What Causes a Car's Reversing Radar to Stop Beeping?

[AnnieLynn]

If a car's reversing radar stops beeping, it may indicate a system malfunction that requires inspection. The troubleshooting methods are as follows: Check whether the wiring of the reversing radar at the rear bumper is properly connected; verify if the reversing light turns on when the gear is in reverse; remove the right-side lining of the trunk to test the continuity of the radar's wiring; open the fuse box and use a multimeter to check the continuity of the fuses related to the reversing radar; if the reversing radar module or buzzer is damaged, it needs to be replaced. The full name of the reversing radar is reversing collision avoidance radar, also known as a parking assistance device, mainly composed of ultrasonic sensors, a controller, and a display. When the gear lever is shifted into reverse, the reversing radar automatically starts working. When the radar detects that an obstacle behind the car is too close, the reversing radar buzzer or display device will issue a warning to remind the driver to pay attention to the distance behind.
