  Crash Data Retrieval (CDR)* Technician 1 & 2 Certification (2 days)
  Crash Data Retrieval (CDR)* Data Analyst Certification (1 week)
Crash Data Retrieval (CDR) is the term for the retrieval of crash data, pre-crash data, and other recorded data from passenger cars, SUVs and light trucks using a specific software and hardware system designed for this purpose. This system was originally designed by Vetronix, and later acquired by Bosch. The system has been, and is, expanded regularly. The system was designed in conjunction with vehicle manufacturers, with involvement by the National Highway Traffic Safety Administration (NHSTA). This system accesses selected control modules in many vehicles for the crash and event related data. This data is recorded on the Event Data Recorders (EDR) associated with Airbag Control Modules (ACM), Powertrain Control Modules (PCM) or Roll-over Sensors (ROS) in these vehicles. This data is retrieved either directly from the modules or through the Diagnostic Link Connector (DLC), using equipment specifically designed for this purpose. The data available, and its source, varies by vehicle manufacturer, vehicle model, and model year. Data is not currently available from all covered vehicle classes. The specific components of vehicles associated with Crash Data Retrieval, and the names and acronyms assigned to these components, can vary by vehicle manufacturer.

Latest updates to the overall document and activity counts (reports, affidavits, cases, trials, and depositions), and counts of the number of individual specialty cases reported in this website were completed 7/15/2020. The updates of the overall document and activity counts and the counts of the number of individual specialty cases for the period between 12/2007 and 7/15/2020 were based only on the documents produced, and thus are under-counts (i.e. cases without a report or affidavit were not included in the counts).
