Go vernmental entities are themsel ves, in individ-

This is data rega rding the operation of theve hicle,

This includes thefo llowing data, forex ample:
R vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revo lutions or thefa stened
seat belts display R
ambient conditions, su chastemp erature, rain
sensor or distance sensor
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
fo rve hicle keys,fo rex ample. Their use permits
th ete mp orary or permanent documentation of
te ch nical information about theve hicle's operat-
ing state, component loads, main tenance requ ire-
ments and tech nical events or faults.
Depending on theve hicle equipment, thefo llo w-
ing data are stored:
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
R system reactions in special driving situations,
such as airbag depl oyment or the inter vention

If yo u use services, such as repair services and

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
