ADDITIONAL SERVICE WHEN REPLACING TCM

Description

INFOID:0000000009267873

Always perform the following items when the TCM is replaced.

LOADING OF 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. After the TCM is

replaced, check that the TCM has correctly loaded the calibration data.

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 "TRANSAXLE ASSEMBLY REPLACEMENT: Special Repair

Requirement".

Work Procedure

INFOID:0000000009267874

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 4.

2.

CHECK AFTER TCM IS REPLACED

1. Shift the selector lever to the P position.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait for a minimum of 20 seconds.

4. Turn ignition switch ON.

5. Check that “P” is displayed on shift position indicator on combination meter.

NOTE:

Displayed approximately 2 seconds after the selector lever is moved to the P position.

Does the shift position indicator display “P”?

YES

>> WORK END

NO

>> GO TO 3.

3.

DETECT MALFUNCTION ITEMS

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.

4.

PERFORM TRANSAXLE ASSEMBLY REPLACEMENT

Perform “TRANSAXLE ASSEMBLY REPLACEMENT: Special Repair Requirement”.

>> Refer to

ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY

ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY

Description

INFOID:0000000009267875

Perform the following work after the transaxle assembly is replaced.

ERASING AND LOADING OF 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.

Work Procedure

INFOID:0000000009267876

1.

INITIALIZE TCM

With CONSULT

1. Set parking brake.

5. While maintaining the conditions below, touch “Start”.

-

Vehicle stop status

-

With engine stopped

-

Selector lever: “R” position

-

Accelerator pedal: Depressed

NOTE:

Select “Start” and complete within approximately 20 seconds.
Is “COMPLETED” displayed?

YES

>> GO TO 2.

NO

>> Turn ignition switch OFF and wait for a minimum of 20 seconds then perform the work again.

2.

CHECK AFTER TCM IS INITIALIZED

With CONSULT

1. Turn ignition switch OFF with the selector lever in “R” position and wait for 20 seconds or more.

2. Turn ignition switch ON with the selector lever in “R” position.

Is the indicated value of “CALIB DATA” equal to the value shown in the table?

YES

>> GO TO 3.

NO

>> GO TO 1.

3.

CHECK LOADING OF CALIBRATION DATA

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

2. Check that “P” is displayed on shift position indicator on combination meter.

NOTE:

Displayed approximately 5 seconds after the selector lever is moved to the “P” position.
