Antilock Brake Problem

I have been trying to figure out why my antilock brake light has been on. Currently I have rebuilt the front and rear brakes, I have bled the brakes and cleaned all of the wheel speed sensors. I just purchased this car last weekend and the light was on when I bought it. I ran the codes on the antilock system and it shows that the right front inlet valve, is the problem. Is there anything I can do or is it replacement time? I am assuming that it is the control that is located above the propotioning valve. Is that correct as well? Thanks Sean

Pull the 7 connector off the top of the valve block. Measure resistance from pins 1 to 7 (end pin to end pin), which are the terminals for the RF inlet valve. Resistance should be in the 3 to 5 ohm range. If it is 0 ohms or infinite ohms, the solenoid is bad. If that is the case, the entire MC sssy needs to be replaced, as the valve block cant be serviced.

I just checked between pins 1 and 7 and had 7.0 ohm's. What pins are what? I do not have a wiring diagram for the ABS. Evidently I was incorrect on the right front valve code. Thanks.

I will ask again, what pins out of the seven serve each solenoid? What else is there to look for. Does anyone have a wiring diagram of the ABS system on an 87 TC? Thanks Sean
