If the ABS light is on then there is a fault in the anti lock brake system . This system monitor all the wheel speed and determines what wheels to apply the brakes to during a panic stop. The ABS light will have to be diagnosed by a qualified technican.

the rear one is a single sensor and is located in the top of the rear differential , unplug it and take the retaining bolt out and it pops straight up out of the differential. the front has 1 for each wheel,and is located on the backside of the wheel hub. take the tire off and look on back side of hub it should be the only sensor thare and is anchored with one bolt then just fallow the wire to its disconnect point. this vehicle is known to have problems with the rear sensor so i would replace it first and see if this fixes the problem

The ABS light is for the Anti-lock Braking System. The MIL will illuminate if there is a difference in wheel speed sensors signals to the PCM. So you might have a wheel speed sensor that is going out on you. Does the light come on at low speeds, or just higway speeds? You could take the vehicle to a local parts store and have them pull the codes for you and that will tell you which speed sensor is out of whack. Also road grime, dirt and gunk buildup can cause speed sensors to give false readings. Hope tihs helps you out.......

First question is: have you recently done, or had done, replacement of bearing hub assemblies or brakes? If so, check the wheel speed sensors on those wheel hubs. Second, look for the connectors, located less than 2 ft away from the hubs, and ensure they are snug. Much of the diagnostic work after the above has to be done by the dealer- these are of course complicated and sensitive systems. But there's no need in spending the cash unless you're sure it's a complicated breakdown.
