Toyota Tundra. Manual — part 2567

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. Warm up the engine.

b. Turn the ignition switch OFF.

c. Connect the Techstream to the DLC3.

d. Turn the ignition switch ON.

e. Turn the Techstream on.

f. Enter the following menus: Body Electrical/SRS Airbag/Data List.

g. According to the display on the Techstream, read the "Data List".
