2010 Service 4 wheel drive message

[totalpackage]

So the Service 4 wheel drive message came up for me on the way to work one morning. Its about a 18 mile trip there. It was clear on the way home that evening. So is that how it generally lets you know when to service it or is something wrong? I have not used 4x4 in about a month so have not tested it. If it needs just serviced, what do i need to do do it?

I believe it may not necessarily be the 4WD system, don't think it's a maintenance message either. Definitely hook up a code scanner to check.

Run it through its paces to see what's wrong since you don't have a proper scan tool to pull the codes.

You might also want to check that grounds to frame/body are making good contact.

I have a 2010 Tahoe LTZ 150K miles with the same service light concern. It came on when I switched the control from Auto to 2WD. Switching back didn't seem to help. I haven't had any noise/grinding; as far as I know, all is working. If I might ask, what did you find out, and how was it resolved? Thanks!!
