Before Using This Section

Before using this section, you should have performed the Diagnostic System Check-Computers and Controls Systems and determined that the following criteria:
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 MIL.

Several of the following symptom procedures call for a careful visual and physical inspection. The visual and physical inspection is very important. The inspection can lead to correcting a problem without further inspection which may save valuable time.
