Why does the car radar keep beeping?

[VanRyan]

Here is the relevant introduction about why the reversing radar keeps beeping: The reversing radar probe is stuck with something, causing signal blockage; Solution: Check if there is anything blocking the radar holes at the rear of the vehicle. The rear wiper water pipe is leaking or water has seeped into the reversing radar system; Solution: Seal the leak (or replace the pipe), then drain the accumulated water from the radar system. The radar ultrasonic signal is faulty, causing false alarms; Solution: Restart the engine, drive the vehicle to an open area and try reversing again to observe the effect. The reversing radar circuit is short-circuited or the radar module is faulty; Solution: Take the vehicle to a 4S shop or repair shop for inspection, check the circuit or replace the radar module.
