AIR CONDITIONING SYSTEM DATA LIST / ACTIVE TEST

DATA LIST
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.
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Enter the following menus: Body Electrical / Air Conditioner / Data List.
-
Check the value(s) by referring to the table below.

ACTIVE TEST
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 Tests.
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Enter the following menus: Body Electrical / Air Conditioner / Active Test.
-
Check the operation by referring to the table below.
