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

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‐

R ambient conditions (e.g. temp erature, rain

In addition tothe pr ovision of control unit func‐

malfunctions as well as tooptimize vehicle func‐

Only a small proportion of the data is stored in

When you use services, thete ch nical da tafrom

include repair services, maintenance processes, wa

which is requ ired bylaw. The respective service
network locations or third parties collect, process
and use the data. The data documents tech nical
