Has anyone ever tried to do a full reset by disconnecting the battery and letting it sit?

I would think, in the event of a battery being disconnected, tieing the battery cables together and letting the vehicle sit for a few hours, then reconnecting the battery should start
a 'factory' reload of all the moduels to the BCM?

I am still trying to track down an errant setting that is causing the PROXI align to fail.

The PROXI is looking for a module that doesn't exist, and then fails when it doesn't find it.
