Test K: The Stoplamps Are On Continuously

PINPOINT TEST K: THE STOPLAMPS ARE ON CONTINUOUSLY

K1-K4:

K4-K6:

Normal Operation
Under normal operation, when the brake pedal is applied, the stoplamp switch sends a voltage signal to the smart junction box (SJB) through circuit 810 (RD/LG). The SJB then sends voltage to the high mounted stoplamps through circuit 1374 (TN/LB).

The SJB then sends a voltage to the rear stoplamps through:
- Freestyle, Five Hundred: (LH) circuit 1363 (WH/RD) and (RH) circuit 1365 (GY/LB).
- Montego: circuit 1374 (TN/LB).

Possible Causes
- A short to voltage in circuit 810 (RD/LG), 1363 (WH/RD), 1365 (GY/LB) or 1374 (TN/LB)
- Stoplamp switch
- Smart junction box (SJB)
