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) 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 / Pre-Collision 2 / Data List.
(e) Read the Data List according to the display on the Techstream.

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.
