Lifting and Control Valve Problem (include error codes)

Dear All,
I have Toyota 7FD30 and i have serious problem with my lifting and control valve, when i lift the mast, after a period of time it will go down slowly by itself, it's like the control valve can't hold the mast for long. I have checked all the seals and hose and it's dry no leaking all, i have replaced sealkit set (o-rings)in the control valve and it's not leaking and i have cheked the piston in control valve and it's in a good condition.
It really confusing, can anyone help? Thank you all.

And i have the error codes: 54,61,62,67,71. I have read the information for err codes 54,61,67 from this forum. For err codes: 62 and 71 anyone have clues? Thanks..

Hi, error code 71 will normally have another number after it say 71-1 or 71-2, you need to be looking at your tire angle sensor and wiring to it, its located on the right rear stub axle, it sits on top of the king pin. Error code 62 should also normally have a second number but start looking at the tilt angle sensor and wiring, thats located on the right tilt ram. Tbh looking at you other codes lift height code, load sensors codes and lift lock codes, you seem to have a lot of different sas codes at once. I would start and check out the wiring on the truck for the sas system, make sure good power supplies and earthing points, connection into the sas controller etc etc.
