Why is the Honda Civic's reversing radar not beeping?

[VivienneLee]

If the radar is not beeping, first check whether the power cable of the radar host is properly connected and whether there is current supply; then check whether the radar host cable is loose. If neither of these is the problem, then the issue may lie with the radar itself. More details are as follows: 1. The reversing radar is a safety auxiliary device when parking or reversing the car. It can inform the driver of the surrounding obstacles through sound or more intuitive displays, eliminating the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle, and helping the driver overcome blind spots and blurred vision. 2. If the problem is confirmed to be with the reversing radar, the first possibility to consider is a faulty buzzer. In this case, you need to purchase and install a new buzzer. 3. Also, recall whether any modifications have been made recently. If so, it is possible that the reversing radar's wiring was damaged during the modification process. In this case, the car should be taken to the original workshop or a 4S shop for inspection. 4. After prolonged use, the reversing radar may develop faults, such as the inability to emit warning sounds.
