Pinpoint Test 4: The Fog Lamps On Indicator Is Inoperative

PINPOINT TEST 4: 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 (BR/Y) to the fog lamps and through circuit (BR/W) to the headlight switch for the fog lamps on indicator.

Possible Causes

- Wiring, terminals or connectors
- Headlight switch
- SJB

Diagnostic Procedure

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
