Normal Operation

The restraints control module (RCM) communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits (W/L) (HS-CAN +) and (W) (HS-CAN -) provide the HS-CAN connection to the RCM. The RCM shares the HS-CAN network with the PCM, the ABS module, the 4X4 control module, the instrument cluster (IC), the power steering control module (PSCM) and the occupant classification sensor module (OCSM). Voltage for the RCM is provided by circuits (G/V) and the RCM is case grounded.
