A method for determining a current capacitance value of a Y capacitance of an electrical wiring system for an electrically operated motor vehicle by an electronic computing device where a high-voltage energy store of the electrical wiring system is electrically coupled with an energy store-external part by a switching device. In an energy store-internal part of the electrical wiring system, determining a first insulation resistance on a basis of a capacitance value of the electrical wiring system by a first insulation monitor. Determining a second insulation resistance of the electrical wiring system by a second insulation monitor of the energy store-external part. Comparing the first insulation resistance with the second insulation resistance by the electronic computing device. On a basis of the comparing, adjusting the capacitance value for determining the first insulation resistance by the first insulation monitor such that the first insulation resistance matches the second insulation resistance.
