doubtful that bleeding the brakes would make any difference. possibly it is unplugged, possibly damaged during reassembly, possibly the ABS wire got caught on something and was damaged or is grounding out, possibly coincidence that another ABS sensor went out or the unit itself could be having issues. you may have to have the car scanned by someone with an ABS scan tool to determine the cause. make sure no fuses are blown and make sure the ABS module itself is properly plugged in as well as all ABS sensors at all the wheels.

 

Did you hook a scan tool up and see what code was coming up?
