Data List / Active Test

  1. READ DATA LIST 

    HINT:

    Using the Techstream's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting in one way to save time.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch ON (IG).
    3. Turn the Techstream on.
    4. Read the DATA LIST according to the display on the tester.

  2. PERFORM ACTIVE TEST 

    HINT:

    Performing the Techstream's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time.

    The DATA LIST can be displayed during the ACTIVE TEST.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch ON (READY).
    3. Perform the ACTIVE TEST according to the display on the tester.
