I hate answers of "I don't know", but there you go. I removed my whole ABS system when I swapped axles. It had disks and I just put a PV from a 98 Grand in. I have not had any problems with taking mine out. I kept all my part incase I needed to figure something out, but I don't have any codes or lights. I just cut my wires and hey are still just hanging there. I thought it was just a alarm incase one of the valve circuits failed. It would give you a break light so you would no one of the front or rears was not working.
Also, I ran into a lot of problems mixing and matching. Was not prepared for that. The fittings look similar but are not. I wound up having to use the old fittings and made new lines. So if the prop valve is from the same MC you are swapping, you are in buisness. If not be prepared.
