Description
cautionWhen 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.
noteThe 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
    noteSince 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
    noteTCM 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
