Troubleshooting an electronically controlled automatic transaxle is simplified by using the proven method of diagnosis. One of the most important things to remember is that there is a definite procedure to follow.
NOTE:
Do not take shortcuts or assume that critical checks or adjustments have already been made.
Follow the procedures as written to avoid missing critical components or steps.
To correctly diagnose a concern, have the following publications available:
- AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS .
- Introduction - Gasoline Engines article.
- OASIS Messages.
- Technical Service Bulletins (TSBs).
- SYSTEM WIRING DIAGRAMS article.
These publications provide the information required when diagnosing transaxle concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated. Refer to Diagnostic Flow Chart .
