Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS
1. Check PWR DR LK Fuse and INT LP Fuse in RH Rear Junction Block.
2. Before component replacement, check for poor terminal contact at component and harness connectors.
3. Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
4. Check for a broken (or partially broken) wire inside of insulation which could cause system malfunction but prove good in a continuity/voltage check with a system disconnected. (See Troubleshooting Procedures.) Diagnostic Aids
