I just had same error code. I have had the wii u since it was released. No problem until today. I am on a wireless network and the I had a pro controller plugged into usb to charge but was using the wii u game pad. All updates both game and system had been run previous to today so are were up to date and non were done today. The only odd thing it did before the crash was not connect to wireless. I was starting a game of nba2k13 and it said online was not available and the mycareer was not available. Then a short time later the code popped up. Any guesses as to what causes this error code. I googled and went on nintendos site but haven't had much luck.
