ABS MODULE NETWORK INPUT MESSAGES
| Broadcast Message | Originating Module | Message Purpose |
|---|---|---|
| Accelerator pedal position | PCM | The ABS module uses accelerator pedal position information for correct operation of the traction control and ESC systems. |
| Adaptive cruise control brake precharge request | C-CM | The adaptive cruise control system uses the ABS module for braking. This message is used to alert the ABS module that the adaptive cruise control braking event requires a precharge of the hydraulic system. |
| Adaptive cruise control brake request | C-CM | Used to alert the ABS module that the adaptive cruise control system needs to brake. |
| Adaptive cruise control deceleration request | C-CM | Used to alert the ABS module that the adaptive cruise control system needs to decelerate. |
| Adaptive cruise control monitor error | BCM | Used to alert the ABS module that there is an error in the adaptive cruise control system. |
| Brake pedal applied | PCM | Used to inform 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. |
| Brake switch on/off | PCM | Used to inform 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 stability control 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. |
| Collision mitigation by braking brake precharge request | C-CM | The collision mitigation by braking system uses the ABS module for braking. Used to alert the ABS module that the collision mitigation by braking event requires a precharge of the hydraulic system. |
| Collision mitigation by braking brake request | C-CM | Used to alert the ABS module that the collision mitigation by braking system needs to brake. |
| Collision mitigation by braking deceleration request | C-CM | This message is used to alert the ABS module that the collision mitigation by braking system needs to decelerate. |
| Collision mitigation by braking monitor error | BCM | Used to alert the ABS module that there is an error in the collision mitigation by braking system. |
| Cruise control mode | PCM | Used to inform the ABS module of the current cruise control mode; not active, keeping speed, accelerating, decelerating, resuming high, resuming low, tap up waiting or tap down waiting. |
| Cruise control override | PCM | Used to inform the ABS module that the PCM has denied the driver requested cruise control activation. |
| Cruise control status | PCM | Used to inform the ABS module of the current status of the cruise control system; off, denied, standby or active. |
| Engine off status | PCM | Used to inform the ABS module that the engine is no longer running. Engine RPM PCM Used to inform the ABS module of the current engine RPM. The ABS module uses this information for traction control and ESC system operations. |
| Ignition status | BCM | Used to inform the ABS module of the current ignition status; off, accessory, run, start, invalid or unknown. |
| 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 ESC operation. |
| Selector lever (PRNDL) status | PCM | This message provides the ABS module with the current transmission gear status. The ESC function does not operate when the transmission 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 park 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 park 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 park 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 system be disabled or enabled. |
| Transmission shift in progress | PCM | 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_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. |
| Wheel torque data | PCM | Used to inform the ABS module of the current drive wheel torque output in Newton meters. This message is used by the ABS module for traction control and ESC performance. |
