Test T: The Fog Lamps On Indicator Is Inoperative

PINPOINT TEST T: THE FOG LAMPS ON INDICATOR IS INOPERATIVE

Normal Operation
When the smart junction box (SJB) detects the fog lamps on request, the SJB provides ground to the fog lamp relay coil (integrated into the SJB). When the fog lamp relay is energized, voltage is routed through circuit CLF12 (BN/YE) to the fog lamps, and on a separate output, circuit CLF12 (BN/YE) to the headlamp switch for the fog lamps on indicator.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Headlamp switch
- SJB
