Normal Operation
The central junction box (CJB) supplies voltage to the lighting control module (LCM) through circuit 195 (TN/WH). When a request for the parking lamps is detected, the LCM provides voltage to the parking and license plate lamps through circuit 14 (BN). Ground is provided for the parking lamps through circuit 57 (BK).

Possible Causes
- Circuit 14 (BN) short to voltage
- Circuit 1032 (WH/BK) short to ground
- LCM
