FOREWORD [FW6A-EL]

If there is any vehicle malfunction complaint lodged by a customer, perform malfunction diagnosis according to the troubleshooting procedure.

Automatic Transaxle Control System Troubleshooting Procedure Flow Chart. Scheme 1768

Scheme 1768: Automatic Transaxle Control System Troubleshooting Procedure Flow Chart

Action for Non-repeatable Malfunction

If the malfunction does not recur, verify the malfunction cause by performing the following actions: Verify that no DTCs are stored. (See «ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL]»(ref-579376-S25255133932013100700000) .) Based on the repair order form, attempt to drive the vehicle or perform tests to replicate the malfunction, record the data at that time, and detect the malfunction cause.
If the malfunction does not recur after the above servicing, explain to the customer that the vehicle is normal.
