Troubleshooting Hints

1. Check CTSY Fuse by noting normal operation of the courtesy lamps.
2. Check that G200 is clean and tight. If equipped with Power Door Locks, check G200 by noting normal operation of the Power Door Locks.
^ 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). Diagnostic Aids
^ Refer to System Diagnosis.
