I honestly have no idea. This is a follow up to the self-leveling sensor issue that I posted about a week or so ago.

I replaced the following: Air Suspension Control Module, AHM Trailer Recognition Module and am trying to find where the relay fuse goes.

After replacing the two modules, the self leveling still does not work and gives me the same error code on the dash. I'm not sure what the relay has to do with the self leveling and am starting to seriously question their diagnosis.
