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. |
When replacing TCM and transaxle assembly simultaneously, perform the following work. For work procedure, refer to
Work Procedure.
note | The CD provided with the new transaxle assembly contains important calibration data that must be installed with M.U.T.-III SE after installation of the new transaxle assembly. Never discard the CD. |
WORK BEFORE TCM AND TRANSAXLE ASSEMBLY REPLACEMENT
- Current calibration data checking
- New transaxle assembly serial number checking
WORK AFTER TCM AND TRANSAXLE ASSEMBLY 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. |
- Checking that the serial number recorded on the attached CD matches the serial number on transaxle assembly.
- MAC key writing
- Calibration data (IP characteristics value) writing
note | TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, after replacing transaxle assembly, it is necessary to write new data in TCM. |
- New calibration data checking
- Select learning (Drive/Reverse learning)
- Clutch point learning
- Select learning (Drive/Reverse learning)
- G sensor calibration
- Shift actuator learning
