Just started getting this this week....any ideas where to start? Went to autozone to get them to run a code and nothing??

Tech

Take to dealer. I don't think autozone scanners can pull codes out of electronic brake control module or the electronic suspension control module. That message could mean lots of things. But there is an issue in the system and you should have a dealer check in to it.

Is it most likely related the compressor on the autoride system?

Tech

Yes that is typically what it is related to. The exhaust valves on the compressors go bad.

Hello, I'm getting the same message on my 08 Tahoe 4x4 with 49,700 miles. Is there anything else besides the compressor that may go bad to give you this message? It seems that when I hit a pothole I hear a bang coming from the right front, as if the shocks or something extend to their limit and I'm also getting a little sway in the front at higher speeds!

ie: fuses, relays etc

could also be bad air shocks. LTZ have air ride and the bags could be leaking. you should hear the compressor running a few seconds after you start the vehicle. if you don't hear it then more than likely it went bad. but it could be due to leaky air shocks. which would cause the compressor to constantly run and burn out. new shocks are a pretty penny but fairly easy to replace if you're handy.

Great, thanks. I'll have the shocks checked out as well as the compressor. The only thing I hear at start up is the fuel pump at this point. Have a good one!

Mine turned out to be a bad front shock...in fact it was broke..replaced and code went away
