Additional Service When Replacing TCM: Description

Always perform the following items when the TCM is replaced. For work procedure, refer to Work Procedure .

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 simultaneously, replace transaxle assembly first and then replace TCM.
