Operating principle
Depending on equipment, the vehicle may be equipped with ultrasonic sensors integrated into the rear bumper.
Built-in ultrasonic sensors in the rear bumper of the car «measure» the distance between the vehicle and the obstacle when reversing. The measurement is accompanied by sound signals, the frequency of which increases as the vehicle approaches the obstacle; as soon as the distance between the car and the obstacle approaches 40 centimeters, the signal will sound continuously.
An audible signal sounds when reversing. If the beep is continuous (3 seconds), it indicates a malfunction.
Note: Make sure that the ultrasonic sensors are not covered (mud, snow, etc.).
