This message informs the ABS module of the current cruise control system status: off, denied, standby or active; and the current cruise control mode: not active, keeping speed, accelerating, decelerating, resuming high, resuming low, tap up waiting, tap down waiting. |
| Door ajar status | BCM | This message is sent to the GWM and then to the ABS module. This message informs the ABS module when a door, the hood or the liftgate is opened. The ABS module resets the parameters for ESC, RSC and hill start assist operations. |
| Driver safety belt buckle status | RCM | This message provides the ABS module with the current driver safety belt buckle status; belted, unbelted, faulty or unknown. The ABS module uses the safety belt status for hill start assist operation. |
| Engine torque available | PCM | This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current amount of engine torque reduction available to assist with traction control, ESC and RSC. |
| Engine RPM | PCM | This message is sent to the GWM and then to the ABS module. Used to inform the ABS module of the current engine RPM. The ABS module uses this information for traction control, ESC, RSC and hill start assist operations. |
| 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 engine start-stop status (if equipped); engine off, engine on, engine auto stopped or not used. |
| EPAS status | PSCM | This message informs the ABS module of the current EPAS status; active or inactive. |
| Factory mode | BCM | This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current vehicle life cycle mode; normal, factory, transport or not used. The ABS and stability control features operate differently depending on the current vehicle life cycle. |
| Gear lever position | PCM | This message is sent to the GWM and then to the ABS module. This message informs the ABS module of which gear the driver has selected. This information is used for ESC, RSC and hill start assist operations. |
| Hill descent control request | ATCM | This message informs the ABS module the driver has requested the hill descent control system to be activated or deactivated. |
| Hill start assist mode request | IPC | This message is sent to the GWM and then to the ABS module. This message informs the ABS module the driver has requested the hill start assist system to be activated or deactivated. |
| 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. |
| Odometer master value | IPC | This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current odometer value. |
| Parking brake active | BCM | This message is sent to the GWM and then to the ABS module. This message provides the ABS module with the current parking brake status; applied or not applied. This information is used for hill start assist operation. |
| Power pack status | 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 status; power pack off - torque not available, power pack on - torque not available, start in progress - torque not available or power pack on - torque available. This information is used for the traction control, hill start assist, ESC and RSC feature operation. |
| Reverse gear status | PCM | This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current reverse gear status; inactive not confirmed, inactive confirmed, active not confirmed, active confirmed or fault. This information is used for ESC, RSC and hill start assist operations. |
| RCM serial number | RCM | This message is sent to the GWM and then to the ABS module. The ABS module stores the RCM serial number and verifies the serial number when the vehicle is started or the ignition is set to ON or ACC. Over time, the ABS module learns the offset of the stability sensors inside the RCM. When a new RCM serial number is found and the Interactive Vehicle Dynamics (IVD) Initialization procedure is carried out using a diagnostic scan tool, the ABS module resets the offset values learned for the yaw rate sensor, lateral accelerometer and roll rate sensor. |
| Steering wheel angle | PSCM (vehicles without active park assist) | The ABS module uses steering angle sensor information for ESC and RSC operation. This message provides the ABS module with the current steering wheel angle in degrees as well as the steering wheel angle count (number or revolutions). |
| Steering wheel angle | SCCM (vehicles with active park assist) | The ABS module uses steering angle sensor information for ESC and RSC operation. This message provides the ABS module with the current steering wheel angle in degrees as well as the steering wheel angle count (number or revolutions). |
| Terrain mode request | ATCM | This message informs the ABS module of the current driver requested terrain mode; sand mode, mud ruts mode, rock crawl mode, dynamic mode, undefined, fail-safe default or special operating mode off. The ABS module adjusts the operating parameters of the various stability control systems depending on which terrain mode is selected. |
| 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. |
