Road vehicles -- Communication between vehicle and external equipment for emissions-related diagnostics

ISO 15031-3:2016 references the latest publication of SAE J1962. On-board diagnostic (OBD) regulations require road vehicles to be equipped with a standardized connector for purposes of access to OBD information by ISO 15031‑4 compliant external test equipment. This part of ISO 15031 describes the requirements for the physical connection and associated pin usage to allow for standard access to the OBD data. The first edition of this part of ISO 15031 was based on SAE J1962 and was intended to meet European OBD requirements for 2000 and later model year vehicles, and added a modified connector type to accommodate vehicles with a 24 V system. This revised part of ISO 15031 is technically equivalent to SAE J1962 with the exception of the specific requirements identified in the document. ISO 15031-3:2016 specifies additional requirements related to right hand driven (RHD) vehicles. Annex A and Annex B are for information and not required to fulfil emissions-related OBD.

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).

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. 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 J1962 (Diagnostic connector).

ISO 15031 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 7498-1 and ISO/IEC 10731, which structures communication systems into

seven layers. When mapped on this model, the services specified by ISO 15031 are broken into the

following 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:
— DoCAN: ISO 15765-2 Transport protocol and network layer services;
— SAE J1850: ISO 15031-5 Emissions-related diagn
