11、72 BS ISO 22901-2:2011ISO 22901-2:2011(E) iv ISO 2011 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 through ISO tec
12、hnical 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 closel
13、y 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 Standards. Draft
14、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 this documen
15、t may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 22901-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 22901 consists of the following parts, under t

The automotive industry mostly utilizes an informal
23、 description to document diagnostic data stream information of vehicle ECUs. Each user, who desires to use the ECU diagnostic data stream documentation to setup development tools or service diagnostic test equipment, has a requirement for a manual transformation of this documentation into a format r
24、eadable by these tools. This effort will no longer be required if the diagnostic data stream information is provided in ODX format and if those tools support the ODX format.

25、pen diagnostic data exchange (ODX) Part 2: Emissions-related diagnostic data 1 Scope This part of ISO 22901 is intended to ensure that diagnostic data stream information is available to diagnostic tool application manufacturers to simplify the support of the aftermarket automotive service industry.
26、The ODX modelled diagnostic data are compatible with the software requirements of the Modular Vehicle Communication Interface (MVCI) (ISO 22900-2 and ISO 22900-3). The ODX modelled diagnostic data can enable an MVCI device to communicate with the vehicle ECU(s) and interpret the diagnostic data cont
27、ained in the messages exchanged between the external test equipment and the ECU(s). For ODX-compliant external test equipment, no software programming is necessary to convert diagnostic data into technician-readable information for display by the external test equipment. This part of ISO 22901 conta
28、ins emissions-related OBD data examples described in ODX. The data examples derive from ISO 15031 (all parts). EXAMPLES Diagnostic trouble codes, data parameters, identification data and communication parameters. The emissions-related OBD ODX modelled diagnostic data describe the protocol specificat
29、ion from diagnostic communication of emissions-related ECUs; the communication parameters for the emissions-related OBD protocols and data link layers and for emissions-related ECU software; the related vehicle interface description (connectors and pin-out); the functional description of diagnostic
30、capabilities of a network of ECUs. This part of ISO 22901 is based on emissions-related diagnostic data derived and formatted according to the ISO 15765-4 DoCAN protocol. The definitions and XML representation is exemplary for all other protocols that are referenced in ISO 15031-5. 2 Normative refer

35、ECU life cycle. Engineering, manufacturing, and service specify that communication protocol and data should be implemented in the ECU. This information is documented in a structured format utilizing the XML standard and by an appropriate ODX authoring tool. There is potential to generate ECU softwar
36、e from the ODX file. Furthermore, the same ODX file is used to set up the diagnostic engineering tools to verify proper communication with the ECU and to perform functional verification and compliance testing. Once all quality goals are met, the ODX file may be released to a diagnostic database. Dia
37、gnostic information is now available to manufacturing, service, OEM franchised dealers and aftermarket service outlets via Intranet and Internet. Figure 1 Usage of ODX data in the ECU life cycle BS ISO 22901-2:2011ISO 22901-2:2011(E) ISO 2011 All rights reserved 3The objective of this specification
38、is to ensure that diagnostic data from any vehicle manufacturer is independent of the testing hardware and protocol software supplied by any test equipment manufacturer. 6 Emissions-related OBD ODX use cases 6.1 Use case 1 OBD Scan Tool based on a Modular VCI architecture and ODX This use case descr
39、ibes the usage of an OBD scan tool in accordance with ISO 15031-4 / SAE J1978 and implemented according to the Modular VCI specification (see ISO 22900, parts 1, 2 and 3) and ODX (see ISO 22901-1). The benefits of an emissions-related OBD scan tool that is based on the Modular VCI and ODX standard a
40、re the following: no software programming to support the implementation of new diagnostic trouble codes (see ISO 15031-6 / SAE J2012-DA), new PIDs, Test IDs, Monitor IDs, Info Type IDs, and Scaling IDs (see ISO 15031-5 / SAE J1979-DA); OBD scan tool applications in accordance with ISO 15031-4 are de
41、veloped only once and are not impacted by modifications / changes in the definition of emissions-related OBD data and formats; separation of application, communication logic and data items. NOTE The Modular VCI software architecture supports the emissions-related OBD scan tool requirements as well a
42、s enhanced diagnostic protocols, data streams and applications. Figure 2 illustrates external test equipment connected to the vehicles diagnostic connector. The OBD scan tools software architecture is compliant to the Modular VCI specifications. The diagnostic kernel is the key software component of
43、 the Modular VCI system. It implements the D-PDU API (see ISO 22900-2), the D-Server API (see ISO 22900-3) and the interface to the ODX derived runtime data. The OBD scan tool application depends on standardized names or naming conventions as defined by this part of ISO 22901. These names are define
44、d in the emissions-related ODX data and utilized by the OBD scan tool application to address logical links, services, and emission-related data. Using the standardized names and structures from this part of ISO 22901, the interface to implement the scan tool application against is clearly defined. T
45、his is indicated by the dashed line in Figure 2. The D-PDU API is a software component of the tool suppliers Modular VCI protocol module. It connects the diagnostic kernel with any Modular VCI compatible vehicle communication interface. The D-Server API of the diagnostic kernel provides a standardiz
46、ed interface to the OBD scan tool applications. These applications shall be in accordance with ISO 15031-4, which implements the standardized data and messages of ISO 15031-5 and ISO 15031-6. The emissions-related ODX runtime data format is tool supplier specific. The runtime format is not contained
47、 in the ODX standard (see ISO 22901-1). Based on the use cases supported by the diagnostic tool, the content and structure of the ODX runtime data format and content may differ. However, for emissions-related OBD the OBD scan tool applications and ODX runtime data shall support the full scope of ISO
48、 15031 (all parts) and the respective SAE J documents. All emissions-related OBD data as specified in ISO 15031-5 and SAE J1979-DA, ISO 15031-6 and SAE J2012-DA shall be authored according to the requirements established in this part of ISO 22901. This use case requires the unique and complete defin
49、ition of all elements necessary for any OBD scan tool application compliant to ISO 22900.
