Making Selections
The Diagnostics application is a menu driven program that presents a series of choices
one at a time. As you select from a menu, the next menu in the series displays. Each
selection narrows the focus and leads to the desired test. Use your fingertip or the
stylus pen to make menu selections.
Main Menu
The Diagnostics application allows you to establish a data link to the electronic control
system of the test vehicle via the VCI device for vehicle diagnosis, service or
programming. You can operate functional tests, retrieve vehicle diagnostic information
such as trouble codes, event codes and live data, and perform ECU reprogramming, for
various vehicle control systems, such as engine, transmission, ABS and more.
The Vehicle Diagnostics screen (Figure 4-3) has three main options:
1. Diagnosis – a comprehensive section which includes all available functions:
reading, clearing, saving and printing diagnostic information, as well as performing
active tests and special functions.
2. Service – a separate section designed to perform vehicle scheduled service and
maintenance, such as to reset the service lights and perform calibration for various
systems.
3. Programming/Coding – a separate section designed for quick access to ECU
reprogramming operations.
After a section is selected and the tablet establishes communication with the vehicle via
the VCI device, the corresponding function menu or selection menu displays.
