Abstract
Methods of controlling a contactor in a high voltage electrical circuit of a vehicle include delaying a contactor opening if a valid open command is not received, inhibiting closing of a contactor if a low voltage circuit voltage is not sufficient to close the contactor, and determining a fault in the opening of a contactor based on voltages sensed on the contacts of the contactor.
