Claim Text:
1. A method for establishing at least one test fault in connecting lines between a plurality of electronic connection units and a plurality of peripheral units, the peripheral units being independent from one another, the connection units being controlled by a volatile algorithm programmed into a control unit, and the connecting lines between the peripheral units and the connection units being each implemented with the aid of at least one two-wire line, the method comprising: outputting a start signal from the control unit to a first one of the connection units to start the establishment of the fault; applying a test signal to an interface of a first of the connection units, wherein the application of the test signal is at least one of monitored and controlled by a nonvolatile first algorithm programmed into 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, wherein the registration and storage of the fault value is at least one of monitored and controlled by a nonvolatile second algorithm programmed into the second connection unit; and reading out the at least one fault value by the control unit at least from the first register to establish the fault in the connecting lines between the first connection unit and the plurality of peripheral units.
