Could possibly have a bad connection on a wheel speed sensor. This would cause an erratic reading making the ABS light come on because the system thinks a wheel is either slipping or dragging.

Yes it is possible that you have a bad wheel bearing which has the abs sensor in it. Hence the abs light on. Traction control utilizes the abs as inputs therefore traction control will come on.

2008 Escape has a terrible reputation for ABS light and traction control light being. All due to broken ABS tone ring cracked and out of position flopping on frt bearing. Go to local AutoZone store and they will scan this to find which wheel has the broken tone ring. The replacement ring is cheap in the $7 range. It is labor that will sicken you as this ring must be pressed on after the front half shaft is removed. Not a driveway job if you are considering DYI.

2002 Buick Rendezvous Service traction system and ABS lights, grinding when turning ans braking


The ABS and Service Traction system may be due to bad sensors or signal reaching the ABS/Traction Control computer. The grinding may be due to uneven or unsmooth rotors, and/or worn out pads or shoes.

I would recommend that the entire braking system be diagnosed at your local dealer or brake service facility.

Brake sensor? something else?


You have a faulty wheel speed sensor. This is a magnetic pick up sensor on your wheel bearing hub and it controls your abs. If the car can not sense all 4 wheels then the abs will default back to normal brakes and your traction control will not work. Look at your wheel bearing hubs and check for these sensors. They are on the underside of the car and are black plastic with a wire comming out of it. A piece of gravel may have broken the pick up or the wires to a sensor may be broken as well. To replace it is usually a couple of screws on the hub assembly and a plug to disconnect from your wire harness.
