Abstract
The invention relates to a method for operating a motor vehicle () which has an electric high-voltage network () and an electric low-voltage network (), wherein the high-voltage network () has at least one traction battery () and at least one electric drive machine (), the low-voltage network () has a vehicle electrical system battery (), and the high-voltage network () is monitored for an electrical short-circuit and, upon detection of a short-circuit, the traction battery () is disconnected from the high-voltage network (). According to the invention, in order to check the plausibility of the detected short-circuit before the traction battery () is reconnected to the high-voltage network (), a boost current (I) is applied to the high-voltage network () through the low-voltage network () by means of a DC/DC converter (), and a boost voltage (U) measured in the high-voltage network () is compared with an expected boost voltage (U).
