C4-C5:
Normal Operation
When the multifunction switch is placed in the HIGH BEAM position with the headlamps on, the multifunction switch routes voltage to the smart junction box (SJB) through circuit 632 (GY/OG). The SJB then routes voltage to the high beams through circuit 12 (LG/BK).
Possible Causes
- Fuse
- Circuit 632 (GY/OG) open
- Circuit 12 (LG/BK) open
- Multifunction switch
- SJB
