Description

caution

When replacing the TCM, always replace it with a new one. The functions controlled by the TCM does not operate properly in case of reuse of the TCM from another vehicle.

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

WORK BEFORE TCM REPLACEMENT

Calibration data (IP characteristics value) saving

note	TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, it is necessary to save data of current TCM in M.U.T.-III SE before replacing the TCM. After this, the saved data must be written in new TCM.

WORK AFTER TCM REPLACEMENT

TCM programming
note Since vehicle specifications are not yet written in a new TCM, it is necessary to write them with M.U.T.-III SE.
MAC key writing
Calibration data (IP characteristics value) writing
note TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. The data stored in M.U.T.-III SE must be written in new TCM.
Clutch point learning
Select learning (Drive/Reverse learning)
G sensor calibration
