Ok. I regret to tell you that you will need to visit the dealer to bleed the ABS. There is a function of the scan tool that cycles the valves, solenoids and pump in a sequence that releases trapped air. I have watched skilled techs waste several hours trying to bleed these without the scan tool and get no where.
