Diagnosis and Testing
Tests Using the Portable Diagnostic Unit
Refer to PDU User Guide
The complexity of the electronics involved with the speedomete r and instrument cluster, of which the Message Center is a
part, and the two multiplexed communication networks which ar e connected to it preclude the use of workshop general
electrical test equipment. Therefore, refe rence should be made to the PDU User Guide for detailed instructions on testing
the speedometer and odometer.
The PDU systematically te sts and analyses all functions and the various systems affected by it.
Where a fault is indicated, before replac ing a component, some basic diagnostic methods may be necessary to confirm that
connections are good and that wiring is not damaged.

Parking Aid - Parking Aid
Description and Operation
Page 1869 of 2490

The functi
on of the parking aid is to prov
ide an audible warning to the driver of the distance to obstacles near the rear
bumper of the vehicle when parking or travelling at a slow sp eed. The system provides an assistance to the driver when
parking in order to help avoid collision with obstacles.
The sensor range at the rear of the vehicl e should be 1.8 meters. This should extend the full width of the rear bumper and
reduce to 50 cm at the vehicle co rners. The vertical range is adequate to protec t the highest and lowest points of the rear of
the vehicle. The system will detect curbs with heights of at least 18 cm. Obstacles, such as curbs, that are low enough to
pass under the vehicle until they make contact with the tires will not be detected.
The system activates a specific speaker with a tone signifying the distance to the obstacle. The tone consists of a beep and
defined space ratio which varies depending on the calculated distance. When the distance to the obstacle is less than 20 cm
the speaker tone is continuous.
The parking aid is continuously in operation, unless towing wh en the system automatically switches off. If the reverse aid
develops a fault the tone will sound continuously for three seconds when the igni tion is switched on or the reverse gear is
selected.
The parking aid system comprises of:
a
module mounted in the batte
ry junction box (BJB).
fou
r rear bumper mounted sensors which have a 90° angled electrical connector.
an audible speaker, moun
ted on
the rear parcel shelf.
