ISO 14229-7:2015

Road vehicles — Unified diagnostic services (UDS) — Part 7: UDS on local interconnect network (UDSonLIN)

ISO 14229-7:2015 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 through the LIN master node. LIN slave nodes support three different diagnostic classes as defined in ISO 17987. UDSonLIN references ISO 14229-1 and ISO 14229-2 and specifies implementation requirements of the following: - diagnostic services to be used for diagnostic communication over LIN, - server memory programming for in-vehicle LIN servers with an external test equipment, and - configuration of a LIN slave node as specified in ISO 17987.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

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 UART-based local interconnect networks (UDSonLIN).
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 the following.
— Application layer (layer 7), unified diagnostic services specified in ISO 14229-1, ISO 14229-3
UDSonCAN, ISO 14229-4 UDSonFR, ISO 14229-5 UDSonIP, ISO 14229-6 UDSonK-Line, ISO 14229-7
UDSonLIN, further standards, and ISO 27145-3 WWH-OBD.
— Presentation layer (layer 6), vehicle manufacturer specific, ISO°27145-2 WWH-OBD.
— Session layer services (layer 5) specified in ISO 14229-2.
— Transport layer services (layer 4), specified in ISO 15765-2 DoCAN, ISO 10681-2 Communication on
FlexRay, ISO 13400-2 DoIP, ISO 17987-2 LIN, ISO 27145-4 WWH-OBD.
— Network layer services (layer 3), specified in ISO 15765-2 DoCAN, ISO 10681-2 Communication on
FlexRay, ISO 13400-2 DoIP, ISO 17987-2 LIN, ISO 27145-4 WWH-OBD.
— Data link layer (layer 2), specified in ISO 11898-1, ISO 11898-2, ISO 17458-2, ISO 13400-3, IEEE 802.3,
ISO 14230-2, ISO 17987-3 LIN and further standards, ISO 27145-4 WWH-OBD.
— Physical layer (layer 1), specified in ISO 11898-1, ISO 11898-2, ISO 17458-4, ISO 13400-3, IEEE 802.3,
ISO 14230-1, ISO 17987-4 LIN and further standards, ISO 27145-4 WWH-OBD.
These services should be in accordance with Table 1.
