Normal Operation
The occupant classification sensor module communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits VDB04 (WH/BU) (HS-CAN +) and VDB05 (WH) (HS-CAN -) provide the network connection to the occupant classification sensor module. The occupant classification sensor module shares the HS-CAN network with the PCM, the ABS module, the four wheel drive (4WD) control module (if equipped), the restraints control module (RCM), the adaptive front lighting module (if equipped), the steering angle sensor module (if equipped) and the instrument cluster. Voltage to the occupant classification sensor module is supplied by circuit CBP46 (WH/BU). Ground is supplied by circuit GD143 (BK/VT).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Occupant classification sensor module
