BS ISO 22900-2:2009 Road vehicles. Modular vehicle communication interface (MVCI). Diagnostic protocol data unit application programming interface (D-PDU API)
BS ISO 22900-2 specifies the diagnostic protocol data unit application programming interface
(D-PDU API) as a modular vehicle communication interface (MVCI) protocol module software interface and common basis for diagnostic and reprogramming software applications.
BS ISO 22900-2 covers the descriptions of the application programming interface (API) functions and the abstraction of diagnostic protocols, as well as the handling and description of MVCI protocol module features. Sample MVCI module description files are also included in BS ISO 22900-2..
Migration from and to the existing standards SAE J2534-1 and RP1210a is addressed. BS ISO 22900-2 also contains a description of how to convert between the APIs. Corresponding wrapper APIs are included.
The purpose of BS ISO 22900-2 is to ensure that diagnostic and reprogramming applications from any vehicle or tool manufacturer can operate on a common software interface, and can easily exchange MVCI protocol module implementations.
