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 engine switch on (IG).

   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 engine switch on (IG).

   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

   Tech Tips

   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 ECU 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 ECU assembly.

   
   

   1. Turn the engine switch off.

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

   3. Connect the GTS to the DLC3.

   4. Turn the engine switch on (IG).

      Tech Tips

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

   7. Turn the engine 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. Check that the shift lever is in P.

   3. Turn the engine switch on (IG).

      Tech Tips

      Do not start the engine.

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

   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

      Tech Tips

      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

   Tech Tips

   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 engine switch on (IG).

   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
