Why is one reversing radar not working?

[LaKiara]

The reason why one reversing radar is not working is that the circuit of the car's reversing radar has malfunctioned. The solution is to promptly go to the car's 4S store or a repair shop to inspect or replace the reversing radar circuit. The reversing radar, also known as the reverse collision avoidance radar or parking assist device, is a safety auxiliary device for parking or reversing a car. It consists of ultrasonic sensors, a controller, and a display. The reversing radar generally has four probes, installed at the rear or on both sides of the car, two on each side. When the gear lever is shifted into reverse, the reversing radar automatically starts working. When the probe detects an object behind, it emits a beep as a warning. As the vehicle continues to reverse, the frequency of the alarm sound gradually increases, eventually becoming a continuous beep.
