wheel speed, deceleration, lateral accel-
eration, engaged seat belt indicator.
– Ambient conditions, e.g., temperature,
rain sensor signals.
The processed data is only processed in the
vehicle itself while the vehicle is being op-
erated. Data is not stored beyond the oper-
ating time.
Electronic components, e.g. control units
and vehicle keys, contain components for
storing technical information. Information
about the vehicle condition, component us-
age, maintenance recommendations, events
or faults can be stored temporarily or per-
manently.
This information generally documents the
state of a component, a module, a system, or
the surrounding area, for instance:
– Operating states of system components
such as fill levels, tire pressure, battery
status.
– Malfunctions and faults in important
system components, for instance lights
and brakes.
– Responses by the vehicle to special
driving situations such as airbag deploy-
ment or engagement of the driving sta-
bility control systems.
– Information on vehicle-damaging
events.
The data is required to perform the control
unit functions. Furthermore, it also serves
to detect and correct malfunctions, and
helps the vehicle manufacturer to optimize
vehicle functions.
The majority of this data is stored tempora-
rily and is only processed within the vehicle
itself. In some circumstances the vehicle
may store some data for an additional but
limited period of time.
When servicing, for instance during repairs,
service processes, warranty cases, and qual-
ity assurance measures, this technical in-
formation can be read out from the vehi-
cle together with the vehicle identification
number.
An authorized service center or another
qualified service center or repair shop can
read out the information. The diagnostic
socket required by law in the vehicle is
used to read out data.
The data is collected, processed, and used
by the relevant organizations in the service
network. The data documents technical con-
ditions of the vehicle, which can be used to
determine vehicle maintenance status, and
facilitate quality improvement.
Vehicle fault and event memories can be
reset by an authorized service center or an-
other qualified service center or repair shop
when performing repair or servicing work.
Data entry and data transfer into
the vehicle
General information
Depending on the vehicle equipment, com-
fort and individual settings can be stored
in the vehicle and modified or reset at any
time.
For example, this includes:
– Settings for the seat and steering wheel
positions.
– Chassis and climate control settings.
If necessary, data can be transferred to the
entertainment and communication system
of the vehicle, for instance via smartphone.
This includes the following depending on
the respective equipment:
– Multimedia data such as music, films
or photos for playback in an integrated
multimedia system.
– Address book data for use in conjunc-
tion with an integrated hands-free sys-
tem or an integrated navigation system.
