ABS Automated bleed procedure
Anyone know of a DIY video for this procedure. I just got a TECH2 and have the factory service manual. I want to flush my system this winter and have a couple of questions. 1. How much fluid should I get? And 2. Do I have to run the atomated bleed procedure once or multiple times to flush the system clean. Thanks.

c5 brake bleed
I went through this procedure In May of this year when I removed the engine from my 2001. I had to disconnec one of the lines going to the Ebcm and I also replaced all four flexible lines to the calipers. At the time I did not have a Tech 2 so I just started bleeding the old fashioned way. started by opening the rr bleeder, lr, rf and lf bleeders. Had to pump the pedal to get the flow to start, but then just let gravity do its thing. I used a quart and a half of fluid and all fluid coming out was clean so I called it good. Brakes worked great with no sign of air in the system. I do not know of any videos using the tech2. hope this helps. Good luck with your repair. 
just for info the fluid drained out of th Ebcm while it was unhooked and it was mostly empty.

I have not done it yet with my Tech 2 but plan to this Fall. I have accessed it with the Tech 2 to see and it looks very straight forward. Do you know how to locate it?
Here is a great link that makes finding things in the Tech 2 easy.

You first flush the whole system manually by pumping and bleeding or using a pressure bleeder. I would use a syringe or turkey baster to suck the master reservoir empty before adding new fluid. Then, you use the ABS automated bleed procedure to get new fluid into the ABS pump and valves. The ASB bleed procedure will pump the old fluid from it's internal passages into the lines. I wouldn't worry about it too much because it's not very much fluid and you will never get all the old fluid out when you flush the brakes anyways.
The service manual says you'll need a quart of fluid so plan on at least that much.
