Yes if you have a Bi-directional Isolator Delay Relay (BIRD) and it's associated Trombetta and battery disconnect relays. There was an extensive 100+ posts here on the forum. Go to search and put in BIRD and it should take you to the discussion. In the discussion are pictures of the BIRD. When you see what it looks like, look under your hood for it. Being a 2015, I'd be real surprised if you did not have one.

My 2015 37ND does. I verified that with a multi meter a couple of weeks ago.
The BIRD on my coach is in the battery bay. I had to remove one mounting screw and spin it so I could verify the part number but it is there.
If you look on the upper right in the photo you will see a red square. The black box behind that square is the BIRD. I also attached the BIRD documentation in PDF format rather than the jpeg images floating around.
