Test C: The High Beams Are Inoperative

PINPOINT TEST C: THE HIGH BEAMS ARE INOPERATIVE

C1-C2:

C2-C4:

Normal Operation
When the headlamp switch is placed in the headlamps ON position, voltage is routed to the multifunction switch through circuit 15 (RD/YE). When the multifunction switch is in the high beam position, the multifunction switch then routes the voltage to the smart junction box (SJB) through circuit 1709 (BN). The SJB then routes the voltage to the high beam headlamps through circuit 12 (LG/BK).

Possible Causes
- Fuse
- Circuit 12 (LG/BK) open
- Circuit 1709 (BN) open
- Multifunction switch
- SJB
