Normal Operation
The stoplamp switch is supplied voltage through circuit SBB31 (WH/RD) from the battery junction box (BJB). When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB) and the high mounted stoplamp through circuit CLS17 (YE/GY).

Possible Causes
- Fuse
- Circuit CLS17 (YE/GY) open
- Circuit SBB31 (WH/RD) open
- Stoplamp switch
