Normal Operation
The adaptive front lighting 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 adaptive front lighting module. The adaptive front lighting 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 occupant classification sensor module, the steering angle sensor module (if equipped) and the instrument cluster. Voltage to the adaptive front lighting module is supplied by circuit CBB51 (BN). Ground is supplied by circuit GD120 (BK/GN).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Adaptive front lighting module
