12、0 ISO 15031-3:2004(E) iv ISO 2004 All rights reserved 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.
13、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 Internat
14、ional 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 Stand
15、ards 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 subjec
16、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15031-3 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 15031 consists of the following parts, under the general title Ro

20、erved 1 Road vehicles Communication between vehicle and external equipment for emissions-related diagnostics Part 3: Diagnostic connector and related electrical circuits, specification and use 1 Scope This part of ISO 15031 specifies a minimum set of requirements for a diagnostic connector used in c
21、ommunication between vehicle and external equipment for emissions-related diagnostics. Its aim is to promote the use of a common diagnostic connector throughout the motor vehicle industry. The diagnostic connection consists of two mating connectors, the vehicle connector and the external test equipm
22、ent connector. Applicable to all types of road vehicles, the connector specified has no positive locking feature and is intended for short-term diagnostic connection only. This part of ISO 15031 specifies functional requirements for a) the vehicle connector, separated into the four principal areas o
23、f 1) connector location/access, 2) connector design, 3) connector contact allocation, and 4) electrical requirements for connector and related electrical circuits, and b) the external test equipment connector, separated into the three principal areas of 1) connector design, 2) connector contact allo
24、cation, and 3) electrical requirements for connector and related electrical circuits. The dimensional requirements of the vehicle connector are given as a minimum specification, to allow design freedom. 2 Normative references The following referenced documents are indispensable for the application o
