What Are the Reasons for the Parking Sensor Not Working?
2 Answers
The reasons for the parking sensor not working are: 1. Buzzer or display malfunction; 2. Parking sensor circuit damage; 3. Loose connection between the buzzer/display and the main unit. The solutions for a non-working parking sensor are: 1. Replace the buzzer or display; 2. Inspect and reconnect the parking sensor circuit; 3. Tighten the connection between the buzzer/display and the main unit. A parking sensor consists of an ultrasonic sensor, controller, and display. Its working principle involves the sensor emitting ultrasonic signals under the controller's command. When encountering an obstacle, an echo signal is generated. After the sensor receives the echo signal, the controller processes the data to determine the obstacle's location, displaying the distance on the display and issuing a warning signal to achieve safe parking.
I've been driving for twenty years, and the reversing radar has malfunctioned several times. The most common reason is the probe being covered with dirt, which can easily get clogged if the car isn't washed properly; aging or loose wiring, check if the plugs are secure; a blown fuse, try locating the relevant position in the fuse box; a faulty control module, which may need replacement; sometimes it's accidentally turned off in the settings, check the dashboard for any switch prompts. Environmental factors also play a significant role, as probes can fail when dampened by rain or snow, just keep them dry during cleaning. Maintenance advice: clean the sensor surface monthly, test its response before driving, and ensure safe reversing without negligence.
