2017 Yukon Denali "Service Leveling System" troubleshooting

[B33tl3]

I have a 2017 Yukon Denali with Magnatic ride Z95 that shows "Service Leveling System" every time we crank it. 

I tried pulling codes but there are no codes. Any idea how to troubleshoot this?

 

Next step is to check connectors on the shocks but other than that I am at a loss. Don't want to take it to the dealer.

You need a better code reader. One that can pull codes from the individual modules.

Any suggestions for one? I am using a generic bluetooth ODBII module and an app.

I use this one, with much success, but is quite a bit more expensive than most folks want to spend:

I’m not advocating for this one, but it may do the trick. And with the current sale ($107), at a quarter of the price. But recommend checking (send them a message) with the manufacturer/seller just to be sure it’ll retrieve the suspension codes, which I think are stored in the BCM:
