Troubleshooting Hints

1. Check TRUNK REL Fuse or IGN Fuse by visual inspection.
2. Check the Backup Lamps for damage to the filament or corrosion between the Backup Lamp and Backup Lamp Socket.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
