What to Do If One Reversing Radar is Broken?

[DerekAnn]

Since the four sensors of the reversing radar operate independently, if one is damaged, you only need to replace the faulty reversing radar. First, you can check whether the power cord of the radar host is properly connected and if there is current supply. Also, check if the radar host wire is loose. If both are fine, the issue might be a damaged buzzer. Below is a detailed introduction to the reversing radar: The reversing radar typically has four sensors, installed at the rear or both sides of the car, with two on each side. Also known as a reverse parking sensor or parking aid, the reversing radar is a safety assist device used when parking or reversing. It consists of ultrasonic sensors, a controller, and a display (or buzzer). The reversing radar system alerts the driver about surrounding obstacles through sound or a more intuitive display, making reversing and parking safer. When the gear lever is shifted into reverse, the reversing radar automatically activates. When a sensor detects an object behind the vehicle, it emits a beeping sound as a warning. As the vehicle continues to reverse, the frequency of the alarm sound gradually increases, eventually turning into a continuous tone.
