Troubleshooting Hints

1. Check PWR MIRR Fuse. If open, check circuit 1140 for a short to ground.
2. Check that G302 is clean and tight.
- 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 systems operational (under load).
- Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems. Refer to General Troubleshooting Procedures. Diagnostic Aids
- Refer to Doors for door access.
- Refer to mirror switch access.
- Refer to System Diagnosis.
