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. When the parking lamp relay is energized, voltage is sent through circuit 14 (BN) to the parking and license lamps. Ground is provided to the parking and license lamps through circuit 57 (BK).
Possible Causes
- circuit 14 (BN) open
- circuit 57 (BK) open
- SJB
