Ve hicle data storage
Information from electronic control units
Yo ur vehicle is equipped with electronic contro l
units. Some of these are necessary forth e safe
operation of your vehicle, while some assist you
when driving (driver assis tance sy stems). In
addition, your vehicle pr ovides con venience and
enter tainment functions, which are also made
possible byelectronic 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, mainte nance
re qu irements and tech nical events or malfunc‐
tions.
In general, this information documents thest ate
of a component part, a module, a sy stem or the
sur roundings, forex ample:
Roperating statuses of sy stem components
(e.g. fluid leve ls, battery status, tire pressure)
Rstatus messages concerning theve hicle and
its individual components (e.g. number of
wheel revo lutions/speed, decele ration, lat‐

eral acceleration, display ofthefast ened seat
belts)
Rmalfunctions or defects in impor tant sy stem
components (e.g. lights, brakes)
Rinformation on vehicle damage events
Rsystem reactions in special driving situations
(e.g. air bag deployment, inter vention of sta‐
bility control sy stems)
Rambient 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 malfunctions and opti‐
mizing vehicle functions. The majority of this
data is temp orary and is only processed in the
ve hicle itself. Only a small portion of the data is
st ored in theeve nt or malfunction 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 malfunctions and impr oving quality and are
transmitted tothe manufacturer, if necessar y.
Fu rther more,
the manufact
urer is subjectto
product liability. Forth is, the manufacturer
requ irestech nical da tafrom vehicles.
Malfunction memories in theve hicle can be
re set bya service outlet as part of repair or
maintenance work.
They can enter data into theve hicle's con veni‐
ence and inf otainment functions themselves as
part of the selected equipment.
This includes, forex ample:
