Data storage modules in the
vehicle
A large number of electronic
components of your vehicle contain
data storage modules temporarily or
permanently storing technical data
about the condition of the vehicle,
events and errors. In general, this
technical information documents the
condition of parts, modules, systems
or the environment:
■ Operating conditions of system
components (e.g. filling levels)
■ Status messages of the vehicle and
its single components (e.g. number
of wheel revolutions / rotational
speed, deceleration, lateral
acceleration)
■ Dysfunctions and defects in
important system components
■ Vehicle reactions in particular
driving situations (e.g. inflation of
an airbag, activation of the stability
regulation system)
■ Environmental conditions (e.g.
temperature)
This data is exclusively technical and
helps identifying and correcting errors
as well as optimizing vehicle
functions.
Motion profiles indicating travelled
routes cannot be created with this
data.
If services are used (e.g. repair
works, service processes, warranty
cases, quality assurance),
employees of the service network
(manufacturer included) are able to
read out this technical information
from the event and error data storage
modules applying special diagnostic
devices. If required, you will receive
further information at these
workshops. After an error has been
corrected, the data is deleted from the
error storage module or it is
constantly overwritten.
