Default Brake Bleed Questions

Ok, long story short I broke a brake line and dumped all of the fluid. I know that I have air in the system because the reservoir went dry. So will a standard brake bleeding procedure take care of my issues or do I need to to and ABS bleed as well? Is there any way for the DIY'er to do a ABS bleed without the scan tool? I never hit the brakes once I realized that the line was broken and the car was only started to get it on and off the trailer then into the garage so I doubt the ABS was ever active. It's my understanding from the service manual that the valves should be closed under normal opperation so I thinking that I don't need to do an ABS bleed????

You should be fine just doing a standard bleed, I like to use a power bleeder then go back and do a gravity bleed.

The EBCM does turn the pump on for a moment when the engine is started as a test. I do not know if the valves are opened during this test.

According to the service manual, if air is introduced upstream of the ABS, an automated bleed is required. Since the reservoir went try, this would qualify for an automated bleed.

So is there anyway to do the ABS bleed with out having to go to the dealer? I did the wheels tonight and the car seems to have a real firm feel. Haven't gotten it out of the garage yet but it feels pretty good on the stands. What would be a symptom of air in the abs?
