DATA LIST / ACTIVE TEST
DATA LIST
NOTICE:
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.
HINT:
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.
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus:
(1) for Air Conditioner: Body Electrical / Air Conditioner / Data List.
(2) for Engine: Powertrain / Engine / Data List.
(3) for Rain and/or Humidity Sensor: Body Electrical / Rain and/or Humidity Sensor / Data List.
(e) Read the Data List according to the display on the Techstream.
