A warning light only warns that there is a problem, it doesn't point out exactly what the problem is. The system will need to be inspected and diagnosed to determine the fault. Diagnosis could be from 1-2 hours up front, then more for repairing the problem.

I have a 2000 Mustang with the same symptom at 97k miles. A mechanic has to retrieve the error codes from your on-board computer, this will reveal where the problem lies. I paid $50 for the diagnosis, it took about an hour. Unfortunately I have a bad ABS control unit which is about $700 from the dealer, you can add 2 to 3 hours labor to that.
