We had a great time tonight, took the tops off and went cruising, lots of rubbernecks looking at us, and people quickly pulling out cameras.

We did have a new bug though, got a Service Height System message, and now no control of heigh adjustment. @Nebula1701 any ideas how to reset that without a trip to the dealer?

probably something triggered a trouble code and disabled it.

A few options: a power cycle, unplug the 12V, get an OBD2 reader and clear the codes.

Otherwise maybe one of the position sensors went bad, has a lose connection, or a fuse popped.

Did you have the new height sensors installed yet?

I had them installed last week, this thing is crazy looking in extract mode! Def makes me feel like I should have bigger wheels/tires on this thing! Too bad you can only go 12 miles an hour in extract mode (not really surprising).

How do you enable extract mode? Is it now a physical switch or in the UI?

There is a DTC, but my reader cannot access it.

Amazon is awesome, ordered the OBD2, and it just arrived... Only a couple hours... amazing.
Whats the warehouse right next door to your house?? 🤣. Damn that would be the quickest forum turn around ever, OBD reader, posted, ordered, delivered all within hours. Now tom, just let us know if it has the hummer in it and if it works. Well done boys!

Has the OVA Over the Air update been released yet?? Can the dealer update it ?
Per GM you need to go to a dealership so they can install the new required height position sensors and install the update.
I think trucks produced recently and after the shut down is over will not need either.
