Powertrain status	PCM	Provides the ABS module with the current engine status; engine off, engine on or engine auto stopped.
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 RUN or ACC. Over time, the ABS module learns the offset of the sensors inside the RCM. When a new serial number is found when the ABS Calibration procedure is carried out using a diagnostic scan tool, the ABS module resets the offset number learned for ESC and RSC.
