94 RABS Help

[Lakota]

My RABS light started coming on after I replaced the left rear wheel cylinder. I completely flushed the brake lines to make sure that I go any air out and I cleaned off the rear ABS sensor and this didn't do any good so I replaced it and it is still on.
I need to know what I should look at next either the Hydraulic Control Unit or the Control module. I am leaning toward the control module because looking at the wiring schematics that are in the Haynes manual it shows that Control Module is somehow connected to the Cruise Control and this is also not working. Any help or insight on this would be appreciated. I need to get this done quick because the snow is starting to fly and it is no fun with the rear wheels locking up.

I am pretty sure there is a bleed screw on the ABS valve. Did you bleed it there? It could also be the sensor on the rear axle. The sensor is called the RABS sensor. Sometimes you can take it out and clean it.

I didn't know that there was a bleed screw ABS Hydraulic valve and don't remember seeing one when looking at it. Where is it at??? Top,bottom, or sides??? I have replaced the sensor that is on the rear axle so it shouldn't be that unless the new one is faulty. The part that is strange to me is that the ABS light doesn't come on until I reach about 20mph and I don't even hit the brakes it just comes on.
