Normal Operation
The HS-CAN uses an unshielded twisted pair cable, circuits VDB04 (WH/BU) and VDB05 (WH). The PCM, the ABS module, the restraints control module (RCM), the occupant classification sensor module, the four wheel drive (4WD) control module (if equipped), the steering angle sensor module (if equipped), the adaptive front lighting module (if equipped) and the instrument cluster all communicate with the scan tool using the HS-CAN.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PCM
- RCM
- ABS module
- Instrument cluster
- Occupant classification sensor
- 4WD control module (if equipped)
- Steering angle sensor module (if equipped)
- Adaptive front lighting module (if equipped)
