Why does the reverse radar keep beeping as soon as it enters R gear?

[JosephDella]

Reverse radar keeps beeping as soon as it enters R gear because it is too close to an obstacle behind the vehicle, at which point the buzzer will start sounding to alert the driver to the distance from the obstacle. Other reasons that may cause the vehicle's radar buzzer to keep beeping: 1. Signal blockage: Something is stuck on the reverse radar probe, causing signal blockage. Solution: Check if there is anything blocking the radar holes at the rear of the vehicle. 2. Water leakage: The rear wiper hose is leaking or water has seeped into the reverse radar system. Solution: Seal the leak (or replace the hose) and drain any accumulated water from the radar system. 3. Signal error: The radar's 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. 4. Radar malfunction: The reverse 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.
