CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM INITIALIZATION

Note


  • Performing Reset Memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform Reset Memory, yaw rate and acceleration sensor zero 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 (Airbag ECU assembly)

  • After performing Reset Memory, always perform yaw rate and acceleration sensor (deceleration sensor zero point) calibration first, and then CVT oil pressure calibration.


  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 GTS to the DLC3.

      4. Turn the engine switch on (IG).

        Note

        Do not start the engine.

      5. Turn the GTS on.

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

        Note


        • Keep the vehicle stopped, level and stable during the calibration (Inclination: 0 +/- 0.25°).

        • 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.

    2. Perform deceleration sensor zero 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 Zero Point Calibration.

        Tech Tips


        • When "Complete" is displayed on the screen, deceleration sensor zero point calibration is complete.

        • If "Error" is displayed on the screen and DTC P1589 is output (for the detection conditions for DTC P1589), refer to P1589, the deceleration sensor circuit may be malfunctioning.

        • Shaking or vibrating the vehicle during deceleration sensor zero point calibration may cancel calibration. If "Error" is displayed on the screen and DTC P1589 is not output, perform calibration again.

    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.

        Tech Tips

        CVT oil pressure calibration is performed with the engine switch on (IG) (engine stopped). However, the calibration cannot be performed under the following conditions:


        • Oil pressure sensor value is 0.065 MPa (0.663 kgf/cm2, 9.43 psi) or more.

        • CVT oil temperature is -5°C (23°F) or less or 120°C (248°F) or more.

      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 screen, CVT oil pressure calibration is complete.

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

  2. BLEED AIR FROM OIL PUMP ASSEMBLY WITH MOTOR

    Note

    Bleed the oil pump assembly with motor (continuously variable transaxle assembly) after removing and installing the continuously variable transaxle assembly or replacing the CVT fluid.


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

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