11、orewordISO (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 tec
12、hnical 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 o
13、f 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
14、 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.

20、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
21、connector).ISO 15031 includes the communication between the vehicles 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
22、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
23、-5 (emissions-related OBD); ISO 27145-3 (WWH-OBD).

31、al equipment for emissions-related diagnostics Part 3: Diagnostic connector and related electrical circuits: Specification and use1 ScopeThis part of ISO 15031 references the latest publication of SAE J1962.On-board diagnostic (OBD) regulations require road vehicles to be equipped with a standardize
32、d 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
33、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 requi
34、rements identified in the document.This part of ISO 15031 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.2 Normative referencesThe following documents, in whole or in part, are nor
35、matively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
