Clearance Lamp: Description and Operation
CLEARANCE LAMPS
The clearance lamps, are turned on when the headlamp switch is placed in the PARK or HEAD position or anytime the headlamps are requested. The
underhood fuse block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control
module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on the BCM energizes the park
lamp relay.
