ISO DIS 14229-7

Description / Abstract: This part of ISO 14229 specifies the implementation of a common set of unified diagnostic services (UDS) on UART-based local interconnect networks in road vehicles. The UDSonLIN diagnostics defines methods to implement diagnostic data transfer between a client and the LIN slave nodes via the LIN master node.

LIN slave nodes support three different diagnostic classes as defined in ISO 17987.

UDSonLIN references part°1 and part°2 of ISO 14229 and specifies implementation requirements of

—the diagnostic services to be used for diagnostic communication over LIN,

—the server memory programming for in-vehicle LIN servers with an external test equipment,

—the configuration of a LIN slave node as specified in ISO 17987.

NOTE UDSonLIN does not specify any requirement for the in-vehicle LIN bus architecture.

This part of ISO 14229 makes reference to information contained in

— ISO 14229-1, Road vehicles — Unified diagnostic services (UDS) — Part 1: Specification and requirements;

— ISO 14229-2, Road vehicles — Unified diagnostic services (UDS) — Part 2: Session layer services;

— ISO 17987 (all parts), Road vehicles — Local interconnect network (LIN);

This part of ISO 14229 does not include any redundant information of the above mentioned documents. It focuses on

— additional requirements specific to the implementation of UDSonLIN network, and

— specific restrictions in the implementation of UDSonLIN network.
