The Audio Interface Module (AIM) is located in a mounting
bracket under the centre of the rear seat along with the DVD
player and video splitter.
The AIM acts as an interface between the DVD player,
audio system and BCM. The AIM enables the DVD to power
up by verifying BCM security information from the Radio
message on the UART data bus and then communicating to
the DVD via the Class II communications bus. Without the
valid security information, the AIM will go into Lock mode
and not allow the DVD to power up.
The AIM also controls the parental lockout feature. This
feature is activated by pressing the headphone button on
the AHU for more than two seconds. While in parental
lockout mode, all DVD functions except for load / eject DVD
are disabled. The rear remote controls are also locked when
this parental lockout is activated. Normal operation of the

The sockets are standard 6.5 mm size that suit a wide
variety of headphones.
Figure 12D – 16
Two sets of headphones are supplied with the vehicle when
new. Insertion of one or both headphones into the audio
output jacks mutes the audio output from the rear speakers
and switches the audio signal to the headphones.
NOTE
Two 3.5 mm jacks are incorporated into the front
of the DVD player. Suitable headphones are not
provided with the vehicle, as they do not support
the multi-mode rear seat audio operation. The
auxiliary headphones operate independently of
the audio system and only provide output of
DVD or auxiliary devices connected to the DVD
player RCA jacks.
When the supplied headphones are plugged in, multi-
moding of the audio system is possible via the rear remote
controls, refer to 1.5 Rear Remote Control. That is,
whichever function is not being used by the occupants of the
front seats can be used by the occupants of the rear seats
and vice-versa. This can only be achieved while the
headphones are plugged in.
If the headphones have been inadvertently left plugged in,
audio from the rear speakers can be regained without the
need for the driver to stop the vehicle and physically remove
the headphones from the jacks. Toggling the switch (Item
20, refer to Figure 12D – 3) on the radio fascia enables the
driver or front seat passenger to obtain audio output from
the rear speakers while the headphones remain plugged in.

Serial Data Bus
The audio system is connected to the main vehicle serial data bus and communicates with other modules on the bus.
Some audio system settings can be displayed on the Multi-function Display (MFD) located in the instrument cluster, and
this information is transmitted via the serial data bus. Additionally, the instrument cluster Customisation Mode allows the
adjustment of some audio system settings from the instrument cluster.
The serial data bus transmits all audio settings to the Multi-function Display (MFD), located in the instrument panel centre
trim via the secondary serial data bus.
When the audio system is switched off at the front panel switch, power is still applied to the unit to maintain serial data
bus communications.
Security System
The audio system is protected by a security system, which flashes a red LED on the front fascia when activated. In
addition, the audio system is protected against theft by a four-digit security code that is unique to each unit.
The audio system communicates with other modules such as the BCM and the instrument cluster on the UART serial
data bus. If the audio head unit is removed for any reason, upon installation the audio system interrogates the other
modules to determine if the same modules are fitted and therefore the system or vehicle is the same. If the audio system
recognises the other modules the audio system will operate. However, if the audio system detects a mismatch in the
serial numbers of some of the other modules, the audio system will remain in secure mode indefinitely. Entry of the
correct security code via the head unit preset keys will enable operation and authorise a new link up of the modules on
the serial data bus.
The instrument cluster monitors communication over the serial data bus. If a different AHU is fitted to the vehicle, and
this AHU is not connected to the bus, the Data Trouble Code (DTC) associated with the audio system may be
permanently set. This fault does not have a visible telltale on the instrument cluster.
For Type 2 entertainment systems, the AIM provides a secondary security feature. The AIM enables the DVD to power
up by verifying BCM security information from the Radio message on the UART data bus and then communicating to the
DVD via the Class II communications bus. Without the valid security information, the AIM will go into Lock mode and not
allow the DVD to power up. The AIM can be linked to the BCM via Tech 2.
Telephone Audio
The audio head unit provides two inputs for telephone audio, which allows the telephone audio to use the audio system
speakers, where the correct hands-free kit is fitted. A mute signal from the telephone mutes the normal audio or pauses
the CD when required. The audio system display shows VOICE IN when the telephone is in use. When the call ends, the
audio system returns to the previous playing mode and audio settings. For more details,
refer to Section 12G Cellular Phone.
Telematics (Type 2 Entertainment System) also uses these circuits for muting normal audio and providing telematics
audio through the vehicle's speakers. For more details on telematics, refer to Section 12K Telematics.

1.2 Radio Control Switch Assembly
Operation
There are two major components of the radio control switch
assembly. These components are as follows:
Left-hand Switch Assembly (1)
Located to the left-hand side of the steering wheel, the left-
hand switch assembly has three momentary contact
switches used to control the mode of operation and
switching between preset stations.
The MODE button allows selection between the Radio Mode
of operation and the CD Mode.
If Radio Mode is selected, the NEXT UP button selects the
next preset station in the frequency band, while the NEXT
DOWN button selects the previous preset radio station.
If CD Mode is selected, the NEXT UP button selects the
next track on the CD, while the NEXT DOWN button selects
the previous track. For CD Changer models, pushing the
NEXT UP and NEXT DOWN buttons simultaneously
changes the disc.
Right-hand Switch Assembly (2)
Located to the right-hand side of the steering wheel, the
right-hand switch assembly has three momentary contact
switches used to control the MUTE function as well as the
VOLUME UP and VOLUME DOWN.
Figure 12D – 20
Each control switch has a unique resistance value. When a button is pressed on the radio control switch assembly, the
AHU decides the function required by measuring the resistance of the contact pressed.
Wiring (3) from the right-hand switch is connected to the left-hand switch. The left-hand switch is connected to the audio
head unit by a wiring loom (4), as shown in Figure 12D – 20.
A Multi-function Display (MFD) in the instrument panel can provide the driver with an almost line-of-sight view of the MFD
for ease of operation of the audio system from the horn bar buttons.
Normal display on the MFD during vehicle operation displays the normal trip computer functions, for example the
odometer (in the centre of the MFD screen) and the gear selector position (displayed at the bottom of the MFD screen at
all times).
When the radio or a CD source is selected, the radio band and frequency or the CD symbol replaces the trip computer
display for 2 seconds. The display then reverts to the trip computer display with the radio band and frequency or CD and
track indicator changing to a secondary small icon located in the warning icon location on the left-hand side of the MFD.
NOTE
If a warning is activate, the warning will override
the CD and track indicators.
The display of audio system information on the MFD can be turned on or off from the MFD. The default setting is on.
Refer to Section 12C Instrumentation for further details.
Entertainment System Page 12D–26
Page 12D–26
1.3 Power Antenna Operation
Antenna Adjustable Height System Operation
When the ignition key has been turned on and in the case where the radio was on last time the ignition was turned off,
the antenna mast extends to the same height as it was when last in operation. If a Priority Key feature is used, the
antenna height at ignition ON or ACC position will be different for each priority key used.
If the battery is disconnected, the antenna height memory setting defaults to 5 seconds of mast upward travel after the
battery is reconnected, which raises the antenna approximately 600 mm.
Antenna height memory can be set and stored for the Priority 1 and Priority 2 keys. When the UNLOCK button on the
remote coded key is pressed, the antenna height is recalled by the BCM based upon what priority key (1 or 2) is being
used.
The information for antenna height memory and the pressing of the antenna UP or DOWN buttons is communicated to
the BCM via the Secondary Serial Data Bus.
The antenna mast is moved when either an antenna up or antenna down signal from the radio is received by the BCM
via the serial data bus. The pressing of these switches does not affect the antenna if the BCM does not sense the radio
ON signal or the ignition switch has not been switched in either the ACC or the ON position.
