INFOID:0000000010589257

NOTE:
“DTC” includes DTC at the 1st trip. 

1.

OBTAIN INFORMATION ABOUT SYMPTOM

Refer to 

TM-278, "Diagnostic Work Sheet"

 and interview the customer to obtain the malfunction information

(conditions and environment when the malfunction occurred) as much as possible when the customer brings
in the vehicle.

>> GO TO 2.

2.

CHECK DTC

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. 

TM-

373, "Symptom Table"

 can be used effectively.

3.

Check the relevant information including STI, etc. 

Do malfunction information and DTC exists?

Malfunction information and DTC exists.>>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 

TM-263, "Fail-safe"

.

Interview sheet can be used effectively when reproduce malfunction conditions. Refer to 

TM-278, "Diagnostic

Work Sheet"

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-266, "DTC Inspection Priority Chart"

 when multiple DTCs are detected, and then determine the

order for performing the diagnosis.
Is any DTC detected?

 from the symptom inspection result in step 4. Then identify where to start per-

forming the diagnosis based on possible causes and symptoms.

>> GO TO 8.

7.

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.

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.

Diagnostic Work Sheet

INFOID:0000000010589258

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 TRANSAXLE ASSEMBLY

Description

INFOID:0000000010589261

Perform the following work after the transaxle assembly is replaced.

WRITING TCM DATA

• TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this

reason, after replacing transaxle assembly, it is necessary to write new data in TCM.

ERASING OF CVT FLUID DEGRADATION LEVEL DATA 

• TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if

the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by
TCM.

1.

Turn ON the ignition switch with the shift selector at the “P” position. 

2.

Press the shift selector button with the brake pedal depressed, and confirm that the shift selector can be
moved to positions other than “P”. Also confirm that movement is not allowed from the “P” position to other
position without depressing the brake pedal. 

3.

Move the shift selector and check for “excessive effort”, “sticking”, “noise” or “rattle”.

4.

Confirm that shift selector stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the shift selector is in matches the position shown
by the transaxle body.

5.

Make sure that the shift selector is moved to all the shift posi-
tions in the manner shown.

6.

When the shift selector button is pressed without applying for-
ward/backward force to the shift selector at “P”, “R”, “N”, or “D”
positions, there should be no “sticking” on the shift selector but-
ton operation. 

7.

The relationship between selector lever, engine starting ability,
and shift position indicator lighting should satisfy the conditions
of the following table.

8.

Confirm that the back-up lamps illuminate only when lever is placed in the “R” position. Confirm that the
back-up lamps does not illuminate when selector lever is pushed against “R” position in the “P” or “N”
position.

9.

Check that the transaxle is locked when the selector lever is in the “P” position.

10. When selector lever is set to manual shift gate, make sure that manual mode is displayed on combination

meter. Shift selector lever to “+” and “

−

” sides, and check that set shift position changes.

Adjustment

INFOID:0000000010589267

1.

Shift the selector lever to the “P” position.

CAUTION:

Rotate the wheels at least a quarter turn and be certain the Park position mechanism is fully
engaged.

2.
