    The BCM controls that function as stated, currently there is no way to fix or override the BCM module as HPT doesnt have access to it. the GMTIS system will only flash the current firmware for any particular module based on the VIN that is store in that module. You can substitute or use a VIN from another vehicle anymore, all of the modules in the car are VIN tied now.
