I never had it come on but the first thing I would check is your oil % on the computer (if it was not reset at last oil change or you need to change your oil now?). Perhaps it is some regular scheduled maintainance. Check your owners manual to make sure.

It's definitely not the oil %. I looked in the manual and it said take it to the dealer for an electrical check. That's the last thing I want to do though!

I had the Service Engine Soon message in the DIC a couple of weeks ago. Just after the belt tensioner folded up and the alternator stopped spinning. Funny thing - replacing the tensioner and belt took care of it. Figured I'd do the A/C belt, too, since I was there.
Codes will tell. Based on my problem, check for charging, too. If your voltage is low, or picks up slow, you may have an alt problem.
I'd also suggest looking at the belt tensioner once in a while. Mine didn't fall apart - it just started listing toward the nose of the car, and threw the belt. Looked fine with the belt off. Put the belt back on and looked, and it was probably close to a quarter inch out at the top of its pulley. Never thought to look at it before. Easy fix, not too expensive. Didn't even cost too much knuckle hide.

Sounds like a good correlation. May be low output. Bill Curlee has a great bunch of posts on chassis grounds, too. Probably worth looking at those, as so much of this car relies on those grounds. They are subject to corrosion, and Bill's write-up covers the locations and corrections. The two in front are on top of the frame rails, just behind the headlights. I need to look at mine - I get a few electrical gremlins.
But man, that belt going bye-bye was something. Took less than three blocks for the temp to start coming up sharply.
Belt could be at fault in your case, too. Check the marks on the tensioner to see that the belt is still tight enough. There are three, if memory serves. The pointer on the movable part should between the two closest to the throttle body. Farther it is toward the outside, weaker the belt tension is. Belt is cheaper than an alternator. Good luck.
