ECD SYSTEM(w/ Glow Plug Controller) INITIALIZATION

Tip:
  • After replacing any of the injector assemblies, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS. If any of the injector assemblies and the ECM are replaced at the same time, perform the same initialization/registrations as when replacing the ECM.

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

  • After replacing the No. 2 exhaust manifold, perform the "DPF Deterioration Record Clear" function using the GTS. If the No. 2 exhaust manifold and the ECM are replaced at the same time, perform the same initialization/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 GTS. If the engine assembly and the ECM are replaced at the same time, perform the same initialization/registrations as when replacing the ECM.

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

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Clear the DTCs.

      Powertrain > Engine and ECT > Clear DTCs

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

      Tip:

      The ignition switch must be turned off before DTC recurs.

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

  2. Pilot Quantity Learning Values Reset (When replacing all injector assemblies)

    Tip:

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

    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 / Engine and ECT / Utility / Pilot Quantity Learning Values Reset.

      Powertrain > Engine and ECT > Utility

      Tester Display

      Pilot Quantity Learning Values Reset

    5. A295526

      Press "Next".

      Tip:

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

    6. A295527

      Select "All Injectors" and press "NEXT".

    7. A295528

      Press "EXIT".

  3. Pilot Quantity Learning Values Reset (When replacing specific any of the injector assemblies)

    Tip:

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

    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 / Engine and ECT / Utility / Pilot Quantity Learning Values Reset.

      Powertrain > Engine and ECT > Utility

      Tester Display

      Pilot Quantity Learning Values Reset

    5. A295526

      Press "Next".

      Tip:

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

    6. A295529

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

    7. A295530

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

    8. A295528

      Press "EXIT".

  4. DPF Deterioration Record Clear

    Tip:
    • 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 GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

      Powertrain > Engine and ECT > Utility

      Tester Display

      DPF Deterioration Record Clear

    5. A295531

      Press "Next".

      Tip:

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

    6. A295532

      Press "Next".

  5. A/F Sensor Compensation Reset (When replace Air Fuel Ratio Sensor (Bank 1 Sensor 1))

    Tip:

    When an air fuel ratio sensor (bank 1 sensor 1) is replaced, the A/F sensor compensation learning value stored in the ECM must be reset.

    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 / Engine and ECT / Utility / A/F Sensor Compensation Reset.
