Vehicle Data Collection and Event
Data Records
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 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 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 engine speed, brake applications, throttle position,
vehicle speed, seat belt usage, airbag readiness, airbag
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,
