The work of preparing International Standards is normally carried out through ISO technical commit
13、tees. 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 In
14、ternational 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 S
15、tandards 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 sub

41、Part 3: Common message dictionary1 ScopeThis part of ISO 27145 defines the implementation of a subset of unified diagnostic services (UDS) specified in ISO 14229-1. The diagnostic services are used to communicate the diagnostic data defined in ISO 27145-2.The subset of unified diagnostic services de
42、rives from the requirements stated in the WWH-OBD GTR (Global technical regulation No. 5; see Reference 17). The common message set defined in this part of ISO 27145 is independent of the underlying transport, network, data link and physical layer. This part of ISO 27145 does not specify any require
43、ments for the in-vehicle network architecture.This part of ISO 27145 is compatible with ISO 14229-1 and includes provisions to support the data set of SAE J1979-DA and SAE J2012-DA WWH-OBD.This part of ISO 27145 is intended for use with ISO 27145-4, which is the entry point for the protocol initiali
44、zation and is based on two different data links: Diagnostic communication over Controller Area Network (DoCAN), ISO 15765-1, ISO 15765-2, ISO 15765-4; Diagnostic communication over Internet Protocol (DoIP), ISO 13400 (all parts).Due to the usage of standard network layer protocols, future extensions
45、 to optional physical layers (e.g. wireless) are possible.Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicles emissions-related system, i.e. legislated OBD: ISO 15031 (all parts); legislated WWH-OBD:
46、ISO 27145 (all parts).This part of ISO 27145 includes capabilities required to satisfy OBD regulations for multiple regions, vehicle types, model years, and engine types. Those regulations are not yet final for some regions and are expected to change in the future. This part of ISO 27145 does not at
47、tempt to interpret the regulations and does not include applicability of the included diagnostic services and data parameters for various vehicle applications. It is intended that users of this part of ISO 27145 verify the applicability of each of its clauses for a specific vehicle, engine, model ye
