Normal Operation
When the headlamp switch is placed in the HEADLAMPS ON position, the multifunction switch routes voltage to the smart junction box (SJB) through circuit CLF18 (BU/WH). The SJB then routes voltage to the LH and RH low beams.

Possible Causes
- Circuit CLF18 (BU/WH) open
- Multifunction switch
- SJB
