torque generated to accommodate powertrain demands from the operator (via the accelerator pedal), cruise control, road speed limit governors, or ASR. Dynamic commands from functions such as smoke control or shift control are excluded from this calculation.
516Ground-Based Vehicle SpeedActual ground speed of the vehicle, measured by a device such as RADAR. (1.609344 km/h = 1 mph)
517Navigation-Based Vehicle SpeedSpeed of the vehicle as calculated from a device such as a Global Positioning System (GPS).
518Engine Requested Torque/Torque LimitParameter provided to the engine or retarder in the torque/speed control message for controlling or limiting the output torque.

Requested torque to the engine is measured in indicated torque as a percentage of reference engine torque (see the engine configuration message, PGN 65251). This is the engine torque at which the engine is expected to operate if the torque control mode is active or the engine torque which the engine is not expected to exceed if the torque limit mode is active.

Zero torque can be requested which implies zero fuel and, according to Figures SPN512_A and SPN512_B, the engine will not be allowed to stall. The actual engine percent torque (SPN 513) should be zero and the engine should decelerate until the low idle governor kicks in, at which time the actual engine percent torque will be calculated as shown in Figures SPN512_A and SPN512_B and the engine torque mode bits (SPN 899) should be equal to 0000b - Low Idle Governor.

Requested torque to the retarder is measured in indicated torque as a percentage of reference retarder torque (see the retarder configuration message, PGN 65249). The logic used in enabling or disabling the retarder is based on the override control mode priority bits (SPN 897).

A zero torque request to the retarder is a disable request, and is used by a J1939 node to prevent the retarder from being activated by other combinations of inputs outside of J1939 commands. The Torque Limit Mode is commonly used for this purpose.
519Engine's Desired Operating Speed Asymmetry AdjustmentThis byte is utilized in transmission gear selection routines and indicates the engine's preference of lower versus higher engine speeds should its desired speed not be achievable. This is a scaled ratio such that 125 represents an equal preference for a speed lower or higher that the engine's indicated desired speed. The higher the asymmetry adjustment value is above 125, the more the engine prefers to be operated at or above its indicated desired speed. Conversely, the lower the asymmetry adjustment value is below 125, the more the engine prefers to operate at or below its indicated desired speed. Typically, the engine's asymmetry adjustment will be predicated on fuel consumption considerations, and under these conditions, the method for computing the asymmetry adjustment is indicated in Figure SPN519_A. The engine may include other factors into its asymmetry adjustment calculation such as temperatures, pressures, and other operating parameters.
520Actual Retarder - Percent TorqueActual braking torque of the retarder as a percent of retarder configuration reference torque SPN 556.

Note: Refer to section 5.2.1.
521Brake Pedal PositionRatio of brake pedal position to maximum pedal position. Used for electric brake applications. 0% means no braking. Also when there are two brake pedals on the machine (Left Brake Pedal Position SPN 3033 and Right Brake Pedal Position SPN 3032) the maximum of the two should be transmitted for Brake Pedal Position.
522Percent Clutch SlipParameter which represents the ratio of input shaft speed to current engine speed (in percent).

Percent Clutch Slip = ((Engine rpm - Input shaft rpm)/(Engine rpm)) x 100
523Transmission Current GearThe gear currently engaged in the transmission or the last gear engaged while the transmission is in the process of shifting to the new or selected gear. Transitions toward a destination gear will not be indicated. Once the selected gear has been engaged then Transmission Current Gear (SPN 523) will reflect that gear.
524Transmission Selected GearThe gear that the transmission will attempt to achieve during the current shift if a shift is in progress, or the next shift if one is pending (i.e., waiting for torque reduction to initiate the shift).
525Transmission Requested GearGear requested by the operator, ABS, or engine.

0xF3 (243 dec) = D-3: 3rd forward selector position referenced from ‘Drive’
0xF2 (242 dec) = D-4: 4th forward selector position referenced from ‘Drive’
0xF1 (241 dec) = D-5: 5th forward selector position referenced from ‘Drive’
0xF0 (240 dec) = D-6: 6th forward selector position referenced from ‘Drive’
0xEF (239 dec) = D-7: 7th forward selector position referenced from ‘Drive’
0xEE (238 dec) = Between two shift selector positions (if detail is unknown)
0xED (237 dec) = Between two reverse shift selector positions
0xEC (236 dec) = Between two forward shift selector positions
0xEB (235 dec) = Between D-7 and D-6 shift selector positions
0xEA (234 dec) = Between D-6 and D-5 shift selector positions
0xE9 (233 dec) = Between D-5 and D-4 shift selector positions
0xE8 (232 dec) = Between D-4 and D-3 shift selector positions
0xE7 (231 dec) = Between D-3 and D-2 shift selector positions
0xE6 (230 dec) = Between D-2 and D-1 shift selector positions
0xE5 (229 dec) = Between D-1 and ‘Drive’ shift selector positions
0xE4 (228 dec) = Between ‘Drive’ and ‘Neutral’ shift selector positions
0xE3 (227 dec) = Between ‘Neutral’ and ‘Reverse’ shift selector positions
0xE2 (226 dec) = Between ‘Reverse’ and ‘Park’ shift selector positions
0xE1 (225 dec) = Press of momentary button to reselect current position
0xE0 (224 dec) = Position unknown and/or no buttons pressed
0xDF (223 dec) = Reverse Selector Position

0xDE - 0xBE (222 dec - 190 dec) = Reserved
0x3C - 0x00 (60 dec - 0 dec) = Reserved

Forward selector position from drive (0xF5 to 0xEF) – Indicates shift selector position in reference to the ‘Drive’ position on the selector. It is possible that the shift selector software may not know the number of forward ranges. The shift selector may identify the position selected by the operator while the transmission ECU determines what range or gear that represents. If there is a digital display, the transmission ECU would communicate what is to be displayed via another message such as ETC#2 or ETC#7.

For example: Consider a vehicle with a 5-speed automatic transmission with the shift lever on the column. Suppose that shift selector has a limited number of positions, such that having positions for D-4-3-2-1 is not an option. For this example, assume there are only have enough lever positions for D-3-2-1. Pulling the lever into "D" will put the transmission in 5th (highest gear). It is desired that pulling the lever to the physical “3” position will limit the transmission to a maximum range of 3rd gear.

When the selector is pulled down into "3", the shifter selector itself has no way of correlating this physical lever position to the desired gear; it would have to be calibrated with software to tell it this information. If not calibrated, the shift selector cannot directly command the transmission to go to 3rd gear; it only knows it's one notch below drive.

However, if "D-1" (lever position, as opposed to desired gear) is broadcast by the selector, the transmission ECU can receive this and then make the determination of what range is desired. The benefit is that no specific calibration of the shift selector is required.

Between selector positions (0xEE to 0xE2) – Indicates the shift selector is not in an appropriate position. If a lever-type shift selector with a mechanical display is stuck between detents, it may appear to the operator that it is in the desired position when in fact it is not. The shift selector may be capable of reporting only that it is between positions or that it is between forward or reverse positions. If known, the transmission ECU may respond differently depending on which positions are involved.

Reselect current position (0xE1) - If the TC1 message continues to send the position last selected, then a capability to reselect the same position is required. For example: If a ‘Neutral to Drive’ shift is selected and that shift is inhibited (say for high engine speed), it may be necessary for the operator to reselect ‘Drive’ after the inhibit conditions pass in order for the transmission ECU to honor the request.

Position unknown and/or no buttons pressed (0xE0) - A push-button style shift selector with momentary contact buttons may send this indicator after initialization before any buttons are pressed, or before the transmission ECU determines and communicates the initial selection. This indicator could also be sent between button presses as an alternative to sending the last button press.

571Retarder Enable - Brake Assist Switchhe retarder to be enabled for vehicle braking assist. The retarder does not check this switch, nor does the enabling of this switch engage the retarder. When this switch is “enabled,” the devices constructing TSC1 – destination retarder messages may command retarder torque for braking. For example, the cruise control should not request retarder torque if this switch is not “enabled.” The switch exists to prevent the engine retarder from being asked to be engaged via TSC1 in a noise sensitive area.

574Transmission Shift In ProcessIndicates that the transmission is in process of shifting from the current gear to the selected gear. This state is generally ACTIVE during the entire time that the transmission controls the vehicle during a shift. This includes any transmission clutch control, all engine control sequences, pulling to transmission neutral, and engaging the destination gear (e.g., until it is no longer sending commands and/or limits to the engine). See also SPN 560. (See Figure SPN574_A)

695Engine Override Control ModeThe override control mode defines which sort of command is used:

00 Override disabled - Disable any existing control commanded by the source of this command.
01 Speed control - Govern speed to the included “desired speed” value.
10 Torque control - Control torque to the included “desired torque” value.
11 Speed/torque limit control - Limit speed and/or torque based on the included limit values. The speed limit governor is a droop governor where the speed limit value defines the speed at the maximum torque available during this operation.

If a device wants to know whether it has access to the engine, there are several possibilities:

a. Comparing its command with the actual engine broadcasts.
b. Looking at command modes from other devices.
c. Looking to the engine and retarder torque mode.

Remarks:

a. The realization of a torque limit (minimum selection) is possible by setting the speed limit to a high value (0xFAFF).
b. The realization of a speed limit (minimum selection) is possible by setting the torque limit to a high value (0xFA).
c. Limiting the retarder torque means to limit the magnitude of the torque request. As the brake torque is represented by negative torque values, the limitation must be done by a maximum selection of the requested torque and the retarder internal torque signals.
d. For torque increasing functions, time limits for the torque or speed value (command) and the direct modes are desirable.

e. The selection of which device has control of the engine's speed or torque depends on the override mode priority (see SPN 897) with the highest priority device gaining control. In the case of two devices with identical priority, the engine responds to speed/torque control commands over speed/torque limit commands and will act on the speed or torque commands on a first come, first served basis. The torque limit will be a “lowest wins” selection (e.g., if one device commands 60% limit and another 80% limit, then the engine will limit torque to 60%). Figure SPN695_A provides a flowchart of the torque/speed control priority selection logic.
696Engine Requested Speed Control ConditionsThis mode tells the engine control system the governor characteristics that are desired during speed control. The four characteristics defined are:

00 Transient Optimized for driveline disengaged and non-lockup conditions
01 Stability Optimized for driveline disengaged and non-lockup conditions
10 Stability Optimized for driveline engaged and/or in lockup condition 1 (e.g., vehicle driveline)
11 Stability Optimized for driveline engaged and/or in lockup condition 2 (e.g., PTO driveline)

00b - This speed governor gain selection is adjusted to provide rapid transition between speed setpoints. RPM overshoot and undershoot may be greater than what is seen when the “speed control characteristic” is set to be stability optimized.

01b - This control condition has been optimized to minimize rpm overshoot and undershoot given an expected plant consisting of the engine and its accessory loads. This gain adjustment is not intended to compensate for driveline characteristics. This characteristic is most appropriate when no driveline is connected.

10b - This control condition has been optimized to minimize rpm overshoot and undershoot given a more complex plant. For instance, the more complex plant would contain the engine, its accessory loads and the driveline characteristics. As an example, the driveline characteristics might include the effective spring mass relationship of pumps, tires, clutches, axles, driveshafts, and multiple gear ratios. This characteristic is most appropriate when a driveline is engaged.

