Ecd System Initialization

  1. When using intelligent tester

  1. When not using intelligent tester

Ecd System -- Initialization


HINT:
After replacing the supply pump and/or the ECM.
  1. If the engine is defective or stalls immediately after startup, the ECM's learned values must be initialized. The engine can be initialized through the intelligent tester or by short circuit DLC3 terminals.
  2. If the engine starts normally, initialization is not necessary. Perform the "Idle the engine" procedure below only.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch ON.

    NOTICE:
    Do not start the engine.

  3. Turn the intelligent tester ON.

  4. Enter the following menus: Powertrain / Engine / Utility / Supply Pump Initialization.

  7. 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.

    NOTICE:
    1. Do not race the engine immediately after starting the engine.
    2. After idling the engine, racing the engine is acceptable.

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

      1. The water temperature is 60°C (140°F) or more.
      2. The fuel temperature is 20°C (68°F) or more.
      HINT:
      1. The water temperature can be estimated by touching the outlet hose.
      2. The fuel temperature can be estimated by using the ambient temperature as a substitute.
      3. If the water and fuel temperature is difficult to estimate, use the intelligent tester and enter the following menus: Powertrain / Engine / Data List / Coolant Temp.

  10. Initialization is complete.


When not using intelligent tester

  1. Using SST, connect terminals TC and CG of the DLC3.
