Scan Tool User Guide 1
1: General Information
Introduction
The scan tool is an easy-to-use tool for reading infor-
mation from a vehicle’s electronic control units.
With the tool properly connected to a vehicle’s data
link connector (DLC), you can use the tool to read
diagnostic trouble codes and view “live” data read-
ings from the vehicle’s ECUs. You can save “record-
ings” of the data readings, print information, and
perform special device control tests on the vehicle.

In addition, you can use the scan tool to look up
special repair information and instructions without
being connected to a vehicle.
When you turn the scan tool on, the Application
Manager screen displays icons (or a menu) for
selecting the software applications in the scan
tool as shown and described below.
NOTE: You can change the screen to display either icons
or a menu as shown below. For details, refer to User Inter-
face Selection on page 80.
