DRIVING AIDS
86-8-4 DESCRIPTION AND OPERATION
Description
General
Park Distance Control (PDC) is introduced on vehicles from 03 model year. PDC provides an audible warning to the
driver when any obstacles are in the path of the vehicle during a reversing manoeuvre. The purpose of the system is
to assist the driver when parking and is not designed as a crash avoidance system or a replacement for visual
interpretation by the driver.
The system comprises four ultrasonic sensors in the rear bumper, an ECU, a fascia mounted momentary switch and
a sounder unit. The system operates using ultrasonic signals which are transmitted by the sensors. The reflected echo
from this output is received by the sensors and used by the PDC ECU to calculate the distance from an object.
The fascia mounted switch allows the driver to de-activate the PDC system if operation is not required or the vehicle
has a trailer attached.

The PDC ECU is located in the LH side of the luggage compartment. A bracket is attached to the 'E' post, behind the
trim panel and provides for the attachment of the ECU and the PDC sounder.
