Electronic control units are ins
talled in your vehi‐
cle. Some of them are necessary foryo ur vehicle
to function safel y,some pr ovide support when
driving (driver assis tance sy stems). In addition,
yo ur vehicle of fers comfort or enter tainment
functions which are also made possible with elec‐
tronic control units.
Electronic control units con tain data memo ries
which can permanently or temp orarily store tech‐
nical information on theve hicle's operating state,
component stre ss, service requirements as well
as tech nical events and malfunctions.
This information general lydocuments thest ate of
a component part, a module, a sy stem or of the
environment such as:
R operating statuses of sy stem components
(e.g. fluid le vels, battery status, tire pressure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, deceleration, lateral
acceleration, display of thefast ened seat
belts)
R malfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
R information on events in which theve hicle is
damaged
R system reactions in special driving situations
(e.g. airbag deployment, inter vention of sta‐
bility control sy stems)
R ambient conditions (e.g. temp erature, rain
sensor)
In addition tothe pr ovision of control unit func‐
tions, this data ser vesto recognize and rectify
malfunctions as well as tooptimize vehicle func‐
tions bythe manufacturer. Most of this data is
vo latile and is only processed in theve hicle itself.
Only a small proportion of the data is stored in
ev ent or fault memories.
When you use services, thete ch nical da tafrom
th eve hicle can be read out byservice network
emplo yees (e.g. workshops, manufacturers) or
th ird parties (e.g. breakdown services). Services
include repair services, maintenance processes, wa
rranty events and quality assurance measures,
fo rex ample. The data is read out via the connec‐
tion forth e diagnostics connection in theve hicle,
which is requ ired bylaw. The respective service
network locations or third parties collect, process
and use the data. The data documents tech nical
st ates of theve hicle, helps in finding er rors and
in impr oving quality and is trans ferred tothe
manufacturer if necessar y.In addition, the manu‐
fa cturer is subject toproduct liability. Forth is
purpose, the manufacturer requ ires tech nical
da ta from vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet during repairs or maintenance
wo rk.
Depending on the equipment selected, you can
enter data in com fort and inf otainment functions
of theve hicle.
This includes, forex ample:
R multimedia data, such as music, films or pho‐
to sfo r playback in an integrated multimedia
sy stem
R address book data for use in an integrated
hands-free sy stem or an integrated navigation
sy stem
R navigation destinations entered
R data on the use of Internet services
This data can be sa ved locally in theve hicle or
located on a device that you ha veconnected to
th eve hicle (e.g. smartphone, USB memory stick
or MP3 pla yer). If this data is sa ved in theve hicle,
yo u can dele teit at any time. Trans fer of this data
to third parties only occurs on your requ est,
especially as part of online services according to
th e settings you selec ted.
Yo u can sa vecon venience settings/cus tomiza‐
tions in theve hicle and change them at any time.
Depending on the equipment, this includes, for
ex ample:
R settings of the seat and steering wheel posi‐
tions
R suspension and climate cont rol settings
R customizations such as interior lighting
If yo ur vehicle is equipped appropriately, you can
connect your smartphone or ano ther mobile end
device totheve hicle. You can operate these devi‐
ces via the cont rol elements integrated in the
ve hicle. The smartphone's picture and sound can
be output via the multimedia sy stem. Simultane‐ 28