When the radio is turned off, the antenna operates as follows:
1 If the ignition is turned off, there is a delay of approximately 15 seconds before the antenna mast fully retracts.
2 If the ignition is turned on or to the ACC position, the antenna mast will fully retract after 3 seconds.
The antenna mast also retracts when the theft deterrent system is armed or a CD is played.
During engine starting, the radio on signal is momentarily lost. During this time, the BCM assumes the signal is still active
as it senses ignition and accessories inputs, as well as the radio status signal. This ensures unaffected antenna
operation and control during engine cranking.
Entertainment System Page 12D–27
Page 12D–27
1.4 Diversity Antenna Operation
When listening to FM signals in a vehicle, fading of the signal occurs because the radio station’s transmitted signal can
arrive at the antenna from different directions and cause cancelling of the signal even when the vehicle is in a strong
reception area. A diversity antenna system can help overcome this problem by using two antenna systems which receive
the same FM signals. The AHU determines which of the two antennas has the strongest signal strength, and switches its
input to be connected to the best antenna until the signal strength situation changes.
The entertainment system uses the power antenna as the main antenna and the rear glass antenna as the diversity
antenna.
The diversity antenna is an integral part of the rear window glass. The thin conductors that form the diversity antenna are
laid on the inside of the glass in the same manner as the rear window demister elements. A terminal is located on the
passenger side of the rear window allowing connection of the diversity antenna to the diversity antenna module lead.
The diversity antenna module amplifies the small signals from the diversity antenna to signals of similar strength as the
signals from the main (mast) antenna. It then transmits the amplified signal to the AHUs diversity antenna input.
The AHU receives signals from both the diversity antenna system and the conventional fender mounted mast type
antenna. Internal circuitry within the radio decides which antenna is located in the cleaner signal area. It then uses that
antenna for its radio reception.
Entertainment System Page 12D–28
Page 12D–28
1.5 Rear Remote Control
On vehicles fitted with Type 2 and Type 3 entertainment systems, rear passengers can access a rear remote control (1),
which is fitted to the centre of the headlining (2) forward of the rear passenger compartment, refer to Figure 12D – 21.
The AHU contains a lock-out function for the rear remote controls to prevent rear seat passengers from adjusting the

3 Preliminary Diagnostics
3.1 General Diagnostic Information
This audio system diagnosis is split into several parts.
1 The first part is a short description of the principles of radio operation. It is by no means exhaustive, and is to serve
only to give an understanding of how radios work and how to solve problems if they occur.
2 Many radio problems are caused by basic grounding and short-circuiting problems, which can be found quickly
using the checks included in the Basic Checks in this Diagnosis Section.
3 The most common fault is that of ‘static’ and so an explanation of what it is, what causes it and how to fix it is also
included.

3.2 Principles Of Operation
Radio Reception
High quality radio reception is obviously more difficult to achieve in a moving vehicle than from a stationary location.
Audio systems fitted to vehicles incorporate sophisticated electronics to enhance radio reception by extending the
useable listening range whilst eliminating extraneous noises, such as static.
Many owners complain of ‘reception problems’, which are normal radio operating characteristics, particularly with FM.
Such complaints arise as a result of owner misconception as to what constitutes normal radio reception. Naturally, audio
head unit replacement under these circumstances will not affect the radio operating characteristics and has the potential
to create additional owner dissatisfaction. Thus a careful, well informed explanation of radio reception expectations is
more likely to enhance the owner’s understanding and satisfaction, as well as avoiding unnecessary repair costs and
inconvenience to the owner of the vehicle.
FM Reception In Vehicles
FM stereo’s maximum range is normally limited to 40 to 50 km. The strength of the FM signal is related to the distance
between the receiver and the transmitter. FM signals follow the line of sight, exhibiting many similar characteristics to
those of light. That is, similarly to sunlight, FM radio waves are cut off by the horizon. Since most FM transmitter towers
are nominally 100 metres from the ground, useable reception cannot extend much beyond the horizon. FM signals will
not bend around corners, but as with light, may be reflected (or blocked) by large objects. Refer to Figure 12D – 23.
