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 15031-3 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 Road vehicles Communication between vehicle and external equipment for emissions-related diagnostics: Part 1: General information Part 2: 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 15031-3:2004(E) © ISO 2004 All rights reserved v Introduction 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 J1962:02/98, Diagnostic Connector. -,-,- -,-,- INTERNATIONAL STANDARD ISO 15031-3:2004(E) © ISO 2004 All rights reserved 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 communication 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 equipment 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 of 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 allocation, 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 of this document.

It should be recognized that country or regional governments could mandate a connector location which supersedes these provisions. 4.2 Consistency of location 4.2.1 Vehicle connectors Type A 4.2.1.1 Passenger cars and light duty vehicles The connector shall be located in the passenger or drivers compartment in the area bounded by the driver's end of the instrument panel to 300 mm beyond the vehicle centreline, attached to the instrument panel and easy to access from the driver's seat. The preferred location is between the steering column and the vehicle centreline. The vehicle connector shall be mounted to facilitate mating and unmating. 4.2.1.2 Heavy duty vehicles 4.2.1.2.1 Trucks The connector shall be located in the passenger or driver's compartment in the area bounded by the drivers end and the co-driver's end of the instrument panel, including the outer side. It shall be attached to the instrument panel and easy to access from the drivers seat or from the co-driver's seat or from the outside. The vehicle connector shall be mounted to facilitate mating and unmating. 4.2.1.2.2 Buses For left-hand-driven and right-hand-driven buses and coaches without co-driver's seat, the connector shall be located in the area bounded by the driver's end and front passenger door-sided end of the instrument panel, including the outer side or behind the driver in the partition wall, in an area bounded by the driver's compartment, with access from the driver's seat. For left-hand-driven and right-hand-driven buses and coaches with co-driver's seat, the connector shall be located in the area bounded by the driver's end and the co-driver's end of the instrument panel, including the outer side or behind the driver in the partition wall, in an area bounded by the driver's compartment, with access from the driver's seat. 4.2.2 Vehicle connectors Type B 4.2.2.1 Light duty vehicles The connector shall be located in the passenger or driver's compartment in the area bounded by the drivers end and the co-driver's end of the instrument panel, including the outer side, and an imagined line 750 mm beyond the vehicle centreline.
