Troubleshooting Hints
1. Check Fuse 19 by visual inspection.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 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
