Self Leveling Suspension Module

[rody1285]

I have been having a problem with my air suspension.

On occasion I would get the self level suspension inactivate error so I used my INPA software to clear it and the suspension would rise to a useable height. I was never able to successfully resolve the air ride issues. Over the past 3 years I have replaced all the air bags, and air compressor, but still got the codes.

Now I have a new problem, INPA does not find the module so I can't clear the codes or active the front to rise.

I get a message "No Response From Control Unit"

Is control module bad? Literally disappeared one day, I also checked on another scanner and it was gone.

I checked all the fuses (glove box and rear right panel) and also checked the high voltage fuses (near spare tire on back to the left )all were good.

I ordered another module 'used on ebay' and the module was still not found??? Luckily I was able to send it back, I guess its possible that both modules were bad but that doesn't seem likley.

Has anyone every lost a module? Is there an issue with the module getting power?
