An electrified vehicle includes an active discharge system having a plurality of resistors connected in parallel, a switch connected in series with the plurality of resistors with the switch and the plurality of resistors connected across positive and negative legs of a high-voltage DC bus, and a controller coupled to the switch and programmed to close the switch in response to a vehicle shutdown signal, and in response to voltage of the DC bus exceeding a first threshold after a predetermined elapsed time from closing the switch, open the switch. The controller may also open the switch when the voltage of the DC bus is below a second threshold.
