In a battery management system, during a pre-charge mode, a first contactor is closed to provide a pre-charge current path from a low voltage battery supply node through a DCDC converter and through the first contactor to pre-charge a capacitor of an inverter for an electric motor. During a drive mode following the pre-charge mode, the first contactor is opened and a second contactor is closed to provide a drive mode current path from a high voltage battery supply node through the second contactor to the inverter to power the electric motor. In response to detecting an open fault in the second contactor during the drive mode, a limp mode is entered. During the limp mode, the first contactor is closed to provide a limp mode current path from the high voltage battery supply node through the first contactor to the inverter to power the electric motor.
