Toyota 4Runner: Data List / Active Test




In the table below, the valves listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.


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 ignition switch to ON.

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Telematics / Data List.

(e) According to the display on the Techstream, read the "Data List".