Figure 12D – 23
Legend
1 Radio Transmission Tower 2 FM Transmission (40 – 50 km) 3 AM Transmission (up to several hundred
km)
Although FM signals will not bend around corners, they can be reflected by large objects, for example hills or buildings.
Because of these characteristics, a reflected signal and a direct signal can reach the radio’s antenna at the same time,
resulting in the signals interfering with each other or cancelling each other out. This obviously leads to a distortion of the
received signal or a loss of sound, and is known as multi-path interference.
Multi-path interference occurs only with FM reception and can be characterised by changes in distortion (static) levels
occurring as the vehicle is moving. This is due to the vehicle’s antenna entering and leaving FM signal interference
areas.
FM signal waves have short wavelength, which also means the interference area is small – in the region of several
centimetres across. Because of the small size of interference areas, a vehicle may pass through many in a short time.
When the vehicle is stationary in an interference area, moving it half a metre can place the antenna in a region of clear
signal.
A vehicle fitted with a two antenna FM diversity system helps reduce multi-path interference by ensuring at least one
antenna is outside the cancelled signal region.
Flutter or fading is caused when a vehicle passes into an area where the direct signal can be overshadowed by a
building, large structure or hill. Refer to Figure 12D – 24.
Entertainment System Page 12D–32
Page 12D–32
Figure 12D – 24
Legend
1 Main Signal Path 2 Multi-path Signal 3 Shadowed Signal
Atmospheric conditions can also affect FM reception. Unexplained loss of sensitivity can be caused by high humidity.
Cloudy days are also better for reception than clear days. With electronic tuning radios, users can sometimes be
confused by abbreviated radio station call signs. People who tune their radios to abbreviated call signal frequencies may
be slightly off the correct frequency.
Entertainment System Page 12D–33
Page 12D–33
AM Reception in Vehicles
In contrast to FM signals, AM signals will bend around corners and skip along the ground. This is due to AM signals
having longer wavelength and lower frequency. The layer of atmosphere known as the ionosphere can reflect the signal.
This phenomenon gives AM a longer reception range than FM, especially at night. Refer to Figure 12D – 25.
Figure 12D – 25
Legend
1 Radio Transmission Tower 3 AM Transmission
2 Ionosphere 4 FM Transmission
AM reception is affected by static induced by electrical power lines, traffic lights, electronic signs and thunderstorms.
Fade of AM signals can also be expected when driving through tunnels, underpasses, and in city centres.

Entertainment System Page 12D–34
Page 12D–34
As shown in Figure 12D – 26, signals from radio stations are picked up by the antenna and fed to the radio while being
shielded from interference sources by the braid. This is a complete electrical circuit, any breaks in the circuit, such as
poor connections, will result in poor reception.
Interference is due to the antenna system picking up signals other than those from the desired station. These
undesirable signals may be produced by electrical equipment in the vehicle itself, such as ignition, which is termed
‘internal interference’. Conversely, interference from sources outside the vehicle, such as from power lines, is known as
‘external interference’.
Internal interference is minimised by the shielding around the antenna wire, which prevents internal noise being picked
up and fed to the radio. The shielding around the core takes the form of a ‘braid’, which completes the electrical circuit
along which signals travel to the radio. Faults in this shielding system allow interference to reach the radio and hence be
reproduced at the speakers as noise.
It is therefore important the shield of the antenna cable is effectively grounded at both the radio (to the radio case) and at
the antenna end (to the vehicle body), to ensure minimal interference is received by the radio, and the optimum radio
sensitivity is achieved.
Basic Checks
Proper performance of the audio system depends greatly on grounding of the antenna and radio case to the vehicle
body, as it eliminates stray currents in the antenna circuit. Stray currents may be induced by wires running parallel to the
path of the radio or antenna wiring, or may be due to ‘noisy’ in-vehicle electrical items.
