The VAS 5054A is a universal diagnostic interface for the vehicles of the V olkswagen Group and all OBD vehicle
systems from other manufacturers.
The integrated Bluetooth interface connects the vehicle with a notebook, desktop PC or test system.
No cables are needed for vehicle diagnostics using the VAS 5054A.
The range of the wireless Bluetooth connection is 5 to 10 meters, depending on the environment and the
type of Bluetooth adapter used on the PC side. The Serial Port Profile (SPP) is used for data transfer via
Bluetooth. Different Bluetooth security levels are supported.
The following vehicle bus systems are supported:
?K line (ISO9141-2)
?High-speed CAN (ISO 11898-2)
?Low-speed CAN (ISO 11898-3)
?J1850 (SAE J1850)
The vehicle protocols are handled directly in the VAS 5054A.
This ensures fast response times and a reliable real-time behavior independently of the
PC operating system. Every time a connection is established, the VAS 5054A software is
synchonized with the version installed on the application PC. The VAS 5054A thus automatically
adopts any new features provided after a new software version has been installed on the application PC.
The diagnostic application and the associated Diagnostic Base System are installed on the application PC.
The Diagnostic Base System can access the VAS 5054A via Bluetooth or USB.
Access via Bluetooth:
After a connection to the VAS 5054A has been set up, the Bluetooth software provides a virtual serial COM port
(Bluetooth Serial Port Profile). The Diagnostic Base System uses this COM port to communicate with the VAS 5054A.
You need to specify this port when you install the diagnostic application.
Access via USB: You can also connect the VAS 5054A to the application PC by using the supplied USB cable.
Windows detects the VAS 5054A through Plug and Play, and automatically installs the drivers copied when you
installed the diagnostic application. Setup of the VAS 5054A is then complete and the device is ready for use
by the diagnostic application.
