Description

INFOID:0000000009948909

When replacing the transaxle assembly, perform the following work.

ERASING, 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. For this reason,
after the transaxle assembly/control valve is replaced, it is necessary to erase the calibration data previously
stored in TCM, to load new calibration data, and to stored them.

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/control valve is replaced, it is necessary to erase the CVT fluid degradation level
data recorded by TCM. 

Procedure

INFOID:0000000009948910

CAUTION:

Immediately after TCM is replaced or after transaxle assembly is replaced (after TCM initialization is
complete), self-diagnosis result of “P1701”, “P1709” may be displayed. In this case, erase self-diagno-
sis result using CONSULT. After erasing self-diagnosis result, perform DTC P1701, P1709 reproduction
procedure and check that malfunction is not detected. Refer to 

TM-144, "DTC Logic"

 (P1701), 

TM-148,

"DTC Logic"

 (P1709).

1.

PREPARATION BEFORE WORK

With CONSULT

1.

Start the engine.

CAUTION:

Never drive the vehicle.

2.

Select “Data Monitor” in “TRANSMISSION”.

3.

Select “ATFTEMP COUNT”.

 Is “ATFTEMP COUNT” 47 [equivalent to 20

°

C (68

°

F)] or more?

YES

>> GO TO 2.

NO

>> 1.

Warm up the transaxle assembly until “ATFTEMP COUNT” reaches “47” [equivalent to 20

°

C

(68

°

F)] or more.

2.

GO TO 2.

2.

PERFORM TCM INITIALIZATION

With CONSULT

1.

Turn ignition switch OFF.

2.

Turn ignition switch ON.

CAUTION:

Never start the engine.

3.

Select “Self Diagnostic Results” in “TRANSMISSION”.

4.

Shift selector lever to “R” position.

5.

Depress slightly the accelerator pedal (Pedal angle: 2.0/8) while depressing the brake pedal.

6.

Select “Erase” with step 5.

7.

Release brake pedal and accelerator pedal.

8.

Turn ignition switch OFF while keeping the selector lever in “R” position.

9.

Wait approximately 10 seconds.

10. Turn ignition switch ON while keeping the selector lever in “R” position.
11. Select “CALIB DATA” in “TRANSMISSION”.
12. Check that “CALIB DATA” value is as shown as in the following table.

Is “CALIB DATA” value it?

YES

>> GO TO 3.

NO

>> GO TO 1.

3.

LOAD CALIBRATION DATA

1.

Shift selector lever to “P” position.

2.

Check that “P” is displayed on shift position indicator on combination meter.
NOTE:
It indicates approximately 1 – 2 seconds after shifting the selector lever to “P” position.

Does shift position indicator display “P”?

YES

>> GO TO 5.

NO

>> GO TO 4.

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
• Power supply and ground of TCM. (Refer to 

TM-144, "Diagnosis Procedure"

.)

Is the inspection result normal?

YES

>> GO TO 1.

NO

>> Repair or replace the malfunctioning parts.

5.

STORE CALIBRATION DATA

1.

Turn ignition switch OFF and wait for 5 seconds.

2.

Turn ignition switch ON.

Does the shift position indicator display “P” at the same time when turning ON the ignition switch?

YES

>> GO TO 6.

NO

>> Check harness between battery and TCM harness connector terminal. Refer to 

TM-144, "Diagno-

sis Procedure"

.

6.

ERASE CVT FLUID DEGRADATION LEVEL DATA

With CONSULT

1.

Select “WORK SUPPORT” in “TRANSMISSION”.

2.

Select “CONFORM CVTF DETERIORTN”.

3.

Touch “Clear”.
