Troubleshooting Hints

1. Check R/CMPT REL Fuse by visual inspection.
2. Check the Backup Lamps for damage to the filament or corrosion between the bulb and the lamp socket.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with the system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (refer ti General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis. Flow of Diagnosis