11b - This speed control characteristic is available for applications requiring compensation for more than one driveline characteristic. It has been optimized to minimize rpm overshoot and undershoot given a more complex plant of the second variety. This more complex plant would again contain the engine, its accessory loads and a second driveline characteristic unique from the one described in speed control characteristic 10b.

897Override Control Mode PriorityThis field is used as an input to the engine or retarder to determine the priority of the Override Control Mode received in the Torque/Speed Control message (see PGN 0). The default is 11 (Low priority). It is not required to use the same priority during the entire override function. For example, the transmission can use priority 01 (High priority) during a shift, but can set the priority to 11 (Low priority) at the end of the shift to allow traction control to also interact with the torque limit of the engine.

The four priority levels defined are:

00 Highest priority
01 High priority
10 Medium priority
11 Low priority

00b - Highest Priority = Used for situations that require immediate action by the receiving device in order to provide safe vehicle operation (i.e., braking systems). This level of priority should only be used in safety critical conditions.

01b - High Priority = Used for control situations that require prompt action in order to provide safe vehicle operation. An example is when the transmission is performing a shift and requires control of the engine in order to control driveline reengagement.

10b - Medium Priority = Used for powertrain control operations which are related to assuring that the vehicle is in a stable operating condition. An example is when the traction control system is commanding the engine in order to achieve traction stability.

11b - Low Priority = Used to indicate that the associated command desires powertrain control but is needed for function which improves the driver comfort which may be overridden by other devices. An example is cruise control or the non-critical part of a transmission shift to a new gear.
898Engine Requested Speed/Speed LimitParameter provided to the engine from external sources in the torque/speed control message. This is the engine speed which the engine is expected to operate at if the speed control mode is active or the engine speed which the engine is not expected to exceed if the speed limit mode is active.
899Engine Torque ModeState signal which indicates which engine torque mode is currently generating, limiting, or controlling the torque. Note that the modes are not in prioritized order. Not all modes may be relevant for a given device. Some devices may not implement all functions. For typical priorities refer to Figures SPN512_A and SPN512_B for engine control. The data type of this parameter is measured.

Mode 0000b means “No request”: engine torque may range from 0 to full load only due to low idle governor output.

Modes 0001b to 1110b indicate that there is either a torque request or the identified function is currently controlling the engine: engine torque may range from 0 (no fueling) to the upper limit.
900Retarder Torque ModeState signal which indicates which retarder torque mode is currently generating, limiting, or controlling the torque. Note that the modes are not in prioritized order. Not all modes may be relevant for a given device. Some devices may not implement all functions. For typical priorities refer to Tables SPN518_A to SPN518_B for retarder control. The data type of this parameter is measured.

Mode 0000b means “No request”: retarder torque = 0 (no braking).

Modes 0001b to 1110b indicate that there is either a torque request or the identified function is currently controlling the retarder: retarder torque may range from 0 (no braking) to the upper limit.
901Retarder TypeA vehicle retarder is a supplementary device to the wheel brakes for the driver to better control the vehicle. The wheel brakes used in the vehicle are not designed for continuous retarding operation. In a prolonged period of braking, the brakes can be thermally over-stressed, causing the braking effect to be reduced or even lead to complete braking system failure. The vehicle retarder is designed for continuous operation for braking during downhill operation and is also used for braking the vehicle to comply with speed limits and traffic conditions.

This parameter provides some indication of the retarder dynamics. It is used in the retarder configuration message. The data type of this parameter is measured.

1214Suspect Parameter NumberThis 19-bit number is used to identify the item for which diagnostics are being reported. The SPN is used for multiple purposes, some of those that are specific to diagnostics are:

1. to identify a least repairable subsystem that has failed;
2. to identify subsystems and or assemblies that may not have hard failures but may be exhibiting abnormal operating performance;
3. identifying a particular event or condition that will be reported;
4. to report a component and non-standard failure mode.

SPNs are assigned to each individual parameter in a Parameter Group and to items that are relevant to diagnostics but are not a parameter in a Parameter Group. SPNs are independent of the source address for the message. However, the source address may be necessary to determine which controller on the network performed the diagnosis.

1216Occurrence CountThe 7-bit occurrence count field contains the number of times a fault has been independently detected. The occurrence count is reported as 1 the first time the DTC is detected. The occurrence count is not incremented again, until after the DTC has gone to the previously active state and then back active the DTC state when subsequently detected. At this point the occurrence count would be reported as 2. This continues until the DTC has been independently detected 126 times. The occurrence count shall not be incremented from 126 to 127 -- it shall remain at 126 until cleared by DM3 or DM11.

If an occurrence count is not available, then this field should be set to all binary ones (127). The occurrence count is not incremented just do to an ignition key-off and ignition key-on. The diagnostic system shall have monitored the system or component (e.g. DTC) to see that it is no longer malfunctioning in order to declare it previously active.

1545SPN DataThe SPN data field represents the data pertaining to one or more SPNs that were reported in DM24. The order and number of bytes per SPN is determined from the DM24 response.

In DM25, an entire byte is used for each parameter if the parameter itself is less than 8 bits long. The SPN data value shall be placed into the byte right justified to the least significant bit, regardless of its defined position in the normal data PGN. Any remaining bits of the data byte shall be reported as '0'. For example, if SPN 559 (accelerator pedal kick-down switch) is reported as a DM25 freeze frame parameter, the SPN 559 data will reside in bits 1 and 2 of the byte in DM25, even though this parameter data reported in bits 3 and 4 of PGN 61443. The remaining unused bits of this byte in the DM25 message will be filled with '0'. Each of the remaining 6 most significant bits of this freeze frame byte (bit 2 to bit 8) will be filled with '0'

Values which are less than 128 decimal are bit-mapped values and any combination of these values is considered a valid value. For example communicating the "High Fine LED on" value to the display would result in the High Fine LED being turned on. Communicating a value with the "High Fine LED on" bit set to "1" and the "On-Grade LED on" bit set to "1" should result in the display turning on the High Fine LED AND the On-Grade LED.

Values 128 decimal and above are discrete states. Any bit-mapped combination of these states are invalid unless the results correspond to one of the states defined. For example, the result of adding the "Low Coarse" and "Low Medium" states results in the "Low Medium" state, which is valid. However, adding the "Low Medium" and the "Low Fine" states results in an value which does not have a defined state and is invalid.

1590Adaptive Cruise Control ModeThis parameter is used to indicate the current state, or mode, of operation by the Adaptive Cruise Control (ACC) device. The states characterize independent system states (e.g., it is not possible to express distance control active and overtake mode simultaneously). ACC must not switch itself off while active because the driver expects it to work. So if an error occurs, the ACC must signal that to the driver so that the driver knows that he has to switch off the ACC.

111 Not available/not valid

000b - Off—Used to indicate the ACC is enabled in calibration or configuration and there are no faults that would prevent the system from operating.
001b - Speed Control Active—Used to indicate that ACC is on but not currently sending control messages. In other words, there is no target ahead and regular vehicle cruise control is controlling the vehicle speed to the driver’s set speed.
010b - Distance Control Active—Used to indicate that ACC is on and actively sending control messages to maintain the appropriate following interval.
011b - Overtake Mode—Used to indicate that ACC is on but temporarily disabled because the driver is manually overriding cruise control by using either the accelerator pedal or the cruise control “accel” switch.
100b - Hold Mode—Used to indicate that the ACC has lost the previous target vehicle and is in HOLD mode. In this mode, the ACC shall limit the speed to the speed held when the target was lost. For example, if the driver activates the typical cruise buttons (Resume/Inc/Dec) the HOLD mode shall be exited and normal cruise functionality resumed. If a new target is detected, the Distance Control Active mode (010b) is again entered, unless existing conditions prohibit this.
101b - Finish Mode—Used to indicate that ACC is on with no target ahead, and ACC is currently sending control messages to return to the driver’s set speed. This occurs when the target the ACC system was tracking moves out of the way so ACC returns the vehicle to the driver’s set speed.
110b - Disabled or Error Condition—Used to indicate that ACC is in an error state and can not operate.
1591Road curvatureEstimated value of the current road curvature for use by the adaptive cruise control system. Positive values are used for left curves. Curvature is the inverse of the radius and is zero for straight roads.

1598Fan 2 SpeedThe speed of the second fan associated with engine coolant system.
1599SeedThis is a 16-bit parameter which is used by the Device primarily to send a Seed to a Tool, when using a Seed/Key type security system. It is also used by the Device to signal the Tool that the Device is satisfied that a complete Key has been received or that the Data Security message is expected to contain the Seed data. This parameter can also contain an expected time to completion when the EDCP Extension is 7. The Seed is to be the mathematical basis upon which any Key is calculated. The Device verifies the validity of the Key {Seed} from the Tool and enable memory access operations appropriately.
1600High Resolution Engine Fuel RateAmount of fuel consumed by engine per unit of time.

1601Local minute offsetThe minute component of the offset between the UTC time and date and a local time zone time and date. This is the number of minutes to add to UTC (Universal Time Coordinate) time and date to convert to the time and date in the local time zone . The Local Offset is a positive value for time zones East of the Prime Meridian to the International Date Line. The Local Offset is a negative value for time zones West of the Prime Meridian to the International Date Line.
The Local Minute Offset is only applicable when the Time and Date parameters are reported as UTC time and date. Refer to SPN 1602 for details.
1602Local hour offsetThe hour component of the offset between the UTC (Universal Time Coordinate) time and date and a local time zone time and date. This is the number of hours to add to UTC, a.k.a. GMT, time and date to convert to the time and date in the local time zone. This parameter indicates the time reference of the data reported in the Time and Date SPNs 959, 960. 961, 962, 963, and 964. The Local Offset is a positive value for time zones East of the Prime Meridian to the International Date Line. The Local Offset is a negative value for time zones West of the Prime Meridian to the International Date Line.
The Local Hour Offset is only applicable when the Time and Date parameters are reported as UTC time and date.

Recommended Settings:

Applications should not use the $FF 'Not Available' if using the Time and Date parameters due to some ambiguity of the time standard for the reported time and date values. The recommended settings for the Local Hour Offset settings are:
If reporting the Time and Date as Local time, then Local Hour Offset must be reported as $FA.
If reporting the Time and Date as UTC time and Local Hour Offset is not supported or not known, then Local Hour Offset must be reported as $F9.
If reporting the Time and Date as UTC time and Local Hour Offset is known, then Local Hour Offset must be reported as a value between $66 and $94.

1640Length/Number RequestedThis is an 11-bit parameter which identifies the amount of memory (i.e. the range within the memory) over which the Tool desires an operation to be carried out when the Command of the Memory Access Request message is a Read, Write, Boot Load, or Error Detection and/or Correction Parameter (EDCP) Generation.
1641Pointer TypeIndicates whether the Pointer and Pointer Extension are direct memory addresses (Pointer Type identifier = 0) or if the Pointer Extension is identifying a particular SPACE with the Pointer referencing a specific OBJECT within that particular SPACE (Pointer Type identifier = 1).

