Disclosed is a control unit circuit for a motor vehicle. The control unit circuit comprises a control unit and, outside a housing of the control unit, an electrical energy store for an emergency supply. To form an electrical circuit for the emergency supply, two electrical poles of the energy store are connected to the control unit via a cable and one of the two electrical poles is connected via a switching element to a ground potential of the on-board electrical system and at least one measurement circuit couples each one of the poles to the ground potential and is set up to generate a measurement signal, which is correlated with a voltage. If the respective measurement signal signals that the respective voltage is greater than a predetermined threshold value, the switching element is switched to an electrically non-conductive state.
