The processed data is only pro-
cessed in the vehicle itself and
generally volatile. The data is
not stored beyond the operating
period.
Information about stored or
exchanged data can be
requested from the manufac-
turer of the vehicle, in a sepa-
rate booklet, for example.
Electronic components, e.g.
control units and ignition keys,
contain components for storing
technical information. Informa-

• Responses by the vehicle to
