PINPOINT TEST T: THE FOG LAMPS ARE ON CONTINUOUSLY

Normal Operation
When the parking lamps are on, voltage is routed to the headlamp switch through circuit 14 (BN). When the fog lamp switch is engaged, voltage is routed to the fog lamp relay coil, which is integral to the central junction box (CJB), through circuit 275 (YE). The fog lamp relay coil is grounded through circuit 57 (BK). The fog lamp relay voltage supply is received from CJB fuse 43 (10A). When the fog lamp relay is energized, voltage is routed to the fog lamps through circuit 478 (TN/OG).

Possible Causes
- Circuit 14 (BN) short to voltage
- Circuit 275 (YE) short to voltage
- Circuit 478 (TN/OG) short to voltage
- Headlamp switch
- CJB
