R vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revo lutions or thefa stened

R ambient conditions, su chastemp erature, rain

Generall y,the use of these data is temp orar y;
th ey will not be stored be yond the period of oper-
ation and will only be processed within theve hicle
itself. Control units oTen contain data memories

th ete mp orary or permanent documentation of
te ch nical information about theve hicle's operat- ing state, component loads, main

Depending on theve hicle equipment, thefo llo w-

R operating status of system components, such
as /ll le vels, tyre pressure or battery status
R malfunctions or faults in impor tant system
components, such as lights or brakes

In cer tain cases, it may be requ ired tostore da ta

de tected a malfunction, forex ample.
If yo u use services, such as repair services and
maintenance work, stored operational data as

re ad out and used. They can be read out by
service network emplo yees, such as workshops
and manu facturers or third parties, such as break- down services. The same is true in
the case of
wa rranty claims and quality assurance measures.
In general, there adout is per form ed via the legally
prescribed port forth e diagnostics connection in
th eve hicle. The operational data that are read out
document tech nical states of theve hicle or of
individual components and assist in the diagnosis
of malfunctions, compliance with warranty obli ga-

data, in particular information about component
loads, tech nical events, malfunctions and other
fa ults may be transmitted along with theve hicle
identi/cation number tothe manufacturer. Fur-
th ermore, the manufacturer is subject toproduct
liability. Forth is reason the manufacturer also
uses operational data from theve hicle, forex am-
