and interview the customer to obtain the malfunction information (condi-
tions and environment when the malfunction occurred) as much as possible when the customer brings in the
vehicle.
>> GO TO 2.
2.

1. Before checking the malfunction, check whether any DTC exists.
2. If DTC exists, perform the following operations.
-
Records the DTCs. (Print out using CONSULT and affix to the Work Order Sheet.)
-
Erase DTCs.
-
Check the relation between the cause found by DTC and the malfunction information from customer.
can be used effectively.
3. Check the relevant information including STI, etc.
Do malfunction information and DTC exist?
Malfunction information and DTC exist.>>GO TO 3.
Malfunction information exists but no DTC.>>GO TO 4.
No malfunction information, but DTC exists.>>GO TO 5.
3.
REPRODUCE MALFUCTION SYSTEM
Check the malfunction described by the customer on the vehicle.
Check if the behavior is fail safe or normal operation. Refer to
.
Interview sheet can be used effectively when reproduce malfunction conditions. Refer to
.
Verify the relationship between the symptom and the conditions in which the malfunction described by the cus-
tomer occurs.
>> GO TO 5.
4.
REPRODUCE MALFUNCTION SYMPTOM
Check the malfunction described by the customer on the vehicle.
Check if the behavior is fail safe or normal operation. Refer to
.
Interview sheet can be used effectively when reproduce malfunction conditions.
.
Verify the relationship between the symptom and the conditions in which the malfunction described by the cus-
tomer occurs.
>> GO TO 6.
5.
PERFORM “DTC CONFIRMATION PROCEDURE”
Perform “DTC CONFIRMATION PROCEDURE” of the appropriate DTC to check if DTC is detected again.
Refer to
TM-111, "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.
NO
>> Follow
GI-41, "Intermittent Incident"
to check.

REPAIR OR REPLACE THE MALFUNCTIONING PARTS
Repair or replace the detected malfunctioning parts.
Reconnect parts or connector after repairing or replacing, and then erase DTC if necessary.
>> GO TO 8.

FINAL CHECK
Perform “DTC CONFIRMATION PROCEDURE” again to make sure that the repair is correctly performed.
Check that malfunctions are not reproduced when obtaining 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 sheet
INFOID:0000000009019636
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
cause a DTC to be detected.

ADDITIONAL SERVICE WHEN REPLACING TCM
Description
INFOID:0000000009019637
When replacing the TCM, perform the following work.
CHECK LOADING 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 TCM has correctly loaded the calibration data.
CALIBRATION OF G SENSOR
• TCM stores calibration data (inherent characteristic value) of G sensor to provide accurate control. There-
fore, it is required to perform calibration of G sensor after the replacement of TCM.
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” after “G sensor calibration”.
Procedure
INFOID:0000000009019638
1.
CHECK WORK CONTENTS
Replacing only the TCM>>GO TO 2.
Replacing the TCM after the transaxle assembly is replaced>>GO TO 2.
Replacing the transaxle assembly after the TCM is replaced>>GO TO 5.
2.
LOADING OF CALIBRATION DATA
1. Shift the selector lever to the “P” position.
2. Turn ignition switch ON.
3. Check that “P” is displayed on shift position indicator on combination meter.
NOTE:
Displayed approximately 4 – 5 seconds after the selector lever is moved to the “P” position.
Does the shift position indicator display “P”?
YES
>> GO TO 3.
NO
>> GO TO 4.
3.
PERFORM G SENSOR CALIBRATION
>> WORK END
4.
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 2.
NO
>> Repair or replace the malfunctioning parts.
5.
PERFORM G SENSOR CALIBRATION
>> Perform “ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY” after “CALI-
BRATION OF G SENSOR”. Refer to
