Road vehicles — Unified diagnostic services (UDS) — Part 6: Unified diagnostic services on K-Line implementation (UDSonK-Line)

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.

Introduction
This part of ISO 14229 has been established in order to enable the implementation of unified diagnostic
services, as specified in ISO 14229-1, on K-Line (UART based) networks (UDSonK-Line).
To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in
ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When
mapped on this model, the services specified by ISO 14229 are divided into:
— Application layer (layer 7), specified in:
— Vehicle manufacturer enhanced diagnostics: ISO 14229-1 / ISO 14229-6,
— Legislated OBD: ISO°15031-5,
— Legislated WWH-OBD: ISO 14229-1, ISO 27145-3;

Spreadsheet (SPNs), SAE J1939-73:2010, Appendix A (FMIs), SAE J1979-DA and SAE J2012-DA;
— Session layer services (layer 5), specified in:
— Vehicle manufacturer enhanced diagnostics: ISO 14229-2,
— Legislated OBD: ISO 14229-2,
— Legislated WWH-OBD: ISO 14229-2;
— Transport layer services (layer 4), specified in:
— Vehicle manufacturer enhanced diagnostics: ISO 14230-2,
— Legislated OBD: ISO 15765-2, ISO 15765-4,
— Legislated WWH-OBD: ISO 27145-4;
— Network layer services (layer 3), specified in:
— Vehicle manufacturer enhanced diagnostics: ISO 14230-2,
— Legislated OBD: ISO 15765-2, ISO 15765-4,
— Legislated WWH-OBD: ISO 27145-4;
— Data link layer (layer 2), specified in:
