Error code for Ls170 NewHolland skid steer?

Hello,
I have issue with a New Holland Ls170 Skid steer
The machine came to me with no hydro controls or movement (no drive no boom lift or bucket)
the hyro pump seems to be working though waiting on a hydro test unit to arrive.
This started when it was driven into a pile then just stoped workeing
there is only one error code coming up of F04?
since we use Case we dont have any Manuals for this unit.
thanks
