Crash Data Retrieval

The Bosch Crash Data Retrieval System is a litigation proven tool that allows the Professional Analysis and Consulting accident reconstruction experts investigating vehicle crashes the opportunity to image crucial crash data parameters leading up to and during a Accident Site Documentationcrash. This crash data, which is stored in the vehicle’s Airbag Control Module (ACM), may be used to make informed decisions about the accident based on the crash data “imaged” from the vehicle in question. The system currently supports most vehicles on the road today.

The ACM’s potential capability to save data after a crash has caused some to mistakenly refer to it as an “Event Data Recorder” or EDR, sometimes referred to as the “Black Box”. In reality, the ACM’s primary job is to detect sudden changes in direction and/or rotation and, when appropriate, deploy restraint devices like airbags. The ACM uses certain bits of information including that from crash sensing systems, seat belt related sensors and occupant detection systems, to decide whether or not and when to deploy airbags and other restraint system devices. When certain conditions are met, the ACM may record data associated with these sudden changes in direction and/or rotation (i.e. a crash) which can later be “imaged” by the CDR tool.
