СИСТЕМА ECD ИНИЦИАЛИЗАЦИЯ

Tech Tips


  • After replacing fuel injector(s), perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the intelligent tester. If fuel injector(s) and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.

  • After replacing the air fuel ratio sensor, perform the "A/F Sensor Compensation Reset" function using the intelligent tester. If the air fuel ratio sensor and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.

  • After replacing the DPF catalytic converter, perform the "DPF Deterioration Record Clear" function using the intelligent tester. If the DPF catalytic converter and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.

  • After replacing the engine assembly, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the intelligent tester. If the engine assembly and the ECM are replaced at the same time, perform the same initializations/registrations as when replacing the ECM.

  • The "DPF Deterioration Record Clear" function appears on the intelligent tester display only for vehicles with the DPF system.


  1. When the diesel throttle body assembly, EGR valve assembly or turbocharger sub-assembly is replaced, perform initialization


    1. Connect the intelligent tester to the DLC3.

    2. Clear DTCs Click here.

    3. Turn the ignition switch off within 10 seconds of clearing DTCs, and wait for 30 seconds.

      Tech Tips

      The ignition switch must be turned off before DTC recurs.

    4. Turn the ignition switch to ON and wait for 10 seconds or more.

  2. Pilot Quantity Learning Values Reset (When replace all injectors)

    Tech Tips

    When any injectors and/or the engine assembly are replaced, the pilot quantity learning values stored in the ECM must be reset.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / Pilot Quantity Learning Values Reset.

    4. A011BXD

      Press "Next".

      Tech Tips

      Confirm that the ignition switch is ON and the engine is stopped.

    5. A011ALD

      Select "All Injectors" and press "NEXT".

    6. A011B8O

      Press "EXIT".

  3. Pilot Quantity Learning Values Reset (When replacing specific injector(s))

    Tech Tips

    When any injectors and/or the engine assembly are replaced, the pilot quantity learning values stored in the ECM must be reset.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / Pilot Quantity Learning Values Reset.

    4. A011BXD

      Press "Next".

      Tech Tips

      Confirm that the ignition switch is ON and the engine is stopped.

    5. A0119VE

      Select "Specific Injector(s)" and press "NEXT".

    6. A0118EN

      Select the cylinder(s) where injector(s) was replaced, and press "NEXT".

    7. A011B8O

      Press "EXIT".

  4. DPF Deterioration Record Clear

    Tech Tips


    • This value is the ash accumulation volume in the DPF catalytic converter calculated by the ECM. If the ash accumulation volume in the DPF catalytic converter increases, the difference in pressure in front of and behind the DPF catalytic converter will increase. The difference in pressure in front of and behind the DPF catalytic converter is offset depending on the volume of accumulated ash.

    • When a DPF catalyst is replaced, the DPF deterioration record stored in the ECM must be cleared.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / DPF Deterioration Record Clear.

    4. A011BH8

      Press "Next".

      Tech Tips

      Confirm that the ignition switch is ON and the engine is stopped.

    5. A011AW9

      Press "Next".

  5. A/F Sensor Compensation Reset

    Tech Tips

    When an air fuel ratio sensor is replaced, the A/F sensor compensation learning value stored in the ECM must be reset.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON and turn the tester on.

    3. Enter the following menus: Powertrain / Engine and ECT / Utility / A/F Sensor Compensation Reset.

    4. A0119FX

      Press "Next".

      Tech Tips

      Confirm that the ignition switch is ON and the engine is stopped.
