Test H: All The Stoplamps Are Inoperative

PINPOINT TEST H: ALL THE STOPLAMPS ARE INOPERATIVE

Normal Operation
The stoplamp switch is supplied voltage through circuit SBP02 (YE/RD) from the smart junction box (SJB). When the brake pedal is applied, the stoplamp switch routes voltage back to the smart junction box (SJB) and the high mounted stoplamp through circuit CCB08 (VT/WH). The SJB provides voltage to the rear lamps when it receives input from the stoplamp switch indicating that the brake pedal is applied.

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