ECD SYSTEM(w/ DPF) INITIALIZATION


  1. INITIALIZATION PROCEDURE FOR DIESEL THROTTLE BODY ASSEMBLY, ELECTRIC EGR CONTROL VALVE ASSEMBLY AND TURBOCHARGER NOZZLE VANE CONTROL ACTUATOR

    Tech Tips

    When the diesel throttle body assembly, electric EGR control valve assembly or turbocharger nozzle vane control actuator is replaced, perform initialization


    1. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    2. Turn the ignition switch off and wait for 30 seconds or more.

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

  2. CATALYST RECORD OF DPF THERMALDETERIORATION CLEAR FUNCTION

    Tech Tips

    When the exhaust manifold converter sub-assembly (DPF catalyst) is replaced, the catalyst record of DPF thermal deterioration 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 menu options in this order: Powertrain / Engine and ECT / Utility / Catalyst Record Clear.


      Powertrain > Engine > Utility
      Tester Display
      Catalyst Record Clear
    5. Press "Next".

    6. Press "Exit".

    7. Enter the menu options in this order: Powertrain /Engine and ECT / Utility / DPF Deterioration Record Clear.


      Powertrain > Engine > Utility
      Tester Display
      DPF Deterioration Record Clear
    8. Press "Next".

    9. Press "Exit".

  3. CRANK TIME COMPENSATION RESET FUNCTION


    • This procedure uses the GTS to perform "Crank Time Compensation Reset".

    • When replacing the timing rotor (engine assembly), perform "Crank Time Compensation Reset".

    Tech Tips


    • B003SD4

      If an error occurs during compensation reset, check the vehicle condition, and then perform compensation reset again.

    • A communication malfunction may occur if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility / Crank Time Compensation Reset.


      Powertrain > Engine and ECT > Utility
      Tester Display
      Crank Time Compensation Reset
    5. B003L4K

      When the first screen is displayed, check the vehicle condition and push "Next".

    6. B003PVC

      When the screen indicating reset completion is displayed, push "Exit".

  4. A/F SENSOR COMPENSATION RESET FUNCTION


    • This procedure uses the GTS to perform "A/F Sensor Compensation Reset".

    • When replacing the air fuel ratio sensor, replace the sensor and then perform "A/F Sensor Compensation Reset".

    Tech Tips


    • B003R0P

      If an error occurs during compensation reset, check the vehicle condition, and then perform compensation reset again.

    • A communication malfunction may occur if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    3. Turn the GTS on.

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


      Powertrain > Engine > Utility
      Tester Display
      A/F Sensor Compensation Reset
    5. B003P83

      When the first screen is displayed, check the vehicle condition and press "Next".

    6. B003QS2

      When the screen indicating reset completion is displayed, press "Exit".
