Normal Operation
When the brake pedal is applied, the stoplamp switch allows voltage to flow through circuit 511 (LG). Circuit 511 (LG) provides voltage to the high mounted stoplamp and the smart junction box (SJB). The SJB then provides voltage to the LH and RH rear lamps through circuits 22 (LB/BK) and 810 (RD/LG), respectively.

Possible Causes
- Circuit 22 (LB/BK) short to voltage
- Circuit 511 (LG) short to voltage
- Circuit 810 (RD/LG) short to voltage
- Stoplamp switch
- Speed control module
- SJB
- PCM
- ABS module
