Circuit/System Verification

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.

Engine running, command the Backup Lamps ON and OFF with a scan tool. The E5A backup lamp-left and the E5B backup lamp-right should turn ON and OFF when changing between the commanded states.

If the E5A backup lamp-left or the E5B backup lamp-right is always OFF, inspect for a burned out bulb or corrosion of the bulb sockets.

If the E5A backup lamp-left and the E5B backup lamp-right are always OFF or always ON, perform the Circuit/System Testing.
