Normal Operation - Freestyle and Five Hundred
When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB), the anti-lock brake system (ABS) module and the brake shift interlock solenoid (internal to the floor shifter, also called the selector lever) through circuit 810 (RD/LG). The SJB then sends voltage through circuits 1363 (WH/RD), 1365 (GY/LB) and 1374 (TN/LB) to the LH stoplamp, the RH stoplamp and the high mounted stoplamp, respectively.

Possible Causes
- Circuit 810 (RD/LG) short to voltage
- Circuit 1363 (WH/RD) short to voltage
- Circuit 1365 (GY/LB) short to voltage
- Circuit 1374 (TN/LB) short to voltage
- Circuit 1728 (LB/OG) short to voltage
- Circuit 1783 (RD/WH) short to voltage
- Stoplamp switch
- Selector lever
- Anti-lock brake system (ABS) module
- SJB
