Omfang: <p>This part of <std std-id="iso:std:iso:22901:en" type="undated"><std-ref>ISO 22901</std-ref></std> 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. The ODX modelled diagnostic data are compatible with the software requirements of the Modular Vehicle Communication Interface (MVCI) (<std std-id="iso:std:iso:22900:-2:en" type="undated"><std-ref>ISO 22900-2</std-ref></std> and <std std-id="iso:std:iso:22900:-3:en" type="undated"><std-ref>ISO 22900-3</std-ref></std>). The ODX modelled diagnostic data can enable an MVCI device to communicate with the vehicle [ECU(s)] and interpret the diagnostic data contained 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.</p><p>This part of <std std-id="iso:std:iso:22901:en" type="undated"><std-ref>ISO 22901</std-ref></std> contains emissions-related OBD data examples described in ODX.
