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 trouble codes 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 trouble code(s) using MIL or scan tool. See ENTERING ON-BOARD DIAGNOSTICS. If trouble codes are not present and/or scan tool is used, proceed to TEST TC-1A  . Perform indicated VERIFICATION PROCEDURE test after repairs. See SELF-DIAGNOSTIC TESTS DIRECTORY table.
