Road vehicles — Communication between vehicle and external equipment for emissions-related diagnostics — Part 2: Guidance on terms, definitions, abbreviations and acronyms
ISO 15031-2:2010 provides guidance on the usage of terms, definitions, abbreviations and acronyms used in emissions-related diagnostics, with respect to the communication between road vehicles and external equipment used in that field. It also specifies a procedure for constructing new terms. As it gives recommended usage of diagnostic terms applicable to electrical/electronic systems, it also makes reference to related mechanical terms, definitions, abbreviations and acronyms. ISO 15031-2:2010 is applicable to all light-duty gasoline and diesel passenger vehicles and trucks, and to heavy-duty gasoline vehicles. Specific applications of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair databases, underhood emission labels and emission certification applications. ISO 15031-2:2010 is intended to help industry provide standard terms, definitions, abbreviations and acronyms with a view to establishing a common terminology for diagnostic tools and publications.

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 15031-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
This first edition of ISO 15031-2 cancels and replaces ISO/TR 15031-2:2004, which has been technically
revised.
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 and use case 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

Introduction
0.1 Overview
The various parts of ISO 15031, when taken together, provide a coherent, consistent set of specifications for
facilitating emissions-related diagnostics. ISO 15031-2 to ISO 15031-7 are based on recommended practices
of the Society of Automotive Engineers (SAE). This part of ISO 15031 is based on SAE J1930.
See ISO 15031-1 for general information and an introduction to ISO 15031.
As the number of sophisticated electrical and electronic (E/E) systems on motor vehicles has increased, the
number of terms, abbreviations and acronyms which describe various components of these systems has
increased enormously.
The nomenclature used to convey automotive service information is being standardized in order to more
accurately convey information to technicians faced with the diagnosis and repair of increasingly complex
vehicles.
To be properly descriptive, each type of automotive nomenclature requires a consistent methodology. This
document is concerned with a methodology for naming objects and systems and with the set of words from
which names are built.
⎯ The procedure allows the complete description of objects and systems without ambiguity and the
generation of names which distinguish among similar objects or systems without confusion but with
brevity.
⎯ Using terms which are well defined within the context of the automotive service industry, the procedure
allows already existing, imprecise, names to be suitably changed and future names to be assigned in a
predictable way that will reliably convey meaning to the technician.
0.2 SAE document reference concept
This part of ISO 15031 references several SAE documents which contain all the terms, data and diagnostic
trouble code (DTC) definitions.
This is illustrated in Figure 1. Additional information on the content of the referenced documents is given
below.
⎯ 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
failure type bytes (FTBs).

Key
1 SAE Digital Annexes
Figure 1 — SAE Digital Annex document reference
0.3 SAE J1930-DA Digital Annex
This part of ISO 15031 references the SAE J1930-DA. The SAE J1930-DA is concerned with the terms,
abbreviations and acronyms which are defined according to the procedure for naming objects and systems.
The SAE J1930-DA includes several appendices:
⎯ Approved terms;
⎯ SAE J1979 parameter ID (PID) acronyms;
⎯ Glossary and Control Module Naming;
⎯ Figures to assist in the identification of the proper terms;
⎯ Historical reference for acronym usage in previous publications.
0.4 SAE Digital Annex revision procedure
New emissions-related regulatory requirements drive new in-vehicle technology to lower emissions. New
technology-related OBD (on-board diagnostic) monitor data and diagnostic trouble codes need to be
standardized to support the external (off-board) “generic” test equipment. All relevant information is proposed
by the automotive industry represented by members of the appropriate SAE task force.

Part 2:
Guidance on terms, definitions, abbreviations and acronyms
1 Scope
This part of ISO 15031 provides guidance on the usage of terms, definitions, abbreviations and acronyms
used in emissions-related diagnostics, with respect to the communication between road vehicles and external
equipment used in that field. It also specifies a procedure for constructing new terms. As it gives
recommended usage of diagnostic terms applicable to electrical/electronic systems, it also makes reference to
related mechanical terms, definitions, abbreviations and acronyms.
This part of ISO 15031 is applicable to all light-duty gasoline and diesel passenger vehicles and trucks, and to
heavy-duty gasoline vehicles. Specific applications of this document include diagnostic, service and repair
manuals, bulletins and updates, training manuals, repair databases, underhood emission labels and emission
certification applications.
The introduction of a term, abbreviation or acronym not covered by this part of ISO 15031 is not prohibited.
This part of ISO 15031 is intended to help industry provide standard terms, definitions, abbreviations and
acronyms with a view to establishing a common terminology for diagnostic tools and publications.
This part of ISO 15031 references the SAE J1930-Digital Annex (DA), which includes all standard terms,
definitions, abbreviations and acronyms.

4 General information
Certain terms have already been in common use and are readily understood by manufacturers and
technicians, but do not strictly follow the methodology of this document. The SAE J1930 committee may
approve these terms that are already considered industry standard. These terms fall into three categories:
a) acronyms that do not logically fit the term;
b) acronyms existing at the component level, i.e. their terms contain the base word or noun that describes
the generic item that is being further defined;
c) acronyms for terms that appear to contain the base word, but are frequently used as a modifier to another
base word. This use may possibly be thought of as following the methodology since the acronym is
normally used as a modifier.
