1. GENERAL DESCRI PTI O N
Reverse Parking Aid (RPA) is an electronic system designed to provide an acoustic tone informing the driver of
obstacles at or near the rear of the vehicle during reversing maneuvers. Available only on Sedan and Coupe
models, the RPA primarily consists of four ultrasonic rear object sensor assemblies mounted to the rear bumper
fascia and an electronic control module assembly which incorporates an alarm assembly.
The RPA does not relieve the driver of duty of care when reversing the vehicle. Caution must always be
exercised.
Sonar is used to detect the presence of obstacles within a defined area, by measuring the time between the
transmission and reception (echo) of sound waves.
When reverse gear is selec ted, the sens ors sequentially transm it shor t ultrasonic pulses and then listen for an ec ho
reflected from an object within range. The electronic control module uses echo data from one or more sensors to
calculate the distance to the obstacle.
An audible intermittent tone is sounded through the alarm informing the driver that an obstacle has been detected
within the range of the system. As the distance to the obstacle draws closer, the frequency of the tone increases
until it becomes constant at a distance of approximately 30 cm or, 45 cm for vehicles fitted with a towbar.
NOTE: Some sound absorbing or reflecting materials can effect the range of detection. In extreme cases,
temporary non-detection of obstacles can result.
While operational, the control module constantly monitors the system for faults. Should a fault occur, an audible
warning is indicated to the driver. A diagnosis system aids the technician locate the source of the fault.
On vehicles produced after the start of W K production, connector X907 has been changed from a male connector
to a female connector on the trailer harness to eliminate the use of a short patch harness.
1.1 OPERATION
COMPONENTS
Rear Object Sensor Control Module Assembly
The rear object sensor control module (1) and alarm (2) are the one assembly. For Sedan models it is mounted to
the rear window panel, refer to Figure 12F-1.
Figure 12F-1
For the Coupe, the rear object sensor control module assembly (1) is mounted to the right-hand rear radio speaker
bracket, refer to Figure 12F-2.
Figure 12F-2
The ro le of the contr ol m odule is to trigger ultrasonic pulses s equentially from each sens or and m onitor the sens ors
for any received pulses (echoes from an object). The signals are then filtered and the distance of the object is
calculated from the time elapsed between the transmission of the signal and its reception using triangulation data
from one or more sensors. The control module also has a self-diagnosis function and controls the output tones
through the alarm.
Other peripheral functions of the control module include protective circuits against over-voltage, voltage stabilisation
and voltage supply to the sensors.
Rear Object Sensor Assembly
Each of the four rear object sensor assemblies (1) are mounted in a rear object sensor housing (2) which is heat-
staked to the rear bumper fascia. The housings allow easy removal of the sensor and rear object sensor ring (3),
refer to Figure 12F-3. Sedan shown, Coupe is similar.
Figure 12F-3
If the rear bumper fascia assem bly is replaced, undam aged housings can be rem oved from the old bumper fascia
by c utting the four attac hing heat-stak es . The hous ing can then be heat-s taked onto the new fasc ia with a soldering
iron, refer to Section 1D BUMPER BARS. If the housings are damaged, replacement parts are available. New
housings are to be painted to match the bumper fascia using similar methods to painting the fascia, also refer to
Section 1D BUMPER BARS.
Each sensor operates as a transmitter and receiver of ultrasonic pulses and the exposed surface painted in the
vehicle’s body colour.
IMPORTANT: Replacement sensor assemblies are supplied pre-painted in the vehicle’s body colour. DO NOT
apply further paint to the sensor as it will have a detrimental effect on the sensor’s operation.
The rear object sensor ring is made from silicone and prevents vibrations from the sensor being transferred to the
surrounding components. Without the sensor ring a change to the sensor characteristics would result.
Wiring Harness Assembly
The body wiring harness is routed (1), refer to Figure 12F-4 for Sedan or 12F-5 for Coupe.
The rear obj ect sens or harness (2) connects to the body wiring harness with connector X905 (3) near the left-hand
tail lamp assembly and is routed across the inner side of the rear bumper fascia, connecting each of the four
sensors.
The white wiring connector X906 (4) is provided to enable modification of the detection area for the fitment of a
towbar tongue.
When fitted, a circuit from the trailer harness is connected to the black wiring connector X907 (5) and is used to
detect tr ailer attac hment. When a trailer , c aravan, bike car r ier with lights, etc. is c onnec ted to the trailer harnes s the
system is then temporarily disabled, refer to TOWING for further information.
The diagnostic connector X156 (6) is located on the left-hand side of the rear compartment. Refer to
3. DIAGNOSIS for further information..

