Self-Diagnostic System: Summary

WARNING: This page is about a different car, the 2003 Saturn Vue and 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

If no hard DTCs are present, and driveability symptoms or intermittent DTCs exist, attempt diagnosis by symptom, or by testing individual components related to system fault. See TROUBLE SHOOTING  . If no problem is found, verify proper electronic control system circuit operation.

NOTE: Always clear DTCs once repairs are complete. See CLEARING DIAGNOSTIC TROUBLE CODES  . Road test vehicle and retrieve DTCs to determine if complaint or DTC is repaired.
