The ABS system does a self check at about 10kph. Above that speed a problem will be recognized as a fault and the system is shut down. Up to that speed the fault won't shut the system down and they will be reacted to. The pulsing at slow speeds is a bad sensor input being interpreted as a wheel lock up and the pulsing is applied to stop it. If the fault is still there after 10kph the system shuts down and the light is turned on.
