Data stored in the vehicle
A wide range of electronic components in
your vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about:
R
the vehicle's operating state
R
events
R
faults
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example:
R
operating conditions of system compo-
nents, e.g. fluid levels
R
the vehicle's status messages and those of
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
R
malfunctions and defects in important sys-
tem components, e.g. lights, brakes
R
vehicle reactions and operating conditions
in special driving situations, e.g. airbag
deployment, intervention of stability con-
trol systems
R
ambient conditions, e.g. outside tempera-
ture
This data is of an exclusively technical nature
and can be used to:
R
assist in recognising and rectifying faults
and defects
R
analyse vehicle functions, e.g. after an acci-
dent
R
optimise vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data mem-
ory and fault data memory.
Services include, for example:
R
repair services
R
service processes
R
warranties
R
quality assurance
It is read by employees of the service network
(including manufacturers) using special diag-
nostic testers. More detailed information is
obtained from it, if required.
After a fault has been rectified, the informa-
tion is deleted from the fault memory or is
continually overwritten.
When operating the vehicle, situations are
conceivable in which this technical data, in
connection with other information (if neces-
sary, under consultation with an authorised
expert), could be traced to a person.
Examples include:
R
accident reports
R
damage to the vehicle
R
witness statements
Further additional functions that have been
contractually agreed upon with the customer
allow certain vehicle data to be conveyed by
the vehicle as well. The additional functions
include, for example, vehicle location in case
of an emergency.
