Nice! OBD2TOOL just managed to make VA55054 recognize ODI5 2.0 software and detect driver. Put it here for sharing.
The Way To Use VAS5054A:
1.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.
2.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.
VAS 5054A has a rather long title: VW Bluetooth VA5 5054a ODIS interface with OKI chip supporting UDS protocol. Bluetooth is easy to understand. What the ODIS, OKI chip and UDS protocol stands for respectively?
1)VAS 5054a ODIS
ODIS, short form of Offboard Diagnostic Information System, is the newest software, the replacement of VAS-PC software of VA5 5054a. VAS 5054a is the name of hardware. With the ODIS, vas 5054a odis is able to carry out powerful function, like read error codes, clear fault codes, display live data etc.
ODIS Computer requirement:Windows XP (SP2/SP3 operating system)
2)OKI chip
Why do we need this chip and what the difference between VAS 5054a with KIO chip and v/ithour OKI chip? OKI chip is designed to be used for SAE J1850 PMW protocol and UDS protocol. Some people may argue that OKI chip is useless for VAG group, but for Ford PWM/VPW protocols it plays an important role. If you need not need OKI chip, you can still choose VAS 5054 without OKI chip.
3)UDS Protocol
UDS is the short form of Unified Diagnostic Services. The ISO 15765 UD5 Blockset provides a MotoHawk application with an interface to a PC-based diagnostics application or a scan tool.
ISO 15765 is the specification for the CAN transport layer for Unified Diagnostic Services (UDS) and also legislated On Board Diagnostics (OBD) protocol as found in ISO 15031. UDS is an ISO standard which can be found in ISO 14229. vas 5054a oki chip is a common way to add OBD and provides the MotoHawk application with the capability of reporting self-diagnostics and trending information. The IS015765 block set by themselves do not provide diagnostics. It is the application logic which must be designed with the diagnostic capabilities and the mechanism for reporting the diagnostic information via a standardized protocol is through the use of these blocks.
