СИСТЕМА ECD РЕЖИМЫ DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    By reading the Data List displayed on the intelligent tester, you can check values, including those of the switches, sensors, and actuators, without removing any parts. Reading the Data List as the first step of troubleshooting is one method of shortening diagnostic time.

    Note

    In the table below, the values listed under Normal Conditions are for reference only. Do not depend solely on these values when determining whether or not a part is faulty.


    1. Warm up the engine.

    2. Turn the ignition switch OFF.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch ON.

    5. Turn the intelligent tester ON.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List.

    7. Check the values by referring to the following table.

    Performing the Active Test enables components, including the relays, VSV (Vacuum Switching Valve), and actuators, to be operated without removing any parts. The Active Test can be performed with the intelligent tester. Performing the Active Test as a first step of troubleshooting is one method of shortening diagnostic time.

    The Data List can be displayed during Active Tests.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON.

    3. Turn the intelligent tester ON.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

    5. Perform the Active Tests by referring to the following table.
