CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM INITIALIZATION

Note


  • Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 0 point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:

    Replaced Part

    • Continuously variable transaxle assembly

    • ECM

    • Oil pressure sensor

    • Yaw rate and acceleration sensor

  • After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.


  1. RESET MEMORY


    1. Perform the reset memory as follows:


      1. Turn the ignition switch off.

      2. Move the shift lever to P and apply the parking brake.

      3. Connect the intelligent tester to the DLC3.

      4. Turn the ignition switch to ON.

        Note

        Do not start the engine.

      5. Turn the tester on.

      6. Perform the Reset Memory procedure from the main menu.

      7. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.

      8. Press "Next".

    2. Deceleration Sensor 0 Point Calibration

      Note


      • Keep the vehicle stopped, level and stable during the calibration.

      • Make sure that the shift lever is in P.

      • Make sure that the engine is stopped.

      • Make sure that the ignition switch is ON.

      • To prevent idling vibrations, do not start the engine.


      1. Perform the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) as follows:

        (1) Turn the ignition switch to ON and wait at least 2 seconds.

        Enter the following menus: Powertrain / Engine and ECT / Utility / Deceleration Sensor 0 Point Calibration.*1

        Press "Next".*2

        Tech Tips


        • When "Complete" is displayed on the screen, the deceleration sensor 0 point calibration is completed.

        • If "Error" is displayed on the screen and DTC P1589 is output (for the detection conditions for DTC P1589, refer to the following Click here, the deceleration sensor circuit may have a malfunction.

        • Shaking or vibrating the vehicle during 0 point calibration may cancel calibration. If "Error" is displayed on the screen and DTC P1589 is not output, perform steps *1 and *2 again.

    3. CVT Oil Pressure Calibration


      1. Turn the ignition switch off and wait at least 30 seconds.

      2. Turn the ignition switch to ON and wait at least 2 seconds.

        Note

        Do not start the engine.

      3. Start the engine and wait at least 5 seconds.

      4. Enter the following menus: Powertrain / Engine and ECT / Utility / CVT Oil Pressure Calibration.

      5. Press "Next".

        Tech Tips


        • During the CVT oil pressure calibration, the engine idle speed will increase.

        • When "Complete" is displayed on the screen, the CVT oil pressure calibration is completed.

        • The learned values cannot be cleared by only disconnecting and reconnecting the cable to the negative (-) battery terminal.
