2006 Chevrolet Uplander FWD V6-3.5L VIN LSECTION Description and Operation
MARKER LAMPS
The PARK/LAMP fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to both the coil and switch sides of the PRK LAMP relay, also located in the I/P fuse block. When the headlamp switch is placed in either the PARK or HEAD position, ground is supplied to the BCM on the park lamp switch ON signal circuit. The BCM then applies a ground to the park lamp relay control circuit. This energizes the relay, applying voltage to all park, tail, marker, and license lamps. The park, tail, marker, and license lamps are also turned ON when the headlamps are commanded ON by the BCM for low light operation.
Ground for the headlamp switch is from G200. Grounds for the various lamps are as follows:
- G100 supplies the right front lamps
- G101 supplies the left front lamps
- G400 supplies the right rear lamps
- G401 supplies the left rear lamps
