An arrangement for a motor vehicle includes a master controller and a slave controller that use different reference-earth voltages and respectively comprise a transmission and a reception unit for shared data interchange. The transmission and reception units are connected to one another via a shared communication line. The communication line contains a diode that prevents a flow of current from the slave controller to the master controller. The master controller contains a pull-up resistor via which the shared communication line can be connected to a first reference-earth potential of the reference-earth voltage of the master controller. |
