I guess then you'll be buying a valve.They're 160 something at NAPA,plus 30 something for the core.Then,after the valve there's the module,which according to that thread I posted,can throw false codes.
I have'nt by-passed mine YET.I took the annoying abs bulb out,but forgot that the abs light will trigger the red brake warning light also,which I presently have now-although the brake system is good-except for the fact that I read a code translating to excessive accuation of dump valve.Which,if I'm interpreting the operation of this valve in supplied literature correctly,that's what it is supposed to do-dump pressure so the wheels don't lock during braking.
So essentially what I'm saying (not saying this IS your problem,but might be- same as mine),the abs valve is in fact doing it's job,but the module is reading the dump valve accuating as a fault.
