Introduction

The diagnostics presented here are based on the failure condition or symptom being present at the time of diagnosis.

When repairs are required, refer to the proper removal and repair procedure.

Diagnostic procedures change every year. New diagnostic systems may be added; carryover systems may be enhanced. IT IS RECOMMENDED THAT YOU REVIEW ALL OF THESE PROCEDURES TO BECOME FAMILIAR WITH ALL NEW AND CHANGED DIAGNOSTIC PROCEDURES. Diagnostic procedures will cover all the necessary requirements to begin a logical diagnostic path for each repair. If there is a trouble code detected, it will direct you to a specific test. If it is a symptom problem, it will direct you to a system test for more specific instructions or directly to a specific test.
