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 any 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:
- Powertrain Control/Emissions Diagnosis (PC/ED) Information
- TSB Messages
- Wiring Diagrams information
These publications provide the necessary information when diagnosing transaxle concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
