entertainment functions, which are also made
possible by electronic control units.
Electronic control units contain data memories
which can temporarily or permanently store
technical information about the vehicle's operat‐
ing state, component loads, maintenance
requirements and technical events or malfunc‐
tions.
In general, this information documents the state
of a component part, a module, a system or the
surroundings such as:
Operating status of system components (e.g.
R
fill levels, battery status, tire pressure)
Status messages concerning the vehicle or
R
its individual components (e.g. number of
wheel revolutions/speed, longitudinal accel‐
eration, lateral acceleration, display of fas‐
tened seat belts)
Malfunctions or faults in important system
R
components (e.g. lights, brakes)
Information on events leading to vehicle
R
damage
System reactions in special driving situations
R
(e.g. airbag deployment, intervention of sta‐
bility control systems)
Ambient conditions (e.g. temperature, rain
R
sensor)
In addition to providing the actual control unit
function, this data assists the manufacturer in
detecting and rectifying malfunctions and opti‐
mizing vehicle functions. The majority of this
data is temporary and is only processed in the
vehicle itself. Only a small portion of the data is
stored in the event or fault memory.
When your vehicle is serviced, technical data
from the vehicle can be read out by service net‐
work employees (e.g. workshops, manufactur‐
ers) or third parties (e.g. breakdown services).
Services include repair services, maintenance
processes, warranty claims and quality assur‐
ance measures, for example. The read out is per‐
formed via the legally prescribed port for the
diagnostics connection in the vehicle. The
respective service network locations or third
parties collect, process and use the data. They
document technical statuses of the vehicle,
General notes
assist in finding malfunctions and improving
quality and are transmitted to the manufacturer,
if necessary. Furthermore, the manufacturer is
subject to product liability. For this, the manu‐
facturer requires technical data from vehicles.
Fault memories in the vehicle can be reset by a
service outlet as part of repair or maintenance
work.
Depending on the selected equipment, you can
import data into vehicle convenience and info‐
tainment functions yourself.
This includes, for example:
Multimedia data such as music, films or pho‐

tos for playback in an integrated multimedia
system
Address book data for use in connection with

an integrated hands-free system or an inte‐
grated navigation system
Entered navigation destinations

Data about the use of Internet services

This data can be saved locally in the vehicle or it
is located on a device which you have connected
to the vehicle (e.g. a smartphone, USB flash
