The DC I am referring to is the Display Commander ... this is the ASA In Command technical term for the LCD display for example when downloading new firmware for it vs. the BCM which is Body Control Module which is the relay panel for the In Command and has its own firmware.
Just power off the In Command LCD panel before turning off your 12V disconnect switch and the annoying priming should not happen.
Work directly with ASA ... Keystone and dealerships (unless find one of the few good techs) is useless:
