10、010(E) iv ISO 2010 All rights reservedForeword 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
11、 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 Electrotec
12、hnical 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
13、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 righ
14、ts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15031-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This second edition cancels and replaces the first edition (ISO 15031-1:2001), which
15、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, abbreviat
16、ions 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 provides an implementer with all docume
17、nts and references required to support the implementation of legislated on-board diagnostics (OBDs) in accordance with the requirements set forth in the country-specific emissions regulation. ISO 15031-1 provides general information and use case definitions and an overview of the document set along
18、with the use case definitions and a common set of resources (definitions, references) for use by all subsequent parts. ISO 15031-2 is a guide to terms, definitions, abbreviations and acronyms used in emissions-related diagnostics, with respect to the communication between road vehicles and external
19、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 15031-1:2010(E) ISO
20、 2010 All rights reserved v ISO 15031-3 specifies a minimum set of requirements for a diagnostic connector used in communication between vehicle and external equipment for emissions-related diagnostics. ISO 15031-4 provides requirements to be fulfilled by any external test equipment connected to the
21、 vehicle. ISO 15031-5 provides the data reporting requirements of (OBD) regulations in the United States and Europe, and any other region that may adopt similar requirements in the future. ISO 15031-5 specifies: message formats for request and response messages, timing requirements between request m
22、essages from external test equipment and response messages from vehicles, and between those messages and subsequent request messages, behaviour of both the vehicle and external test equipment if data is not available, a set of diagnostic services, with corresponding content of request and response m
23、essages, to satisfy OBD regulations. ISO 15031-6 provides uniformity for standardized Diagnostic Trouble Codes (DTC) that electrical/electronic (OBD) systems of motor vehicles are required to report when malfunctions are detected. It further provides guidance for uniform messages (text descriptor) a
24、ssociated with these codes. ISO 15031-7 specifies a standard mechanism for limiting access to particular vehicle services (such as those intended for use only within the original manufacturing plant). ISO 15031-1:2010(E) vi ISO 2010 All rights reservedIntroduction 0.1 Overview ISO 15031 consists of
25、a number of parts which, taken together, provide a coherent, self-consistent set of specifications to facilitate emissions-related diagnostics. Parts 2 through 7 are based on SAE recommended practices. This part of ISO 15031 provides an introduction to the series of International Standards and the r
26、eference to the SAE Digital Annexes (DA). Such standardization is of benefit to many sectors of the automotive industry, including service technicians who are required to work on a variety of vehicle types and component suppliers who wish to provide similar products to several vehicle manufacturers.
27、 Some of the documents have a wider scope than just purely emissions-related issues. The legislator is the adequate authority to make the appropriate references. ISO 15031 includes the communication between the vehicles on-board diagnostic (OBD) systems and an external (off-board) “generic” test equ
28、ipment within the scope of the emissions-related OBD legislation. 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
29、 services specified by ISO 15031 are broken into the following layers in accordance with Table 1: diagnostic services (layer 7), specified in ISO 15031-5 (emissions-related OBD); ISO 27145-3 (WWH-OBD); presentation layer (layer 6), specified in ISO 15031-2, SAE J1930-DA; ISO 15031-5, SAE J1979-DA; I
