Diagnostic Trouble Code Definitions

NOTE: Only transaxle-related DTCs are listed. For engine-related DTC definitions, see TROUBLE CODE DEFINITIONS article in GENERAL INFORMATION. For engine-related DTC diagnosis, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE. These DTCs pertain to engine performance and must be repaired first, as engine performance and related component signals will affect transaxle operation and diagnosis.
