You never did say what you'd meant when you said the ABS module had been disconnected. The electrical connector? The brake lines? Everything?
If the electrical connector has been disconnected, try taking it back off, cleaning out any debris if necessary that couild be preventing good electrical connections, re-seating it, and tightening it again. The #43 code you mentioned refers to a shorted or disconnected coil/wiring, which an improperly seated connector could be causing.
Once you get the electrical connector checked and reseated, you can also try removing the 40 Amp ABS fuse, then starting the engine to see if the brakes start working (brake pedal moves) even though ABS won't be functioning.
Since you haven't specified HOW the ABS had been disconnected, it's difficult to narrow the problem down to being possibly electrical or mechanical in nature, and seeing as how you say the battery had also been disconnected, it could still be either.
