Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the multifunction switch routes the voltage to the smart junction box (SJB) through circuit 13 (RD/BK). The SJB then routes the voltage to the LH and RH low beams.

Possible Causes
- Circuit 13 (RD/BK) open
- Multifunction switch
- SJB
