The D-PDU API (ISO 22900-2) is a standardized, universal programming interface for accessing a Vehicle Communication Interface (VCI).
The use of standardized diagnostic interfaces is becoming more and more important in communication with control units, especially in the field of vehicle diagnostics. With the ISO 22900-2 standard, a universal, powerful diagnostic and communication interface has been established. The standard offers a defined C interface as well as a uniform system integration. In addition, by means of an event-driven interface design a very high application performance can be achieved.
