Circuit/System Description

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

Voltage is applied at all times to the fog lamp relay that is soldered to the Underhood Fuseblock. When the fog lamp switch is placed in the ON position, ground is applied to the body control module (BCM) through the fog lamp switch circuit. The BCM then applies a ground to the front fog lamp relay control circuit. This engages the fog lamp relay and applies voltage through the fog lamp fuse to the front fog lamps.
