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.

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.
