CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM INITIALIZATION

Note


  • Performing reset memory will clear the learned values of both the yaw rate sensor (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate 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 sensor

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

Tech Tips

Intelligent tester only:


  1. RESET MEMORY/CALIBRATION


    1. Perform reset memory as follows:


      1. Turn the engine 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 engine switch on (IG).

        Note

        Do not start the engine.

      5. Turn the intelligent tester on.

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

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

        • Make sure that the engine switch is on (IG).

    2. Perform yaw rate sensor calibration (deceleration sensor 0 point calibration) as follows:


      1. Turn the engine switch on (IG) and wait at least 2 seconds.

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

        Tech Tips


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

        • If "Error" is displayed on the intelligent tester, the deceleration sensor circuit may have a malfunction.

        • Shaking or vibrating the vehicle during 0 point calibration may cancel the calibration. If "Error" is displayed on the intelligent tester, perform calibration.

    3. Perform CVT oil pressure calibration as follows:


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

      2. Turn the engine switch on (IG) 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.

        Tech Tips


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

        • When "Complete" is displayed on the intelligent tester, 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.
