Normal Operation
The headlamp switch receives voltage from the smart junction box (SJB) fuse 37 (25A) through circuit 1695 (YE/WH). When the headlamp switch is placed in the headlamps ON position, voltage is routed to the multifunction switch through circuit 15 (RD/YE). The multifunction switch then routes the voltage to the headlamps through the SJB.
Possible Causes
- Fuse
- Circuit 15 (RD/YE) open
- Circuit 1695 (YE/WH) open
- Headlamp switch
- Multifunction switch
- SJB
