How to bleed ABS Module Under the Hood

[hoorders]

Hey everyone, Can anyone walk me through bleeding the ABS module/contoller that sits on my drivers side fender well? Its for my 93 Yukon. There are 2 bleeder screws on it side by side. I changed the brake pads on the truck the other day and when I put it back together the ABS and brake light were on in the dash. Im thinking that when I pushed the caliper in, it did 'something' in the module. I have already bled all the brakes.

 

Thanks.

Air in the system will not cause the red brake or abs lights to come on. Probably have a wheel speed sensor gone on the fritz. Chalk it up to coinsidence more than likely.
