irreversible change or loss of data. An example of this type of message is the “Erase

Error messages display when a system or procedural error has occurred. Examples of
possible errors include cable disconnection or communication interruption.
5.4.3 Making Selections
The Diagnostics application is a menu-driven program that presents a series of choices.
Once a selection has been made, the next menu in the series is displayed. Each
selection narrows the focus and leads to the desired test. Tap the screen to make menu
selections.
5.5 Diagnostic Function Entrance
The Diagnostics application enables a data link to the electronic control system of the
test vehicle for vehicle diagnosis. The application performs function tests, retrieves
vehicle diagnostic information such as trouble codes and live data from various vehicle
control systems like engine, transmission, and ABS.
There are two options available when accessing the diagnostic function:
1. Auto Scan — starts auto scanning for all the available systems on the vehicle.
2. Control Unit — displays a selection menu for all available control units of the test
vehicle.
After a selection is made and the tablet establishes communication with the vehicle, the
corresponding function menu or selection menu will display.
