The electronic control unit includes first and second power connectors, first and second ground connectors, first and second inverters, first and second control circuits, and first and second current-voltage conversion elements. Each current-voltage conversion element is provided between a ground of the corresponding first or second inverter and a common ground of the first and second control circuits, and measures a ground current of the corresponding first or second control circuit. Then, each control circuit determines that the corresponding first or second ground connector is in an abnormal state based on a current flowing through the corresponding first or second current-voltage conversion element.
