Test A: Both Headlamps Are Inoperative

PINPOINT TEST A: BOTH HEADLAMPS ARE INOPERATIVE

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).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Headlamp switch
- Multifunction switch
- SJB
