ISO 14229-6:2013 specifies the implementation of a common set of unified diagnostic services (UDS) on K-Line (UART based) in road vehicles (UDSonK-Line). UDSonK-Line references ISO 14229 1 and ISO 14229 2, and specifies implementation requirements of the diagnostic services to be used for diagnostic communication over K-Line, the server memory programming for all in-vehicle servers connected to a K-Line network with external test equipment. UDSonK-Line does not specify any requirement for the in-vehicle K-Line bus architecture. ISO 14229-6:2013 makes reference to information contained in ISO 14229 1, ISO 14229 2, ISO 14230 1, and ISO 14230 2. ISO 14229-6:2013 does not include any redundant information of the above-mentioned documents. It focuses on additional requirements specific to the implementation of UDSonK-Line network, and specific restrictions in the implementation of UDSonK-Line network.
