9.5.1 Screen Messages
Messages display when additional input is needed before proceeding. There are three
main types of on-screen messages: Confirmation, Warning, and Error.
Confirmation Messages
These usually display as an “Information” screen, 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, the message will display only briefly.
Warning Messages
These will display when the selected action may result in an irreversible change or loss of
data. An example of this message is the “Erase Codes” message.
Error Messages
These will display when a systemic or procedural error occurs. Possible errors include
cable disconnection or communication interruption.
9.5.2 Making Selections
The Diagnostics application is a menu-driven program that presents a series of options,
one at a time. As you select from a menu, the next menu in the series will display. Each
selection narrows the focus and leads to the desired test. Use your fingertip to make menu
selections.
9.6 ECU Information
This function retrieves and displays the specific information for the tested control unit,
