ECD SYSTEM (w/o DPF) INITIALIZATION

Tech Tips

After replacing the supply pump and/or the ECM:

The ECM's learned values must be initialized. The engine can be initialized through the intelligent tester or by short-circuiting DLC3 terminals.


  1. SUPPLY PUMP INITIALIZATION PROCEDURE


    1. A01BBELE01

      Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON.

      Note

      Do not start the engine.

    3. Turn the tester ON.

    4. Select the following menu items: Powertrain / Engine / Utility / Supply Pump Initialization.

    5. Press "Next".

    6. A01BAGWE01

      Press "Next".

    7. A01BAU9E01

      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.

    9. Idle the engine for at least 1 minute under the following conditions:


      • The water temperature is 60°C (140°F) or more.

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

      Note

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

      Tech Tips


      • If the temperature is difficult to estimate, use the intelligent tester and select the following menu items: Powertrain / Engine / Data List / Coolant Temp and Fuel Temperature.

    10. Initialization is complete.
