I don't know. Don't have that module in my truck as she has the dumb suspension (ZW7). We'll have to wait for Mike and Wes to tell us what their Tech2s say. Unless your Denali has it?

That's what I was saying. I've replaced all the components in The Beast with no need for a calibration.

Does The Beast still have that set up? If so, what does the Tech2 procedure actually do? Screenshots?

I also have the Z55 suspension, several weeks ago I replaced all shocks the fronts with oem parts and the rears with Arnott (Arnotts have a life time warranty lol) and I did not do any programing, the message error went away by it self. I did notice my ride height on the rear raise up about 1/2" not enought to worry about it.
It does. I'll give it a try today with the Tech 2.
I don't have a tech2 but I also have replaced all the shocks and the pump and it has driven just fine with no issues.
here is the link to what I referenced above, I was just chiming in after the op reported that dealer said it had to be recalibrated, which I had never heard of before.

your right, I am considering getting one here sometime sooner or later will probably come in handyNot yet!
I remember back when I was trying to figure out why my service suspension light kept coming on, I read about the trimset and bumpstop calibration but nowhere could I find what exactly it did. The error turned out to be the spoofing resistors on my Arnott Shocks which I fixed by wiring some resistors in. Today, since I have a Tech 2, I figured I’d give it a try. And after I did it, I still have no idea what it did. The Tech 2 just says it takes about a minute and then it says it’s done. I tried a different procedure, recalibration, under the suspension menu, but it said I needed to use SPS and I can’t find the SPS menu. I was able to test everything like the compressor, exhaust solenoid, etc. and everything works but I already knew that. If I have any future problems the Tech 2 will sure help me troubleshoot.

SPS in on the main menu, right under diagnostics. But that is programming from either TIS2000 or TIS2Web. Speaking of the former, I'm still working on it. We had another laptop but it was not set up properly so I'm doing that now and when done will try that copy on it. As for the programming, unless one has TIS2000 or already has a subscription to TIS2Web, I wouldn't bother. Well, maybe, it would be there in the back of my stupid mind, wondering just what it could possibly be that needs doing that everyone gets away with not doing!!! LOL
