SFI SYSTEM (w/o Secondary Air Injection System) DATA LIST / ACTIVE TEST


  1. 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 Condition" are reference values. Do not depend solely on these reference values when determining whether or not a part is faulty.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect an intelligent tester to the DLC3.

    4. Turn the ignition switch to the ON position.

    5. Turn the intelligent tester ON.

    6. Select the following menu items: Powertrain / Engine and ECT / Data List.

  2. ACTIVE TEST

    Tech Tips

    Performing an Active Test using the intelligent tester enables components including the relay, VSV, and actuator to be operated without removing any parts. Performing the Active Test as the first step of troubleshooting is one method of shortening diagnostic time.

    Data List is displayed during an Active Test.


    1. Warm up the engine.

    2. Turn the ignition switch to OFF.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to the ON position.

    5. Turn the intelligent tester ON.

    6. Select the following menu items: Powertrain / Engine and ECT / Active Test.

    7. Perform the Active Test by referring to the table below.
