CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM INITIALIZATION

Note


  • Performing reset memory will clear the learned values of both the deceleration sensor zero point calibration and CVT oil pressure calibration. Make sure to perform reset memory, deceleration 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 sensor assembly) (w/ VSC)

    • Deceleration sensor (w/o VSC)

    • Skid control ECU (Brake actuator assembly) (w/o VSC)

  • After performing reset memory, always perform 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 ignition switch off.

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

      3. Connect the GTS to the DLC3.

      4. Turn the ignition switch to ON.

        Note

        Do not start the engine.

      5. Turn the GTS on.

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


        Powertrain > Engine and ECT > Utility
        Tester Display
        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 ignition switch is ON.

    2. Perform deceleration sensor zero point calibration as follows:


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

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


        Powertrain > Engine and ECT > Utility
        Tester Display
        Deceleration Sensor Zero Point Calibration

        Tech Tips


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

        • If "Error" is displayed on the screen and DTC P1589 is output (confirm the DTC detection conditions), the yaw rate and acceleration sensor (airbag sensor assembly)*1 or deceleration sensor*2 circuit may have a malfunction.

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


          • *1: w/ VSC

          • *2: w/o VSC

    3. Perform CVT oil pressure calibration as follows:


      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.

        Tech Tips

        CVT oil pressure calibration is performed with the ignition switch ON (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 higher.

        • CVT oil temperature is -5°C (23°F) or less or 100°C (212°F) or higher.

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

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


        Powertrain > Engine and ECT > Utility
        Tester Display
        CVT Oil Pressure Calibration

        Tech Tips


        • During 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.
