Diagnostic Strategy: Notes

Diagnosis and testing 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 information available:

SELF-DIAGNOSTICS
Technical Service Bulletins (TSBs)
SYSTEM WIRING DIAGRAMS

This information is required when diagnosing transaxle concerns.

Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
