Scanner
This section describes the basic operation of the Scanner function.
The
Scanner
icon is located on the Home screen.
The Scanner function allows your diagnostic tool to communicate
with the electronic control modules (ECMs) of the vehicle being
serviced. This allows you to perform tests, view diagnostic trouble
codes (DTCs), and live data parameters from various vehicle
systems such as the engine, transmission, antilock brake system (ABS) and more.

6.1 Basic Operation
6.1.1 Scanner Overview
Scanner is a menu driven application that communicates with vehicle control
modules to access diagnostic trouble codes (DTCs), parameter data (PIDs),
functional tests, and more. To navigate the application, use your fingertip or the
control buttons to make onscreen menu selections to access the desired data, test or
function.
Screen messages appear when additional input is needed before proceeding. There
are three types of on-screen messages; confirmations, warnings, and errors.
•
Confirmation Messages
- Confirmation messages inform you when you are
about to perform an action that cannot be reversed or when an action has been
initiated and your confirmation is needed to continue. When a user-response is
not required to continue, the message displays briefly before automatically
disappearing.
•
Warning Messages
- Warning messages inform you when completing the
selected action may result in an irreversible change or loss of data.
•
Error Messages
- Error messages inform you when a system or procedural
error has occurred. Examples of possible errors include a disconnected cable
or a peripheral, such as a printer, is powered off.
