Re: 2001 grand cherokee...brakes

Welcome to the garage.
It is possible that air in the ABS hydraulic unit is causing the fault. The right procedure during bleeding is that a DRBIII scanner is used, which can activate the ABS pump, to get rid of trapped air in the unit. Did the light come on directly after switching ignition in run, or only during driving?
The ABS control unit performs a static test as soon as you switch the ignition in run. This is a test to see if any electrical faults are present. Then at a certain speed the dynamic test will be performed and the ABS pump will be cycled shortly. At that point trapped air could eventually set a fault. You could try to bleed it by braking hard, so that the ABS will be activated. (ofcourse on an empty road to prevent others test their ABS as well)
If any trapped air will come out, the brakes can become spongy due to the air in the normal brake lines, so you will have to manually bleed the brakes again.
Ofcourse the ABS fault light can be set due to an other problem, but only by using a scanner you will find out which fault is present.
