What are the reasons for the reversing radar not beeping?

The reasons for the reversing radar not beeping are: a malfunction in the reversing radar circuit. The reasons for the reversing radar not working are: 1. Faulty buzzer or display; 2. Damaged reversing radar circuit; 3. Loose connection between the buzzer or display and the main unit. The solutions for the reversing radar not working are: 1. Replace the buzzer or display; 2. Inspect and reconnect the reversing radar circuit; 3. Tighten the connection between the buzzer or display and the main unit. The reversing radar consists of an ultrasonic sensor, controller, and display. Its working principle is that under the control of the controller, the sensor emits ultrasonic signals. When encountering an obstacle, it generates an echo signal. After the sensor receives the echo signal, the controller processes the data to determine the position of the obstacle. The display then shows the distance and issues a warning signal to achieve the purpose of safe parking.
Hey, I've encountered several customers complaining about their reversing radar going silent recently. The most common issues are: 1. The radar sensors are completely covered by mud splashes or heavy snow - a car wash and wipe usually brings them back to life. 2. Accidentally scraping the curb while reversing, causing the sensor to crack or the internal chip to malfunction. 3. Loose wiring connections in the trunk area, or plastic connectors cracked by sun exposure leading to water ingress and short circuits - particularly common during rainy seasons. 4. The dedicated small fuse for the reversing radar in the fuse box blowing - just replace it with an identical one. More serious cases involve the main control unit failing, which requires professional diagnostic equipment to test the circuits. For older manual transmission vehicles, also check if the reverse light switch is faulty - if it's not working, the radar won't activate either.
Last time when I was reversing my car, the parking radar suddenly stopped beeping, which really gave me a scare. First, I wiped each of the four small round sensors on the bumper with a wet wipe—no use. Then I checked the wiring connectors in the trunk, and they seemed secure. Finally, I consulted the manual and located the fuse box. After checking each fuse, I found that the 15A fuse labeled for the parking radar had blown. I bought a new fuse for two yuan at a nearby hardware store, replaced it, and the beeping sound immediately came back when I shifted into reverse! Later, I found out that it was because the technician didn’t properly wrap the wiring when modifying the reverse lights, causing the insulation to wear and short-circuit, which blew the fuse. This incident reminded me to always check the wiring protection after modifications.
