IEEE 1616-2021

Motor vehicle event data recorders (MVEDRs) collect, record, store, and export data related to motor vehicle pre-defined events in usage history. This standard defines a protocol for MVEDR output data compatibility and export protocols of MVEDR data elements. This standard does not prescribe which specific data elements shall be recorded, but instead provides a data dictionary of data attributes. This standard also defines a means of maintaining data security on the vehicle via a motor vehicle diagnostic link connector lockout apparatus (MVEDRCLA) by securing the vehicle output diagnostic link connector (DLC). This standard does not prescribe data security within the vehicle electronic control units (ECUs) or within the intra-vehicle communication and/or diagnostic networks; it instead defines ways and means to permit uniform but controlled access of electronic scan tools to the DLC for legitimate vehicle emissions status, maintenance, and/or repair. This standard also defines a motor vehicle event data recorder connector lockout apparatus (MVEDRCLA) and a near field communication (NFC) protocol of safeguarding access to a vehiclea??s event data recorder (EDR) data by securing the vehicle output diagnostic link connector (DLC). This standard is without prejudice to requirements of national or regional laws related to privacy, data protection, and personal data processing. This standard does not directly address related issues with regard to human health or human safety. It is applicable to vehicles and their respective event data recorders for all types of motor vehicles licensed to operate on public roadways, whether offered as original or aftermarket equipment, whether stand-alone or integrated within the vehicle.
