A control device for a multi-voltage electrical system of a vehicle is provided. The multi-voltage vehicle electrical system includes a first subsystem which is formed to be operated by a first voltage supply source with a first supply voltage, and a second subsystem which is formed to be operated by a second voltage supply source with a second supply voltage. The control device comprises: a transceiver which is connected to ground via a first ground terminal of the first subsystem and is supplied with energy at least by the first voltage supply source, and which is formed to communicate with a component of the first subsystem; a control unit which is connected to ground via a second ground terminal of the second subsystem, and which is formed to control a component of the second subsystem. The control unit is supplied with energy at least by the first voltage supply source.
