Why is the Civic radar not alarming?

[ElenaAnn]

Civic radar not alarming requires first checking whether the power cord of the radar host is properly connected and whether there is current supply; then check if the radar host cable has become loose. If neither of these is the problem, then the issue may be a damaged buzzer. The reverse radar mainly consists of ultrasonic sensors, a controller, and a display or buzzer. Here is their introduction: 1. Ultrasonic sensor: Its main function is to send and receive ultrasonic signals, then input the signals into the host, which are displayed through the display device. 2. Controller: Processes the signals and calculates the distance and orientation between the vehicle body and the obstacle. 3. Display or buzzer: When the sensor detects that the distance between the car and the obstacle reaches a dangerous distance, the system will issue an alarm through the display and buzzer to alert the driver.
