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 with the powertrain control module (PCM), the transmission control module (TCM) (if equipped), the anti-lock brake system (ABS) module, the restraints control module (RCM), the four wheel drive (4WD) control module (if equipped) and the instrument cluster. Voltage to the occupant classification sensor module is supplied by circuit CBP17 (BN/GN). Ground is supplied by circuit GD145 (BK/BU).

Possible Causes
- Fuse
- Circuit CBP17 (BN/GN) open
- Circuit GD145 (BK/BU) open
- Circuit VDB04 (WH/BU) open (HS-CAN +)
- Circuit VDB05 (WH) open (HS-CAN -)
- Occupant classification sensor module
