Fog Lamps

The IP fuse block supplies battery positive voltage to the fog lamp relay switch circuit. The FOG fuse in the IP fuse block supplies battery positive voltage to the fog lamp relay coil. When the fog lamp switch is pressed, the Body Control Module (BCM) fog lamp on input is grounded. The BCM will then energizes the fog lamp relay control circuit. The current flow is now from the fog lamp relay switch to both front fog lamps and to ground.
