Help: Air in ABS after brake flush
Discussion
I just flushed my brakes for the 5th or 6th time since I have had my 2009 Vantage. This time I got distracted and let the fluid run out on the last wheel (FR), subsequently I have flushed almost 2 liters and still have a soft pedal. Unfortunately there is no dealers withing 3 hours of my location in Jacksonville, FL
1. I have researched for any diagnostic tool Foxwell, etc that can cycle the ABS module, without luck. Is there anything other than a AMDS system that can do it. Seems available for almost any other vehicle! I have read feedback from one Foxwell NT 530 with add on foxwell Aston software that the unit support ABS cycling but has not done so. I have reached out to Foxwell chat (and email) in attempt to verify it it truly has that capability. Obviously reading the ABS module is not sufficient if it can not perform activation of the system.
2. I have read some that suggested to have the rear wheel spinning ( I have a lift and can do safely) and hit the brakes to activate the abs then rebleed the brakes.
I have both pressure bleeding and vacuum bleeding equipment that I typically used. If the #2 solution works, I will use both. I have not used pressure and vacuum together but matter as well try.

Have you tried bleeding the master cylinder, bleed screw is under the reservoir.
If you haven't ignition cycled your car whilst you have air in the brakes, the wheel off the ground trick won't do much other than potentially put air inside your module. That works by tricking the system that you are in ABS and actuating the valves to bleed normally closed parts of the circuits inside the ABS module. A soft pedal with no ignition means air is in the normally open parts of the circuit.
