OS 12606961

the reason i need to switch is that another person had a LQ4 in the truck that is no longer in the truck, so to put it back to a LM7 i am currently running a 2618 OS from a silverado.

the question is, does anyone know how to enable the air suspension in the 2618 OS or have a clean copy of the 12606961 OS?

thanks

edit -found out 9691 is the update OS for 2618, so ive grabbed an escalade os copy to attemp to get the autoride running
I don't believe the air ride is controlled by the PCM, but by the BCM, Body Control Module, at least it was in my old 2003 H2. I think you'll need a Tech2 to figure out what's keeping it from working.
