The Denali that I bought has that message on startup. The truck was wrecked on the front passenger side, so I'm gonna assume it's something up there.

What would make this code come in? I haven't been under it yet to look at it, but will some time this week.

Sounds like the harness that goes to the electronically controlled shock absorber is chaffed or broken. Inspect around that area for anything that looks damaged or disconnected.
