Normal Operation

The occupant classification sensor module (OCSM) 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 network connection to the OCSM. The OCSM shares the HS-CAN with the PCM, the ABS module, the 4X4 control module, the instrument cluster (IC), the power steering control module (PSCM) and the restraints control module (RCM). Voltage for the OCSM is provided by circuit (W/L) and circuit (B/W) provides ground.
