MODULE NETWORK INPUT MESSAGES - ABS MODULE
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| ACC_brake deceleration request | C-CM | The adaptive cruise control system uses the ABS for braking. This message is used to alert the ABS that the adaptive cruise control system needs to decelerate and/or brake. |
| Accelerator pedal position | PCM | The ABS module uses accelerator pedal position information for correct operation of the traction control, ESC, RSC and hill descent control systems. |
| AWD lock status | PCM | The ABS module disables some vehicle dynamic systems and increases the minimum threshold for other vehicle dynamic systems when the AWD system is engaged. |
| AWD torque actual | PCM | The ABS module can request that the transfer case be disengaged in the event that ESC intervention is necessary. The ABS module needs to know the actual torque being applied to the AWD system before requesting the transfer case to be disengaged. |
| Brake pedal applied | PCM | This message informs the ABS module that the driver has pressed the brake pedal. This message is also used by the ABS module to check the brake pressure sensor located inside the HCU. |
| Car mode | BCM | The vehicle dynamic system reacts differently depending on the current car mode; normal, factory, transport or crash. This message informs the ABS module of the current car mode. |
| Cruise control override | PCM | This message informs the ABS module that the PCM has denied the driver requested cruise control activation. |
| Cruise control status | PCM | This message informs the ABS module of the current status of the cruise control system; off, denied, standby or active. |
| Drivers door ajar status | BCM | The ABS module resets the parameters used for the RSC function when the driver door is opened. |
| Drivers rear door ajar status | BCM | The ABS module resets the parameters used for the RSC function when the driver rear door is opened. |
| Engine off | BCM | This message informs the ABS module that the engine is no longer running. |
| EPAS failure | PSCM | The ABS uses steering angle information from the PSCM for ESC and RSC. This message informs the ABS module that there is an internal error in the PSCM. |
| Hood ajar status | BCM | The ABS module resets the parameters used for the RSC function when the hood is opened. |
| Ignition status | BCM | This message informs the ABS module of the current ignition status; off, accessory, run, start, invalid or unknown. |
| Liftgate ajar status | BCM | The ABS module resets the parameters used for the RSC function when the liftgate is opened. |
| Passenger door ajar status | BCM | The ABS module resets the parameters used for the RSC function when the passenger door is opened. |
| Passenger rear door ajar status | BCM | The ABS module resets the parameters used for the RSC function when the passenger rear door is opened. |
| RCM serial number | RCM | The ABS module stores the RCM serial number and verifies the serial number when the vehicle is started or the ignition is set to run or accessory. Over time, the ABS module learns the offset of the sensors inside the RCM. When a new serial number is found, the ABS module resets the offset number learned for RSC. |
| Selector lever (PRNDL) status | PCM | This message provides the ABS module with the current transaxle gear status. The ESC and RSC functions do not operate when the transaxle is in REVERSE. |
| Selector lever (PRNDL) status | TCM (2.0L GTDI Only) | This message provides the ABS module with the current transaxle gear status. The ESC and RSC functions do not operate when the transaxle is in REVERSE. |
| Steering angle calibration | PSCM (vehicles without active park assist) | This message indicates at what angle the steering wheel is turned. |
| Steering angle calibration | SCCM (vehicles with active part assist) | This message indicates at what angle the steering wheel is turned. |
| Steering angle count | PSCM (vehicles without active park assist) | The ABS module uses this message to determine the validity of the steering angle sensor signal. |
| Steering angle count | SCCM (vehicles with active part assist) | The ABS module uses this message to determine the validity of the steering angle sensor signal. |
| Steering angle initialization | PSCM (vehicles without active park assist) | This message indicates at what angle the steering wheel is turned. |
| Steering angle initialization | SCCM (vehicles with active part assist) | This message indicates at what angle the steering wheel is turned. |
| Traction control on/off | IPC | This message informs the ABS module that the driver has requested the traction control portion of the vehicle dynamic system be disabled or enabled. |
| Trailer sway configuration command | IPC | Informs the ABS module that the driver has turned the trailer sway control on or off. |
| Transmission shift in progress | PCM | This message is used by the ABS module for traction control performance. |
| Transmission shift in progress | TCM (2.0L GTDI Only) | This message is used by the ABS module for traction control performance. |
| Vehicle configuration data_Axle ratio | BCM | This message informs the ABS module of the current vehicle axle ratio. This information allows the ABS module to calculate wheel speed information before sending it out on the HS-CAN . |
| Vehicle configuration data_Collision mitigation by braking | BCM | This message informs the ABS module that the vehicle is equipped with the collision warning system. |
| Vehicle configuration data_Cruise control | BCM | This message informs the ABS module that the vehicle is equipped with cruise control. |
| Vehicle configuration data_Engine fuel capability | BCM | This message informs the ABS module of the current vehicle fuel type, gasoline or diesel. |
| Vehicle configuration data_Forward collision warning | BCM | This message informs the ABS module that the vehicle is equipped with the collision warning system. |
| Vehicle configuration data_Four wheel drive type | BCM | This message informs the ABS module that the vehicle is equipped with 4WD . The vehicle dynamic system will react differently when the 4WD system is activated. |
| Vehicle configuration data_Gearbox type | BCM | This message informs the ABS module of the type of transaxle the vehicle is equipped with, manual or automatic transaxle. |
| Vehicle configuration data_Keyless entry and start | BCM | This message informs the ABS module if the vehicle is equipped with IA. |
| Vehicle configuration data_ RCM aux id | BCM | This message is a redundancy of the RCM serial number message. |
| Vehicle configuration data_Steering wheel location | BCM | This message informs the ABS module of the steering wheel location, LH drive or RH drive. |
| Vehicle configuration data_Tire size | BCM | This message informs the ABS module of the current vehicle tire size. This information allows the ABS module to calculate wheel speed information before sending it out on the HS-CAN . |
| Vehicle configuration data_ VIN number | BCM | This message informs the ABS module of the current VIN. The ABS stores the VIN and will set a DTC if the stored VIN does not match the vehicle configuration data message. |
