I would bet that your issue is not caused by a fuse. The fact that the "Rear Sonar OFF" lamp is on and won't turn off means that the system is in fail-safe. The system has sefl-diagnosis capabilities and has found a fault.
To enter the self-diagnosis, turn the key off. Depress and hold the rear sonar switch and while holding it in, turn the key on. You will see the lamp flash and may hear a beep from the warning chime. Release the button and push and release 5 times within 10 seconds. You should see the lamp flash and another beep. Push and release the button one time. This will display fault codes that are stored in the system. For example, if a code 12 is stored, you will see 1 flash, followed by a pause and followed by 2 flashes. If there aren't any other faults stored, this will repeat.
I have seen code 12 most frequently, being that the warning chime has failed. If this is the case with your vehicle, you won't hear the beeps that I mentioned earlier, but only see the flashing of the lamp.
If this is the case, you will need to replace the chime. It is located under the cover between the steering wheel and the windshield. There is a "hood" that faces toward the steering wheel and behind that is a cover that is held down with spring-metal clips. Get a small screwdriver or panel "popper" under this cover and gently pry it up. The chime is a small speaker directly under that cover and is bolted down with 2- 5.5 mm bolts.
Once you have repaired the fault, the system will automatically reset the self-diagnosis memory.
If you have other codes, you may have an issue with one or more of the sensors located in the rear bumper. I, however, do not know those code numbers off the top of my head.
I hope that you have found this helpful!

I have the same problem. I have a 2005 armada. I just went to Gillman Nissan in Rosenburg Texas today with the same thing, When you turn the vehicle off and turn it on again the problem goes away. I paid $241.00 to reset the VDC computer and I still have the problem. Also my backup camera just stopped working. This is my last Nissan auto. I am pissed!!

SOURCE: reverse sonar sensor - locked
check the small speaker that emits warning tone.if it is bad it will lock out operation as you describe and is by far the most common failure on thesesystems.usually are mouted behind instrument cluster.
