ADDITIONAL SERVICE WHEN REPLACING TCM

ADDITIONAL SERVICE WHEN REPLACING TCM

Description

INFOID:0000000009019886

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:0000000009019887

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

Refer to

TM-129, "Procedure"

.

>> 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

Refer to

TM-129, "Procedure"

.

>> Perform “ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY” after “CALI-

BRATION OF G SENSOR”. Refer to

TM-127, "Procedure"

ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY

Description

INFOID:0000000009019888

When replacing the transaxle, perform the following work.

ERASING THE 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 is replaced, it is necessary to erase the calibration data that is stored in the

TCM and load new calibration data.

ERASING THE LEARNED VALUE DATA

• TCM learns indicated pressure for appropriate control of the transaxle assembly and records the learned

values. For this reason, the leaned values stored in TCM must be erased after replacing a transaxle assem-

bly.

ERASING 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.

Procedure

INFOID:0000000009019889
