What is the reason why the XuanYi reversing radar does not sound?

The reason why the reversing radar does not sound is that the power cord is detached, the buzzer is faulty, or the wiring at the bumper is not properly connected. Power cord detachment: First, you need to check whether the power supply of the main unit is properly connected and whether there is current. Then, check whether the radar main unit wiring is loose, and whether the reversing radar wiring is aged or broken. If the reversing radar cannot work normally due to the above situations, it needs to be replaced at a repair shop. Buzzer failure or improper wiring at the bumper: If the reversing radar buzzer is faulty or the wiring at the bumper is not properly connected, you need to go to an auto repair shop for inspection and replace it if necessary. Working principle of the reversing radar: The principle of animal bionics is to inform the driver of the surrounding obstacles through sound or more intuitive display, eliminating the troubles caused by the driver's need to look around when parking, reversing, and starting the vehicle, and helping the driver to eliminate blind spots and blurred vision defects, thereby improving driving safety.
I previously encountered a situation where the reversing radar on my Nissan Sylphy failed. I think the most likely reason is that the radar sensor was covered by dirt or debris. The radar sensor is an ultrasonic device hidden in the rear bumper. If it's covered with mud, snow, or dead insects, it can't emit signals. You should first park the car safely and carefully clean the sensor surface with a damp cloth. Another common issue is a loose wiring connection, possibly caused by bumps that dislodged the connector. Check if the wiring harness around the sensor is securely plugged in. If the radar still doesn't work after cleaning, the fuse might have blown. Locate the fuse box under the dashboard, refer to the manual to find the fuse for the reversing radar, and replace it with a new one. Occasionally, a faulty control module could also cause this, but it's less likely. Remember to address the issue promptly to avoid accidents while reversing.
