PINPOINT TEST T: THE FOG LAMPS ON INDICATOR IS INOPERATIVE

T1:

T1-T3:

Normal Operation
When the smart junction box (SJB) detects the fog lamps on request, the SJB provides ground to the fog lamp relay coil (integral to the SJB). When the fog lamp relay is energized, voltage is routed through circuit CLF21 (GY/VT) to the fog lamps and to circuit CLF28 (BN/WH) to the headlamp switch for the fog lamps on indicator.

Possible Causes
- Circuit CLF28 (BN/WH) open
- Headlamp switch
- SJB
