ABSTRACT:
Multiple embodiments relate to a method for detecting a fault on a data line in a bus system in a two-line data network having at least two control units. A data signal is emitted by a transmitter-receiver unit on the two data lines as a differential voltage signal that includes a defined quiescent current. The data lines are mutually connected through a resistance bridge for detecting the middle voltage. The middle voltage is detected directly by a microcontroller after a low-pass filter or as a digital value after an analog-to-digital conversion. The result is displayed and/or stored. A circuit arrangement for implementing the method is also provided.
