hicle data storage Information from electronic control units
Electronic control units are
fitted in your vehicle.
Some of these are necessary forth e safe opera‐
tion of your vehicle, while some assist you when
driving (driver assis tance sy stems). In addition,
yo ur vehicle pr ovides con venience and enter tain‐
ment functions, which are also made possible by
electronic control units.
Elect ronic control units contain da tamemories
which cantemp orarily or permanently store
te ch nical information about theve hicle's operat‐
ing status, component loads, main tenance
re qu irements and tech nical events or faults. In
general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings such as:
R operating statuses of sy stem components
(e.g. fluid le vels, battery status, tyre pres‐
sure)
R status messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, decele ration, lat‐
eral acceleration, display of thefa stened seat
belts)
R malfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
R information on vehicle damage events
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 toprov iding the actual control unit
function, this data assists the manufacturer in
de tecting and rectifying faults and optimising
ve hicle functions. The majority of this data is te
mp orary and is only processed in theve hicle
itself. Only a small portion of the data is stored
in theeve nt or fault memor y.
When your vehicle is serviced, tech nical da ta
from theve hicle can be read out byservice net‐
wo rkemplo yees or third parties. Services
include repair services, maintenance processes,
wa rranty events and quality assurance meas‐
ures, forex ample. The read out is per form ed via
th e legally prescribed port for OBD ("on-board
diagnostics") in theve hicle. The respective
service network locations or third parties col‐
lect, process and use the data. They document
te ch nical statuses of theve hicle, assist in find‐
ing faults and impr oving quality and are trans‐
mit tedto the manufacturer, if necessar y.Fu r‐
th ermore, the manufacturer is subject toprod‐
uct liability. Forth is, the manufacturer requ ires
te ch nical da tafrom vehicles.
Fa ult memories in theve hicle can be reset by a
service outlet as part of repair or maintenance
wo rk.
They can enter data into theve hicle's con veni‐
ence and inf otainment functions themselves as
part of the selected equipment. 28
