Bleeding ABS Module

Bleeding ABS Module I swaped calipers on all four corners of my car, the car sat for about a month on jack stands so I know all the brake fluid drained out. I installed all the brakes now & have bled them three times & they are still real soft. My concern is the ABS Module was empty meaning it needs to be bled also. Is there anyway to do this without a Tech2?

Bleed it to the best pedal you can get. Put it together & drive it.
At 15 mph the ABS will do a self test & cycle the dump valves.
Then take it back & rebleed it again. All the air should now be out.
You have to drive it though, there's no fooling it.

Oh, and I hope that you can get them bled before tomorrow. The drive from Springville to Trussville would suck with no brakes.

You need to drive it for a couple a min at least. Get it up above 15 though. That is the threshhold MPH.
As for scanners the snap-on newer 2 the modus & solis are supost to do bleeding on the newer delco systems.
