MULTI-MODE MANUAL TRANSAXLE SYSTEM INITIALIZATION


  1. INITIALIZATION AND LEARNING USING INTELLIGENT TESTER

    Tech Tips


    • By using an intelligent tester, initialization and learning of the multi-mode manual transmission system can be performed sequentially. Under manual operation (not using intelligent tester), initialization and learning must be performed individually.

    • The learning values and the DTC history of the multi-mode manual transmission system are stored in the EEP ROM in the transmission control ECU. The stored information is not cleared even when the negative terminal of the battery is disconnected. To clear all the stored information, initialize the transmission control ECU.

    • Perform the procedure below to ensure that the initialized transmission control ECU stores the adjusted clutch position (stopper position, clamp position, and standby position) or gear position (shift position and select position).

    • If initialization cannot be performed normally, there may be a malfunction in the shift lever position sensor, NE signals, or CAN communication.

    • When replacing the following parts, proceed with the operation in the order listed in the table below.

    • Transmission assembly

    26. Turn the intelligent tester OFF and turn the ignition switch to OFF.

    27. Wait at least 20 seconds.

    28. Turn the ignition switch to ON.

    29. Depress the brake pedal with the shift lever position in the N position.

    30. Start the engine and wait at least 10 seconds.

    31. Shift the gear from neutral to any other position.

      Tech Tips


      • When [Initialization of transmission] was selected at step (p), add the following step between steps (w) and (x).

        Additional step: (w') Turn the ignition switch to ON and wait at least 30 seconds.

      • If the Initialization and Learning operations fail, perform the operations again from step (a) more than 15 seconds after turning the ignition switch to OFF.

      • Perform Synchronization Position Calibration after performing Initialization of transmission or Initialization of ECU.

      • Shifting the gear from neutral to any other position at last, the transmission control ECU learns the standby point. At this time, the value of Learn-Clutch Standby Point in the Data List changes from [Notexec] to [Exec].
