ADDITIONAL SERVICE WHEN REPLACING TCM

Description

INFOID:0000000010113228

When replacing the TCM, perform the following work.

TCM PROGRAMMING

• Since vehicle specifications are not yet written in a new TCM, it is necessary to write them with CONSULT.

CAUTION:

When replacing TCM, save TCM data on CONSULT before removing TCM.

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 

TM-10, "Description"

.

Procedure

INFOID:0000000010113229

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

reproduction procedure and check that malfunction is not detected. Refer to 

TM-95, "DTC Logic"

(P1701), 

TM-99, "DTC Logic"

 (P1709).

1.

CHECK TCM PART NUMBER

Check TCM part number to see whether it is blank TCM or not.

NOTE:

• Part number of blank TCM is 310F6-XXXXX.

• Check the part number when ordering TCM or with the one included in the label on the container box.
Is the TCM a blank TCM?

YES

>> GO TO 2.

NO

>> GO TO 3.

2.

SAVING TCM DATA

With CONSULT

1. Turn ignition switch OFF.

2. Turn ignition switch ON.

3. Select “Re/programming, Configuration”.

4. Select “AT/CVT”.

NOTE:

If “AT/CVT” is not displayed and TCM data cannot be saved on CONSULT, GO TO 3.

5. Select “Programming”.

6. Save TCM data on CONSULT according to the CONSULT display.

>> GO TO 3.

3.

REPLACE TCM

Replace TCM. Refer to 

TM-168, "Removal and Installation"

.

>> GO TO 4.

4.

LOAD CALIBRATION DATA

1. Shift the selector lever to the “P” position.

2. Turn ignition switch ON.

5.

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 4.

NO

>> Repair or replace the malfunctioning parts.

6.

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-1 (TCM is blank)>>GO TO 7.

YES-2 (TCM is not blank)>>WORK END

NO

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

ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY

ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY

Description

INFOID:0000000010113230

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:0000000010113231

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 reproduction proce-

dure and check that malfunction is not detected. Refer to 

TM-95, "DTC Logic"

 (P1701), 

TM-99, "DTC

Logic"

 (P1709).