DETECTION & WARNING
The four sensors are mounted onto the rear bumper
fasc ia in an arrangement that pr ovides a slight overlap
of the polar patterns. This provides the best coverage
of the detection area.
The maximum detection distance is set to 150 cm by
the control module software.
When the ignition is on and revers e gear is s elected, a
ready tone will sound from the alar m f or a per iod of 0.5
seconds.
The control module provides a voltage to each sensor
sequentially which is converted into an ultrasonic
pulse.
Where an object is within the detection range, the
ultrasonic pulse is reflected (echoed) and received by
the same and/or adjacent sensors.
The echoes are amplified, processed and returned to
the control module as a digital signal. The control
module processes this information and informs the
driver of the object by activating an intermittent
acoustic tone through the alarm.
The detection area is divided into five warning zones.
As listed in the following table, the tone-on to tone-off
period shortens as the distance to the detected object
decreases.

TOWING
W hen a towbar is f itted, the continuous tone activation area is inc reased from 30 to 45cm to allow f or the length of
the tow bar tongue. This is achieved by the towbar installer disconnecting the white wiring connector X906 (4 in
Figure 12F-4- Sedan or 12F -5- Coupe), c aus ing an open in the power supply circuit 24 and 796 to the control m odule
(pin 15). Refer to 4.2 WIRING SCHEMATIC in this Section.
When the c or rec t ac c es sor y trailer wiring har nes s is ins talled, the s ystem c an be temporar ily disabled when a trailer
or caravan, etc . is attached. The black connec tor X 907 ( 5 in Figure 12F-4-Sedan or 12F-5-Coupe) in circuit 650 and
471 is also disconnected by the installer and the grey wire in the trailer harness connected.
• W hile the trailer socket dust-flap is closed, a magnet in the dust-flap closes a reed-switch in the trailer socket
which connects this circuit to ground through circuit 22.
• W hen the dus t-flap is opened, as in connecting a trailer plug, the switch opens. The control m odule detects the
open circuit and disables the system.
If a bicycle carrier is fitted onto the towbar, a licence plate lamp and tail lamp should be fitted to the carrier and
plugged into the trailer socket. This will also temporarily disable the system, as it is highly likely the bicycles will
cause a disturbance to the detection field.

3. DIAGNOSIS
IMPORTANT: Where it is possible to touch connector pins, correct Electro-Static Discharge (ESD) protection
procedures, including the use of a grounded wrist strap and an anti-static mat, must be followed.
3.1 DESCRIPTION
The RPA is initialised once the ignition is switched on and reverse gear is selected. A ready tone will sound for a
period of 0.5 seconds. In this state, the rear object sensor control module continuously monitors the system and
should a fault be detected, a continuous 600 Hz tone will sound.
NOTE: Faults are stored in non-volatile memory within the control module while present. Past faults are not
retained.
The system can then be placed in diagnostic mode by grounding the light-blue wire connector X156 (1) on circuit
5213, located on the left- hand s ide of the rear com partm ent, pr ior to switching the ignition on and engaging rever se
gear, refer to Figure 12F-14, A – Sedan or B – Coupe.
Using the following table may assist in locating the fault area. However before replacing any components refer to
the following procedures for the relevant circuit diagnosis.
