8.4 Diagnosis
The Diagnostics application enables a data link to the electronic control
system of the test vehicle for vehicle diagnosis or service. The application
performs functional tests, retrieves vehicle diagnostic information such as
trouble and event codes and live data from various vehicle control systems
such as engine, transmission, ABS, and more.
There are two options available when accessing the Diagnosis section:
⚫ Auto Scan – starts auto scanning for all the available systems on the test
vehicle.
⚫ Control Units – displays a selection menu of all available control units on
the test vehicle.
After a section is made and the tablet establishes communication with the
vehicle, the corresponding function menu or selection menu displays.
8.4.1 Auto Scan
The Auto Scan function performs a comprehensive scanning of all the
systems on the vehicle's ECU to locate systems faults and retrieve DTCs. An
example of the Auto Scan interface is pictured below.
