7 Foreword 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 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures 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 rules of the ISO/IEC Directives, Part 2 (see 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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement. For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISO s adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information The committee responsible for this document is ISO/TC 22, Road vehicles, Subcommittee SC 31, Data communication. This third edition cancels and replaces the second edition (ISO :2011), which has been technically revised. It also incorporates the Amendment ISO :2011/Amd 1:2013.

8 Introduction This part of ISO has been established in order to define common requirements for vehicle diagnostic systems implemented on a Controller Area Network (CAN) communication link, as specified in ISO Although primarily intended for diagnostic systems, it also meets requirements from other CAN based systems needing a network layer protocol. To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model, in accordance with ISO/IEC and ISO/IEC 10731, which structures communication systems into seven layers as shown in Table 1. Table 1 Enhanced and legislated OBD diagnostic specifications applicable to the OSI layers OSI 7 layers a Application (layer 7) Presentation (layer 6) Vehiclemanufacturerenhanced diagnostics ISO , ISO Vehicle manufacturer specific Legislated OBD (on-board diagnostics) Legislated WWH-OBD (on-board diagnostics) ISO ISO , ISO ISO , ISO , ISO , SAE J1930 DA, SAE J1979 DA, SAE J2012 DA Session (layer 5) ISO Transport protocol (layer 4) ISO ISO Network (layer 3) Data link (layer 2) ISO ISO Physical (layer 1) ISO , ISO , ISO , or vehicle manufacturer specific ISO , ISO a 7 layers according to ISO/IEC and ISO/IEC ISO ISO , SAE 1930-DA, SAE J1979 DA, SAE J2012 DA, SAE J1939-DA (SPNs), SAE J Appendix A (FMIs) ISO , ISO ISO , ISO ISO , ISO ISO The application layer services covered by ISO have been defined in compliance with diagnostic services established in ISO and ISO , but are not limited to use only with them. The transport protocol and network layer services covered by this part of ISO have been defined to be independent of the physical layer implemented, and a physical layer is only specified for legislated on-board diagnostics (OBD). For other application areas, ISO can be used with any CAN physical layer. vi

9 Road vehicles Diagnostic communication over Controller Area Network (DoCAN) Part 4: Requirements for emissions-related systems 1 Scope This part of ISO specifies requirements for Controller Area Networks (CAN) where one or more controllers comply with on-board diagnostics (OBD) or world-wide harmonized on-board diagnostics (WWH OBD) regulations. The network presumes the use of an external test equipment for inspection and repair diagnostics, as defined by the regulations. The CAN network requirements for the vehicle and the external test equipment are based on the specifications of ISO , ISO and ISO This part of ISO places restrictions on those International Standards for the fulfilment of the regulations. It does not specify in-vehicle CAN bus architecture, but seeks to ensure that the vehicle s regulated CAN communications comply with external test equipment requirements. This part of ISO defines the requirements to successfully establish, maintain and terminate communication with a vehicle that implements the requirements of the OBD/WWH-OBD regulations. Plug and-play communication capabilities among vehicles and test equipment are defined to assure the interoperation of external test equipment and vehicles. This part of ISO details all of the OSI layer requirements to achieve this goal. This part of ISO is the entry point for DoCAN (Diagnostic communication over Controller Area Network). Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicle s emissions-related system: legislated OBD: ISO (all parts); legislated WWH-OBD: ISO (all parts). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
