Data List / Active Test

  1. DATA LIST 

    Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save 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 deciding whether a part is faulty or not.

    1. Warm up the engine.
    2. Turn the engine switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the engine switch on (IG).
    5. Turn the Techstream on.
    6. Enter the following menus:
      1. for Combination Meter: Body Electrical / Combination Meter / Data List.
      2. for ABS/VSC/TRAC: Chassis / ABS/VSC/TRAC / Data List.
      3. for Engine and ECT: Powertrain / Engine and ECT / Data List.
      4. for D-SEAT SW: Body Electrical / D-SEAT SW / Data List.
    7. According to the display on the Techstream, read the Data List.

  2. ACTIVE TEST 

    Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Combination Meter / Active Test.
    5. According to the display on the Techstream, perform the Active Test.
