4.4 Diagnosis
The Diagnostics application enables a data link to the electronic control system of the
test vehicle for vehicle diagnosis. The application performs functional tests, retrieves
vehicle diagnostics information such as trouble and event codes and live data for various
vehicle control systems, such as engine, transmission, and ABS.
There are two options available when accessing the Diagnosis section:
1. Auto Scan
— starts auto scanning for all the available systems on the vehicle.
2. Control Unit
— displays a selection menu of all the available control units of the test
vehicle.
After a section is made and the tablet establishes communication with the vehicle, the
corresponding function menu or selection menu displays.
4.4.1 Auto Scan
The Auto Scan function performs a comprehensive scanning over all the ECUs in the
vehicle to locate faults and retrieve DTCs.
