The data memory temporarily or permanently
stores technical information about:
the vehicle's operating state
R
events
R
faults
R
The technical information generally docu-
ments the condition of a component, module,
system or the environment.
These include, for example:
The operating status of system components,
R
e.g. fluid levels
Status messages concerning the vehicle and
R
its individual components, e.g. number of
wheel revolutions/speed, deceleration in
movement, lateral acceleration, accelera-
tor pedal position
Malfunctions and defects in key system
R
components, including, for instance,
lights, brakes.
Vehicle reactions and operating condi-
R
tions in special driving situations,
including, for instance, deployment of an
airbag, use of stability control systems.
Environmental conditions, including, for
R
instance, the outside temperature.
This data is of an exclusively technical
nature and can be used to:
assist in the detection and elimination of
R
faults and defects
analyse vehicle functions, e.g. after an
R
accident
optimise vehicle functions
R
The data cannot be used to trace the vehicle's
movements.
If you have the vehicle serviced, this tech-
nical information can be read out from the
event and fault data memory.
Services include, for example, information
on:
repair work
R
service work
R
warranty claims
R
quality assurance
R
The readout is handled by service network
staff (including the manufacturer) with the
help of special diagnostic testers. You can
obtain more detailed information, if
required.
After the fault has been rectified, the infor-
mation is cleared in the fault memory or is
sequentially overwritten.
During vehicle operation, certain situations
may arise in which this technical data - in
conjunction with other information and, if
applicable, after consultation with an
approved assessor - may be linked to an indi-
vidual person.
Examples of this include:
accident reports
R
vehicle damage
R
evidence
