The ABS pump is what the ABS module turns on when the system needs to modulate the brakes during an ABS event/stop. If a wheel speed sensor shows a wheel slowing down to quickly or "thinks" a wheel is slowing down too quickly, then that pump will be activated and you will hear it come on and the pedal may pulsate. The pump is not the problem, it is a brake rotor or wheel speed sensor.
