Diagnostic Tests: Notes

NOTE: The following diagnostic tests assume the presence of current (hard) DTCs, or the ability to duplicate DTCs under conditions described in DTC confirmation tests, overall function tests, or during a test drive under same conditions stored in freeze frame data. See TESTING PROCEDURE under SELF-DIAGNOSTIC SYSTEM in SELF-DIAGNOSTICS - INTRODUCTION article. If DTC cannot be duplicated, proceed to TESTS W/O CODES article for diagnosis by symptom.

NOTE: To aid in diagnostics refer to illustrations for ECM harness connector location and terminal identification. See Figure and Figure . Also see appropriate wiring diagram in WIRING DIAGRAMS article.
