What to Do When the Reverse Radar Display Numbers Are Missing?
1 Answers
Reasons for missing numbers on the reverse radar screen: 1. Wiring issues: Check the connection points between the wiring and the vehicle installation for any loose connections, as poor contact can cause intermittent functionality. 2. Radar sensor malfunction: Inspect the reverse radar sensors, as faults can sometimes occur due to car washing or rinsing. 3. Radar hardware failure: The reverse radar itself may have inherent defects or damage, or there may be loose wiring. It is recommended to visit a professional repair shop for inspection. Below is how the reverse radar works: (1) The reverse radar is designed based on the principle that bats can fly at high speeds in the dark without colliding with any obstacles. (2) The reverse radar sensors are installed on the rear bumper, radiating at approximately a 45-degree angle to search for targets in all directions. (3) Its greatest advantage is the ability to detect obstacles below the bumper that are difficult for the driver to see from the rear window, such as flower beds or children playing behind the car, and to issue an alert. (4) When the gear lever is shifted into reverse, the reverse radar automatically activates. When the sensors detect an object behind the vehicle, the buzzer sounds a warning. As the vehicle continues to reverse, the frequency of the alarm sound gradually increases, eventually becoming a continuous tone.
