If you have air in the ABS pump then you need a scanner that can cycle the pistons inside the pump to rid it of air bubbles. Some You Tube videos suggest going to a gravel road and getting the ABS to work a few times. I am dubious about that though but ....
When you bleed the brakes normally the pistons do not operate and I think the ABS is more or less bypassed.
