A method for handling a faulty device in a vehicle communication network
is provided, which is used to identify devices that are either faulty,
were removed from the vehicle communication network or were switched off,
and to automatically initiate a fault-remedying measure. An expanded,
device-specific driver having diagnostic functions is loaded by another
device of the network to send a test signal to the faulty device. Either
the faulty device is restarted or the faulty device is switched off
depending on the reaction to the test signal. If a device is removed from
the network, this is indicated in a database. A bus manager will inform
other devices connected to the network that this device was removed from
the network. Due to a classification of the individual devices connected
to the network, not every device is able to perform the fault handling,
but rather only suitably classified devices. Misuse is thereby prevented.
