13、 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 interested in a subject for which a technical committee has been established has the
14、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.The procedu
15、res used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial
16、rules of the ISO/IEC Directives, Part 2. www.iso.org/directivesAttention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

21、ogether, provide a coherent self-consistent set of specifications to facilitate emissions-related diagnostics. ISO 15031-1 provides an introduction to the series of International Standards. ISO 15031-2 to ISO 15031-7 are based on Society of Automative Engineers (SAE) recommended practices. This part
22、 of ISO 15031 is based on SAE J1978.This International Standard includes the communication between the vehicles On-Board Diagnostics (OBD) systems and test equipment implemented across vehicles within the scope of the legislated emissions-related OBD.To achieve this, it is based on the Open Systems
23、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 services specified by this International Standard are broken into the following: Diagnostic services (layer 7), sp

It references SAE J1930-DA which co
32、ntains all standardized naming objects, terms, and abbreviations. SAE J1979: 15031-5 is concerned with the definition of emissions-related diagnostic services (diagnostic test modes). It references SAE J1979-DA which contains all standardized data items like PIDs, TIDs, OBDMIDs, and ITIDs. SAE J2012
33、: 15031-6 is concerned with the procedure for defining emissions-related diagnostic trouble codes. It references SAE J2012-DA which contains all standardized data items like DTCs and FTBs.vi ISO 2014 All rights reservedBS ISO 15031-4:2014ISO 15031-4:2014(E)ISO 15031-4Emissions OBDExternal test equip

43、BD services). This part of ISO 15031 specifies a complementary set of facilities, to be provided by external test equipment, which will include scan tool facilities. These facilities provide complete, efficient, and safe access to all of the public OBD (on-board diagnosis) services on any vehicle, w
44、hich is compliant with this part of ISO 15031.This part of ISO 15031 specifies a means of establishing communications between an OBD-equipped vehicle and external test equipment, and a set of diagnostic services to be provided by the external test equipment in order to exercise the services defined
45、in ISO 15031-5.This part of ISO 15031 does not preclude the inclusion of additional capabilities or functions in external test equipment. However, it is the responsibility of the external test equipment designer to ensure that no such capability or function can adversely affect either an OBD-equippe