0 Direct Memory Addressing
1 Direct Spatial Addressing
1642CommandThis is a 3-bit parameter which allows the Tool to send Commands to the Device. All Memory Access Requests originate at a Tool and are considered Commands. Some of the values within the Command have been overlaid with the same values in Status so perhaps a similar variable can be used.
1643Pointer ExtensionThis parameter is either the high order 8 bits of a complete direct memory address or the identifier of a particular spacial address.
1644Pointer If Pointer Type 0 is used, this 24-bit parameter, which has a value of 0 to 16,777,215 (0 to 0xFFFFFF) with no reserved ranges, is concatenated with the 8-bit Pointer Extension to form a direct memory address. The address thus formed represents the first address to be accessed within the memory in units of bytes. If Pointer Type 1 is used, the Pointer is to provide the identification of the specific OBJECT within whatever particular SPACE is being identified by the Pointer Extension. The direct memory address should be parsed as outlined below if the device memory width is other than 1 byte.
1645Key/User_LevelThis is a 2-byte parameter which is used by the Tool to primarily send a Key to the Device, but which can also be used by the Tool to provide a Password or a User_Level to the Device if desired (see APPENDIX C). This Key/User_Level parameter can be used to send these independent variables since they will never be transmitted within the same message (a Password or User_Level parameter would be sent at the beginning of an operation, while a Key CANNOT be sent until after the receipt of a Seed).
1646Status (for DM 15)This is a 3-bit parameter which allows the Device to return its Status. All Memory Access Requests originate at a Tool and are considered Commands. All Memory Access Responses originate at a Device and are considered Status. The device may choose to send further information on its status within the Error Indicator/EDC Parameter
1647EDCP ExtensionThis is an 8-bit parameter used to identify how to handle the data in the Error Indicator/ EDC Parameter. This EDCP Extension parameter is used within the Memory Access Response message (Device to Tool). Meaning must be determined from a table of predefined values. If there is no Error Indicator/EDC Parameter being sent then this (EDCP Extension) parameter must be properly set (0b11111111).
1648Error Indicator/EDC ParameterThis is a 24-bit parameter which has two uses. One is to transfer a checksum, CRC or other type of EDC parameter (or any segment thereof) from a device to a Tool within the Memory Access Response message. The second use is to send an Error Indicator any time the Device is not able to complete or act upon a Tool’s request.
1649Length/Number Allowed-bit parameter identifies the amount of memory (i.e. the range of memory) over which the Device is willing to allow a particular operation to be carried out. For ‘Proceed’ the length value is either in bytes or objects. When the Status of the Memory Access Request is Busy, Operation Failed, or Operation Completed the length is meaningless. The Device should therefore send it as '0' and the Tool should treat it as ‘DO NOT CARE’.
1650Number of Occurrences of Raw Binary DataThis is an 8-bit (1-byte) parameter to be sent within the Binary Data Transfer PGN to provide information on the number of Raw Binary Data parameters which will follow when the message is single packet. Its value is between 1 and 7 when the Binary Data Transfer PGN is not multipacketed.
1651Raw Binary DataThis is a 1-byte parameter representing the value for 1 byte of memory. It can have any value between 0 and 255 (0 and 0xFF) with no reserved values.
1651Raw Binary DataThis is a 1-byte parameter representing the value for 1 byte of memory. It can have any value between 0 and 255 (0 and 0xFF) with no reserved values.
1652Boot Load DataThis is a 1-byte parameter using the same SLOT as the Raw Binary Data. There shall be 8 occurrences of this parameter in the message. The meaning of this parameter is proprietary. The structure used to reference the program and verify the data is also proprietary.

1706SPN Conversion MethodWhen this 1-bit field is equal to a zero, the SPN should be converted as it is defined. The February 1996 version of J1939-73 contained inadequate definitions to assure consistent implementations. Products implementing to February 1996 version of the document will always have this bit set to a one. When this is the case, the SPN is in either Version 1, 2 or 3 format. The original publication of this recommended practice defined that this bit be set to one. This particular implementation is no longer permitted. It provides context for some implementations prior to the adoption of the recommended setting as zero (version 4 definition).

To clarify the ordering of bits and bytes within the SPN parameter (which is 19 bits long) and to keep that ordering consistent with other parameters in J1939-71 and J1939-73, the bit order has been respecified. See Version 4 below for the recommended formatting. Version 4 is required for any device complying with emissions related components.

To reduce problems in interpretation of the SPNs the bit between the FMI field and the Occurrence Count field, previously reserved, will be cleared to zero to identify use of the currently specified SPN bit pattern. This bit now comprises an SPN Conversion Method for the purpose of maintaining usability of those implementations that are already in use.


0 means convert SPNs per the Version 4 definition below
1 means convert SPNs per Version 1, 2 or 3 specified below.

The four versions of interpretation are:
1. SPN assumed to be sent most significant bit first
2. SPN represented as Intel format for most significant 16 bits with 3 least significant bits of 19 bits in with FMI value.
3. SPN represented as Intel format for all 19 bits (least significant sent first)
4. SPN represented as Intel format for all 19 bits with the SPN Conversion Method set to 0.

1706SPN Conversion MethodWhen this 1-bit field is equal to a zero, the SPN should be converted as it is defined. The February 1996 version of J1939-73 contained inadequate definitions to assure consistent implementations. Products implementing to February 1996 version of the document will always have this bit set to a one. When this is the case, the SPN is in either Version 1, 2 or 3 format. The original publication of this recommended practice defined that this bit be set to one. This particular implementation is no longer permitted. It provides context for some implementations prior to the adoption of the recommended setting as zero (version 4 definition).

To clarify the ordering of bits and bytes within the SPN parameter (which is 19 bits long) and to keep that ordering consistent with other parameters in J1939-71 and J1939-73, the bit order has been respecified. See Version 4 below for the recommended formatting. Version 4 is required for any device complying with emissions related components.

To reduce problems in interpretation of the SPNs the bit between the FMI field and the Occurrence Count field, previously reserved, will be cleared to zero to identify use of the currently specified SPN bit pattern. This bit now comprises an SPN Conversion Method for the purpose of maintaining usability of those implementations that are already in use.

To reduce problems in interpretation of the SPNs the bit between the FMI field and the Occurrence Count field, previously reserved, will be cleared to zero to identify use of the currently specified SPN bit pattern. This bit now comprises an SPN Conversion Method for the purpose of maintaining usability of those implementations that are already in use.


0 means convert SPNs per the Version 4 definition below
1 means convert SPNs per Version 1, 2 or 3 specified below.

The four versions of interpretation are:
1. SPN assumed to be sent most significant bit first
2. SPN represented as Intel format for most significant 16 bits with 3 least significant bits of 19 bits in with FMI value.
3. SPN represented as Intel format for all 19 bits (least significant sent first)
4. SPN represented as Intel format for all 19 bits with the SPN Conversion Method set to 0.
1706SPN Conversion MethodWhen this 1-bit field is equal to a zero, the SPN should be converted as it is defined. The February 1996 version of J1939-73 contained inadequate definitions to assure consistent implementations. Products implementing to February 1996 version of the document will always have this bit set to a one. When this is the case, the SPN is in either Version 1, 2 or 3 format. The original publication of this recommended practice defined that this bit be set to one. This particular implementation is no longer permitted. It provides context for some implementations prior to the adoption of the recommended setting as zero (version 4 definition).

1715Drivers Demand Retarder - Percent TorqueThe Drivers demand retarder – percent torque is the maximum torque selected by the driver when one or more modes are selected by the driver, such as hand lever, switch, constant torque, constant velocity, etc.
1716Retarder Selection, non-engineThe “Retarder Selection, non-engine” is the position of the driver’s selector for retarders that are not part of the engine system, expressed as percent and determined by the ratio of current position to the maximum possible position. The physical device may be a lever, rotary dial, combination of switches, or other device that the driver can use to select the type or amount of retardation needed.
1717Actual Maximum Available Retarder - Percent TorqueThis is the maximum amount of torque that the retarder can immediately deliver. It is the same as the maximum torque shown in the Retarder’s Configuration message, but allows for a much faster rate of change than could be communicated by reissuing the configuration message.
Application Note: The purpose for this parameter is to allow a “Master” retarder controller to more accurately allocate the vehicle’s retarder requirements among multiple retarders. Its value should be the same as the value in the Configuration message at the time that message is assembled for broadcast, but may vary between those broadcasts.

1734Nominal Level Front AxleSignal which indicates the nominal (desired) height of the front axle to be controlled by the suspension system.

These heights are discrete levels. They are the upper level, lower level, normal level 1, normal level 2, normal level 3, customer level, and preset level. Refer to Figure SPN1734_A.

? Upper Level is the highest mechanically available height of the vehicle.
? Lower Level is the lowest mechanically available height of the vehicle.

Normal Levels 1, 2 and 3 are heights normally used during driving.
? Normal Level 1 is most often used and is given by design.
? Normal Level 2 may be chosen, for example, to be lower than Normal Level 1 for the purpose of reducing fuel consumption while driving on highways.
? Normal Level 3 may be chosen above Normal Level 1 for driving off road.

The preset level has to be set by means of ASC 6 (PGN: 53504).

States 'Raising' and 'Lowering' are only active when corresponding states are requested in SPN 1751. This provides the possibility to adjust vehicle to a level other than the predefined levels.

1845Transmission Torque LimitParameter provided to the engine from the transmission as a torque limit to be invoked by the engine in the event that J1939 communication with the transmission is lost.

The intention is to protect transmissions that use a continuous torque limit during torque converter mode or operation in specific lower gears, where stall or drivetrain torque may reach levels higher than the gearbox capacity. If communication is lost during torque limited operation, unrestricted engine torque output could harm the transmission.

It is recommended that engines use reception of the ETC#1 message as a transmission “heartbeat”. In the event that the ETC#1 message is not received in a time period of 5 times its’ broadcast rate (5 x 10 ms = 50 ms), the engine should invoke a torque limit holding the engine to less than or equal to the value of the Transmission Torque Limit parameter. The engine may release the limit when transmission-to-engine communication is re-established.

A value of 0xFF00 to 0xFFFF indicates that no transmission torque limit is desired.

It is expected that the engine will record this torque value in non-volatile memory and will include this in the engine configuration PGN as parameter Engine Default Torque Limit (SPN 1846)

If the engine observes change in this parameter value on power-up, the engine should record the new value.
1846Engine Default Torque LimitCompanion parameter to Transmission Torque Limit (SPN 1845). This “echo” parameter provides confirmation to the transmission that the engine has received and will invoke the requested Transmission Torque Limit in the event that J1939 communication is lost between the two devices.

If the engine supports this protection logic, the Engine Default Torque Limit parameter should be set equal to the Transmission Torque Limit parameter as received in the Transmission Configuration 2 message (PGN 65099). Otherwise, an Engine Default Torque Limit value of FF00 to FFFF indicates that no engine default torque limit has been received or set.

The intention is to protect transmissions that use a continuous torque limit during torque converter mode or operation in specific lower gears, where stall or drivetrain torque may reach levels higher than the gearbox capacity. If communication is lost during torque limited operation, unrestricted engine torque output could harm the transmission.

It is recommended that engines use reception of the ETC#1 message as a transmission “heartbeat”. In the event that the ETC#1 message is not received in a time period of 5 times its’ broadcast rate (5 x 10 ms = 50 ms), the engine should invoke a torque limit holding the engine to less than or equal to the value of the Transmission Torque Limit parameter. The engine may release the limit when engine-to-transmission communication is re-established.
1849Transmission Requested Range Display Flash StateState signal indicating a transmission request for the display of the Transmission Requested Range parameter (SPN 162) to flash or not to flash. The ‘Transmission Requested Range Display Flash State’ indicator can be utilized by (but not limited to) the shift console, instrument cluster, or cab display. Definition of the cause of this state is at the discretion of the transmission manufacturer. The flash period shall be 700 ms @ 50% duty cycle.

