1995 Ford Aerostar

Brakes problem
1995 Ford Aerostar 6 cyl Two Wheel Drive Automatic 180000 miles

My ABS and brake light stays on and my speedometer doesn't work. I heard that this all ties in together, is that true? I have change the speed sensor and check the master cycler, wireing plug from the master cycler. I've heard that it may be the ABS control module. Where is that located? Is there a way to clear the code in the module.

Have you had the computer scanned to determine where the problem is coming from?
