Abstract

A method for establishing at least one fault in connecting lines between electronic connection units and peripheral units, which are independent of one another, includes: outputting a start signal from the control unit to a first of the connection units, to start the establishment of the fault; applying a test signal to an interface of a first one of the connection units, the application of the test signal being monitored and/or controlled by a non-volatile first algorithm of the first connection unit; registering a cross-coupling of the test signal to an interface of a second connection unit and storing a fault value representing the cross-coupling in a first register, the registration and the storage of the fault value being monitored and/or controlled by a nonvolatile second algorithm of the second connection unit.
