tenance requirements, events or errors can be
stored temporarily or permanently.
ted data can be processed within the vehicle, for
example to play the user's favourite music.
This information generally documents the condi‐
tion of a component, a module, a system or the
vehicle surroundings, including:
Depending on the vehicle equipment, this data
includes:
▷ Multimedia data such as music, films or pho‐
tos for playback in an integrated multimedia
system.
▷ Operating states of system components,
for example fill levels, tyre inflation pressure,
battery status.
▷ Address book data for use in conjunction with
an integrated hands-free system or an
integrated navigation system.
▷ Malfunctions and faults of important system
components, for example lights and brakes.
▷ Responses of the vehicle to particular driving
situations, for example triggering of an airbag,
activation of the drive stability control sys‐
tems.
▷ Destinations: depending on the equipment,
route guidance can be started automatically
with the aid of destinations which have been
taught in by the navigation system.
▷ Information on vehicle-damaging events.
▷ Data on usage of Internet services.
The data is required so that the control units can
perform their functions. It is also used for detect‐
ing and rectifying malfunctions, as well as to opti‐
mise vehicle functions.
This data may be saved locally in the vehicle or
stored on a device that has been connected to
the vehicle, for example a smartphone, USB stick
or MP3 player.
Most of this data is transient and is only pro‐
cessed within the vehicle itself. Only a small pro‐
portion of the data is stored in event or error
memories in response to specific circumstances.
Service data
General
When service work is required, for example re‐
pairs, service operations, warranty work and qual‐
ity assurance measures, this technical informa‐
tion can be read out from the vehicle together
with the vehicle identification number.
Personal settings
Convenience functions, such as seat, climate or
light settings, make every journey even more
pleasant. The personal settings for these func‐
tions can be saved in a profile within the vehicle
and retrieved on request, for example if the set‐
tings have been changed by another driver. De‐
pending on the equipment, these profiles can be
saved in the vehicle manufacturer's secure data
systems. When the driver changes vehicle, these
saved profiles can simply be applied to a differ‐
ent vehicle.
Stored data
Electronic vehicle components may contain data
storage media which store technical information
relating to the vehicle condition, events and er‐
rors. The data required for service measures is
processed locally and is deleted automatically
once the work is complete. A Service Partner of
the manufacturer or another qualified Service
Partner or a specialist workshop can read out the
information. As part of service and repair orders,
data is read out via the OBD diagnostic socket
using special diagnosis systems and transferred
to the vehicle manufacturer. The customer is en‐
titled to object to the data being read out and for‐
warded.
The vehicle settings saved in the vehicle profile
can be changed or deleted at any time.
Multimedia and navigation
Data can also be imported into the vehicle enter‐
tainment and communication system, for exam‐
ple via a smartphone or MP3 player. The impor‐
