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

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.

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

2. Turn ignition switch ON with the selector lever in “R” position.
CAUTION:
Never start the engine.
3. Select “CALIB DATA” in “TRANSMISSION”.
