I believe on this year, it is part of the transmission range sensor. If you take a look below, I attached the entire wiring schematic for the backup lights.
Note: there is a relay as well that can be checked.
Confirm the fuse indicated is the one that was checked. Also, switch the relay for them as well.

Let me know what you find. Note that I had to cut the schematic in half to make it readable. I did overlap the pics so you can follow it.
