Re: ... this... This... THIS... THIIISSSSS!!!
ABS=anti-lock braking system. If you didn't know, there are sensors at all 4 corners that prevent the wheels from locking up and the vehicle loosing control.
if your light is on it means that something is faulty within that system and will not function properly, could just be a bad sensor or connection, a good diagnostic tool can determine. Many of us are staring at that light and as I said, my lights been on since I had new rotors and a free spin hub kit installed, I'm not too concerned, but will someday get it diagnosed and depending on what the issue is, get it fixed.