Transmission manufacturers may want to flash the Transmission Requested Range display depending on certain events. It could be because a gear could not be attained, or because fluid is low, etc. Indicator should be on for 350 ms and off for 350 ms.

Transmissions supporting both this parameter and the Transmission Requested Range Display Blank

2540Parameter Group Number (RQST)Whenever it is necessary to identify a Parameter Group in the data field of a CAN data frame, it will be expressed in 24 bits. The Parameter Group Number is a 24 bit value that has the following constituent components: Reserved bit, Data Page bit, PDU Format Field (8 bits), and Group Extension Field (8 bits).

The procedure for the bit fields to be converted to Parameter Group Numbers is as follows. If the PF value is less than 240 (F016) then the lower byte of the PGN is set to the Zero. Note that not all 131, 071 combinations are available for assignment (calculated as: 2 pages * [240 + (16*256)] = 8,670) using the conventions specified in this document. See SAE J1939, Appendix A, to see the assignments to date. Reference the PGN table, Table 2, for an illustration of the bits and their corresponding conversion to a decimal number.
2541Control Byte (ACKM)Indicates the acknowledgement response.

Manufacturer codes are assigned by committee and may be found in the SAE J1939 base document. The Manufacturer Code field is not dependent on any other field in the NAME.
2839Function InstanceThe Function Instance is a 5-bit field that identifies the particular occurrence of a Function on the same Vehicle System on a given network.

Note that in the case of single or first Function of a particular type, the instance field should be set to zero indicating the first instance.

Individual manufacturers and integrators are advised that some agreement in the interpretation and use of Function Instances may be necessary. As an example, consider an implementation consisting of two engines and two transmissions. It may be important that engine instance 0 be physically connected to transmission instance 0 and that engine instance 1 be physically connected to transmission instance 1.
2840ECU InstanceThe ECU Instance is a 3-bit field that indicates which one of a group of electronic control modules associated with a given Function is being referenced. For example, in the case where a single engine is managed by two separate control units, each of which is attached to the same SAE J1939 network, the ECU Instance Field will be set to 0 for the first ECU and 1 for the second ECU.

Note that in the case of a single or first ECU for a particular CA, the instance field should be set to zero indicating the first instance.
2841FunctionFunction is an 8-bit field defined and assigned by the committee. When Function has a value of 0 to 127 (See Appendix B, Table B11), its definition is not dependent on any other field. When Function has a value greater than 127(See Appendix B, Table B12), its definition depends on Vehicle System. Function, when combined with the Industry Group and the Vehicle System fields identifies a common name for a specific controller. The common name formed from the combination does not imply any specific capabilities.
2842Vehicle SystemA subcomponent of a vehicle, or a component that is analogous to a subcomponent of a vehicle, that includes one or more SAE J1939 segments and may be connected or disconnected from the vehicle. A Vehicle System may be made up of one or more Functions, which have ECU's that are connected to a SAE J1939 segment of the Vehicle System.

Vehicle System is a 7-bit field defined and assigned by the committee, which when combined with the Industry Group can be correlated to a common name. Vehicle System provides a common name for a group of functions within a connected network. Examples of Vehicle Systems for currently defined Industry Groups are "tractor" in the "Common” Industry Group, “Trailer” in the On-Highway Industry Group, and planter in the "Agricultural Equipment” Industry Group.
2843Vehicle System InstanceVehicle System Instance is a 4-bit field that is used to identify a particular occurrence of a particular Vehicle System within a connected network.

Note that in the case of single or first Vehicle System of a particular type, the instance field should be set to zero indicating the first instance.
2844Arbitrary Address CapableThis 1-bit field indicates whether a CA is both self-configurable and can use an arbitrary source address to resolve an address claim conflict. If this bit is set to “1”, the CA will resolve an address conflict with a CA whose NAME has a higher priority (lower numeric value) by selecting an arbitrary source address from the range 128 to 247 inclusive and claiming that source address. A CA which computes its address but can claim only from a more restricted set of addresses is not considered arbitrary address capable (e.g. On-Highway Trailers.) See section 4.2 of this document for details of the address claim process.
2845NAME of Working Set MemberNAME of Working Set Member

The identifier of the particular CA that is a member of the Working Set identified by the source address of this message. This parameter is a NAME with the format described in 4.1.1.
2846Industry GroupIndustry Group is a 3-bit field defined and assigned by the committee. Industry Group definitions may be found in Appendix B.7 of the SAE J1939 base document. The Industry Group field identifies NAMEs associated with a particular industry that uses SAE J1939, for example: On-Highway Equipment, or Agricultural Equipment.
2847Address Assignment (new source address)This 8 bit field is the 9th byte of the data field of the Commanded Address message. It contains the source address that is to be assigned to the CA that has the NAME corresponding to the one conveyed in the first eight bytes of this Commanded Address message. All messages originating from this CA after reception of the Commanded Address message and successful claim of that address shall use that source address.
2848NAME of Controller Application (for address claimed)An 8-byte value which uniquely identifies the primary function of an ECU and its instance on the network. A device's NAME must be unique, no two devices may share the same NAME value on a given vehicle network.
2849NAME of Commanded Address TargetNAME used to identify Controller Application in a Commanded Address Message to associate the Controller application with an address.
2850Communications AntennaA failure in the antenna system of a communications unit. Note: There are several possible communications devices that might be on a J1939 network, it has been planned that the specific type of communications will be identified by the NAME being used by the CA within the particular ecu. For example the communications antenna on a cellular system would be identified by the antenna SPN being sent from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2851Communications Service Personal Identification NumberThe Personal Identification Number (PIN) is incorrect or has been blocked. Thus service of a particular communications unit is prevented. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example if the PIN was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2852Communications Service Subscriber Identification ModuleThe hardware key, know as a Subscriber Identification Module (SIM), is either missing or incorrect. Thus service of a particular communications unit is prevented. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example if the SIN was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2853Communications ConnectionA communications unit has established connection but no data exchanged has occurred (no other knowledge of why). Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example if the connection problem was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2854Communications CarrierThe communications unit has suffered carrier loss. This failure is generally specific to the Global Sytem for Mobile Communications (GSM), a specific type of cellular communications unit. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example when the carrier problem was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2855Communications Bit Error RateThe data failure rate is too high for communications to keep working at the specified error rate within the specific communications unit in use. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example if the SPN was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2856Communications Data UploadA failure has occurred while sending data using a communications unit from the mobile machine to the fixed base. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN. For example when the failure was for a Cellular communications unit, then the message would come from the SA of the CA with the NAME Function '54' - Communications Unit, Cellular (a radio communications device designed specifically to communicate via the ‘Cellular telephone system’. May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2857Communications Data DownloadA failure has occurred while sending data using a communications unit from the fixed base to the mobile machine. Note: The specific communications unit would be determinable from the NAME of the CA using the SA of the message using this communications SPN.

May be either receiver only, transmitter only or transceiver.) identified within the Global NAME Table.
2858Machine Data Configuration 1There is a problem involving the parameter list (along with the parameter locating information) for the data structure for configuring operations within the Controller Application being communicated with. Note: The specific CA as well as any other information about it would be determinable from the NAME of the CA found by comparing the SA of the particular diagnostic message with the SAs and associated NAMEs from the set of Address Claim messages. For example if the SPN was for an on-board data logger (SA 251, Function 130), then the message would come from the SA of 251, which would be the data logger CA with the NAME Function '130' - identified within the Global NAME Table.
2859Machine Data Configuration 2There is a problem involving one (or more) of the PGN(s) within the parameter list for the data structure for configuring operations within the Controller Application being communicated with.

Said device must also provide the means for the operator to enter and/or adjust said definition.
2878Operators Desired Back-lightA 8 bit parameter to indicate the level of back lighting the operator has selected for displays. This is to be differentiated from the Illumination Brightness Percent (SPN:1487 PGN:53248 Cab Illumination Message) which is sent to the displays to tell them what level to be at. This is the operator desired level (as sensed by operator controls) for those system where the operator controls are monitored by an ecu separate from the ecu sending the command to the displays. Note each display (if appropriate) will need to have its own balance function to compensate its nominal brightness to the same level of that of all other displays. This is especially important for systems with back-lights which may change noticeable with aging. In other words it will be necessary within a vehicle to scale all of the displays down to the same level as the dimmest display (since, obviously you can not make the dimmest brighter).
2879Engine Droop Accelerator 2 SelectIn some off-highway applications it may be desirable to have multiple droop settings available across the range of engine operation. For example, in an agricultural tractor application, this functionality allows a higher engine speed during low load so as to maximize vehicle speed driven between fields on the road. Another use of the droop settings would be to provide functionality for maintaining an engine speed independent of the applied load on demand. There is a normal droop setting, and up to 13 additional preprogrammed droop settings which are user selectable by switching. The selections apply to Accelerator 2.

For example, in an agricultural tractor application, this functionality allows a higher engine speed during low load so as to maximize vehicle speed driven between fields on the road. Another use of the alternate droop settings would be to provide functionality for maintaining an engine speed independent of the applied load on demand. There is a normal droop setting, and up to 13 additional preprogrammed droop settings which are user selectable by switching. The selections apply to Remote Accelerator.

2900Transmission Engine Crank EnableState signal from the transmission indicating if the transmission’s status is such that engine cranking is allowed (i.e. at a minimum, transmission is in neutral and the driveline is disengaged). As sender of this information, the transmission is responsible for correct indication immediately upon first broadcast of this parameter.

As with hard-wired neutral start implementations, those utilizing this parameter should consider the impact of the transmission or other controllers ‘resetting’ due to voltage drops during the engine start sequence.

The vehicle system design should also consider the impact of timing latency in the engine starting sequence. For example, the turn of an ignition key from ‘off’ to ‘start’ may happen more quickly than the transmission controller can boot up, determine its’ current state of being, and begin broadcasting information over the J1939 datalink.

Indicates if conditions are acceptable to obtain a valid transmission oil level measurement as conveyed in SPN 124 Transmission Oil Level or SPN 3027 Transmission Oil Level 1 High / Low. If conditions are not acceptable, this parameter conveys to the operator what prevents conditions from being acceptable. Only one condition can be conveyed in this parameter at any given point in time. If multiple conditions exist, it is not important which condition is actually broadcast, as the driver must ‘correct’ each and every condition as it is presented before a valid oil level reading can be made. If multiple conditions exist that prevent a valid reading, the sender should broadcast one of those conditions until it is corrected; then the next condition can be conveyed to the operator, and so on.

