How does the rear sonar system work on a Nissan?
System Basics The rear sonar sensors transmit a sensor signal to the sonar control unit (SCU) when detecting an obstacle at the rear of the vehicle. The system diagrams for Infiniti (left) and Nissan (right) vehicles look different in the ESM, but both vehicle types have four rear sensors.
How do I Turn Off the sonar system in my car?
In Infiniti models, drivers can cancel the sonar system’s alert by using the Rear Sonar System (RSS) OFF switch on the instrument panel. Also, the sonar sensor’s warning is played through the speaker system via the BOSE ® amplifier. In Nissan vehicles, the signal is heard through the sonar buzzer.
How do I know if my sonar system is working?
The sonar buzzer will sound once, and the Rear Sonar System OFF switch indicator will flash once. Although the sensors respond to slightly different measurements before they sound the buzzer, the work flow for their inspection and repair is the same.
How to stop sonar from sounding when you back up a Pathfinder?
If you have ever tried to back up with a trailer attached to your Pathfinder you will see that the sonar starts sounding immediately when you place the vehicle in reverse. By pressing the file button you can temporarily disable the sonar without having to go through the menus. Or back up with the constant beeping noise. Your choice.
How to tell if sonar is picking up something?
While the sonar is still beeping look at the information center and you will see a blinking indicator of which sensor is picking up something, back left, back center or back right.
How to stop a sonar from beeping?
When you get to the point where the sonar starts beeping press the brake and stop, leaving the vehicle in reverse. While the sonar is still beeping look at the information center and you will see a blinking indicator of which sensor is picking up something, back left, back center or back right. Now press the file button on the upper left of the steering wheel. The beeping will stop and the message in the center indicator will go away. At this point you can continue backing without the sonar being active.
Can you turn off sonar when backing?
In reality you *probably* would not do this while backing unless you are towing. When you are towing, the presence of the trailer behind the vehicle immediately causes the sonar to beep when the vehicle is placed in reverse. Nissan probably should have made the label clearer, like "To Turn Sonar Off" or "To Disable Sonar". Instead they went with the short-hand "Sonar Off"
Can you change the sensitivity of a sonar?
Through the steering wheel function you can also change the sensitivity of the sonar. I found when I had it set on the factory setting, you had to be almost on top of something for it to beep.
Does sonar turn off when turned off?
From reading the manual, the sonar always resets when the car is turned off and will return to the ON setting next time. Hitting the steering wheel button to turn it off is a one shot use and will not permanently turn the sonar off, just for that moment.
How does a rear sonar system work?
The SCU changes the output of the sonar display and the warning buzzer output frequency changes 4 levels (for center) and 3 levels (for corner) according to the detection distance condition. When the system is working correctly, it will beep slowly when the vehicle approaches an obstacle. As the vehicle gets closer to the obstacle, the beep will become faster. When the rear end of the vehicle is less than 10 in from the object, the beep becomes continuous. If the system detects a motionless object farther than 10 in from the side of the vehicle, the beep will sound for three seconds. The system aims to detect objects up to 6 ft from the bumper (detection range approximately 1.8 m (5.9 ft) maximum). The outer corners of the bumper have reduced coverage, and the system only detects objects that are stationary or moving slower than 3 MPH.
What to check for on a sonar sensor?

How to check ground circuit?
Check the ground circuit by examining continuity between the SCU harness connector and ground. If you discover a problem with the harness, repair or replace it, as necessary.
How to check if SCU connector is working?
Check the voltage between the S CU connector and the ground. If the results are normal, replace the sensor being tested. If the result is not normal, repair or replace the harness or connectors.
How to test sonar buzzer?
To test the sonar buzzer, repeat the same test procedures that were used for the sensors with the addition of a third test. Check the sonar buzzer signal circuit to the buzzer power. Turn the ignition OFF and check the continuity between the sonar control unit connector terminals.

The first test is to check the rear sonar sensor circuit continuity.
How many times does a sonar buzzer sound?

Rear sonar no sound when backing up, switch is lighting off
More than likely it needs a new beeper. When the beeper fails the light on the sonar button will stay illuminated and the system obviously won't make any sound.
