DATA LIST / ACTIVE TEST

1. DATA LIST

HINT:

Using the Techstream to read the Data List allows 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 ON.

c. Turn the tester on.

d. Enter the following menus:

Select: Body Electrical / Sliding Roof / Data List.

e. According to the display on tester, read the "Data List".

2. ACTIVE TEST

HINT:

Using the Techstream to perform Active Test allows relays, VSVs, actuators and other items to be
operated without removing any parts. This non-intrusive functional inspection can be very useful because
intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Test early
in troubleshooting is one way to save diagnostic time. Data List information can be displayed while
performing Active Test.
