Fog/Driving Lamp: Testing and Inspection

LIGHTING SYSTEM DIAGNOSIS

When the front fog light switch is turned to ON with the tail light or the headlight on (the tail light switch or the headlight switch is ON), the fog light relay turns on, and the fog lights will illuminate.

If the tail lights or the headlights are turned off with the lighting switch OFF while the fog lights are on, the front fog lights turn off at the same time to prevent unattended operation.

If the tail lights are turned off by the headlight automatic shutdown function, the fog lights turn off at the same time. However, if the tail lights illuminate again, the fog lights do not. The front fog lights are controlled by the Smart Wiring System (SWS). For troubleshooting, refer to SWS Diagnosis. Initial Inspection and Diagnostic Overview
