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 the vehicle

has the Anti-lock Brake System (ABS), 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. 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.
