'service Auto Ride ' Dash Message

[oddf192]

I have a 2001 GMC Yukon Xl (75,600 miles) Suddenly, I am getting a message says 'Service Auto Ride' Yet nothing seems out of wack. Truck sits level. I got under and checked all electrical connections. Checked to be sure nothing is visibly broke. Had Auto Zone do Diagnostic test,, read 'No Errors, Doesn,t seem to be affecting performance. I disconnected battery to see if message would go away,, no luck. I,m wanting to sell the truck only because I bought a newer one,, but folks ain't gonna' like that message. Any Suggestions ?? (Oh,, also, last summer when I took it in for inspection,, these clowns said that I needed a ball joint replaced,, I disagreed but had no choice,, wonder if they inadverantly dis-lodged some thing,, I don;t want to go back to those varmits,,, they will want to charge me another fortune !!)
