Legal requirements regarding
data disclosure
According to current law, the vehicle manufac‐
turer is obliged to provide the authorities with any
data it has stored. Data is provided to the extent
required and on a case-by-case basis, for exam‐
ple to investigate a criminal offence.
The current law also gives state bodies authori‐
sation to read out data from the vehicle them‐
selves for individual cases. This could include
reading out data from the airbag control device
to shed light on the circumstances of an acci‐
dent, for example.
Operating data in the vehicle
Control devices process data to operate the ve‐
hicle.
This data includes, for example:
▷ Status messages relating to the vehicle and
its individual components, for example wheel
rotation speed, wheel speed, deceleration,
lateral acceleration, fastened seat belt indica‐
tor.
▷ Ambient conditions, for example temperature,
rain sensor signals.
The data is only processed within the vehicle it‐
self and is usually transient. The data is not
saved after the vehicle is switched off.
Electronic parts, for example control devices and
vehicle keys, contain components for storing
technical information. Information about the vehi‐
cle's condition, component use and wear, main‐
tenance requirements, events or errors can be
stored temporarily or permanently.
This information generally documents the condi‐
tion of a component, a module, a system or its
environment, for example:
▷ Operating states of system components,
for example fill levels, tyre inflation pressure,
battery status.
▷ Malfunctions and faults of important system
components, for example lights and brakes.
▷ Responses of the vehicle to particular driving
situations, for example triggering of an airbag,
activation of the drive stability control sys‐
tems.
▷ Information on vehicle-damaging events.
The data is required so that the control units can
perform their functions. It is also used for detect‐
ing and rectifying malfunctions, and helps the ve‐
hicle manufacturer to optimise vehicle functions.
Most of this data is transient and is only pro‐
cessed within the vehicle itself. Only a small pro‐
portion of the data is stored in event or error
memories in response to specific circumstances.
When service work is being carried out, for ex‐
ample repairs, service operations, warranty work
and quality assurance measures, this technical
information can be read out from the vehicle to‐
gether with the vehicle identification number.
A Service Partner of the manufacturer or another
qualified Service Partner or a specialist workshop
can read out the information. The data is read
out via the on-board diagnostics (OBD) socket,
which the vehicle is required to have by law.
The data is collected, processed and used by the
relevant organisations in the service network.
The data logs the technical conditions of the ve‐
hicle and helps in locating errors, complying with
warranty obligations and improving quality.
Furthermore, the manufacturer has product
monitoring obligations to meet in line with prod‐
uct liability law. To fulfil these obligations, the ve‐
hicle manufacturer requires technical data from
the vehicle. Data from the vehicle can also be
used to check customer warranty claims.
Error and event memories in the vehicle can be
reset when a Service Partner of the manufacturer
or another qualified Service Partner or a special‐
ist workshop performs repair or servicing work.
