Airbag SDM ' Black Box ' Crash Data Retrieval Information for GM
Cars
The benefit of retrieving data from flight data recorder using
the Black Box was only available to airlines for many years.
This invaluable instrument, which helps determine what happened
in the critical time before a crash, is now available as Airbag
SDM crash data retrieval system on GM cars.
In response to the call of the National Transport and Safety
Board (NTSB) in 1997 that vehicle manufacturers and the National
Highway Traffic Safety Administration team up to gather
information on vehicle crashes using on board collision sensing
and recording devices, General Motors expanded the data
downloaded to permanent memory in the air bag sensing and
diagnostic module at deployment or in a near deployment
collision.
The capability to record pre-crash data has since expanded with
time and technological advancement. General Motor's Vetronix
crash data retrieval tool (CDR) collects vehicle crash data via
the air bag system SDM.
General motors together with Vetronix Corporation developed the
Vetronix CDR System, which downloads the data stored in
recordable airbag modules.
Software, hardware and interface cables allow recorded data such
as Delta V, driver seat belt usage and pre-impact data to be
downloaded to commonly used computers in easy to read format.
Interface cables that connect directly to the airbag module are
available for vehicles that cannot be powered up after a crash.
This new technology then also makes it easy for investigators to
input other vital information, like weather conditions, and send
the data to a remote database. The final 5 seconds leading up to
an accident event is very vital information that can be stored
at the airbag SDM module recorder. This process can only be done
using the Vetronix CDR equipment and a PC.
Includes most 1994 and newer Chevrolet, GMC, Buick, Oldsmobile,
Pontiac, Cadillac, GM trucks, Saturn, and Hummer vehicles have
GM airbag SDM recorded data coverage. Parts Train is where you
