Normal Operation
The smart junction box (SJB) provides voltage to the headlamp switch through circuit 276 (BN). When the headlamp switch is placed in the parking lamps ON position, the headlamp switch routes the voltage to the SJB through circuit 14 (BN). The SJB then routes the voltage to the front and rear lamps through circuit 14 (BN).

Possible Causes
- Fuse
- Circuit 14 (BN) open
- Circuit 276 (BN) open
- Headlamp switch
- SJB
