Foreword
ISO (the International Organization for Standardization) is a worldwide federation ofnational 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 commit tee. International
organizations, governmental and non-governmental, in Iiaison 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 ISOjIEC 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 ofthe ISOjIEC Directives, Part 2 (see www.iso.orgjdirectives).
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 ofthe document will be in the Introduction andjor
on the ISO Iist of patent decl arations received (see www.iso.orgjpatents:).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO's adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: .Eoreword - Supplementary jnformation
The committee responsible for this document is ISOjTC 22, Road vehicles, Subcommittee SC 31, Data
communication.
This third edition cancels and replaces the second edition ( I SO 15031-5:2011), which has been
technically revised.
ISO 15031 consists of the following par ts, under the general title Road vehicles - Communication
between vehicle and external equipment for emissions-related diagnostics:
Part 1: General informαtion and use cαse definition
Part 2: Guidance on 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

ISO 15031-5:2015(E)
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 lSO 15031-7 are based on SAE recommended
practices. This part of ISO 15031 is based on SAE }1979.
This International Standard includes the communication between the vehicle's On-8oard Oiagnostic
(080) systems and test equipment implemented across vehicles within the scope of the legislated
emissions-related 080.
To achieve this, it is based on the Open Systems Interconnection (OSI) 8asic Reference Model in
accordance with ISOjIEC 7498-1 and ISOjIEC 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 Ta国ti.
Oiagnostic services (layer 7), specified in the following:
this part ofISO 15031;
ISO 27145-3 (WWH-080).
Presentation layer (layer 的, specified in the following:
ISO 15031-2, SAE J1930-0A;
this part of ISO 15031, SAE J1979-0A;
ISO 15031-6, SAE J2012-0A;
ISO 27145-2, SAE }2012-0A.
Session layer services (layer 町, specified in the following:
ISO 14229-2 supports ISO 15765-4 OoCAN and ISO 14230-4 OoK-Li ne protocols;
ISO 14229-2 is not applicable to the SAE J1850 and ISO 9141-2 protocols.

SAE document reference concept
ISO 15031 references several SAE documents which contain all terms, data, and DTC (diagnostic trouble
code) definitions. This is illustrated in Fi串江豆主.
Additional information on the content of the referenced documents is given below:
SAE }1930: 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 }1979: the document is concerned with the definition of emissions-related diagnostic services
(diagnostic test modes).lt references SAE }1979-DA which contains all standardized data items such
as PIDs, Test IDs, Monitor IDs, and IN FOTYPE lDs.
SAE }2012: the document is concerned with the procedure for defining emissions-related DTCs. It
references SAE }2012-DA which contains all standardized data items such as DTCs and FTBs (failure
type bytes).
