Test T: The Parking, Rear or License Lamps Are On Continuously

PINPOINT TEST T: THE PARKING, REAR OR LICENSE LAMPS ARE ON CONTINUOUSLY

Normal Operation
The smart junction box (SJB) sends a reference signal to the multifunction switch through circuit 1032 (WH/BK). When the multifunction switch is switched to the parking lamps ON position, the voltage signal is routed to ground through circuit 570 (BK/WH).

When the SJB detects the multifunction switch in the parking lamps ON position, the SJB provides a ground for the parking lamp relay coil. Voltage to the parking lamp relay is provided internally by the SJB. When the parking lamp relay is energized, voltage is sent through circuit 14 (BN) to the parking and license lamps.

Possible Causes
- circuit 1032 (WH/BK) short to ground
- circuit 14 (BN) short to voltage
- parking lamp relay
- multifunction switch
- SJB
