Backup Lamp: Description and Operation

Vehicles equipped with an automatic transmission, the BU LMP fuse in the IP fuse block supplies battery positive voltage to the park/neutral position switch. Vehicles equipped with a manual transmission, the BU LMP fuse in the P fuse block supplies battery positive voltage to the backup lamps switch. When the driver places the gear selector lever in the REVERSE position, the current flow is from the park/neutral position switch or the backup lamps switch, to the back up lamps. The backup lamps are grounded at G401 and G402.
