PROCEDURE

  1. ECU EXCHANGE

    1. for CVT:

      Note:

      When replacing the engine stop and start ECU with a new one, make sure to download the previous status (number of starter operations) of the old engine stop and start ECU. After replacing the engine stop and start ECU, turn the ignition switch to ON and wait 20 seconds, then confirm that "OK" is displayed for the Data List item "Oper Prohibition (O/P Air Bleeding)". Then upload the previous status (number of starter operations) to the engine stop and start ECU.

      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

      3. Enter the following menus: Powertrain / Stop and Start / Utility / ECU Exchange.

        Powertrain > Stop and Start > Utility

        Tester Display

        ECU Exchange

      4. According to the display on Utility by the GTS, download the previous status (the number of starter operations) from the old engine stop and start ECU to the GTS.

      5. According to the display on the GTS, upload the previous status (the number of starter operations) from the GTS to the new engine stop and start ECU.

      6. Replace the engine stop and start ECU.

        Click here

      7. According to the GTS display, upload the previous status (the number of starter operations) from the GTS to the new engine stop and start ECU.

  2. CLEAR NUMBER OF STARTER OPERATIONS

    Note:

    After the starter assembly is replaced, be sure to clear the number of starter operations stored in the engine stop and start ECU.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Stop and Start / Utility / Starter Exchange.

      Powertrain > Stop and Start > Utility

      Tester Display

      Starter Exchange

  3. RESET AIR CONDITIONING INFORMATION

    Note:

    After replacing the engine stop and start ECU or air conditioning amplifier assembly, initialization of the air conditioning information in the engine stop and start ECU is necessary.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Stop and Start / Utility / Reset A/C Information.

      Powertrain > Stop and Start > Utility

      Tester Display

      Reset A/C Information

  4. LEARNING AIR CONDITIONING INFORMATION

    Tip:

    When initialization of the air conditioning information is complete, air conditioning information learning is automatically performed. If the learning cannot be performed properly, inspect the CAN communication system.

  5. CLEAR THE ZERO POINT CALIBRATION DATA

    Note:

    • After replacing the engine stop and start ECU or airbag sensor assembly, perform deceleration sensor zero point clear and calibration.

    • 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.

    1. Turn the ignition switch off.

    2. for CVT:

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

      for Manual Transaxle:

      Move the shift lever to neutral and apply the parking brake.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch to ON.

      Tip:

      Do not start the engine.

    5. Turn the GTS on.

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

      Powertrain > Stop and Start > Utility

      Tester Display

      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 output DTC P1589 and blink the stop and start cancel indicator light.

    7. Turn the ignition switch off.

  6. PERFORM ZERO POINT CALIBRATION OF THE DECELERATION SENSOR

    Note:

    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. Connect the GTS to the DLC3.

    2. for CVT:

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

      for Manual Transaxle:

      Move the shift lever to neutral and apply the parking brake.

    3. Turn the ignition switch to ON.

      Tip:

      Do not start the engine.

    4. Check that the parking brake is applied.

    5. Turn the GTS on.

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

      Powertrain > Stop and Start > Utility

      Tester Display

      Deceleration Sensor Zero Point Calibration
      Tip:

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

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

      Note:

      If zero point calibration fails, perform the registration procedure again from "CLEAR THE ZERO POINT CALIBRATION DATA".

  7. CLEAR THE INTEGRATED CURRENT VALUE

    Tip:

    After charging the battery, perform the integrated current value initialization.

    If the Data List item "Integrated Current" indicates 0 or more, initialization is not necessary.

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Stop and Start / Utility / Integrated Current Value Initialization.

      Powertrain > Stop and Start > Utility

      Tester Display

      Integrated Current Value Initialization

  8. AIR BLEED OIL PUMP ASSEMBLY WITH MOTOR (for CVT)

    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 ignition switch to ON.
