Pinpoint Test U: The Fog Lamps On Indicator Is Inoperative

Refer to Wiring Diagram Set 86, Fog Lamps for schematic and connector information. Diagrams By Number

Normal Operation

When the Smart Junction Box (SJB) detects the fog lamps on request, the SJB energizes the fog lamp relay (integrated into the SJB). When the fog lamp relay is energized, voltage is routed through 2 output circuits from the SJB. One output is through circuit CLF12 (BN/YE) to the fog lamps and the other output is through 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