3146PGN of message being configuredThis is the PGN of the Proprietarily Configurable Message (PCM) whose configuration is being identified by this Configuration Identification Message. Operational range includes only those PCMs as identified in the J1939-74 document.
3147Parameter being includedThis is the SPN of the parameter whose location is presently being identified for grouping into the message whose PGN is in this Configuration Identification Message.
3148Position of configured parameterThis is a number identifying a particular parameter’s position within a configured message in particular for differentiating the parameter (identified by SPN) whose location is presently being identified from the other parameters which will be grouped into the message whose PGN is in this Configuration Identification Message. It is used to verify that all of the parameters to be included within the message being configured have been received. A 5 bit slot with the values 0 and 31 is NOT allowed.
3149Message will be used proprietarilyThis is a single bit flag used to indicate that the message being configured is a member of the set of destination specific proprietarily configurable messages, and that hence the Source Address and Destination Address are needed to interpret the data as with the destination specific proprietary A message of -21.
3150Message will use transport protocolThis is a single bit flag used to indicate whether the message being configured is one that will use transport protocol.
3151First parameter only being identifiedThis is a single bit, which is used to identify whether only the first parameter that will be sent within one of the Configurable Messages is being identified with a Configuration Identification Message. This form is to be used on each power-up event for any CA. This function has been generated so that the software can verify that a given message still comes from a particular CA but with the shortest possible initialization times. Identification of the location of individual specific parameters can then be handled with the Parameter Locate message. A "0" means that all the parameters will be transmitted.
3152Number of parameters includedThis is the number of parameters, which will be grouped into the message whose PGN is in this Configuration Identification Message. It is used in the verification that all of the SPNs to be included within the message being configured have been received. A 5 bit slot with 0 and 31 are NOT allowed
3153Starting bit for this parameterThe bit position that the LSB of the data for the parameter, whose SPN is identified in bytes 4-6, is to occupy within the configurable message being identified by the PGN in bytes 1-3. Since this identifies only the position of the LSB it must be remembered that the length is to already be in the CA’s parameter database.
3154Parameter to be locatedThis is the parameter, identified by SPN, that it is desired to locate or to initiate the transmission. Locating implies identifying any message from the given source (i.e. the destination of this Parameter LOCATE MESSAGE), all other CAs when ‘global’ address is used) that contains this particular parameter.
3155Parameter locate commandA byte used to identify the particular command that the Parameter Locate message is presently being used for.
3156Blade Control Mode SwitchThis parameter indicates the blade control mode switch state the user has set for the land leveling system. The switch value directly correlates to the current switch state, regardless of the switch being used. This parameter is intended for use in systems using only one parameter to control the blade movement (i.e. elevation). Systems using two independent parameters to control blade position, i.e. one blade edge maintains a constant elevation and the other blade edge maintains a constant blade angle, should use parameters specific to that usage. Only one of the following states will be active at a time. Below are the data values defined for each switch type that may be used in this application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. A toggle button with two states can be used, in which the button is either in the manual or the auto position at all times. Toggle button usage is as follows:
Manual Position = 0010 Manual button pressed
Auto Position = 0011 Automatic button pressed

2. The momentary rocker switch may be used, where the default is the no button pressed position. The user can press the rocker into the manual position, and when pressure is released, it will return to the no button pressed position. The user may also press the rocker into the auto position, and when pressure is released, it will return to the no button pressed position. Momentary rocker button usage is as follows:
No Button Pressed = 0000 No button pressed
Manual Button Pressed = 0010 Manual button pressed
Auto Button Pressed = 0011 Automatic button pressed

3. The momentary contact button pair may be used, where the default is no buttons being pressed. The user can press the manual button, and when pressure is released, it will return to the no button pressed position. The user may press the auto button, and when pressure is released, it will return to the no button pressed position. Momentary contact buttons (button pair) usage is as follows:

No Button Pressed = 0000 No button pressed
Manual Button Pressed = 0010 Manual button pressed
Auto Button Pressed = 0011 Automatic button pressed

4. The momentary contact single button may be used, where the default is no button being pressed. The user can press the button, which is the button pressed position, and when pressure is released, it will return to the no button pressed position. The controller receiving this command will keep track of what mode the blade is in, auto or manual. When the button is pressed, the "mode button pressed" state is reported and the receiving controller then changes the current mode to its opposite value (i.e. manual to automatic or vise-versa). Momentary contact button (single button) usage is as follows:

No Button Pressed = 0000 No button pressed
Button Pressed = 0001 Mode button pressed

Data Values and Descriptions:

0000 No button pressed
0001 Mode button pressed
0010 Manual button pressed
0011 Automatic button pressed
1110 Error Indicator
1111 Not Installed
All other values are reserved

Notes:
1. The switch state can be read in two ways. One method uses the direct analog switch input to determine the switch state, while the second method relies on a secondary control to read the analog input, then relay the information on the data link. The parameter is designed to provide the actual switch state to other controls that need the information.
2. Other systems with automated blade controls should be able to use this parameter, since it is a measured switch value.
3157Desired Grade Offset SwitchThis parameter indicates the grade offset switch state the user has set for the land leveling system. The desired grade offset value is the vertical offset measured from a given elevation reference point to the bottom edge of the blade. This parameter is intended for use in systems using only elevation offset to control the blade movement (i.e. elevation). Systems using two independent parameters to control blade position, i.e. one edge maintains a constant elevation and the other blade edge maintains a constant angle, should use parameters specific to that usage. Only one of the following states will be active at a time. Below are the data values defined for each switch type that may be used in this application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. The momentary rocker switch may be used, where the default is the no button pressed position. The user can press the rocker into the increment button pressed position, and when pressure is released, it will return to the no button pressed position. The user may also press the rocker into the decrement button pressed position, and when pressure is released, it will return to the no button pressed position. Momentary rocker button usage is as follows:

No Button Pressed = 0000 No button pressed
Increment Button Pressed = 0001 Increment button pressed
Decrement Button Pressed = 0010 Decrement button pressed

2. The momentary contact button pair may be used, where the default is the no buttons pressed position. The user can press the increment button, and when pressure is released, it will return to the no buttons pressed position. The user may press the decrement button, and when pressure is released, it will return to the no buttons pressed position. Momentary contact button (button pair) usage is as follows:

No Button Pressed = 0000 No button pressed
Increment Button Pressed = 0001 Increment button pressed
Decrement Button Pressed = 0010 Decrement button pressed

Data Values and Descriptions:
0000 No button pressed
0001 Increment button pressed
0010 Decrement button pressed

3158Blade Auto Mode CommandAllows other controllers to command to the primary control system what they think is the appropriate auto control mode to be engaged in, based on the information they have available to them. When in automatic mode, the blade automatically adjusts its position to the center of the blade to maintain a desired grade offset. Only one of the following states will be active at a time. Below is extended information describing each command. The purpose of this information is to define what command state should be reported based on what auto control mode command is deemed appropriate by the operational specifications of the system.

0000 Auto Allowed - Auto mode permitted as appropriate (auto button was pushed or directly returned from Suspend Auto condition)
0001 Activity Allows Auto - Auto mode permitted only if the primary control system detects operator activity. The control issuing this command does not have sufficient information/reason to absolutely allow Auto mode (state 0000) or not allow Auto mode (state 0100). The control issuing this command is permitting the primary control system to operate in auto mode only if the primary control system detects operator activity, such as direct input to the primary control system. If the primary control system does not detect operator activity, then the control issuing this command is not allowing auto mode. For example, the control issuing this command has detected no operator activity yet it acknowledges that there may be other sources of operator activity that might make auto mode permissible.
0010 Suspend Auto - Auto mode is temporarily not allowed and the control issuing this command wants the primary control system to automatically return to the previous state (Auto or Manual) when the suspend auto condition is removed.
0011 Service Mode - Auto mode is permitted only for special services such as calibrations.
0100 Auto Not Allowed - Auto mode is not allowed under any condition

Data Values and Descriptions:
0000 Auto Allowed
0001 Activity Allows Auto - must detect operator before auto allowed
0010 Suspend Auto - temporarily suspend auto mode
0011 Service Mode - auto allowed only during service modes
0100 Auto Not Allowed
1110 Error Indicator
1111 Not Supported
All other values are reserved

Note:
The control issuing this command is aware that it does not have access to all information that the primary controller of the Land Leveling System attachment has access to. Therefore, it commands the Land Leveling system to activate a auto blade mode based on the input it has access to. In some cases, like in the "Activity Allows Auto" situation, the control knows the Land Leveling system has access to an additional display (which has switches and several buttons) which may help determine if an operator is present. On the other hand, the control may also have information the primary controller of the Land Leveling System does not have access to, like the parking brake status.

3188XBR Message ChecksumThe XBR message checksum is used to verify the signal path from the demanding device to the brake controller on electronic brake systems. The support of this parameter is mandatory if PGN 1024 is supported as there is no means to indicate “not available”.

The 4 bit XBR message checksum is calculated using the first 7 data bytes, the 4 bit message counter and the bytes of the message identifier. It is calculated as follows:

Checksum = (Byte1 + Byte2 + Byte3 + Byte4 + Byte5 + Byte6 + Byte7 + (message counter & 0x0F) + message ID low byte + message ID mid low byte + message ID mid high byte + message ID high byte)

XBR Message Checksum = ((Checksum >> 4) + Checksum) & 0x0F


Note: A failure in the communication sets the XBR system state:
- to '01' for failed XBR 'priority 01, 10 or 11' messages
- to '10' for failed XBR 'priority 00' messages.
3189XBR Message CounterThe XBR message counter is to verify the signal path from the demanding device to the brake controller on electronic brake systems.. The support of this parameter is mandatory.

Note: The initial value of the 4 bit message counter for the first message during a driving cycle is arbitrary. In every following message the counter is incremented by 1 (0 follows 15).
3190Tire LocationIdentifies which tire is associated with the parametric data in this PGN.

The low order 4 bits represent a position number, counting left to right when facing in the direction of normal vehicle travel (forward).

The high order 4 bits represent a position number, counting front to back on the vehicle.

The value 0xFF indicates not available.

It is recommended that output devices add 1 to the position number (range 1 to 15, not 0 to 14) for use by drivers and service technicians.

Examples: Tire pressure for location 0x00 would be left front tire.

Tire pressure for location 0x23 would be right outside rear rear on a 3-axle tractor with dual axle per side (3rd axle, 4th tire).

3334Left Blade Control Mode Operator ControlThis parameter indicates the left blade control mode operator control state the user has set for the land leveling system. The operator control value directly relates to the current operator control state correlating to the left edge of the blade. The purpose of this parameter is to set the control mode (auto/manual) for the left side of the blade. For this system, the left and right side of the blade can be adjusted independently of each other to either change the elevation from a given reference point or the blade angle (also known as blade tilt)/cross slope depending on the function requested by the operator.

This parameter is intended for use in systems using two parameters (right/left) to control the blade as described above. Systems using only one parameter to control blade position, i.e. elevation, should use the Blade Control Mode Switch parameter. Only one of the following states will be active at a time. In the example below, data values are defined for each switch type that may be used in an application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. A toggle button with two states can be used, in which the button is either in the manual or the auto position at all times.

Toggle button usage is as follows:
Manual Button Pressed = 0010 Manual Operator Control Request
Automatic Button Pressed = 0011 Automatic Operator Control Request
Invalid Switch Input(ex. auto and manual read/pressed simultaneously) = 1110 Error Indicator

2. The momentary rocker switch may be used, where the default is the no button pressed position. The user can press the rocker into the manual position, and when pressure is released, it will return to the no button pressed position. The user may also press the rocker into the auto position, and when pressure is released, it will return to the no button pressed position.

Momentary rocker button usage is as follows:

No button pressed = 0000 No change
Manual Button Pressed = 0010 Manual Operator Control Request
Automatic Button Pressed = 0011 Automatic Operator Control Request
Invalid Switch Input(ex. auto and manual read/pressed simultaneously) = 1110 Error Indicator

3. The momentary contact button pair may be used, where the default is no buttons being pressed. The user can press the manual button, and when pressure is released, it will return to the no button pressed position. The user may press the auto button, and when pressure is released, it will return to the no button pressed position.

