Backup Lamps (Export)

WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

The T/SIG fuse supplies ignition voltage to the backup relay switch contacts. The B/U LAMP fuse in the junction block - underhood, supplies battery positive voltage to the transmission range switch. When the driver places the gear selector lever in the REVERSE position, the transmission range switch closes and the current flow is through to the backup relay coil, energizing the relay. When the backup relay is energized the right and left backup lamps receive voltage through the back up lamp supply voltage circuit. The backup lamps are permanently grounded through to G401.
