Hi all,

I have abs pressure switch fault 123 showing on hawkeye. I have changed the pressure switch on the pump, the brake light switch aswell. The pump runs as should . If I clear the fault it returns on engine start up .

Any help in where to go from here would be much appreciated

could be your accumulator failing and because it takes long to build pressure, maintains low pressure and over all under performs, the switch reads and reports low pressure.
an easy test, build pressure, proceed to pump brakes at about the 3rd pedal push the pump should activate briefly to compensate and then stops.
that is the easy way, I think there is a complete procedure on the search section, definitively in the rave.
