Abstract
The invention relates to a method for operating an electric circuit arrangement () which has a low-voltage sub-network () and a high-voltage sub-network (). A test signal is transmitted from one of the sub-networks () to the other sub-network () in order to detect a fault depending on the reception of the signal in the other sub-network () and to switch the circuit arrangement () to a safe state. A data bus (), which connects a low-voltage control unit () of the low-voltage sub-network () to a high-voltage control unit () of the high-voltage sub-network (), is operated with a maximum bus load at least temporarily as a test signal so that data packets are transmitted at fixed time intervals, and a fault is detected depending on a delay of the last received data packet, said delay being detected by the control unit () receiving the data packets.
