标准范围
This part of ISO 22901 is intended to ensure that diagnostic data stream information is available to diagnostictool application manufacturers to simplify the support of the aftermarket automotive service industry. The ODXmodelled diagnostic data are compatible with the software requirements of the Modular VehicleCommunication Interface (MVCI) (ISO 22900-2 and ISO 22900-3). The ODX modelled diagnostic data canenable an MVCI device to communicate with the vehicle [ECU(s)] and interpret the diagnostic data containedin the messages exchanged between the external test equipment and the ECU(s). For ODX-compliantexternal test equipment, no software programming is necessary to convert diagnostic data into technicianreadableinformation for display by the external test equipment.This part of ISO 22901 contains emissions-related OBD data examples described in ODX. The data examplesderive 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 specification from diagnostic communication of emissions-related ECUs;—the communication parameters for the emissions-related OBD protocols and data link layers and foremissions-related ECU software;—the related vehicle interface description (connectors and pin-out);—the functional description of diagnostic capabilities of a network of ECUs.This part of ISO 22901 is based on emissions-related diagnostic data derived and formatted according to theISO 15765-4 DoCAN protocol. The definitions and XML representation is exemplary for all other protocols thatare referenced in ISO 15031-5.
