Ok so here is the problem between about 20 to 35 mph my abs starts cutting in for no reason, it does it a lot but not all the time, also it started this a few months ago and i replaced wore front pads and it was fine for awhile. checked the pads their ok front and rear. also if you stay on the brakesthe abs it cuts back off below twenty. is this a sensor??? or is it something else.

 

You mean the traction control? That would mean not all your wheels are turning at the same rate for some reason. If you drive in a tight circle do you get odd behaviour?

 

no it is only under braking and i feel it in the pedal.

 

I would check all 4 wheels, pads, and caliper pistons, sounds like you've got siezed calipers.

 

Short and sweet, you have an issues that only your ECU can answer. Find a small shop, not a dealer, that read the codes, write them down and ask to have them cleared to see if they will come back.
