Brake differential pressure valve 200 1983

Just finished doing the front brakes on this (new rotors and pads) and flushing/bleeding the hydraulic system. After this little exercise the brake failure lamp will not go out, have good hard pedal so I feel I got out all of the air.

I am assuming there is a piston of some sorts in there that deflects to one side or the other if fluid pressure is not the same on both sides and it got set when I was bleeding.

Is there a way to "reset" this thing? The Haynes manual says to replace but I think unhooking the wires would be easier and cheaper! ;-)

Any suggestions?
