scope:

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.
