Data List / Active Test

  1. DATA LIST 

    HINT:

    Using Techstream Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor time.

    NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
    1. Warm up the engine.
    2. Turn the engine switch off.
    3. Connect Techstream together to the DLC3.
    4. Turn the engine switch on (IG).
    5. Turn on the tester.
    6. Select the item "Powertrain / E-ACM / Data List".
    7. According to the display on the tester, read the "Data List".

  2. ACTIVE TEST 

    HINT:

    Performing the Active Test using Techstream allows the actuator and so on to operate without parts removal.

    Performing the Active Test as the first step in troubleshooting is one method to shorten labor time.

    It is possible to display the Data List during the Active Test.

    1. Warm up the engine.
    2. Turn the engine switch off.
    3. Connect Techstream to the DLC3.
    4. Turn the engine switch on (IG).
    5. Push the "ON" button of Techstream.
    6. Select the item "Powertrain / E-ACM / Active Test".
    7. According to the display on the tester, perform the "Active Test".
