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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 15031-5 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronical equipment.
ISO 15031 consists of the following parts, under the general title Road vehicles — Communication between
vehicle and external equipment for emissions-related diagnostics:
⎯ Part 1: General information
⎯ Part 2: Terms, definitions, abbreviations and acronyms
⎯ Part 3: Diagnostic connector and related electrical circuits, specification and use
⎯ Part 4: External test equipment
⎯ Part 5: Emissions-related diagnostic services
⎯ Part 6: Diagnostic trouble code definitions
⎯ Part 7: Data link security

Introduction
ISO 15031 consists of a number of parts which, taken together, provide a coherent self-consistent set of
specifications to facilitate emissions-related diagnostics. Parts 2 through 7 are based on SAE recommended
practices. This part is based on SAE J1979 SEP97 (E/E Diagnostic Test Modes).
ISO 15031-1 provides an introduction to the series of International Standards.
This part of ISO 15031 is based on the Open Systems Interconnection (OSI) Basic Reference Model in
accordance with ISO/IEC 7498 and ISO/IEC 10731, which structures communication systems into seven
layers as shown in the table below.
