Test H: The Stoplamps Are On Continuously

PINPOINT TEST H: THE STOPLAMPS ARE ON CONTINUOUSLY

H1-H7:

Normal Operation
The stoplamp switch is supplied voltage from the smart junction box (SJB) through circuit 10 (LG/RD). When the brake pedal is applied, the stoplamp switch routes voltage to circuit 810 (RD/LG) back to the SJB. Circuit 810 (RD/LG) is then routed out of the SJB to the brake shift interlock solenoid. The SJB monitors voltage input from the stoplamp switch. When the SJB senses brake pedal application, the SJB sends voltage to the rear lamps. Voltage for the LH and RH stoplamps is supplied through circuits 1363 (WH/RD) and 1365 (GY/LB), respectively. Voltage for the high mounted stoplamp is supplied through circuit 1456 (RD/LB).

Possible Causes
- Circuit 810 (RD/LG) short to voltage
- Circuit 1363 (WH/RD) short to voltage
- Circuit 1365 (GY/LB) short to voltage
- Circuit 1456 (RD/LB) short to voltage
- Stoplamp switch
- Brake shift interlock actuator
- SJB