Momentary contact buttons (button pair) usage is as follows:

No button pressed = 0000 No change
Manual Button Pressed = 0010 Manual Operator Control Request
Automatic Button Pressed = 0011 Automatic Operator Control Request
Invalid Switch Input(ex. auto and manual read/pressed simultaneously) = 1110 Error Indicator

4. The momentary contact single button may be used, where the default is no button being pressed. The user can press the button, which is the button pressed position, and when pressure is released, it will return to the no button pressed position. The controller receiving this command will keep track of what mode the blade is in, auto or manual. If the blade is in manual mode to begin with, one press of the button will change to mode to auto. If the button is pressed again, the blade will be put into manual mode.

Momentary contact button (single button) usage is as follows:

No button pressed = 0000 No change

3336Left Desired Blade Offset Operator ControlThis parameter indicates the left blade offset operator control state the user has set for the land leveling system. The left desired blade offset value is the offset measured from a given reference point to the bottom left edge of the blade. This parameter will only be used when the control mode for land leveling system has been set to auto. The purpose of this parameter is to adjust the elevation from a given reference point or the blade angle(also known as blade tilt)/cross slope depending on the function being requested by the operator for the left side of the blade.

This parameter is intended for use in systems using two parameters(left/right) to control the blade as described above. Systems using only one parameter to control blade position, i.e. elevation, should use the Desired Blade Offset Switch parameter. Only one of the following states will be active at a time.

In the example below, data values are defined for each switch type that may be used in an application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. The momentary rocker switch may be used, where the default is the neutral position with no buttons pressed. The user can press the rocker into the increment button pressed position, and when pressure is released, it will return to the neutral position.

Notes:

1. The operator control state can be read in two ways. One method uses the direct operator control input to determine the operator control state, while the second method relies on a secondary control to read the operator control input, then relay the information on the data link. The parameter is designed to provide the actual operator control state to other controls that need the information.
2. Other systems with automated blade controls should be able to use this parameter, since it is an actual operator control value.
3338Side-shift Blade Control Mode Operator ControlThis parameter indicates the side-shift offset operator control state the user has set for the land leveling system. When an implement moves in a side-shift direction, it moves from side to side, usually along its longitudinal axis. The desired side-shift offset value is the offset measured from a given vertical reference point to the center of the blade.

Only one of the following states will be active at a time. In the example below, the data values are defined for each switch type that may be used in an application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. The momentary rocker switch may be used, where the default is the neutral position with no buttons pressed. The user can press the rocker into the increment button pressed position, and when pressure is released, it will return to the neutral position. The user may also press the rocker into the decrement button pressed position, and when pressure is released, it will return to the neutral position. Momentary rocker button usage is as follows:

3339Side-shift Desired Blade Offset Operator ControlThis parameter indicates the side-shift blade control mode operator control state the user has set for the land leveling system. When an implement moves in a side-shift direction, it moves from side to side, usually along its longitudinal axis.

The operator control value directly correlates to the current operator control state. Only one of the following states will be active at a time. In the example below, the data values are defined for each switch type that may be used in an application. The purpose of the following switch information is to define what data should be reported based on what type of switch is used.

1. A toggle button with two states can be used, in which the button is either in the manual or the auto position at all times. Toggle button usage is as follows:
Manual Position = 0010 Manual Operator Control Request
Auto Position = 0011 Automatic Operator Control Request

2. The momentary rocker switch may be used, where the default is the no button pressed position. The user can press the rocker into the manual position, and when pressure is released, it will return to the no button pressed position. The user may also press the rocker into the auto position, and when pressure is released, it will return to the no button pressed position. Momentary rocker button usage is as follows:
No Button Pressed = 0000 No Operator Control Request
Manual Button Pressed = 0010 Manual Operator Control Request
Auto Button Pressed = 0011 Automatic Operator Control Request

3. The momentary contact button pair may be used, where the default is no buttons being pressed. The user can press the manual button, and when pressure is released, it will return to the no button pressed position. The user may press the auto button, and when pressure is released, it will return to the no button pressed position. Momentary contact buttons (button pair) usage is as follows:
No Button Pressed = 0000 No Operator Control Request
Manual Button Pressed = 0010 Manual Operator Control Request
Auto Button Pressed = 0011 Automatic Operator Control Request

4. The momentary contact single button may be used, where the default is no button being pressed. The user can press the button, which is the button pressed position, and when pressure is released, it will return to the no button pressed position. The controller receiving this command will keep track of what mode the blade is in, auto or manual. If the blade is in manual mode to begin with, one press of the button will change to mode to auto. If the button is pressed again, the blade will be put into manual mode. Momentary contact button (single button) usage is as follows:
No Button Pressed = 0000 No Operator Control Request
Button Pressed = 0001 Momentary Operator Control Request

Notes:

Voltage droop compensation is used to minimize the amount of reactive current that flows between generators when they are parallelled together. Excessive reactive current will result in the eventual failure of the generator exciter.

IR line compensation increases the generator output voltage as the load increases so the voltage measured at the load will remain constant. Without IR compensation, the voltage measured at the load drops due the IR losses in the power line.

Note:

This parameter sets the mode of regulation for the voltage regulator. The voltage regulator can regulate the generator AC output voltage by using the generator AC output voltage, the generator power factor, or the generator reactive power (VAr). The generator AC output voltage, the generator power factor, and the generator reactive power (VAr) are defined in SAE J1939 - 75

Note:

Underfrequency compensation is when the generator voltage is adjusted based on the generator frequency. Typically generator voltage decreases as frequency decreases. A frequency decrease occurs when load is increased on the genset. Underfrequency compensation decreases the load by reducing the voltage as frequency decreases until a point is reached where the engine can accept more load. Load is applied to the engine when the voltage increases with frequency.

3673Engine Throttle Valve 2 PositionThe sensed position feedback of the valve, coming from a second electrical actuator for a second throttle plate, used to regulate the supply of a fluid, usually air or fuel//air mixture. 0% represents no supply and 100% is full supply. SPN 51 is used for the first throttle position feedback.
3675Engine Turbocharger Compressor Bypass Actuator 1 PositionMeasures the position of the turbocharger compressor bypass actuator, where 0% represents bypass fully closed and 100% represents bypass fully open. Typically, the compressor bypass is used to lower the compressor outlet pressure and/or intake manifold pressure during situations where too much boost is being generated by the turbocharger. Typically, a compressor bypass will be plumbed from the compressor outlet or intake manifold back to the compressor intake, with the compressor bypass actuator and valve in place to regulate bypass flow.
3676Engine Aftercooler Coolant LevelRatio of aftercooler coolant system volume of liquid to total cooling system volume. The engine aftercooler coolant level is for the low temperature (LT) cooling circuit used for the compressor outlet air or charge aftercooling.

SPN 111 "Coolant Level" is assumed to represent a high temperature (HT) cooling circuit used for cooling the engine and its various components.
3677Generator Unavailable to Start / RunIndicates that the generator is not available to start up and run. This may indicate that a shutdown condition is present, or simply that the system has been manually placed into a STOP state.
3678EPS Unavailable to Accept LoadIndicates that the Emergency Power System (EPS) is not prepared to accept load. This implies that the EPS is not in a state that will allow for a quick synchronization and connection to the load bus.
3680Transmission Master ValveThe transmission master valve is in series with a common supply for other transmission valves that control individual functions. They permit overriding the on state of any individual circuit as well as switching on multiple circuits simultaneously.
3681Power Conversion Enable SignalMicrocontroller based systems used in vehicles commonly use managed power down modes. In the event that the operator switches the vehicle off, a system with managed power down may continue to run until that system's requirements for full power down are met.

If the system uses a power supply that operates at a different potential than that of the vehicle, a power conversion function is required. For example, use of a 24v controller in a 12v vehicle would require power conversion to double the nominally 12v power supply.

With a managed power down mode, that power conversion function needs a power conversion enable signal from the microcontroller that it may power down the power conversion independent of the vehicle's power down.
3682Transmission Air Pressure Regulator ValveThe valve used to regulate the air supply pressure for the transmission.
3683Steering Wheel AngleThe main operator`s steering wheel angle (on the steering column, not the actual wheel angle). The vehicle being steered to the left (counterclockwise) results in a positive steering wheel angle. This is the yaw angle of the steering wheel with the z-axis along the centerline of the steering column. This parameter is defined according to a Z-Up axis system and the sign of the value is in accordance to the right-hand rule, as specified in SAE J670. As specified in SAE J670, a Z-Up Axis System has positive X directed forward, positive Y to the left, and positive Z directed up.
3684Steering Wheel Angle Range CounterThe signal indicates the number of steering wheel angle range overflows if the operating range of steering wheel is greater than the measuring range of sensor element. Positive values indicate left turns (counterclockwise). If the steering wheel angle range is +/-180 degrees this signal is equivalent to a steering wheel turn counter. This parameter is defined according to a Z-Up axis system and the sign of the value is in accordance to the right-hand rule, as specified in SAE J670. As specified in SAE J670, a Z-Up Axis System has positive X directed forward, positive Y to the left, and positive Z directed up.
3685Steering Wheel Angle Range Counter TypeThe signal indicates whether the steering wheel angle sensor is capable of absolute measuring of the number of steering wheel angle ranges or not. Absolute measuring means that the steering wheel angle range counter signal indicates the real position of steering wheel at ignition on. Relative measuring means that the steering wheel angle range counter signal is zero at ignition on independent of the real position of steering wheel.

00 - relative number of counts
01 - absolute number of counts
10 - not defined
11 - signal not available
3686Steering Wheel Angle RangeThe signal indicates the range of the steering wheel angle the sensor element is capable to measure. The steering wheel angle signal ranges between the negative and the positive value of the steering wheel angle range.

For example, a steering angle sensor transmits +13.6 rad to indicate a range of +/- 13.6 rad.
3687Steering Angle Sensor Active ModeThis signal indicates the operational mode of the steering angle sensor.

00 – Programming mode active
01 – Normal mode active
10 – Reserved
11 – Not available
3688Steering Angle Sensor CalibratedThis signal indicates the calibration status of the steering angle sensor.

00 – SAS not calibrated
01 – SAS calibrated
10 – Reserved
11 – Not available
3689Message CounterThe message counter is to verify the signal path from the demanding device to the steering controller. The support of this parameter is mandatory.

Note: The initial value of the 4 bit message counter for the first message during a driving cycle is arbitrary. In every following message the counter is incremented by 1 (0 follows 15).
3690Message ChecksumThe message checksum is used to verify the signal path from the demanding device to the steering controller. The support of this parameter is mandatory if PGN 61469 is supported as there is no means to indicate “not available”.

The 4 bit checksum is the sum of the high nibble and the low nibble of the sum of the identifier, the first 7 data bytes and the 4 bit message counter. It is calculated as follows:

Checksum = (Byte1 + Byte2 + Byte3 + Byte4 + Byte5 + Byte6 + Byte7 + (message counter & 0x0F) + message ID low byte + message ID mid low byte + message ID mid high byte + message ID high byte)

Checksum = ((Checksum >> 4) + Checksum) & 0x0F

3783Intake Manifold Charge CombustionThis parameter provides diagnostics on a charge combustion event within the engine intake manifold, which is commonly called spit-back or intake manifold backfire. This combustion event may be caused by factors such as burnt or sticking intake valves, by ignition timing errors in the case of spark ignition engines, and others. This combustion event may occur without warning at any time on a running engine. A pressure switch or transducer that is fitted directly into the intake manifold to detect the first rising pulse and cause lockout will provide protection against further engine damage.

