Diagnostic Symptom Check

If complaint is not "CHECK ENGINE" lamp related, this check will lead to most likely problem area. However, first make checks that would normally be made for the complaint on a vehicle without CCC system.
Follow instructions in diagnostic chart and repair malfunction. After repair, perform FIELD SERVICE MODE CHECK.

NOTE: The FIELD SERVICE MODE CHECK is an integral part of the DIAGNOSTIC CIRCUIT CHECK flow chart. Be sure to start at the beginning of the DIAGNOSTIC CIRCUIT CHECK to ensure that all problems have been diagnosed and repaired before proceeding to the FIELD SERVICE MODE part of the diagnostic chart.
