Pump running all the time could cause voltage drop in the unit especially if battery is weak and that could result in communication errors.

So your guess would be the ABS module itself?
The first time I noticed the running pump after the car was shut off, was on NYE(Dec. 31). That was the first time. Haven't driven it since(well, I drove it home). I bought the car Dec. 27.
