I can ask one of our guys at work who are product support engineers if they've got a moment to look at it. If the check engine isn't on, I wouldn't have known about it and am thinking it should be looked at, but it's not suggesting immediate action. I saw this code earlier in the week, and the check engine lamp did come on. However, after the 3rd restart, the lamp did not return and I've put some 450 miles on it since- and still no check engine lamp.
Thanks for the reply BTW...
