Road vehicles — Unified diagnostic services (UDS) — Part 2: Session layer services

Summary

This document specifies common session layer services and requirements to provide independence
between unified diagnostic services (ISO 14229-1) and all transport protocols and network layer
services (e.g. ISO 13400-2 DoIP, ISO 15765-2 DoCAN, ISO 10681-2 communication on FlexRay, ISO 14230-
2 DoK-Line, and ISO 20794-3 CXPI).
This document specifies a common service primitive interface between OSI layer 5 (session) and layer 4
(transport) via so-called service request/indication/confirmation primitives.
