Backup Lamp: Description and Operation

With the ignition switch in the RUN or START position, battery positive voltage (B+) is applied through the IP fuse block TMNSS Fuse to the park/neutral position (PNP) switch via CKT 139 (PNK). When the gear selector is placed in the REVERSE position, battery positive voltage (B+) is applied to the LH and RH backup lamps via CKT 24 (LT ORN). Since the backup lamps are permanently grounded at G401 via CKT 1250 (BLK), they will remain lit until the gear selector is moved out of the REVERSE position.
