Fog/Driving Lamp: Testing and Inspection

Quick-Checks:
1. If any of the fog lights operate correctly, then fuse #1 (S1) and the fog light relay are OK.
2. If one front fog light operates correctly, then the front fog light switch and the front tog light circuit (up to connector T10) are OK. The fault lies in the light, the bulb or the wiring from T10 to the light.
