Section 5 (Engine Controls - Tests W/Codes): Introduction
WARNING: This page is about a different car, the 1997 Ford Aspire. However, it is still accessible from the selected car via links, so may be relevant.
If no faults were found while performing Basic Diagnostic Procedures in the BASIC TESTING article, proceed with self-diagnostics. If no fault codes or only pass codes are present after entering self-diagnostics, proceed to the TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.).
