This part of ISO 14229 specifies data link independent requirements of session layer services.
This part of ISO 14229 specifies common session layer services to provide independence between unified diagnostic services (ISO 14229-1) and all transport protocols and network layer services (e.g. ISO 15765-2 DoCAN, ISO 10681-2 Communication on FlexRay, ISO 13400 DoIP, ISO 14230-2 DoK-Line, etc.)
This part of ISO 14229 specifies a common service primitive
interface between OSI layer 4 (Transport) and layer 5 (Session) via
so-called service request/confirmation
ISO 15031 (emissions-related OBD) and ISO 27145 (WWH-OBD) support the standardized service primitive interface.
