The rear sensors are activated whenever reverse gear is engaged; an audible signal will indicate the sensors are active. Detection of obstacles is signaled by a speaker. The frequency of the beeping indicates the detection zone within which the obstacle is detected. The faster the beeping, the closer the object.
The ECU has a built-in self-diagnosis system: if, when the control unit is turned on, the battery level is too low to guarantee the accuracy of the system, the speaker will almost immediately give out a deep warning tone for 5”. This will inform the user that ALL the sensors will be deactivated.
