| Accelerator pedal position |
PCM |
This message is sent to the GWM and then to the ABS module. The ABS module uses accelerator pedal position information for correct operation of the traction control, Electronic Stability Control (ESC) and hill start assist systems. |
| AWD locking status |
PCM |
This message is sent to the GWM and then to the ABS module. The ABS module uses AWD information for correct operation of the ABS and stability control systems. |
| Brake on/off switch |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module 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 pedal applied |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module 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. |
| Clutch pedal position |
PCM |
This message is sent to the GWM and then to the ABS module. This message is used by the ABS module for the hill start assist system. |
| Collision mitigation by braking deceleration |
CCM |
This message is used to request vehicle deceleration by the ABS module for the collision avoidance system. |
| Door ajar status |
BCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current door ajar status. There is a separate message for each door. The ABS module resets the parameters used for the Electronic Stability Control (ESC) function when a door is opened. |
| Engine disable status |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module the engine is currently disabled or enabled due to the stop-start system. |
| Engine status |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current status of the engine system; off, on, hot or cold. |
| Engine torque output |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current engine torque output. This information is used for the hill start assist function and the various stability assist functions. |
| Gear lever position |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current transmission gear lever position, this is used for the hill start assist system and the Electronic Stability Control (ESC) system. The hill start assist system operates in forward and reverse gears. The Electronic Stability Control (ESC) system does not operate when the transmission is in REVERSE. |
| Hill start assist request |
BCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current, driver selected mode for the hill start assist system; off, auto or manual. |
| Ignition status |
BCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current ignition status; off, accessory, run, start, unknown or invalid. |
| 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 ACC. Over time, the ABS module learns the offset of the sensors inside the RCM. When a new serial number is found and the IVD Initialization procedure is carried out using a scan tool, the ABS module resets the offset number learned for Electronic Stability Control (ESC). |
| Steering angle sensor data |
PSCM |
Several steering angle messages are sent to the ABS module from the PSCM. These messages include steering angle sensor status, steering wheel angle and steering wheel rotation count. The ABS module uses the steering angle sensor data for Electronic Stability Control (ESC) system operation. |
| Transmission in reverse |
PCM |
This message is sent to the GWM and then to the ABS module. This message informs the ABS module when the transmission is in REVERSE, this is used for the hill start assist system and the Electronic Stability Control (ESC) system. The hill start assist system operates in forward and reverse gears. The Electronic Stability Control (ESC) system does not operate when the transmission is in REVERSE. |
| Vehicle configuration data |
BCM |
This message is sent to the GWM and then to the ABS module. This message provides the ABS module with the current optional and configured items such as tire size, axle ratio, manual or automatic transaxle, keyless entry and VIN. |
