Data List/Active Test

  1. DATA LIST 

    HINT:

    By referring to the Data List displayed on Techstream, you can read the value and status of parts such as 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.

    1. Connect Techstream to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. Turn Techstream.
    4. From the display on the tester, read the "Data List".

  2. ACTIVE TEST 

    HINT:

    Performing the Active Test using Techstream allows the relay, actuator and so on to operate without parts removal. Performing the Active Test as the first step of troubleshooting is one of the methods to shorten labor time.

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

    1. Connect Techstream to the DLC3.
    2. Turn the ignition switch to the ON position.
    3. Turn Techstream ON.
    4. According to the display on the tester, perform the "Active Test".

      HINT:

      Ignition switch must be turned to the ON position to proceed to the  2Active Test using Techstream.
