4.5 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 4-2) 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
NOTE: The accompanied Bluetooth Diagnostic Interface does not support the
ECU programming function. Autel’s J2534 ECU programming device is the
ideal device to perform this function, which is available for your choice.
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.

DTCs. The sample operation interface of Auto Scan displays as below:
