13、bodies). 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

14、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 Directive

15、s, 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 c

16、asting 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 27145-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee

17、 SC 3, Electrical and electronic equipment. This first edition of ISO 27145-2 cancels and replaces ISO/PAS 27145-2:2006, which has been technically revised.

20、lations (WWH-OBD GTR). It has been established in order to apply the unified diagnostic services (specified in ISO 14229-1) to WWH-OBD systems. The ISO 27145 series includes the communication between the vehicles WWH-OBD systems and external (off-board) “generic“ test equipment within the scope of t

21、he country-specific regulatory requirements. To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. Where mapped on this model, the services specified by ISO 27145 are

22、 divided into diagnostic services (layer 7), specified in ISO 27145-3 with reference to ISO 14229-1, presentation layer (layer 6), specified in this part of ISO 27145 with reference to SAE J1930-DA, SAE J1939 Companion Spreadsheet (SPNs), SAE J1939-73:2010, Appendix A (FMIs), SAE J1979-DA and SAE J2

29、1939-73: SAE J1939 Companion Spreadsheet indexes names for suspect parameter numbers (SPNs), which provide an alternative presentation format for SAE J2012-DA DTCs. SPNs are combined with failure mode indicators (FMIs) to form the full alternative presentation. FMIs are described in SAE J1939-73:201

42、ory data elements of the ISO 27145 series. The data elements are used to provide the external test equipment with the diagnostic status of the vehicle on-board diagnostics (VOBD) system in the vehicle. All data elements are communicated with the unified diagnostic services as defined in ISO 27145-3.

43、 The data elements are diagnostic trouble codes (DTCs), data identifiers (DIDs) and routine identifiers (RIDs). The mapping from parameter identifiers (PIDs), monitor identifiers (MIDs) and info type identifiers (ITIDs) is described in this part of ISO 27145. If new legislated WWH-OBD GTR modules ar

44、e established, it is intended that ISO 27145 be applicable with possible extensions, which can be included in this part of ISO 27145, can be specified as enhancements of the SAE Digital Annexes or can even be part of other referenced documents which are intended to include the applicable data defini

45、tions. ISO 27145 is intended to become the single communication standard for access to OBD-related information (VOBD). To allow for a smooth migration from the existing communication standards to this future world-wide communication standard, the communication concept as specified in ISO 27145-4 is

46、based on two different data links: ISO 15765-4 and ISO 13400 (all parts). In view of the usage of standard network layer protocols, future extensions to optional physical layers (e.g. wireless) are possible. NOTE It is expected to extend ISO 27145-4 as necessary upon introduction of additional commu

47、nication media. ISO 27145-4 is the entry point to establish communication with the vehicle. 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

48、 series, and legislated WWH-OBD: ISO 27145. Vehicles according to ISO 27145 provide VOBD system support as envisioned for WWH-OBD by Global Technical Regulation (GTR) No. 5.
