Self-Diagnostic System: Notes

NOTE: The first step in diagnosing any driveability problem is verifying the customer's complaint with a test drive under the conditions the problem reportedly occurred. Before entering self-diagnostics, perform a careful and complete visual inspection. Most transaxle control problems result from mechanical breakdowns or poor electrical connections.

NOTE: In addition to transaxle-related DTCs, engine-related DTCs may be output during RETRIEVING DIAGNOSTIC TROUBLE CODES (QUICK TEST) procedure. These DTCs pertain to engine performance and must be repaired first as engine performance will greatly affect transaxle operation. For information and testing procedures of engine-related DTCs and components, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
