Toyota CH-R Service Manual: Data List / Active Test




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.


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.

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch ON.

(d) Turn the Techstream on.

(e) Enter the following menus: Body Electrical / Combination Meter / Data List.

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