INTERMITTENT PROBLEM INSPECTION PROCEDURE

Sometimes the most difficult case in troubleshooting is when a problem symptom occurs but does not occur
again during testing. An example would be if a problem appears only when the vehicle is cold but has not
appeared when warm. In this case, the technician should thoroughly make out a "CUSTOMER PROBLEM
ANALYSIS SHEET" and recreate (simulate) the environment and condition which occurred when the vehicle
was having the issue.

1. Clear Diagnostic Trouble Code (DTC).

2. Inspect connector connection, and check terminal for poor connections, loose wires, bent, broken or

corroded pins, and then verify that the connectors are always securely fastened.
