December 9, 200718 yr Hey Guys.... I have a 96' Legacy AWD Sedan ej22 with a 5spd.... my ABS light has been on....I pulled 3 flash codes for it....The first two were open sensors which i can look into, but the 3rd code said there was a "VALVE RELAY PROBLEM" code #51...I did a few searches on here and a few other forums and cant seem to find any information on it.....If anyone has anything on this issue it would be very helpful.
December 9, 200718 yr The "valve relay" is the relay in the ABS control module that controls power to the inlet and outlet solenoid valves for all of the wheels (those are what cause, by rapidly opening and closing, the brake pulsation when ABS is activated). The FSM tests are first for good ground and power supply; if necessary, harness or connector contacts are to be repaired. If those check okay, it's apparent that Subaru doesn't want anyone to go inside the control module or hydraulic unit, since the procedure otherwise leads to "replace ABSCM&H/U".

December 9, 200718 yr I did lower the car...someone told me that doing that could mess up the whole system....do u know if that is true?Without knowing exactly what you did, it would be hard to say for sure. Certainly if any wiring is being stressed or could be chafing against something, that might explain some of the problems you've mentioned.
