I have a copy of the service bulletin and posted it here somewhere. If you read the bulletin it appears to only do the check once you hit 2500rpm. I have made a game of it and go days without hitting the offending rpm. Does that mean the AdvanceTrac isn't doing it's self-check? Does that mean it won't engage?
It is still annoying that they can't fix it! It seems to me they don't care enough about an orphan car (or their owners, by extension) to put in the effort to fix it!! This, as well as their lack of acceptable product, will make me think twice about purchasing another Lincoln!
