Don't you hate those intermittent problems that take forever to figure out. I got the service advance track message in April while at Charlotte Motor Speedway for the Mustang Owners Museum event. I disconnected the battery for a couple of minutes and it was gone when I reconnected. It was the only time I have seen this message. I hope it is the last, but if it comes on again, I will check the wiring harness.

Yeah and it's even worse when someone tells you what the problem is, and it still takes another year to finally get your butt under there and look!

I'd suggest you keep it in mind for the next time you have the car up on a lift, and remember it can happen on either side, and it's way up there hidden behind the exhaust pipe.

I know what you mean, each year it gets harder to slide under the car.
