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 air bag 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 or near crash
event by computer systems commonly called event data
recorders (EDR).
In a crash or near crash event, computer systems, such
as the Air Bag Sensing and Diagnostic Module (SDM) in
your vehicle may record information about the condition
of the vehicle and how it was operated, such as engine
speed, brake applications, throttle position, vehicle
speed, safety belt usage, air bag readiness, air bag
performance data, and the severity of a collision. 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 SDM 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.
In addition, once GM collects or receives data, GM may
•
use the data for GM research needs,
•
make it available for research where appropriate
confidentiality is to be maintained and need is
shown, or
•
share summary data which is not tied to a specific
vehicle with non-GM organizations for research
purposes.
Others, such as law enforcement, may have access to
the special equipment that can read the information
if they have access to the vehicle or SDM.
If your vehicle is equipped with OnStar
®
, please check
the OnStar
®
subscription service agreement or manual
for information on its operations and data collection.
