traction control has a mind of its own.

So I have a 2010 peterbult 388, with factory traction control. It will apply a little brake for 1 second than let off than do it again. On off on off on off. doesn't do it all the time. it is pretty random. might not do it for a hour or so than will do it pretty steady. will do it at all speeds. It was doing it today at 65 with the cruise on. no codes, no lights, still does it with traction control switch off. weird.
It will also do it with the truck stopped and parking brake...
