Next step for me would be take out the fuse for the ABS system. Then drive the car a few days and see what behavior your get.
 
If behavior had disappeared then reinsert fuse and have checked to see which input sensor is giving wrong impulse.

I believe the Tech II or a few other units that are similar can actually cycle on the ABS pump as a way of bleeding it.
