2007 Camry Hybrid ABS Problem

[dmb7011]

I have an "air" hissing sound coming from the ABS controller (pump) located between the wiper fluid tank and the radiator overflow tank at right front under the hood. The Number on top of this part is 44510-30270 TOYOTA 1QB02 - 106. The "pump" cycles on about every 5 seconds, runs about 5-7 seconds, then cycles off, but the hissing sound continues. When I push on the brake pedal, the hissing sound becomes muted but the pump continues to cycle. ABS and/or brake warning lights are NOT on (however the tire pressure light came on about the same time the hissing started)... Any ideas?
