Export data related to motor vehicle pre-defined events in usage history is collected, recorded, stored, and exported by motor vehicle event data recorders (MVEDRs). A protocol for MVEDR output data compatibility and export protocols of MVEDR data elements is defined by this standard. A motor vehicle event data recorder connector lockout apparatus (MVEDRCLA) and a near field communication (NFC) protocol is defined for safeguarding access to a vehicle’s event data recorder (EDR) data by securing the vehicle output diagnostic link connector (DLC) and establishing a chain of custody link. This standard is without prejudice to requirements of national or regiona...

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 w...

Many light-duty motor vehicles, and increasing numbers of heavy commercial vehicles, are equipped with some form of MVEDR. These systems, which are designed and produced by individual motor vehicle manufacturers and component suppliers, are diverse in function, and proprietary in nature, however, the SAE J1962 [B118]2 (ISO 15031-3:2004 [B55]) vehicle DLC has a common design and pinout, and is thus universally used to access event data recorder information. Data access via the DLC can be accomplished by using scan tools or microcomputers and network interfaces. This same DLC and network interface is also used for re-calibrating electronic control units on a v...
