Preliminary Inspection

Verify customer's complaint. Before performing any testing, perform a visual inspection. Check coolant level and condition. Check system fuses. Check connectors for loose, damaged or corroded terminals. Check for damaged wiring harnesses. Check for damaged or binding actuator cable. If area of fault cannot be located or repaired during preliminary inspection, check self-diagnostic system. See SELF-DIAGNOSTIC SYSTEM . Repair as necessary.

If no problem is found, attempt diagnosis by symptom. See SYMPTOM DIAGNOSIS .
