anti lock brake light problem

My son's 99 V-8 grand cherokee has developed a problem with the anti lock light occasionally coming on and staying on until the engine is turned off. The light may come back on or stay of when the jeep is restarted. Other times the light will come on and then go off quickly for no reason. Otherwise, the brakes appear to be fine.

How serious is this light problem and what could be the cause?

The light being on and detecting a problem, will not affect the normal braking operation of the Jeep. Could be a dirty wheel sensor that is not sending a signal, to a faulty unit.
Dealer scan tool would pinpoint the problem area, but you might want to spray clean all the wheel sensors if you feel energetic.

If there are alot of sand/dirt on the sensors, that will throw off the magnetic/inductive response, and think there is a problem.

Remove the wheel and just clean the area with water.....

I say no on using any solvents.
