ECU CHEVROLET IMPALA 2009 9.G Workshop Manual

To read data recorded by an EDR, special equipment
is required, and access to the vehicle or the EDR
is needed. In addition to the vehicle manufacturer,
other parties, such as law enforcement, that have
the special equipment, can read the information if
they have access to the vehicle or the EDR.
GM will not access this data or share it with others
except: 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.
Data that GM collects or receives may also be used for
GM research needs or may be made available to others
for research purposes, where a need is shown and the
data is not tied to a specic vehicle or vehicle owner.
OnStar®
If your vehicle has OnStar and you subscribe to the
OnStar services, please refer to the OnStar Terms
and Conditions for information on data collection and
use. See alsoOnStar
®System on page 2-33in
this manual for more information.
Navigation System
If your vehicle has a navigation system, use of the
system may result in the storage of destinations,
addresses, telephone numbers, and other trip
information. Refer to the navigation system operating
manual for information on stored data and for deletion
instructions.
Radio Frequency
Identication (RFID)
RFID technology is used in some vehicles for functions
such as tire pressure monitoring and ignition system
security, as well as in connection with conveniences
such as key fobs for remote door locking/unlocking and
starting, and in-vehicle transmitters for garage door
openers. RFID technology in GM vehicles does not
use or record personal information or link with any
other GM system containing personal information.
