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 concerns 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

ADDITIONAL SERVICE WHEN REPLACING TCM
Description
INFOID:0000000009650110
When replacing the TCM, perform the following work.
LOADING AND STORING OF CALIBRATION DATA
• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the
ROM assembly (in the control valve). This enables the TCM to perform accurate control. After the TCM is
replaced, check that the calibration data is correctly loaded and stored.
CAUTION:
When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then
replace TCM.
If the TCM is replaced in advance, perform “ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE
ASSEMBLY”. Refer to
Procedure
INFOID:0000000009650111
CAUTION:
Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM
initialization is complete), self-diagnosis result of “P1701”, “P1709” may be displayed. In this case,
erase self-diagnosis result using CONSULT. After erasing self-diagnosis result, perform DTC P1701,
P1709 reproduction procedure and check that malfunction is not detected. Refer to
1.

Does the shift position indicator display “P”?
YES
>> GO TO 3.
NO

2.
DETECT MALFUNCTIONING ITEM
Check the following items:
• Harness between the TCM and the ROM assembly inside the transaxle assembly is open or shorted.
• Disconnected, loose, bent, collapsed, or otherwise abnormal connector housing terminals
Is the inspection result normal?
YES
>> GO TO 1.
NO
>> Repair or replace the malfunctioning parts.
3.
