1. READ DATA LIST

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. Turn the ignition switch OFF.

b. Connect the Techstream to the DLC3.

c. Turn the ignition switch to ON and the Techstream on.

d. Enter the following menu items: Chassis/Tire Pressure Monitor/Data List.

e. Check the values by referring to the table below.

NOTE:

In the table below, the values listed under "Normal Condition" are
