    Abstract: A vehicle and a method of reducing sound produced by a liquid fluid pump are disclosed. A pump is activated when a predetermined event is detected. A control valve of the pump is operated in one of an initial and a standard mode when the pump is activated. The control valve is operable to allow a gaseous fluid to vent out of the pump when in the initial mode corresponding to the pump being in a first phase. The control valve is operable to allow a liquid fluid to move through the pump when in the standard mode corresponding to the pump being in a second phase. A solenoid of the control valve is energized and de-energized, at a calibrated frequency, in a sequence when in the initial mode to reduce the sound in the pump during the initial mode.
