GENERAL INSTRUCTIONS
or specialist workshop read out
the data stored in the vehicle
for a fee if required.
The vehicle data is read out via
the vehicle's legally mandated
diagnostic socket.
Legal requirements for the
disclosure of data
The vehicle manufacture is re-
quired by the law applicable in
this context to provide authori-
ties with the data stored by the
manufacturer. The provision
of this data within the scope
required is on a case-by-case
basis, for instance to clarify a
criminal offense.
Government agencies are au-
thorized by the law applicable
in this context to read out the
data from the vehicle them-
selves in individual cases.
Operating data in the vehicle
Control units process data so
that the vehicle can run.
Examples of this include:
Status messages from the ve-
hicle and its individual com-
ponents, such as wheel RPM,
wheel centrifugal velocity and
deceleration
Ambient conditions, such as
temperature
The data is processed only in
the vehicle itself and is usu-
ally temporary. The data is not
stored beyond the period in
which the vehicle is operating.
Electronic components such
as control units contain com-
ponents for storing technical
information. This may be infor-
mation about the vehicle's con-
dition, component load, events
or faults stored temporarily or
permanently.
This information generally doc-
uments the condition of a com-
ponent, module, system or the
surrounding area; for example:
Operating conditions of sys-
tem components, such as fill
levels and tire pressure
Malfunctions and faults in key
system components, such as
lights and brakes
Vehicle responses in specific
riding situations, such as the
activation of riding dynamics
systems
Information about events
causing damage to the vehicle
The data is necessary for pro-
viding control unit functions. In
addition, it is used by the vehi-
cle manufacturer to detect and
eliminate malfunctions as well
