If no faults were found while performing BASIC DIAGNOSTIC PROCEDURES, proceed with self-diagnostics. If no fault codes or only pass codes are present after entering self-diagnostics, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).
CONNECTOR IDENTIFICATION
Harness connector terminal identification illustrations are generic and categorized by the number of terminals. All connector views are from the component side unless otherwise specified. For harness connector terminal identification, see appropriate HARNESS CONNECTOR IDENTIFICATION table.
