CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P1589

DTC Code DTC Name
P1589 Acceleration Sensor Learning Value

DESCRIPTION

The ECM stores DTC P1589 if the yaw rate sensor 0 point calibration is not performed or is failed after system components such as the ECM are replaced.

DTC No.

  1. The vehicle speed is 2 km/h (1.2 mph) or more.

  2. The yaw rate sensor 0 point calibration is not completed.

  3. -

  4. 1 trip detection logic

  • The yaw rate sensor 0 point calibration is performed.

  • Vehicle is stabilized during the yaw rate sensor 0 point calibration

  • Airbag sensor assembly (Yaw rate sensor)

  • ECM

PROCEDURE


  1. PERFORM INITIALIZATION (DECELERATION SENSOR 0 POINT CALIBRATION)

    Note


    • If the CVT oil pressure calibration is performed before the deceleration sensor 0 point calibration, DTC P1589 is stored. In this case, perform steps *1, *2, *3, *4 and *5 to return the system to normal.

    • Always perform the 0 point calibration with the vehicle on level ground.

    • Do not shake or vibrate the vehicle during the 0 point calibration.


    1. Turn the ignition switch off.*1

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

    3. Turn the ignition switch to ON.*3

      Note

      Do not start the engine.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.*4

    5. Enter the following menus: Powertrain / ECT / Utility / Deceleration Sensor 0 Point Calibration.*5

      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 (confirm the DTC detection conditions), 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 step *5 again.

  2. PERFORM CVT OIL PRESSURE CALIBRATION

    Note

    Do not initialize the learned values.


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

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

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

      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.

    6. Check for DTCs again.

  3. CHECK AIRBAG SENSOR ASSEMBLY (YAW RATE SENSOR)


    1. Check the airbag sensor assembly (yaw rate sensor) for any inclination, bracket deformation or installation clearance.

      OK
      The airbag sensor assembly (yaw rate sensor) is installed correctly.

    SECURELY INSTALL AIRBAG SENSOR ASSEMBLY (YAW RATE SENSOR)

    OK

  4. READ VALUE USING INTELLIGENT TESTER (G SENSOR)


    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 / Engine and ECT / Data List.

    5. In accordance with the display on the tester, read the Data List.
