<P> Downloading an airbag module in most vehicles is best accomplished by connecting the appropriate scanning tool to the Diagnostic Link Connector (DLC) usually found under the vehicle's dashboard near the driver's knees . Alternately, some modules can be downloaded "on the bench" after removal from the vehicle . </P> <P> Over 88% of model year 2016 and newer vehicles are supported by the Bosch CDR tool, enabling the retrieval of Event Data Recorder (EDR) data from a vehicle that has been involved in a crash . This tool is made up of hardware and software which provides the ability to "image", "download", or "retrieve" EDR data that may be stored in the control modules of passenger cars, light trucks and SUVs . The software component is a single, standalone program designed to run in a Windows environment . The hardware part of the Tool is a collection of components including cables and adapters which, with proper training and minimal difficulty, are used to "retrieve" data from supported vehicles . </P> <P> Another 11% of model year 2016 and newer vehicles are supported by other EDR tools . The limited need to cover less commonly supported vehicles may make the initial investment in software and equipment unnecessary for many in the accident reconstruction or related industries . </P> <P> From 1998 to 2001, the National Highway Traffic Safety Administration (NHTSA) sponsored a working group specifically tasked with the study of EDRs . After years of evaluation, NHTSA released a formal Notice of Proposed Rulemaking in 2004 . This notice declared NHTSA's intent to standardize EDRs . It was not until August 2006 that NHTSA released its final ruling (49 CFR Part 563). The ruling was lengthy (207 pages), consisting of not only definitions and mandatory EDR standards, but also acted as a formal reply to the dozens of petitions received by NHTSA after the 2004 notice . </P>
