Diagnostic Strategy: Notes
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 short cuts 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:
- Introduction - Gasoline Engines article
- OASIS Messages
- Technical Service Bulletins (TSBs)
- SYSTEM WIRING DIAGRAMS (Five Hundred), SYSTEM WIRING DIAGRAMS (Freestyle) or SYSTEM WIRING DIAGRAMS (Montego)
This information is required when diagnosing transaxle concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
