Inputs and Outputs
Three connectors on vehicles with front and rear sensors
and two connectors on vehicles with rear sensors only
provide the interface between the parking aid module
and the external parking aid components.
The module receives inputs from the following:
•Reverse selected - CAN message from transmission
control module (automatic transmission) or transfer
box control module (manual transmission)
•Forward gear selected (not in reverse or neutral) -
CAN message from transmission control...

within the parking aid module constantly monitors the
system and alerts the driver to a system fault by emitting
a tone from the front or rear sounder, depending on the
fault.
If a parking aid system fault has occurred, the parking
aid module will relay the occurrence of the fault to the
driver in the following ways:
•The status LED will flash at a frequency of 2Hz if
the system is active and fault is detected in the
sensors, sounders, related wiring or the module.
•The front sounder will emit an error...

PARKING AID SWITCH
Switch1LED2
The parking aid switch is located in the centre console,
above the integrated head unit, to the left of the hazard
warning flasher switch. The switch is a non-latching
switch with an integral LED. The switch receives a 12V
output to drive the LED when required. The switch is
also connected to ground. When the switch is operated,
the momentary completion of the ground is interpreted
by the parking aid module as a signal to enable or
disable the parking aid system.

PARKING AID SOUNDER
The parking aid sounder is controlled by the parking
aid module and emits a series of tones of varying
frequency to inform the driver of the distance between
the vehicle and a detected object.
The rear parking aid sounder is located in the LH side
of the luggage compartment, behind the side trim panel,
below the window. The sounder is secured with two,
self tapping screws into the body. The sounder is
connected to the parking aid module via a harness
connector.
The front parking aid...

The parking aid module receives a signal on the CAN
from the central junction box when a trailer is fitted.
When this signal is detected, the parking aid module
suspends operation of the rear parking aid sensors.
On vehicles with front and rear systems, the front system
is activated when the ignition switch is in position II,
the vehicle is out of Park and the Electric Park Brake
(EPB) is off. If the vehicle speed subsequently goes
above approximately 10 mph (16 km/h), the front system
will switch off....

Intermittent Warning ToneAContinuous Warning ToneB
Detection Calculation
When operating in the combined transmitter and receiver
mode, the sensor outputs a number ultrasonic pulses
and receives the reflected echo signal. The parking aid
module amplifies the received echo signals and
compares them with a preprogrammed threshold to
calculate the distance to the object. This is achieved by
determining the elapsed time between the transmission
and reception of the ultrasonic signal.
When...

stored in the module memory. From the received
distance from each sensor and using the known distance
between adjacent sensors, the module can calculate the
minimum distance from the vehicle to the object.
When approaching several objects, the module
recognises the distance from the vehicle to the nearest
object.
