Take you feet off both footpedals and after a few seconds the Calibration option should appear while you're scrolling through.

Yes we have removed the right tilt cylinder. The tilt sensor need to be calibrated.

The tilt position sensor (RPS2) is above or below the calibrated range. Did you remove the right hand cylinder as you stand on the truck facing the mast? Thats the one with the tilt position sensor. Maybe you didn't engage the potentiometer arm correctly. You can check RPS2 voltage in Analzyer menu A2.4.8.1, 2.2v = 5deg fwd tilt, 2.8v = mast vertical, 3.3v = 5deg back tilt.

RPS2 can be calibrated in Menu item C2.1
