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)
These data are exclusively technical
and help identifying and correcting
errors as well as optimising vehicle
functions.
Motion profiles indicating travelled
routes cannot be created with these
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 are deleted from
the error storage module or they are
constantly overwritten.
