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 SBP22 (BN/RD) from the smart junction box (SJB). When the brake pedal is applied, the stoplamp switch routes voltage to the SJB through circuit CCB08 (VT/WH) which then supplies voltage to all the stoplamps.

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