Resistances or connection quality of the major parts of the radio can be checked with a multimeter set to measure
resistance.
When using a multimeter to measure very low resistances, the lead resistance becomes considerable, and must be
subtracted from all subsequent readings. That is, touch the leads together, note the reading, and subtract this from all
subsequent readings.
NOTE
A very good contact point is required to measure
ground resistance. This point must not have
current flowing through it during measurement,
therefore ensuring the ignition is turned off. Avoid
measuring using the screw on the door jamb
switch. The best place to measure ground
resistance is to use one of the self-tapping
screws retaining the A-pillar drip rail. Since these
screws are sometimes not correctly grounded,
one of the screws may be removed to take
measurements directly to the body sheet metal.
1 Disconnect the battery negative terminal. Refer to
Section 00 Warnings, Cautions and Notes.
NOTE
Failure to disconnect the battery negative
terminal may lead to incorrect resistance
measurements due to stray currents.
2 Disconnect the antenna extension lead from behind
the passenger side hinge pillar trim assembly.
3 Measure resistance from the outer of the antenna lead
to the vehicle body (1).
Resistance reading 0.3 Ω maximum.
4 Measure resistance from outer of the antenna
extension lead to the vehicle body (2).
Resistance reading 0.6 Ω maximum.
Figure 12D – 27
Entertainment System Page 12D–35
Page 12D–35
5 Check continuity of the path from the antenna cable
core to the antenna mast by measuring resistance (1).
Resistance reading 0.4 Ω maximum
NOTE
This test can in fact only be performed on power
antennas, since manually operated antennas are
fitted with in-line capacitors with the antenna
body, which misleadingly indicates an open
circuit when resistance is measured.
On vehicles with manually operated antennas,
disconnect the antenna lead from the antenna
lead extension and measure the resistance of
the extension lead cable core from the radio to
the antenna lead connection ends.
Resistance values significantly higher than those
specified indicate poor connections that must be
rectified before proper radio performance can be
obtained. Figure 12D – 28
6 Check for shorts between the antenna core and the braid by disconnecting from the radio and measuring the
resistance between the two. The measured value should indicate an open circuit (very high or infinite resistance).
7 Disconnect the antenna extension lead at both ends and test the core for continuity.
Common Radio Problems
Static
Static is a buzzing or crackling noise caused by the radio picking up unwanted radio waves and converting them to noise
output by the speakers.
The unwanted radio waves (interference) come from several sources, which can be put into two groups; internal and
external. As the names suggest, external interference comes from outside the vehicle, and is difficult to control, while the
vehicle generates internal interference.
It must be emphasised that a radio system in good condition will protect itself from much static. Before trying to locate
and remove a source of interference it must first be determined the shielding and grounding of the radio is in good
working order. This can easily be done by performing the tests detailed in the ‘Basic Checks’.
It should be noted that static may occur on weak stations, or when driving under bridges because signals from ignition
and the like become relatively stronger than the radio station signal, causing the ignition interference to become quite
strong. This could be due to stronger than normal ignition interference or a poorly functioning antenna.
If the cause cannot be isolated after performing the tests and trying to isolate a source of interference, using the following
procedures, it may be the radio has an internal fault and requires repair.
External Interference
Static that occurs only while travelling in certain localities, such as near electrical transformers, is undoubtedly external
interference.
If there is any doubt whether the suspected source is causing interference, a simple check is to stop the vehicle and turn
off everything but the radio. If the source is external, the interference will continue and little can be done to eliminate it.
NOTE
The perceived interference level can be
significantly reduced, in noisy environments, by
slightly reducing the treble on the radio tone
controls.
Entertainment System Page 12D–36
Page 12D–36
Internal Interference
Internal interference is that caused by some component of the vehicle’s electrical system, and may take many forms.
