  "textContent": "A controller of a drive system is configured to, when a power switch is changed from an on state to an off state in a situation in which it has been diagnosed that an abnormality is occurring in a motor generator, execute a starting check process of checking a drive circuit and an engine starting process of starting an engine. The starting check process includes a voltage reduction process of driving a DC-DC converter until a capacitor voltage becomes lower than or equal to a prescribed voltage. The controller is configured to, on condition that the controller determines through a voltage reduction determination process that the capacitor voltage is reduced as compared to the capacitor voltage at an end of the voltage reduction process, execute the engine starting process.",
