PINPOINT TEST H: THE STOPLAMPS ARE ON CONTINUOUSLY

Normal Operation
When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB) through circuit 511 (LG). Voltage is also routed to the powertrain control module (PCM) through circuit 599 (PK/LG). The SJB then provides voltage to the stoplamps through circuits 1783 (RD/WH), 1374 (TN/LB), 1728 (LB/OG), and 1363 (WH/RD). Ground for the stoplamps is provided through circuit 1205 (BK).

Possible Causes
- Circuit 511 (LG) short to voltage
- Circuit 599 (PK/LG) short to voltage
- Circuit 1363 (WH/RD) 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
- SJB
- PCM
