Test J: The Stoplamps Are On Continuously

PINPOINT TEST J: THE STOPLAMPS ARE ON CONTINUOUSLY

J1-J8:

J9-J12:

Normal Operation - All Vehicles
When the brake pedal is applied, the stoplamp switch routes voltage to the smart junction box (SJB) through circuit CCB08 (VT/WH). The voltage is then routed out of the SJB to the high mounted stoplamp through circuit CCB08 (VT/WH).

Normal Operation - Explorer
When the SJB detects the brake pedal applied, the SJB provides voltage to the LH and RH rear stoplamps through circuit CLS18 (GY/BN) and circuit CLS19 (VT/OG) respectively.

Normal Operation - Mountaineer
When the SJB detects the brake pedal applied, the SJB provides voltage to the LH and RH rear stoplamps through circuit CLS44 (VT/BN).

Possible Causes
- Circuit CCB08 (VT/WH) short to voltage
- Circuit CLS18 (GY/BN) short to voltage
- Circuit CLS19 (VT/OG) short to voltage
- Circuit CLS44 (VT/BN) short to voltage
- Stoplamp switch
- Brake shift interlock actuator
- Trailer brake control module
- SJB
- Four-wheel drive (4WD) control module
- Anti-lock brake system (ABS) module
