That code doesn't exist according to this site: http://www.dieselplace.com/forum/dtc.php

You can look up others there as they pop up.

It could be a software issue. I work on F-16s and they get fault codes too. Well, needless to say, we get codes that aren't listed too. If you don't continually get the same code, I wouldn't worry about it.
