Refer to TM-59, "DTC Inspection Priority Chart"
when multiple DTCs are detected, and then determine the
order for performing the diagnosis.
Is any DTC detected?
YES >> GO TO 7.

Reconnect parts or connector after repairing or replacing, and then erase DTC if necessary.
>> GO TO 8.
8.FINAL CHECK
Perform “DTC CONFIRMATION PROCEDURE” again to make sure that the repair is correctly performed.
Check that malfunctions are not reproduced when obtaini ng the malfunction information from the customer,
referring to the symptom inspection result in step 3 or 4.
Is DTC or malfunction symptom reproduced?
YES-1 (DTC is reproduced.)>>GO TO 5.
YES-2 (Malfunction is reproduced.)>>GO TO 6.
NO >> Before delivering the vehicle to the customer, make sure that DTC is erased.
Question sheetINFOID:0000000009464009
DESCRIPTION
There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-
erly, a quick and exact diagnosis can be achieved.
In general, perception of a problem varies depending on individuals.
Ask the customer about his/her concer ns carefully. It is important to
understand the phenomenon or status. To systemize all the informa-
tion for the diagnosis, prepare the question sheet referring to the
question points.
In some cases, multiple conditions that appear simultaneously may
cause a DTC to be detected.
