Hello all- I just picked up a slightly used 2015 Altima. I was installing a trailer hitch yesterday and had the trunk open for awhile. I changed the trunk light bulb out to a LED. After a couple hours I heard a click and the trunk light shut off. I tried closing and reopening the trunk, along with putting the halogen bulb back in, but it still won't turn on. All interior lights work so it's not a fuse. Even after driving to work today it still won't come on, but the car does show the trunk is open on the dash when I open it.

What can I do to fix this?

Either a fuse blew or the LED is bad -- a quick and easy check would be to reinstall the OEM bulb and see if it works.

It looks like it fixed itself. This car must have some sort of automatic light shutoff after a certain period of time. The bulb was also loose, and must have come loose when I shut the trunk. Re-seating the bulb did the trick.

Review INL-57

That tells you that the bulb is supplied power at all times and the BCM is responsible for grounding the other side of the bulb to illuminate it. Use a meter, do you see 12V on one of the bulb contacts? If yes, it's wiring and/or the BCM.

There aer consult tests spec'd in the above link. But I think in other parts of the FSM you can get the BCM section and do some kind of pedal dance to put the BCM into test mode. That would allow you to force the BCM to illuminate the trunk bulb, if it can.
