Backup Lights Circuit Description
The BACKUP LAMPS Relay in the RH I/P Accessory Wiring Junction Block receives B+ at all the times for the coil side from the DIC/RKE fuse. B+ for the switched side of the relay is supplied from the B/U LAMP fuse. 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 B+ to be applied to the backup lamps turning them on. The backup lamps receive a constant ground signal
