I have a 1993 3 liter Aerostar with 93,000 mi. that has an issue in the ABS Rear Barake Sensor. I have had the system checked at a garage and they found now problems in the lines from the Master Cylinder to the rear cylinders. After inspection, I was told that it is an issue in the Control Module. I found the part in a local parts store and want to replace it. Will I have to go through and run an entire brake bleed when the module is replaced? I would think that I would not have to considering there is no line that goes into the back of the controler. It should just be the plug that goes into the module that regulates the Hydrulic Unit, correct?
