Data stored in the vehicle
Electronic control units
Your vehicle is equipped with electronic
control units. Some of them are necessary for
your vehicle to function safely, some provide
support when driving (driver assistance
systems). In addition, your vehicle offers
comfort or entertainment functions which
are also made possible with electronic con-
trol units.
Electronic control units contain data memo-
ries which can permanently or temporarily
store technical information on vehicle con-
dition, component stress, service require-
ments as well as technical incidents and
faults.
This information generally documents the
condition of a component, a module, a system
or of the environment such as:
R
operating states of system components
(e.g. fluid levels, battery status, tyre pres-
sure)
R
status messages of the vehicle or its indi-
vidual components (e.g. wheel revolu-
tions/speed, deceleration in movement,
lateral acceleration, display of seat belts
fastened)
R
malfunctions and defects in key system
components (e.g. the lights and brakes)
R
information on incidents in which the
vehicle is damaged
R
reactions of the systems in specific driv-
ing situations (e.g. deployment of an air-
bag, use of stability control systems)
R
ambient conditions (e.g. temperature, rain
sensor)
