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
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 31, Data
This third edition cancels and replaces the second edition (ISO 15031-6:2010), which has been
technically revised.

Introduction
Overview
ISO 15031 consists of a number of parts which, taken together, provide a coherent self-consistent set of
specifications to facilitate emissions-related diagnostics. ISO 15031-1 provides an introduction to the
series of International Standards. ISO 15031-2 through ISO 15031-7 are based on SAE recommended
practices. This part of ISO 15031 is based on SAE J2012 (Diagnostic Trouble Code Definitions).
This International Standard includes the communication between the vehicle’s On-Board Diagnostic
(OBD) systems and test equipment implemented across vehicles within the scope of the legislated
emissions-related OBD.
To achieve this, it 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. When mapped on this model, the services specified by this International Standard are broken
into the following layers in accordance with Table 1.
— Diagnostic services (layer 7), specified in the following:
— ISO 15031-5 (emissions-related OBD);
— ISO 27145-3 (WWH-OBD).
— Presentation layer (layer 6), specified in the following:
— ISO 15031-2, SAE J1930-DA;
— ISO 15031-5, SAE J1979-DA;
— ISO 15031-6, SAE J2012-DA (OBD);
— ISO 27145-2, SAE J2012-DA (WWH-OBD).
— Session layer services (layer 5), specified in the following:
— ISO 14229-2 supports ISO 15765-4 DoCAN and ISO 14230-4 DoK-Line protocols;
— ISO 14229-2 is not applicable to the SAE J1850 and ISO 9141-2 protocols.
— Transport layer services (layer 4), specified in the following:
— ISO 15765-2 Transport protocol and network layer services;
— SAE J1850 defined in ISO 15031-5 Emissions-related diagnostic services;
— ISO 9141-2 defined in ISO 15031-5 Emissions-related diagnostic services;
— ISO 14230-4 defined in ISO 15031-5 Emissions-related diagnostic services.
— Network layer services (layer 3), specified in the following:
— ISO 15765-2 Transport protocol and network layer services;
— SAE J1850 defined in ISO 15031-5 Emissions-related diagnostic services;
— ISO 9141-2 defined in ISO 15031-5 Emissions-related diagnostic services;
— ISO 14230-4 defined in ISO 15031-5 Emissions-related diagnostic services.
— Data link layer (layer 2), specified in the following:
— ISO 15765-4, ISO 11898-1, ISO 11898−2;

ISO 15031 references several SAE documents which contain all terms, data, and DTC definitions.
See Figure 1 with the following definition of content in this International Standard.
— SAE J1930: the document is concerned with a procedure for naming objects and systems and
with the set of words from which names are built. It references SAE J1930-DA which contains all
standardized naming objects, terms, and abbreviations.
— SAE J1979: the document is concerned with the definition of emissions-related diagnostic services
(diagnostic test modes). It references SAE J1979-DA which contains all standardized data items like
PIDs, test IDs, monitor IDs, and InfoType IDs.
— SAE J2012: the document is concerned with the procedure for defining emissions-related diagnostic
trouble codes. It references SAE J2012-DA which contains all standardized data items like DTCs and
FTBs.
