Crash Data Retrieval System (CDR)

The Crash Data Retrieval system is designed to retrieve pre and post-crash data from the vehicle’s airbag module or event data recorder. This data is a valuable tool in the reconstruction process of a collision and can give insight into the driver’s pre-crash perception and driving tactics. It is physical evidence and for years has been laying dormant and neglected. The CDR system allows the data to be harvested and used in a reconstruction process.

Neese & Associates uses the latest software version and technology and trained to download and analyze the event data recorder data. Currently, the Bosch Crash Data Retrieval Software and Hardware is the only public means to downloading the data recorders.

The National Highway Transportation Safety Administration’s mission is to save lives, prevent injuries, and reduce health care and other economic costs associates with motor vehicle crashes. NHTSA recognized there was valuable crash data in the crashed vehicles stored throughout the country that they could use in their efforts if they could retrieve that data. That data was being stored in the vehicles’ airbag control modules with the development of the “smarter” airbags since 1996.

The Crash Data Retrieval is the result of that endeavor. As a result NHTSA has developed a uniform, national requirement for vehicles with event data recorders concerning the collection, storage and retrievability of onboard motor vehicle crash event data. All vehicles manufactured on or after September 1, 2012, if equipped with an event data recorder, must meet these requirements (Part 563). Prior to this date some of the automobile manufacturers voluntarily made their vehicle event data recorders available for retrieval.
