СИСТЕМА ECD ИНИЦИАЛИЗАЦИЯ


  1. DIESEL THROTTLE BODY INITIALIZATION PROCEDURE

    Tech Tips

    When the diesel throttle body assembly 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. SUPPLY PUMP INITIALIZATION PROCEDURE

    Tech Tips

    After replacing the fuel supply pump assembly and/or ECM:


    • If the engine is defective or stalls immediately after startup, the learned values of the ECM must be initialized. The engine can be initialized through the GTS or by connecting DLC3 terminals.

    • If the engine starts normally, initialization is not necessary. Perform the steps labeled procedure "A" and procedure "B" only.


    1. B003NCO

      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 / Utility / Supply Pump Initialization.


      Powertrain > Engine > Utility
      Tester Display
      Supply Pump Initialization

    5. Press "Next".

    6. B003OT7

      Press "Next".

    7. B003PJD

      Press "Exit".

    8. Start the engine to check if the initialization is complete. If the engine cannot be started, repeat the initialization procedures from the beginning (Procedure "A").

    9. Idle the engine for at least 1 minute under the following conditions: (Procedure "B")


      • The engine coolant temperature is 75°C (167°F) or higher.

      • The fuel temperature is 20°C (68°F) or higher.

      Note

      Do not race the engine immediately after starting the engine. After warming up the engine, racing the engine is acceptable.

      Tech Tips


      • The engine coolant temperature can be estimated by touching the outlet hose.

      • The fuel temperature can be estimated by using the ambient temperature as a substitute.

      • If the engine coolant temperature is difficult to estimate, use the GTS and enter the following menus: Powertrain / Engine / Data List / Coolant Temp.

    10. Initialization is complete.