4099XBR urgencyThe idea of the urgency value is to adjust the endurance brake integration behavior in the EBS system according to the traffic situation.

On low urgency values (0%, e.g. downhill cruise control or preceding vehicle far ahead) the brake system shall primarily use endurance brakes to reduce lining wear.

On high urgency values (100%, e.g. vehicle close up or a vehicle cuts into the traffic line just before host vehicle) the brake system is expected to gain the demanded deceleration (acceleration) as fast as possible.

Values:
0% - Situation not critical; low retarder dynamics are tolerated. Activation of the foundation brakes after a time if retarder performance is insufficient
y % - Faster activation of foundation brakes to compensate retarder performance, linear interpolation between 0 and 100%
100% - Low retarder dynamics shall be fully compensated by the foundation brakes

Notes:
- This parameter has only an effect if XBR EBI switch is set to "10: endurance brake integration allowed"
- XBR urgency makes sense only if the XBR request(s) is (are) processed in one device like the EBS controller which also sends TSC1 to the retarder(s). Such a data flow diagram is shown in figure PGN1024_A. When the Retarder is controlled directly by the XBR transmitter XBR urgency should be set to not available.

In adaptive cruise control (ACC) operation there are situations where it is useful to have as less lining wear as possible like keeping the set speed on going downhill. It would not be useful to activate foundation brakes in such a situation except when the capabilities of the endurance brakes are not sufficient.

In other situations like emergency braking or fast reaction on a car that cut in at a short distance in front of the own vehicle a reaction as fast as possible is needed. In such cases low retarder dynamics must be compensated by the foundation brakes.

There are two different ways to integrate the endurance brakes into the adaptive cruise control.
a) the request for deceleration could be processed by the EBS system completely. This means that the EBS receives the deceleration demand and activates the friction and/or the endurance brakes accordingly. EBS is sending the TSC1 to the retarder. (see figure PGN1024_A dataflow diagram for external brake request)
b) the ACC sends XBR to the brake controller and TSC1 to the endurance brakes.

In case "a)" the ACC system does not have direct control of the endurance brakes. To adjust the endurance brakes according to the traffic situation (high or low urgency values see above) this new SPN is needed.

If the retarder performance is not sufficient (e.g. because of high retarder temperature) the foundation brakes will be added automatically. This case of not sufficient retarder performance cannot be covered by switching EBI mode from 01 (endurance brakes only) to EBI mode 10 (endurance brake integration allowed) because the actual deceleration caused by the retarder is less than the requested decelleration. A simple switching (01 to 10) would cause an uncomfortable jerk.

4206Message CounterThe message counter is used to detect situations where the transmitting ECU malfunction repeats the same frame all the time. The receiver of the information may use the counter parameter to detect this situation. The transmitting device will increase the message counter in every cycle. The message counter will count from 0 to 7 and then wrap.

The values 0x8 thru 0xE are SAE reserved and should be ignored by the receiver.

Value 0xF (all bits set to 1) will indicate that the message counter is not available. For compatibility purposes, TSC1 should also be honored if the message counter is not available from the transmitting device.
4207Message ChecksumThe message checksum is used to verify the signal path from the transmitting device to the receiving device.

The message checksum is calculated using the first 7 data bytes, the message counter and the bytes of the message identifier. It is calculated as follows:

Checksum = (Byte1 + Byte2 + Byte3 + Byte4 + Byte5 + Byte6 + Byte7 + (message counter & 0x0F) + message ID low byte + message ID mid low byte + message ID mid high byte + message ID high byte)

Message Checksum = (((Checksum >> 6) & 0x03) + (Checksum >>3) + Checksum) & 0x07

Value 0xF (all bits set to 1) will indicate that the checksum is not available. For compatibility purposes, TSC1 should also be honored if the checksum is not available from the transmitting device.

4242Transmission Reverse Gear Shift Inhibit Requesttransmission responses occur regardless of shift selector (Forward, Neutral or Reverse) position at the time the request is received.

This request would typically come from a component wishing to override the vehicle operator’s ability to shift or keep the transmission in Reverse. For example, the control system of a rear-loading refuse packer may wish to prevent shifts to reverse when it detects the presence of someone behind the vehicle.

Reverse gear shift inhibits include all ‘Neutral-to-Reverse’ shifts and ‘Forward-to-Reverse’ shifts; the ability of the transmission to complete ‘Neutral-to-Forward’ or ‘Forward-to-Forward’ gear shifts is not impacted.

If the transmission is in Reverse or attempting to shift to Reverse and receives an active Reverse gear shift inhibit request (0b01), the transmission will shift to Neutral. When the request subsequently goes inactive (0b00), the transmission will remain in Neutral until it receives a selector input from the vehicle operator requesting it to shift into a Non-Neutral gear. The transmission should not automatically return to the previous gear when this signal goes inactive.

Transmission response to this request can be monitored via SPN 4261 – Transmission Reverse Gear Shift Inhibit Status, SPN 523 Transmission Current Gear, and SPN 524 Transmission Selected Gear.

00 = Allow shifts into Reverse gear
01 = Inhibit shifts into Reverse gear, and shift transmission to Neutral if already in Reverse or attempting to shift to Reverse

4255Transmission Requested Launch GearInitial gear for the transmission to start out in when the vehicle is launched from a standing stop, as specified by the vehicle operator or vehicle system. Automatic transmissions typically default to starting out in 1st gear. However, in applications such as those with very low gearing, it is desirable to launch the vehicle in a range higher than 1st. For example, when the vehicle has little or no payload, the operator may wish to launch from 2nd or 3rd gear to avoid stacked, unnecessary shifts in the lower ranges.

The intent of SPN 4255 is to request the initial starting range to be used when the vehicle gets underway from a stop; it does not request direction changes (forward / reverse). SPN 525 sets the direction requested by the operator. For example, if SPN 525 is requesting a Reverse range, any SPN 4255 value indicating a desired forward launch gear would be ignored by the transmission controller. The SPN 4255 value is only utilized by the transmission controller when its direction matches that of the current SPN 525 value.

0000 = No specific launch gear requested; use default launch gear
0001 = Launch the vehicle in 1st gear

4750Engine Exhaust Gas Recirculation 1 Cooler Intake TemperatureExhaust Gas Recirculation (EGR) Temperature measured at the EGR cooler intake. See SPN 412 for Engine EGR temperature which is typically measured at the EGR cooler outlet.
4751Engine Exhaust Gas Recirculation 1 Cooler Intake Absolute PressureExhaust gas recirculation absolute pressure is measured at the EGR cooler intake. See SPN 3358 for EGR pressure measured at the EGR cooler outlet before the valve.
4752Engine Exhaust Gas Recirculation 1 Cooler EfficiencyExhaust Gas Recirculation cooler efficiency is an indication of the cooler’s ability to reduce the temperature of the exhaust gas that is being recirculated back to the intake. 0% = no reduction in temperature, 100% = maximum cooling. The EGR cooler efficiency is calculated as (EGR cooler intake temperature minus EGR gas temperature) divided by (EGR cooler intake temperature minus engine coolant temperature).
4753Aftertreatment 1 Gas Oxidation Catalyst Intake TemperatureTemperature of engine combustion byproducts entering the gas oxidation catalyst in exhaust bank 1. This parameter should be used with engines fueled by gaseous fuel like natural gas or propane. A separate parameter has been defined for diesel fueled engines.
4754Aftertreatment 1 Gas Oxidation Catalyst Outlet TemperatureTemperature of engine combustion byproducts leaving the gas oxidation catalyst in exhaust bank 1. This parameter should be used with engines fueled by gaseous fuel like natural gas or propane. A separate parameter has been defined for diesel fueled engines
4755Aftertreatment 1 Gas Oxidation Catalyst Differential PressureExhaust differential pressure measured between the intake and exhaust of the gas oxidation catalyst in exhaust bank 1. This parameter should be used with engines fueled by gaseous fuel like natural gas or propane. A separate parameter has been defined for diesel fueled engines.
4756Aftertreatment 1 Gas Oxidation Catalyst Intake Temperature Preliminary FMIUsed to identify the applicable J1939-73 FMI detected in the gas oxidation catalyst intake temperature sensor by the manufacturer’s sensor control software in exhaust bank 1.

5603Cruise Control Disable CommandThis parameter is used to disable cruise control from a source other than the driver controlled switch if cruise control is active. It is also used to inhibit cruise control from becoming active if it is not currently active. If this parameter is used to disable cruise control, then cruise control will need to be re-initialized and the previous set speed will not be retained.

This parameter has priority over Cruise Control Resume Command (SPN 5604). See Figure PGN2560_A for an explanation of how this relates to other parameters.

Use of this parameter is in addition to Cruise Control Enable Switch (SPN 596). The Cruise Control Enable Switch set to OFF has priority over the Cruise Control Disable Command set to allowed.

This parameter is not the physical switch that enables cruise control. See SPN 596 for the physical switch.

5605Cruise Control Pause CommandThis parameter is used to temporarily disable cruise control from a source other than the driver controlled switch if cruise control is active. If this parameter is used to disable cruise control, then cruise control will not need to be re-initialized and the previous set speed will be retained. In order for the cruise control system to resume to the previous set speed, a valid command must be received. Valid commands include (1) the Cruise Control Resume Switch (SPN 601), (2) the Cruise Control Set Switch (SPN 599), or (3) Cruise Control Resume Command (SPN 5604).

This parameter has priority over Cruise Control Resume Command (SPN 5604). See Figure PGN2560_A for an explanation of how this relates to other parameters.

This parameter is not the physical switch that is used to pause cruise control. See SPN 1633 for the physical switch.

5666NM Control Mode IndicatorThis four bit parameter is used to define the purpose of the NM message as follows:

Mode 0 – Set Pending NAME

This form of the message is the command to the target CA at the destination address in the CAN Identifier to change its pending NAME to the one contained in the message. All data fields of the message are required.

The “Commanded” parameter fields are the new (i.e. commanded) NAME field values. These shall be qualified with the qualifier flags. A value of “0” in the qualifier flags indicates that the associated field should be changed to the value in the corresponding parameter field in the message. A value of “1” indicates that the associated field should remain unchanged.

The NAME checksum byte contains the arithmetic sum of the 8 bytes of the target CAs original NAME truncated to 8 least significant bits. This is used as a security check to make sure the command message has been received by the correct CA. This check guards against the possibility of the SA having changed through the address arbitration process.

Mode 1 – Pending NAME

This form of the message is sent by the target CA and is a response to a request for “pending” NAME. The CA’s pending NAME is contained in the “Commanded” parameter fields. All “Commanded” parameter fields of the NAME are required. The qualifier flags and NAME checksum are not used and shall be set to all 1s. If the Pending NAME has not been set or is not valid, this form of the message shall not be sent. Rather, the NACK (mode 4) shall be sent.

Mode 2 – Current NAME

This form of the message is sent by the target CA and is a response to a request for “current” NAME. The CA’s current NAME is contained in the “Commanded” parameter fields. All fields of the NAME are required. The qualifier flags and NAME checksum are not used and shall be set to all 1s.

