DRIVING AIDS

DESCRIPTION AND OPERATION

86-2-3

Description

General
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 or manoeuvring in restricted space. It is 
not designed as a crash avoidance system or a replacement for visual interpretation for the driver.

The system comprises four ultrasonic sensors in the rear bumper, a control module, a fascia mounted control switch 
and a rear 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 deactivate the PDC system, if operation is not required.

PDC ECU
The PDC ECU is located in the rear right hand side of the luggage compartment, behind the side trim panel.

The PDC ECU uses a single microprocessor to perform the following tasks:

l

Control of the ultrasonic sensors

l

Monitoring of the sensors

l

Evaluation of received echo signals from the sensors

l

Noise and disturbance suppression

l

Control of the PDC sounder

l

Monitoring of the sounder and lead

l

Control and monitoring of the switch status LED and lead

l

Evaluation and monitoring of the control inputs

l

Management of diagnostic and test functions

l

Monitoring of power supply

l

Communication via diagnostic link.
