Tests W/Codes: Introduction
If no faults were found while performing testing in BASIC TESTING article, proceed with self-diagnostics. If no fault codes or only pass codes are present, proceed to TESTS W/O CODES article for diagnosis by symptom (i.e. ROUGH IDLE, NO-START, etc.).
NOTE:
All voltage tests should be performed with a Digital Volt Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated different in testing procedures.
