Hello
OK, point by point:

L203 - Error detected on reach potentiometer (check the pots in carriage)
L205 - Error detected on sideshift potentiometer (as above)
L213 - height encoder error - no encoder signals at reference point
L279 - ? (I found 279 error in steering: reading of the drive unit pot and the unit actual position - it may stop the truck)
L478 - Safety controller error lift motor RPM tests
L264 - truck turned off whilst above the reference sensor (ignore it)
L217 - height encoder does not respond correctly while lifting/lowering
L218 - Lift slowdown detector not detected

Hope it helps.
