Troubleshooting Hints

1. Check the R/CMPT REL Fuse for an open. If the fuse is blown check circuit 840 for a short to ground.
2. Check that G402 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 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.
