Method and device for establishing a fault in connecting lines between a central unit and a plurality of electronic components which are independent of one another

摘要

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.

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.
