Pump1 has a load sensing priority valve on the bottom. steer always gets priority. That being said, the contorller monitors amp draw from motor. the amps on the motor will go up with more hydraulic demand if the pump is good and building proper pressure. If pressure is not loading down the motor it will not speed up to move the volume needed to properly steer and/or run accessories. I just replaced a pump 1 on a 5200 monday due to this issue, only mine was "strong arm" steering due to not enough hydraulic pressure from the motor not speeding up with hydraulic demand.

Update: Sorry just notice this is a really old post... Dont know how I ended up this far down on the threads! lol But I will leave my note here for others.

It's all just nuts n' bolts.
I checked the motor through access 1 and the idle speed is lower than aonther unit i compared it to, what would cause low hydrualic pressure, and motor dosent seem to kick into high speed when using accessories or steering

f254 is calibration timed out
how does lift pump and motor seem?
the list is quite long of possibilities but leans towards low hydraulic pressure.
