A Important Preliminary Checks

Before using this section, you should have performed the On-Board Diagnostic System Check and determined that:
1. The Control Module and the Malfunction Indicator Lamp (MIL) are operating correctly.
2. There are no Diagnostic Trouble Codes (DTCs) stored, or a DTC exists but without a MIL.
Several of the following symptom procedures call for a careful visual and physical check. The visual and physical checks are very important. The checks can lead to correcting a problem without further checks which may save valuable time.

Perform a visual check to locate the cause of the problem.
^ Refer to Symptoms.
^ The fault must be present to locate the problem. If a fault is intermittent, the use of DTC Tables may result in the replacement of good parts.
