PDC Sounder
The PDC sounder produces the audible warnings with which the PDC ECU informs the driver of system status and 
objects detected at the rear of the vehicle. The PDC sounder is installed behind the trim in the RH side of the luggage 
compartment, on the underside of the shelf.

The chime produced on the PDC sounder has a lower tone than that produced on the instrument pack sounder (which 
is used to warn of objects detected at the front of the vehicle), to enable the driver to differentiate between the two.

Parking Switch
The parking switch is a non latching push switch installed on the centre console for selecting the system on and off. 
When pressed, the switch connects a ground to the PDC ECU. An orange LED above the switch indicates when the 
PDC system is active. The LED is activated by a power feed from the PDC ECU.

Pin No.
