ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY
ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY
Description
INFOID:0000000009019639
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:0000000009019640

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 4 – 5 seconds after the selector lever is moved to the “P” position.
Does shift position indicator display “P”?
YES
>> GO TO 5.
NO
>> GO TO 4.
4.
DETECT MALFUNCTIONING 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 1.
NO
>> Repair or replace the malfunctioning parts.
5.
ERASE THE CVT FLUID DEGRADATION LEVEL DATA
With CONSULT
1. Select “WORK SUPPORT” in “TRANSMISSION”.
2. Select “CONFORM CVTF DETERIORTN”.
3. Touch “Clear”.

CALIBRATION OF G SENSOR
CALIBRATION OF G SENSOR
Description
INFOID:0000000009019641
TCM stores calibration data (inherent characteristic value) of G sensor to provide accurate control. Therefore,
it is required to perform calibration of G sensor after the following work is performed.
• Removal/installation or replacement of G sensor
• Replacement of TCM
Procedure
INFOID:0000000009019642
1.
PREPARATION BEFORE CALIBRATION PROCEDURE
1. Park the vehicle on a level surface.
2. Adjust air pressure of all tires to the specified pressure.
