Is there a way to bypass the air compressor, like using 3-ohm resistors for the shocks?
Air compressor pump causing service suspension message

Pull the fuse for the air compressor, and then put a 5 Ohm 25 watt resistor across all 4 shock connector wires, if you want to completely disable the active suspension system and have no dash warning lights.
Alternately, replace the compressor, if you shock bladders are still intact (the main reason for compressor failures).

I should have been more clear. I already did the 3 ohm resistors at the shocks. I still need to get rid of the service suspension annoying message. The pump hasn't run in years.

Pull the compressor fuse.

that will cause the service message to stay on forever. I want to get rid of it.

Did you disconnect the SEO/ALC 10A and ESC/ALC 30A fuses? That provides power to the ALC and ESC module. Will have to disconnect battery afterwards.
(Lookin at '09 diagrams, no idea what year you have)
I have no idea if that will work, might depend if BCM is programmed to expect that option... (like obstacle detection was for earlier gmt900s, but not later ones)

I did not. My goal is the keep the front electronic struts working as designed. The rear shocks, however, keep ripping the air shocks, and the shocks go HARD.

Oh, I see.. So I take it you only did the resistors on the rear shocks.
Only other thing I have seen mentioned is fixing the (rear?) height sensors.. Disconnecting them from suspension and setting them to level position..

What code are you seeing? C0711 or C0712?
Since you said the compressor hasn't run for years, have you had this code for years also?
This page says the compressor will run on startup and check that pressure holds.
Might need to trick the compressor pressure sensor?
Maybe it won't run the compressor if it sees high enough pressure?
