Troubleshooting Hints

1. Check CTSY Fuse. If CTSY Fuse is open, check for a short to ground in CKT 240.
2. Check that grounds G119, G203 and G302 are clean and tight.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
