Hi, If using a new main board yes you will have to program it. The new boards come without data. if you happen to obtain a used one then the focus and shutter speed will have to be set still. If you don't have access to software to change it then the only solution to set the focus would be to see where the focus is at and then adjust the ccd screws in small turns until you can set the focus. You would have to keep taking the main board off and adjust the screws until focus is correct. I have software to adjust but when I didn't I used a Canon 50 1.4 lens and a focus chart that you can easily get online. I would mark the screw and the metal next to it to know how much i'm adjusting. If the unit is back focusing then I would back out the screw in small turns about half a turn depending on how far it's off. i would repeat this process until focus is correct. The main boards on Canon cameras need data like focus, white balance, shutter speed and so on to be set when replacing. Very rarely when I use a used...

When I see this error code this is usually the case for me and an easy fix. You will have to take off the back cover and there is a flex for the card reader that is connected to the main board on the lower right of the board. You would have to remove the flex from the board and use a light source to look at the bottom board to see if the screw is missing. I usually find the screw by tape around the view finder area when the back cover is off. I also find it when taking the front cover off and it will be stuck to the shutter motor. Usually after finding that screw it cures the error and the camera will work as should. To take off the back cover there is four screws on the back around the viewfinder, three on the bottom and one under the grip on the back cover. Be careful when removing the back cover as there is a flex connecting the back cover to the main board.
