Symptom Table
System Check
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 a 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 to
General
Troubleshooting Procedures). See: Diagrams/Diagnostic Aids
