We respect your privacy and are
committed to protecting it. The
information contained in this publication
was correct at the time of going to print,
but as technology rapidly changes, we
recommend that you visit the regional Ford
website for the latest information.
Your vehicle has electronic control units
that have data recording functionality and
the ability to permanently or temporarily
store data. This data could include
information on the condition and status of
your vehicle, vehicle maintenance
requirements, events and malfunctions.
The types of data that can be recorded are
described in this section. Some of the data
recorded is stored in event logs or error
logs.
Note:
Error logs are reset following a service
or repair.
Note: We may provide information in
response to requests from law enforcement,
other government authorities and third
parties acting with lawful authority or
through a legal process. Such information
could be used by them in legal proceedings.
Data recorded includes, for example:
• Operating states of system
components, for example, fuel level,
tire pressure and battery charge level.
• Vehicle and component status, for
example, wheel speed, deceleration,
lateral acceleration and seatbelt
status.
• Events or errors in essential systems,
for example, headlamps and brakes.
• System responses to driving situations,
for example, airbag deployment and
stability control.
• Environmental conditions, for example,
temperature. Some of this data, when used in
combination with other information, for
example, an accident report, damage to a
vehicle or eyewitness statements, could
be associated with a specific person.
Service Data
Service data recorders in your vehicle are
capable of collecting and storing
diagnostic information about your vehicle.
This potentially includes information about
the performance or status of various
systems and modules in the vehicle, such
as engine, throttle, steering or brake
systems. In order to properly diagnose and
service your vehicle, Ford Motor Company
(Ford of Canada in Canada), and service
and repair facilities may access or share
among them vehicle diagnostic
information received through a direct
connection to your vehicle when
diagnosing or servicing your vehicle.
Additionally, Ford Motor Company (Ford
of Canada, in Canada) may, where
permitted by law, use vehicle diagnostic
information for vehicle improvement or
with other information we may have about
you, for example, your contact information,
to offer you products or services that may
interest you. Data may be provided to our
service providers such as part suppliers
that may help diagnose malfunctions, and
who are similarly obligated to protect data.
We retain this data only as long as
necessary to perform these functions or to
comply with law. We may provide
information where required in response to
official requests to law enforcement or
other government authorities or third
parties acting with lawful authority or court
order, and such information may be used
in legal proceedings. For U.S. only (if
equipped), if you choose to use connected
apps and services, you consent that certain
diagnostic information may also be
accessed electronically by Ford Motor
Company and Ford authorized service
