Diagnostic Procedure

NOTE: DO NOT  skip any steps in self-diagnostic tests or incorrect diagnosis may result. Ensure self-diagnostic tests apply to engine being tested.

If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. Always perform a visual inspection before attempting to diagnose engine control system problems. See VISUAL INSPECTION  . Enter on-board diagnostics, and retrieve fault code(s) using CHECK ENGINE light or retrieve fault messages using DRB-II. See ENTERING ON-BOARD DIAGNOSTICS. If faults are not present and/or DRB-II (Diagnostic Readout Box-II) is used, proceed to TEST FC-1A. Perform indicated VERIFICATION PROCEDURE test after repairs. See SELF-DIAGNOSTIC TESTS DIRECTORY table.
