AIR CONDITIONING SYSTEM DATA LIST / ACTIVE TEST

Tech Tips

Using the GTS to read the Data List allows 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. DATA LIST


    1. Connect the GTS to the DLC3.

    2. Turn the power switch ON (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / (desired menu) / Data List.

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

  2. ACTIVE TEST

    Tech Tips

    Using the GTS 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 Test.


    1. Connect the GTS to the DLC3.

    2. Turn the power switch ON (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Air Conditioner / Active Test.

    5. According to the display on the GTS, perform the "Active Test".
