DTC P1589 Acceleration Sensor Learning Value


DESCRIPTION

  1. *1: w/ VSC
  2. *2: w/o VSC
The ECM stores DTC P1589 if the ECM or other components are replaced that require the yaw rate sensor assembly*1 or deceleration sensor*2 to be calibrated (deceleration sensor 0 point calibration) and calibration is terminated or the vehicle is driven before calibration is complete.

INSPECTION PROCEDURE

  1. *1: w/ VSC
  2. *2: w/o VSC
1.PERFORM INITIALIZATION (DECELERATION SENSOR 0 POINT CALIBRATION)
NOTICE:
  1. If the CVT oil pressure calibration is performed before the deceleration sensor 0 point calibration, DTC P1589 is stored. In this case, perform the steps below to return the system to normal.
  2. Always perform 0 point calibration with the vehicle on level ground.
  3. Do not shake or vibrate the vehicle during 0 point calibration.

  1. Turn the ignition switch off.

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

  1. Connect the tester to the DLC3.

  1. Turn the ignition switch to ON.

    NOTICE:
    Do not start the engine.

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

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

    HINT:
    1. When "Complete" is displayed on the screen, the deceleration sensor 0 point calibration is completed.
    2. If "Error" is displayed on the screen and DTC P1589 is output (confirm the DTC detection conditions), the yaw rate sensor assembly*1 or deceleration sensor*2 circuit may have a malfunction.
    3. Shaking or vibrating the vehicle during 0 point calibration may cancel calibration. If "Error" is displayed on the screen and DTC P1589 is not output, perform calibration again.

2.PERFORM INITIALIZATION (CVT OIL PRESSURE CALIBRATION)
NOTICE:
Do not initialize the learned values by performing reset memory.

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

  1. Connect the intelligent tester to the DLC3.

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

    NOTICE:
    Do not start the engine.

  1. Turn the intelligent tester on.

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

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

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

    HINT:
    1. During the CVT oil pressure calibration, the engine idle speed will increase.
    2. When "Complete" is displayed on the screen, the CVT oil pressure calibration is completed.
    3. The learned values cannot be cleared by only disconnecting and reconnecting the cable to the negative (-) battery terminal.

  1. Check that no DTC is stored.

6.PERFORM INITIALIZATION
NOTICE:
  1. Performing reset memory will clear the learned values of both the yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor assembly*1 or deceleration sensor*2 0 point calibration and CVT oil pressure calibration when replacing any of the parts shown in the following table:
    Replaced Part
    1. Continuously variable transaxle assembly
    2. ECM
    3. Oil pressure sensor
    4. Yaw rate sensor assembly (w/ VSC)
    5. Deceleration sensor (w/o VSC)
    6. Brake actuator assembly (skid control ECU)
  2. After performing reset memory, always perform yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.
  3. Always perform 0 point calibration with the vehicle on level ground.
  4. Do not shake or vibrate the vehicle during 0 point calibration.
