mast in lock out mode

Hello, I have a Yale unit GTP 050 MX and the mast is in lock out mode. I replaced the seat switch, checked all the fuses and swapped the relays and nothing. I pulled codes 005 and 007 from the dash. I don't have a scanner. Does anyone have any suggestions?

Don't know that model well but L would look at the hyd control valve there must be a lock solenoid on the spool that is bad causing it to not unlock.
