The use of electronic data in conjunction with traditional methods of crash reconstruction is becoming more common and more complex. While the “Big 3” domestic automobile manufacturers (GM, Ford and Chrysler) have all previously provided access to this electronic data, the foreign manufacturers are now also beginning to provide access to their electronic data as the deadline for Part 563 of the Federal Regulation which mandates the eventual uniformity of collection and reporting looms closer. In 2011 Toyota (the second largest vehicle manufacturer in the United States) began to provide access to their electronic data and other foreign manufacturers are expected to follow in their footsteps.
Electronic data recorded during the onset of an event may be stored in a variety of components which compose the vehicles electronic control systems such as; the airbag control module (ACM), powertrain control module (PCM) or the rollover sensor (ROS). These electronic modules independently or communally contain event data recorders (EDR’s) which store the systems status and/or severity of the crash pulse. While the training and experience necessary to recover these modules, or simply image a copy of the data they contain, has remained relatively consistent the training to analyze the data and what it means is constantly evolving.
Similarly, the acceptance and admissibility of this electronic data is constantly being reviewed and refined by the court systems both locally and on a state-by-state basis. Introtech personnel routinely assist local law-enforcement agencies and prosecutors with the execution of search warrants to secure the electronic data for the use in criminal prosecutions.
