CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM INITIALIZATION

Note


  • Performing reset memory/initialization will clear the learned values of the deceleration sensor (deceleration sensor 0 point calibration)*1 and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, deceleration sensor 0 point calibration*1, 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

    • Airbag sensor assembly (Yaw rate sensor)*1

  • After reset memory, always perform deceleration sensor (deceleration sensor 0 point) calibration*1 first, and then the CVT oil pressure calibration.


  • *1: w/ Stop and start system only


  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 (w/ Stop and start system only)

      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 deceleration 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 the 0 point calibration may cancel the 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.

    4. Air bleeding of the electric oil pump (w/ Stop and start system only)


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

      3. Turn the tester on.

      4. Enter the following menus: Powertrain / Stop and Start / Utility / Oil Pump Air Bleeding.

      5. In accordance with the display on the tester, perform the oil pump air bleeding.

        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.
