Screen Messages
Screen messages appear when additional input is needed before proceeding.
There are three main types of on-screen messages: Confirmation, Warning,
and Error.
Confirmation Messages
This type of messages usually displays as an “Information” screen that
informs 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.
Warning Messages
This type of messages displays a warning that a selected action may result
in an irreversible change or loss of data. The typical example of this is the
“Erase Codes” message.
Error Messages
Error messages display when a system or procedural error has occurred.
Examples of possible errors include a disconnection or communication
interruption.
Making Selections
The Diagnostics application is a menu driven program that presents a series
of choices. As a selection is made, the next menu in the series displays. Each
selection narrows the focus and leads to the desired test. Tap the screen to
make menu selections.
Diagnosis
The Diagnostics application enables a data link to the electronic control
system of the test vehicle for vehicle diagnosis. The application performs
functional tests, retrieves vehicle diagnostic information such as trouble and
event codes and live data for various vehicle control systems, such as engine,
transmission, and ABS.
