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‐

re qu irements and tech nical events or malfunc‐

In general, this information documents thest ate

Rinformation on vehicle damage events
Rsystem reactions in special driving situations
(e.g. air bag deployment, inter vention of sta‐

Rambient conditions (e.g. temp erature, rain

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

wo rkemplo yees or third parties. Services
include repair services, maintenance processes,

th e legally prescribed port for OBD ("on-board diagnostics") in
theve hicle. The respective
