GF54.65-P-4102-03A Sensors, Function
- with CODE (220a) Parktronic System (PTS)

The sensor actuated by the Parktronic control unit (N62) transmits an ultrasonic signal and is ready to receive after a brief delay (time for the diaphragm movement to decay).

Each sensor receives the echoes of its own ultrasound signals and the echoes of ultrasound signals from adjacent sensors. The distance to the obstacle is calculated from the journey time of the echoes.
Detection angle:
horizontal: 120 degrees
vertical: 60 degrees

There are several versions of the sensors depending on vehicle model/model year. Different versions of sensors must not be installed together. Faulty seat or mechanical damage to the sensors or the wrong version of a sensor, can cause malfunctions or incorrect displays.
