Normal Operation
The smart junction box (SJB) provides voltage to the multifunction switch and the headlamp switch through circuit SBP23 (WH/RD). When the headlamp switch is placed in the HEADLAMPS ON position, the voltage is routed to the multifunction switch through circuit CLS24 (BN/WH).

Possible Causes
- Fuse
- Circuit CLS24 (BN/WH) open
- Circuit SBP23 (WH/RD) open
- Headlamp switch
- Multifunction switch
- SJB
