Troubleshooting Hints

1. Check BACK Fuse with a fuse tester.
2. Check Backup Lamp bulbs.
3. Check that G400 is clean and tight.
4. If one Backup Lamp is inoperative, check for an open in RED wire between S401 and LH/RH Rear Combination Lamp or an open in BLK wire between S402 and LH/RH Rear Combination Lamp.
5. Before component replacement, check for poor connections at related component and in-line harness connector terminal connections.
