Mitsubishi FB18TCB:
Code c21 -FET hydraulic .operation failure .Hydraulic Fet module error

How do l fix the above mentioned error code.
Background : the machine was invoved in a minor accident which damaged few cables to the main fet board( two cables shorted) , through visual inspection to the board was a damaged or burnt single transistor.The forklift showed codes c22( sensor current - current hyd) and b12(sensor current travel). From that point not a single operation was working except just showing those codes with the key on and other auxilliaries such as horn and lights.
I then repaired damaged wiring ,insulating naked parts it was a very small portion to replace whole loom.
I replaced damaged main fet board and the contactor.
After that all previous codes were cleared and l operated the lifting levèr ,then boom error code c21.
Is there anything else lm missing
