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.

4. Repair or replace the component that has a problem.  

5. Verify that the problem has disappeared with the road test.
