AIR CONDITIONING SYSTEM DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    Using the GTS 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. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS ON.

    4. Enter the following menus:


      • Select: Body Electrical / Air Conditioner / Data List.

      • Select: Powertrain / Engine and ECT / Data List.

    5. According to the display on GTS, read the "Data List".

  2. PERFORM ACTIVE TEST

    Tech Tips

    Performing the Active Test enables components including relay, VSV (Vacuum Switching Value), actuators and other items to be operated without removing any parts. The Active Test can be performed with an GTS. Performing an Active test as the first step in troubleshooting is one method of shortening diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus:
