Backup Lamp: Description and Operation

The backup lamps are located in the rear compartment lid applique. The back-up lamps operate when the ignition switch is in the RUN position and the transaxle range selector lever is in REVERSE.

The R/CMPT REL fuse supplies battery voltage at all the times to the coil side and the switched side of the backup relay. When the vehicle is placed in REVERSE, a class 2 signal is sent to the BCM. The BCM then applies a ground through the backup lamp relay coil feed control circuit to the backup lamps relay. This energizes the relay and allows battery voltage to be applied to the backup lamps turning them on. The backup lamps receive a constant ground signal
