STOP AND START SYSTEM, Diagnostic DTC:P1589

DTC Code DTC Name
P1589 G Sensor Zero Point Calibration Incomplete

DESCRIPTION

In case of driving the vehicle before performing calibration of the deceleration sensor 0 point it detects the diagnosis code.

DTC No. DTC Detection Condition Trouble Area
P1589

Both of the following conditions are met for 5 seconds or more (1 trip detection logic):


  • The vehicle speed is 3 km/h (2 mph) or more and VSC communication is normal.

  • Deceleration sensor zero point calibration is incomplete.

  • The deceleration sensor zero point calibration has not been performed

  • Airbag sensor assembly (Yaw rate sensor)

  • Engine stop and start ECU

CONFIRMATION DRIVING PATTERN


  1. After troubleshooting, perform the following steps to recheck for DTCs.

    Tech Tips


    • If the cable is disconnected from the battery terminal, stop and start control is prohibited until refresh charge is completed.

      In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item Status of Battery Charge Control changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the battery temperature at 11°C (52°F) or higher, the refresh charge will be completed.)

    • If the GTS is not available and the Data List item Status of Battery Charge Control cannot be checked, charge the battery by idling the engine for approximately 5 to 60 minutes or driving the vehicle, and then drive the vehicle and check that stop and start control operates. If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.

    • After the refresh charge completes, turn the ignition switch off, wait for at least 30 seconds, and then start the engine again. If the vehicle enters refresh charge mode again while the engine is idling, the initial refresh charge did not properly complete, so wait for the refresh charge to complete.

    • Allow the engine to idle for 3 minutes after the engine warms up and check that the engine speed is within 50 rpm of the target idle speed.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch on and turn the GTS on.

    3. Clear the DTCs Click here.

    4. Start the engine and warm it up.

    5. Drive the vehicle at 3 km/h (1.9 mph) or more for 5 seconds or more.

      CAUTION:

      When performing the confirmation driving pattern, obey all speed limits and traffic laws.

    6. Check that no DTCs are output Click here.

  2. Check if the stop and start system operates normally.

    1. for Manual Transaxle


      1. Start the engine and warm it up.

      2. Turn the air conditioning system off.

      3. Drive the vehicle at 7 km/h (4.3 mph) or more.

        CAUTION:

        When performing the confirmation driving pattern, obey all speed limits and traffic laws.

      4. Stop the vehicle, move the shift lever to neutral and release the clutch pedal.

      5. Allow the engine to stop by stop and start control.

      6. Depress the clutch pedal and start the engine.

CAUTION / NOTICE / HINT

Note


  • Before replacing the engine stop and start ECU, read the number of starter operations and write it into a new engine stop and start ECU Click here.

  • After replacing the engine stop and start ECU or air conditioning amplifier assembly, reset and perform learning of the air conditioning information in the engine stop and start ECU Click here.

  • After replacing the engine stop and start ECU or airbag sensor assembly, clear and calibrate the deceleration sensor zero point in the engine stop and start ECU Click here.

Tech Tips

DTCs for the stop and start system are not cleared even if the malfunction has been repaired. After repairing the malfunction, be sure to clear the DTCs Click here.

Using the GTS, read the freeze frame data before troubleshooting. System condition information is recorded as freeze frame data the moment a DTC is stored. This information can be useful when troubleshooting Click here.

PROCEDURE


  1. PERFORM INITIALIZATION (DECELERATION SENSOR 0 POINT CALIBRATION)

    Note


    • Once the zero point is stored, it cannot be overwritten until the data is cleared. Be sure to perform zero point clear and calibration after replacing the airbag sensor assembly.

    • Park the vehicle on a level surface (grade: +/-1%). Do not shake the vehicle or open/ close any of the doors during zero point calibration. To avoid vibration caused by the engine idling, do not start the engine.


    1. Clear the zero point calibration data. (*1)


      1. Turn the ignition switch off.

      2. Connect the GTS to the DLC3.

      3. Move the shift lever to P and apply the parking brake. (for CVT)

      4. Move the shift lever to neutral and apply the parking brake. (for Manual Transaxle)

      5. Turn the ignition switch to ON.

        Tech Tips

        Do not start the engine.

      6. Turn the GTS on.

      7. Enter the following menus: Powertrain / Stop and Start / Utility / Deceleration Sensor Zero Point Clear.

        Note

        When the deceleration sensor zero point is cleared, the system information stored in the engine stop and start ECU is also cleared. If the vehicle is driven for 5 seconds or more at 3 km/h (2 mph) or more in this condition, the engine stop and start ECU will store DTC P1589 and blink the stop and start cancel indicator light.

      8. Turn the ignition switch off.

    2. Perform zero point calibration of the deceleration sensor.


      1. Check that the shift lever is in P. (for CVT)

      2. Check the shift lever in neutral. (for Manual Transaxle)

      3. Connect the GTS to the DLC3.

      4. Check that the parking brake is applied and the brake warning light is illuminated.

      5. Turn the ignition switch to ON.

        Tech Tips

        Do not start the engine.

      6. Turn the GTS on.

      7. Enter the following menus: Powertrain / Stop and Start / Utility / Deceleration Sensor Zero Point Calibration.

        Tech Tips

        If DTC P1589 is stored, the stop and start cancel indicator light will blink.

      8. While keeping the vehicle stationary, follow the prompts on the GTS screen. Check that "Complete" is displayed on the GTS screen.
