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 feature.
Engine RPM	PCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current engine RPM. This message is used by the ABS module for the hill start assist feature and launch control feature.
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 feature and launch control feature.
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 message is used for operation of the hill start assist feature and the ESC feature. The hill start assist feature operates in forward and reverse gears but the ESC feature does not operate when the transmission is in REVERSE.
Hill start assist mode	IPC	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 feature; off, auto or manual.
Ignition key type	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current ignition key type; MyKey® admin key, MyKey® restricted key, key not programmed - read failure, unknown key type or invalid key type. The ABS module uses the ignition key type for activation and deactivation of certain stability control features.
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.
Launch control 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 launch control feature activation.
Launch control system status	PCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the launch control system status as selected by the driver.
Line lock 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 line lock feature activation.
Park brake status	BCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current parking brake status; applied or released. The ABS module uses this information for the hill start assist feature.
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 operation status; Off - torque not available, On - torque not available, On - torque available or Start in Progress - torque not available. This information is used for the activation and operation of the stability control features.
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 diagnostic scan tool, the ABS module resets the offset number learned for ESC.
Reverse gear selected	PCM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module the driver has requested REVERSE gear and the current status of REVERSE gear; active, inactive or faulted. This message is used for operation of the hill start assist feature and the ESC feature. The hill start assist feature operates in forward and reverse gears but the ESC feature does not operate when the transmission is in REVERSE.
Selectable drive mode	FCIM	This message is sent to the GWM and then to the ABS module. This message informs the ABS module of the current, driver selected vehicle mode; Normal, Sport, Snow-Wet or Track. The ABS module adjusts the thresholds for anti-lock braking and stability control system intervention depending on the mode selected.
Stability-traction control mode	FCIM	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 traction control and stability control features; on, off or sport.
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 ESC feature 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 feature and the ESC feature. The hill start assist feature operates in forward and reverse gears. The ESC feature does not operate when the transmission is in REVERSE.
