24、iography391 BS ISO 14229-1:2013ISO 14229-1:2013(E) vi ISO 2013 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 throug
25、h 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 collaborat
26、es 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 Standard
27、s. 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 thi
28、s document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14229-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This second edition cancels and replaces
29、the first edition (ISO 14229-1:2006), which has been technically revised. ISO 14229 consists of the following parts, under the general title Road vehicles Unified diagnostic services (UDS): Part 1: Specification and requirements Part 2: Session layer services Part 3: Unified diagnostic services on C

32、9 has been established in order to define common requirements for diagnostic systems, whatever the serial data link is. To achieve this, ISO 14229 is based on the Open Systems Interconnection (OSI) Basic Reference Model in accordance with ISO 7498-1 and ISO/IEC 10731, which structures communication
33、systems into seven layers. When mapped on this model, the services used by a diagnostic tester (client) and an Electronic Control Unit (ECU, server) are broken into the following layers in accordance with Table 1: Application layer (layer 7), unified diagnostic services specified in ISO 14229-1, ISO

42、1 Scope This part of ISO 14229 specifies data link independent requirements of diagnostic services, which allow a diagnostic tester (client) to control diagnostic functions in an on-vehicle Electronic Control Unit (ECU, server) such as an electronic fuel injection, automatic gear box, anti-lock brak
43、ing system, etc. connected to a serial data link embedded in a road vehicle. It specifies generic services, which allow the diagnostic tester (client) to stop or to resume non-diagnostic message transmission on the data link. This part of ISO 14229 does not apply to non-diagnostic message transmissi
44、on on the vehicles communication data link between two Electronic Control Units. However, this part of ISO 14229 does not restrict an in-vehicle on-board tester (client) implementation in an ECU in order to utilize the diagnostic services on the vehicles communication data link to perform bidirectio
45、nal diagnostic data exchange. This part of ISO 14229 does not specify any implementation requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.
