BS ISO 14229-2:2021

This standard BS ISO 14229-2:2021 Road vehicles. Unified diagnostic services (UDS) is classified in these ICS categories:

• 43.180 Diagnostic, maintenance and test equipment

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.
