Most modern automobiles collect crash related data including Delta V's, seat belt use, passenger seat occupancy, pre-impact speed, throttle, brake on/off and steering, etc. There can be no question that such electronic evidence can be an important part of a situationally complete accident reconstruction and/or biomechanical evaluation.
The Bosch Crash Data Retrieval (CDR) Tool can be used to obtain a copy of the electronic evidence of a crash stored in approximately 90% of automobiles' airbag control modules (ACM's) of the vehicles on the road in the United States. Supported manufacturers include Toyota, Lexus, Chevrolet, Buick, GMC, Cadillac, Pontiac, Dodge, Jeep, Chrysler, Ram, Ford, Lincoln, Mercury, Honda, Acura, Nissan, Infiniti, Mitsubishi, Mazda, Subaru and others.
Manufacturer tools allow access to the available electronic evidence in the other approximate 10% of automobiles sold in the United States since 2013 consisting of Hyundai & Kia, Tesla, and Land Rover & Jaguar.
Only Ferrari and Porsche (except for the Taycan) do not have EDR capability in their automobiles.
Automobiles typically record crash related data for both non-deployment (not locked) and deployment events (locked). Most non-deployment events are stored until replaced by subsequent non-deployment events, and most vehicles are capable of storing multiple events. Only early GM vehicles (Chevrolet, GMC, Pontiac, Buick, Cadillac, Saturn, Hummer, etc.) erased non-deployment events after a number of key cycles if the vehicle was driven for some number of key on/off cycles post crash.
The Bosch CDR Tool being used to obtain a copy of events stored in the airbag control module (ACM).
