ABS problem

Today going home my ABS started working while braking up to a stop sign on the pavement? Okay really wierd...so i did some testing and figured out that my ABS is pulsing the brakes only between 50-15 mph...if im going 60 and start to brake it works fine till i get to 50 and then starts to kick abs and pulse my brakes...does that till 15mph and then stops and brakes normal again...

WTF does this mean...no codes for it...

I think the sensors might be dirty. The rear pumpkin sensor is the easiest so start with that one, the speed sensors in the front hubs are a little bit trickier, they require allen keys.

Yup, it sits right on top of the diff housing (some call it the pumpkin) and it is usually the culprit when abs problems arrive. Try wiping it off with a rag, re-install and test the brakes again.
