Anyone have this code pop up on the DIC? I know its cold as hell here in WI, might that have anything to do with this? I've got an extended warranty, just want to do a little homework first... 07 Yukon slt2 4wd 91,*** all stock suspension.

This can be triggered by many things--you need to have the code read from a Tech II or higher level scanner to see what is triggering that warning. It usually comes from the autoride pump not running. Start your truck and listen to see if the pump kicks in. I personally have replaced the my rear air shocks once and the compressor twice. Lots of info on this subject-just gotta do some reading 
And its not cold as hell-its cold as f*#k lately-tomorrow morning gonna be -18 with wind chills around -40 brrrrrrrrrrrrrrrrrrr

funny thing is i am in the middle of replacing all my suspension and air pump - including the rear drivers level sensor - and i never got a message across the dash.
been driving with no air in rear shocks & a bad drivers rear level sensor for 2 weeks - and the dealer says they can't turn on the air pump due to a problem in the wire harness. still no warning message after I replaced all shocks and air pump unit. i have no clue why, and the dealer is saying they want $1,500 to replace the harness.
So, i hope you have a better experience than me. I would have never bought this yukon if i knew i would have had to spend $1.3k in suspension and $1.5k in a wire harness.
Worst part is there was no way for me to know - because there was no message on the dash when i test drove it.
