This is a fairly new reach truck with non-functioning tilt, side shift, and reach. The aux pump runs (though slowly, by the sound of it) and I can see one of the internal hoses take pressure, but still no function.

The diagnostic shows front and rear solenoids functioning, and no trouble codes have come up. I can't get the reach or tilt sensors to change from zero. And I can't really inspect everything because the pantograph is stuck in collapsed position. What wires and connectors I can see look OK.

Travel and lift/lower are fine. Any ideas would be appreciated.
