Problem with SSK2 in Speed master 52

I have a problem with the SSK2 in a Heidelberg SM 52-4? Someone can help me

 

You'll have to post more information. Screen shot of display would help, or thorough explanation of problem listing diagnostic codes.

 

Thank you junker.
The problem start with a problem with the movement of the side lays and pression motors, so the technician think that the problem was in the board SSK2.But before change this board, he reset the SAK2 and when he restart the machine, after put the values of the machine, the machine ask to change from reverse to front, but when you told the machine to do it, the machine seems that is do it the change in the panel but the machine doesn´t do any movement
