Light issues
I have a 2013 Cummins and I had taken to the dealership for recalls recently and had my oem trailer brake system activated, and figure out why my truck outer cab lights don't turn on along with my mirrors lights. They had did the scan it says my door modules are causing the issue apparently just curious. Also they did activate the trailer brake unit but it didn't engage with my trailer far as adjust the brake.
