Ford Repair: 2001 Ford GT Mustang ABS Module, Ford, mustang

Question
I have a 2001 Ford Mustang GT that is giving trouble with the speedometer being off 15-20 miles per hour, the ati-lock brakes are not working and the ATS does not work.  Also the battery has a slow drain.  The Ford Tech says it is the ABS Module that is causing all of this.  Does this make sense?  Before I spend $900 on a new one which may not fix the problem, I want to know that this makes sense.

Answer
Lorrin,

Remove the front interior kick panels and see if the carpet matting is wet under the front carpet areas. A water leak intrusion in the 'A' post or roof panel areas can cause a condition such as this by entering into an electronic module. Let me know if you find the floor matting wet.
