Diagnostic Strategy





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.

Preliminary Inspection

- Verify the concern by operating the vehicle.

- Check the transmission fluid levels and condition.

- Check selector lever linkages for correct adjustment.

Diagnostics

- Carry out On-Board Diagnostic (OBD) procedures Key ON Engine OFF (KOEO) and Key ON Engine Running (KOER).

- Record all DTCs.

- Repair all non-transaxle DTCs first.

- Repair all transaxle DTCs second.

- Erase all continuous DTCs and attempt to repeat them.

- Repair all continuous DTCs.

- If only pass DTCs are obtained, proceed to the Diagnosis by Symptom Index. Refer to Diagnosis By Symptom Diagnosis By Symptom for further information and diagnosis.

Follow the diagnostic sequence to diagnose and repair the concern the first time.
