Event Data Recorder (Edr) - Jeep Grand Cherokee Owner's Manual

Event Data Recorder (EDR)

In the event of an accident, your vehicle is
designed to record up to five seconds of spe-
cific vehicle data parameters (see list below) in
an event data recorder prior to the moment of
airbag deployment, or near deployment (if ap-
plicable), and up to a quarter second of either
high-speed deceleration data or change in
velocity during and/or after airbag deployment
or near-deployment. EDR data is ONLY re-
corded if an airbag deploys, or nearly deploys,
and is otherwise unavailable.
NOTE:
1. A near-deployment event occurs when
the airbag sensor detects severe vehicle
deceleration usually indicative of a crash,
but not severe enough to warrant airbag
deployment.
2. Under certain circumstances, EDR data
may not be recorded (e.g., loss of battery
power).
In conjunction with other data gathered during
a complete accident investigation, the elec-
tronic data may be used by Chrysler Group
LLC and others to learn more about the pos-
34
sible causes of crashes and associated injuries
in order to assess and improve vehicle perfor-
mance. In addition to crash investigations initi-
ated by Chrysler Group LLC, such investiga-
tions may be requested by customers,
insurance carriers, government officials, and
professional crash researchers, such as those
associated with universities, and with hospital
and insurance organizations.
In the event that an investigation is undertaken
by Chrysler Group LLC (regardless of initia-
tive), the company or its designated represen-
tative will first obtain permission of the appro-
priate custodial entity for the vehicle (usually
the vehicle owner or lessee) before accessing
the electronic data stored, unless ordered to
download data by a court with legal jurisdiction
(i.e., pursuant to a warrant). A copy of the data
will be provided to the custodial entity upon
request. General data that does not identify
particular vehicles or crashes may be released
for incorporation in aggregate crash data-
bases, such as those maintained by the gov-
ernment officials and various states. Data of a
potentially sensitive nature, such as would
identify a particular driver, vehicle, or crash, will
be treated confidentially. Confidential data will
not be disclosed by Chrysler Group LLC to any
third party except when:
1. Used for research purposes, such as to
match data with a particular crash record in an
aggregate database, provided confidentiality
of personal data is thereafter preserved.
2. Used in defense of litigation involving a
Chrysler Group LLC product.
3. Requested by police under a legal warrant.
4. Otherwise required by law.
Data parameters that are recorded:
• Diagnostic trouble code(s) and warning light
status for electronically-controlled safety
systems, including the airbag system
• Vehicle speed
• Engine RPM
• Brake switch status
• Pedal position
• And other parameters depending on vehicle
configuration
