What is wrong with Ford Escape Hybrid abs brake system when any door is opened?

I would guess that you are wondering about the noise the abs makes when you walk up to parked (engine off) Escape, and you open the door. You are hearing a hydraulic pump run to energize the high pressure accumulator (2200psi) that supplies the pressure to operate the hydraulic brakes. It takes a few seconds to build pressure, so Ford starts the pump when you open the door rather than waiting for the engine to start.
