Symptom Diagnosis

Symptom checks cannot be used properly unless the problem occurs while the vehicle is being tested. To reduce diagnostic time, ensure basic diagnostic procedures in BASIC TESTING article and self-diagnostics in TESTS W/CODES article were performed before diagnosing a symptom. Symptoms available for diagnosis include:

• Engine Cranking Or Starting Problems
• Engine Idling Problems
• Engine Driveability Problems
• Engine Stalling Problems