Mode 3 – NAME ACK

This form of the message is sent by the target CA indicating the most recently received “Set Pending NAME” command has been successfully fulfilled. The CA’s pending NAME is contained in the “Commanded” parameter fields. All “Commanded” parameter fields of the NAME are required. The qualifier flags and the NAME checksum are not used and shall be set to all 1s.

Mode 4 – NAME NACK

This form of the message is sent by the target CA indicating the most recently received “Set Pending NAME” command or “Request Pending NAME” command was not successful. The control mode parameter and the Error Code parameter are the only valid fields in this form of the message. All other fields shall be set to all 1s.

Mode 5 – Request Pending NAME

This form of the message is sent by the commanding CA and is a request for the target CA to respond with its “pending” NAME. The control mode parameter is the only valid field in this form of the message. All other fields shall be set to all 1s.

Mode 6 – Request Current NAME

This form of the message is sent by the commanding CA and is a request for the target CA to respond with its “current” NAME. The control mode parameter is the only valid field in this form of the message. All other fields shall be set to all 1s.

Mode 7 – Adopt Pending NAME

This form of the message is sent by the commanding CA and is a “trigger” command to the targeted CA, (or all CAs with pending NAMEs if sent to the global address) to adopt their pending NAME as its current NAME and to initiate the Address Claim procedure with this new NAME. The control mode parameter is the only valid field in this form of the message. All other fields are set to all 1s. This form of the message may be sent to a specific SA or to the global address.

Mode 8 – Request NAME Address Claim

This form of the message is used to request that a CA whose SA is unknown to the requester send the address claim message, thus allowing the requester to determine the CA’s SA. All or portions of the NAME may be specified in the request using the qualifier flags. This form of the message shall be sent to the global address.

If a CA receives this request and the indicated qualifier fields match the current NAME, it shall send its address claim using its current NAME. If a CA receives this request but it doesn’t match the indicated fields of the current NAME, it shall not send an address claim and shall not send the NAME NACK form of the NM message.

Modes 9-15 – reserved for future SAE use.
5667Commanded Manufacturer CodeThe target CA shall use this 11 bit value for the Manufacturer Code if the corresponding qualifier flag in Byte 2 is set to “0”.

The least significant bit is in bit 6 of byte 3 and the most significant bit of the manufacturer Code is located in bit 8 of byte 4.
5668Commanded ECU InstanceThe target CA shall use this 3 bit value for its ECU Instance field if the corresponding qualifier flag in Byte 2 is set to “0”.
5669Commanded Function InstanceThe target CA shall use this 5 bit value for its Function Instance if the corresponding qualifier flag in Byte 2 is set to “0”.
5670Commanded FunctionThe target CA shall use this 8 bit value for its Function field if the corresponding qualifier flag in Byte 2 is set to “0”.
5671Commanded Vehicle SystemThe target CA shall use this 7 bit value for its Vehicle System field if the corresponding qualifier flag in Byte 2 is set to “0”.
5672Commanded Vehicle System InstanceThe target CA shall use this 4 bit value for its Vehicle System Instance field if the corresponding qualifier flag in Byte 2 is set to “0”.
5673Commanded Industry GroupThe target CA shall use this 3 bit value for its Industry Group field if the corresponding qualifier flag in Byte 2 is set to “0”.
5674Commanded Arbitrary Address CapableThe target CA shall use this 1 bit value for its Arbitrary Address Capable field if the corresponding qualifier flag in Byte 2 is set to “0”.

001 - low probability for a bend off maneuver of the relevant object
010 - medium probability for a bend off maneuver of the relevant object
011 - high probability for a bend off maneuver of the relevant object
100 - highest probability for a bend off maneuver of the relevant object
101 - relevant object is already in a turning maneuver
110 - error indication
111 - signal not available / not installed
5680Time to collision with relevant objectThe time to collision is the duration after which the predicted travelling paths of host vehicle and relevant object lead to a distance of 0m between both.

Note: It is up to the system manufacturer to choose a suitable calculation method to predict the travelling paths of both host vehicle and relevant object.
5681Driver activation demand for Advanced Emergency Braking SystemAccording to the Vienna world convention on road traffic the driver must be provided with means to deactivate an Advanced Emergency Braking System. This command is to be transmitted from the respective HMI unit to the AEBS unit.

00 - the driver does not want the Advanced Emergency Braking System to warn or intervene at any time (deactivation of system)
01 - the driver wants the Advanced Emergency Braking System to warn or intervene if necessary (no deactivation of system)
10 - reserved
11 - don’t' care / take no action

Note: The signal has to be transmitted permanently to the AEBS showing the state selected once by the driver. Typically there is a deactivation push button present in the host vehicle for the driver to choose this state.

Example: After ignition-on the signal is being transmitted as 01b (this will be the default state in Europe) all the time. As soon as the driver depresses the push button the signal's value has to change to 00b for the remaining ignition cycle as long as the driver does not depress the push button again.
5682AEBS2 message CounterThe message counter is increased with every transmitted AEBS2 message. After reaching a value of 0xF the next value will be 0.
5683AEBS2 message checksumUsed to check the message checksum of the transmitting (HMI) unit within the AEBS2 system.

Checksum = (Byte1 + Byte2 + Byte3 + Byte4 + Byte5 + Byte6 + Byte7 + (message counter & 0x0F) + message ID low byte + message ID mid low byte + message ID mid high byte + message ID high byte)

Message Checksum = ((Checksum >> 4) + Checksum) & 0x0F
5684Reference Engine Gas Mass Flow RateConfiguration of the mass flow rate of gaseous fuel expected for 100% engine fuel valve control command.

5793Desired Engine Fueling StateDevices send this request to the engine controller to:

(a) Shut off engine fueling, but remain prepared to re-start quickly by not shutting down the control system, or
(b) Keep the engine running.

00 Fueling not desired (shut off engine fueling)
01 Fueling desired (keep engine running)
10 Parameter supported, but no request
11 Don't care / Take no action

If the engine controller receives this parameter from multiple sources, then '01-Fueling desired' shall have priority over '00-Fueling not desired'.

If this request can be honored by the receiving device as indicated by SPN 5795, then it shall be processed independently of other means to stop engine fueling (i.e., SPN 970 Engine Auxiliary Shutdown Switch or the Keyswitch). For example, if the engine is acting on SPN 5793 set to 01 (keep engine running) and the vehicle keyswitch is turned off, then the engine shall shut off.

Use examples of this parameter include, but are not limited to:
1. In applications or situations where the engine can be physically disconnected from the hybrid powertrain, a command of 00 could be used to request the engine to stop running, and as a result, stop rotating.
2. In applications or situations where engine-driven accessories (power steering, etc.) must remain active while the engine is not running, a command of 00 could result in the engine no longer running even as it continues to be spun (motored) by the hybrid powertrain.
3. In applications or situations where components want to keep the engine running, such as an aftertreatment system, a command of 01 could be used to prevent the engine from honoring requests from other devices using this parameter to shut off fueling.
5794Feedback Engine Fueling StateThis parameter provides feedback to the network that SPN 5793 Desired Engine Fueling State was honored. SPN 5795 Engine Fueling Inhibit Allowed indicates the engine’s current ability to honor requests via SPN 5793 Desired Engine Fueling State.

00 = Fueling is or will be inhibited (SPN 5793 Desired Engine Fueling State = 00 from at least one network device and all other network devices have SPN 5793 Desired Engine Fueling State equal to something other than 01)
01 = Engine will be kept running (SPN 5793 Desired Engine Fueling State = 01 from at least one network device)
10 = No active request per SPN 5793 Desired Engine Fueling State or SPN 5795 Engine Fueling Inhibit Allowed = 00. When SPN 5795 = 00, then requests via SPN 5793 Desired Engine Fueling are ignored.
11 = Not Supported
5795Engine Fueling Inhibit AllowedThis parameter is broadcast by the engine control system, and indicates to other devices on the network whether or not it will respond to requests to inhibit engine fueling via SPN 5793 Desired Engine Fueling State. With this information, devices that may wish to inhibit engine fueling at some time in the future can know whether or not their request will be honored before they issue a request.

This parameter does not reflect the state of the engine controller due to requests received in SPN 5793 Desired Engine Fueling State.

This parameter is intended to be used in conjunction with SPN 5793 Desired Engine Fueling State and SPN 5794 Feedback Engine Fueling State.

00 = Engine currently will not stop fueling in response to SPN 5793 Desired Engine Fueling State
01 = Engine will stop fueling in response to SPN 5793 Desired Engine Fueling State
10 = SAE Reserved
11 = Not Supported

5825Driver Warning System Indicator StatusThe desired illumination of the Euro VI defined driver warning system indicator for relevant malfunctions and diesel exhaust fluid (reagent) tank low level. Used for Euro VI implementations. See Euro VI implementing regulation Annex XIII, Section 4 for usage requirements.

000 - Off - Used when driver warning system is non-active - which, by requirement, means the low-level and severe inducement systems are also non-active
001 - On – solid - Used when driver warning system is activated for any relevant malfunction
010 - reserved for SAE assignment
011 - reserved for SAE assignment
100 - On – fast blink (1 Hz) - Used for the second driver warning system detection threshold for diesel exhaust fluid level, where the visual alarm of the driver warning system is required to "escalate in intensity"
101 - reserved for SAE assignment
110 - reserved for SAE assignment
111 - not available

Note: SPN 5825 is similar to SPN 5245.

5913Transmission Oil Temperature 2Second instance of transmission lubricant temperature. This parameter may reflect the temperature of a second sump or oil supply. If only one instance of transmission lubricant temperature measurement exists, SPN 177 Transmission Oil Temperature 1 should be used.
5914Transmission Oil Level 2 High / LowSecond instance of a transmission oil level indicator. Conveys the current volume of transmission sump oil compared to recommended volume. Positive values indicate overfill. Zero means the transmission fluid is filled to the recommended level. If only a one instance of transmission oil level measurement exists, SPN 3027 Transmission Oil Level 1 High / Low should be used.

Parameter Specific Indicator:
A value of 0xFB indicates conditions are not acceptable for a valid fluid level measurement.
5915Transmission Oil Level 2 Countdown TimerCountdown timer for the second instance of a transmission oil level indicator. Once all vehicle conditions (such as vehicle stopped, etc) are met, some transmissions may require a ‘settling time’ to allow the fluid level to normalize. This parameter indicates how much of the required settling time remains. When time reaches 0, a valid oil level measurement value will be broadcast in SPN 5914 Transmission Oil Level 2 High / Low. If only a single oil level is measured, SPN 3028 Transmission Oil Level 1 Countdown Timer should be used.

5916Transmission Oil Level 2 Measurement StatusMeasurement status for the second instance of a transmission oil level indicator. Indicates if conditions are acceptable to obtain a valid transmission oil level measurement as conveyed in SPN 5914 Transmission Oil Level 2 High / Low. If conditions are not acceptable, this parameter conveys to the operator what prevents conditions from being acceptable. Only one condition can be conveyed in this parameter at any given point in time. If multiple conditions exist, it is not important which condition is actually broadcast, as the driver must ‘correct’ each and every condition as it is presented before a valid oil level reading can be made. If multiple conditions exist that prevent a valid reading, the sender should broadcast one of those conditions until it is corrected; then the next condition can be conveyed to the operator, and so on. If only a single oil level is measured, use SPN 3026 Transmission Oil Level 1 Measurement Status.
