This happens because the sensors on the wheel (or the wiring to them) were damaged by the stone chips thrown by the wheels.
Lift the front of the car, take the wheels off and check them. You should also check the error codes, you might have some other problems that were caused by the faulty wirings.

    In that case the PCM (which controls the ABS) is malfunctioning and must be replaced.

I have 1998 gmc 3/4 ton auto . a.b.s light comes on intermitantly. when it does I also loose my full heater controls and cruise control. new brake switch has been instaled but c'ant see how that would


It is coincidence that your heater control went at the same time your ABS control went out. Try replacing the ABS control and see if that fixes it. Many times because of the electrical complexity you have to just start replacing things until you get it unless you own one very expensive computer.
Look for loose wires. Also try it in reverse if you like. Replace the heater control and see if that fixes it all. Also check ALL fuses.

ABS and brake light comes on when truck is driven brakes are at 70% and work fine just lights come on on message center after truck is driven about 5 min's. truck is a 2001 gmc 1/2 ton sierra with 119k...


If you have recently bought new tires and the size is larger or smaller than the stock tire size, it will throw off the ABS as the computer thinks the tire is not running at the correct programmed rpm in relation to the overall truck speed. Check with a local tire shop to have it checked.

2001 GMC SIERRA . ABS LIGHT STAYS ON


Wheel speed sensors misadjusted, damaged , or metal shavings and other debree, since they are magnetic can give false readings from one of the wheel circuits. Over sized tires can give of false speed readings as well. there are many other causes including bad relay, control module, e.t.c. It is best to have the proper scan tool to diagnose an ABS problem
