MULTI-MODE MANUAL TRANSAXLE SYSTEM


  1. OUTLINE


    1. The EC65A Multi-mode Manual Transaxle (M-MT) is EC65 manual transaxle* with a clutch actuator assembly and shift and select actuator assembly. The operation of the clutch actuator assembly and shift and select actuator assembly are controlled by the TCM.

      Tech Tips

      *: For details, see the EC65 Manual Transaxle.

    2. The M-MT uses a shift-by-wire system in which the TCM changes gears using actuators in accordance with the shift lever position that has been detected through the shift lever position sensor and the transmission shift main switch in the floor shift shift lever assembly.

    3. The M-MT has 2 modes (E-mode and M-mode). As a result, good fuel efficiency, ease of driving (in E-mode) and sporty driving (in M-mode) are realized.


      1. The E-mode shifts automatically to suit the driving conditions. In the E-mode, the driver can select from 2 shift patterns: (normal [E] pattern and sporty [Es] pattern). The normal [E] pattern is always selected at the time the engine is started.

      2. The M-mode allows the driver to manually operate the shift lever and shift paddle switch (transmission shift switch assembly) to shift gears without applying the clutch.

  3. PRECAUTION


    1. When removing or installing any part related to the M-MT system as shown in the following list, perform the 4 general service steps indicated below to reset the system:


      1. Bleed the clutch line

      2. Initialization of TCM

      3. M-MT system learning

      4. Synchronization position calibration

    2. Since a CSC is used in the clutch system, it is necessary to bleed the clutch fluid lines after a clutch related part has been replaced or the transaxle or engine has been removed.


      1. The clutch hydraulic system needs to function normally before performing other general service procedures, such as initialization of TCM and multi-mode manual transaxle system learning. Therefore, bleed the clutch fluid lines before performing these other procedures. For details, refer to the Repair Manual.

    3. Perform the 3 general service procedures (initialization of TCM, learning of M-MT system and synchronization position calibration) upon the completion of the removal and reinstallation of any part related to the M-MT system. For details, refer to the Repair Manual.

      General Service Procedure Outline
      Initialization of TCM

      • The TCM stores the calibration/learned values for actuator positions, clutch synchronization position etc., data and DTCs. This information in the TCM can be initialized through one of the 2 ways described below:


        • Use the intelligent tester after connecting it to the DLC3.

        • Use SST (09843-18040) and connect it to the TC and CG terminals of the DLC3, and operate the brake pedal and shift lever.
      Learning of M-MT System Adjusts the clutch clamp position accurately including all related parts on vehicle. Each part has a tolerance and is designed to have a certain range of stroke in the clutch clamp position, and this operation calibrates the actual clamp position.
      Checks shift and select actuator assembly accurate position for shifting by operating the actuators for shift and select. If the initial position is shifted with designed one, the TCM learns the actual standard position for shift and select side.

      • Before allowing the M-MT system to learn, the TCM must be initialized first. The M-MT system can learn through one of the 2 ways described below:


        • Use the intelligent tester and connect it to the DLC3.

        • Turn the ignition switch off to ON, and wait for 40 seconds. After that, turn the ignition switch again from ON to off, and wait for 15 seconds or more. Then, start the engine, and wait for 10 seconds.
      Synchronization Position Calibration After initialization and learning, the combination of the parts or characteristics of the parts themselves would make the change of the transaxle synchronization position under actual driving. The TCM learns the actual standard position as standard value for smooth shifting.
      Driving with M-mode, shift up from 1st to 6th, and shift down from 6th to 1st at the specified vehicle speed for each shifting condition.
