Vehicle Data Collection and Event
Data Recorders
Your vehicle, like other modern motor vehicles,
has a number of sophisticated computer systems
that monitor and control several aspects of the
vehicle’s performance. Your vehicle uses on-board
vehicle computers to monitor emission control
components to optimize fuel economy, to monitor
conditions for airbag deployment and, if so
equipped, to provide anti-lock braking and to help
the driver control the vehicle in difficult driving
situations. Some information may be stored during
regular operations to facilitate repair of detected
malfunctions; other information is stored only in a
crash event by computer systems, such as those
commonly called Event Data Recorders (EDR).
In a crash event, computer systems, such as the
airbag Sensing and Diagnostic Module (SDM)
in your vehicle may record information about the
condition of the vehicle and how it was operated,
such as data related to engine speed, brake
application, throttle position, vehicle speed, safety
belt usage, airbag readiness, airbag performance,and the severity of a collision. If your vehicle is
equipped with StabiliTrak
®, steering performance,
including yaw rate, steering wheel angle, and
lateral acceleration, is also recorded. This
information has been used to improve vehicle
crash performance and may be used to improve
crash performance of future vehicles and
driving safety. Unlike the data recorders on many
airplanes, these on-board systems do not
record sounds, such as conversation of vehicle
occupants.
To read this information, special equipment is
needed and access to the vehicle or the device
that stores the data is required. GM will not access
information about a crash event or share it with
others other than:
with the consent of the vehicle owner or, if the
vehicle is leased, with the consent of the
lessee,
in response to an official request of police or
similar government office,
as part of GM’s defense of litigation through
the discovery process, or
as required by law.