Many of the electrical items fitted to motor vehicles produce some sort of radio waves, but these radio waves only
become a problem if they are in the range of frequencies at which the radio receiver picks up and reproduces signals as
sound. For the radio, the vehicle’s electrical system must be designed not to emit radio signals at the frequencies of the
AM and FM bands.
Components are sometimes fitted with suppressing devices as part of their design, and failure of these suppressors may
allow the item to start interfering with radio operation.
Interference will be worse on weak stations, since a strong signal normally overpowers the interfering signal. Interference
can occur when the signal strength drops below a certain threshold, such as driving under a bridge, inside a workshop,
or in the shadow of a building. This situation is shown in Figure 12D – 29.
Figure 12D – 29
Legend

2 In-vehicle Noise Interferes with
Tuned Station
4 In-vehicle Noise 6 Reception Blocked
Static may be caused by many internal sources. If static is at ignition frequency, varying with engine speed, the ignition is
the culprit. However, many electrical faults will cause static which otherwise would not be heard. Examples of ignition
interference sources are:
1 Plug leads breaking down.
2 Carbon tracking (arcing) to ground.
3 Faulty spark plugs.
4 Inoperative interference shields.
The actual cause of the interference can be isolated through carefully noting the circumstances under which the problem
occurs. For example, if it occurs only at speeds above approximately 80 km/h in an automatic transmission equipped
vehicle quite possibly it is the electrical signal being sent to the torque converter clutch.
Other sources of static can be:
1 Electric cooling fan.
2 Electric fuel pump.
3 Normal computer ‘noise’ at certain frequencies.
4 Windshield wipers or washers.
Entertainment System Page 12D–37
Page 12D–37
Diagnosing Internal Interference
If a vehicle has an interference problem that only occurs when the engine is turned on, or some other repeatable
circumstance, carry out the following procedure:
1 Park the vehicle in an open area, as far away from buildings as possible. Turn the radio onto the band (AM\FM)
and frequency where the complaint occurs, with the ignition in the Accessories position.
2 Reproduce the interference, eg. turn the ignition on.
3 If interference is due to a fan blower motor, etc. and is judged to be objectionable, try a similar specification vehicle
in the same location. If this is not possible, the component should be substituted to determine whether it is faulty.
NOTE
Internal interference is often a symptom of a
defective radio system, such as poor antenna
grounding, etc. If substituting a new component
does not fix the condition, the problem is very
likely to be in the radio system, and the
resistance checks in this section should be
performed.
4 Whistles / squeals that occur only when the ignition is on, are probably due to electronic modules in the vehicle
creating interference when active (power applied). These modules may be isolated as a cause of interference by
removing power to them and rechecking. This is best done by turning the ignition off, removing the fuse that
supplies that particular item with power, turning the ignition back on and rechecking. By process of elimination, the
‘noisy’ module should be able to be found. Once found, substitute the module to find out whether the interference is
normal.
Speakers
Before removing speakers suspected of being noisy or faulty, ensure any distortion that may be present is not due to any
of the following:
1 Foreign matter such as sand lying on the speaker cone, especially horizontally mounted speakers such as the
subwoofers.
2 Cable ties or other such material resting on the back of the speaker cone.
3 Incorrectly fitted speaker mesh or loose trim around speaker assembly.
4 Distortion of the speaker assembly caused by the angled insertion of the speaker retaining screws. Loosening and
tightening the screws while being careful not to distort the speaker cone may rectify the speaker problem.

4 Tech 2 Processor Diagnostics
Fault diagnosis for the audio system is divided into two areas; faults which can be remedied by checking the operation of
audio system and it's sub components (DVD Player, Audio Interface Module (Type 2 entertainment system only) and
Premium Sound Amplifier), and those which can be checked by using the Tech 2 Diagnostic Tool.
Diagnostic Trouble Codes
When a fault is detected, the audio system or it's sub component sets a Diagnostic Trouble Code (DTC) that represents
that particular problem or failure. The DTC remains current as long as the fault remains, and is cleared when the fault is
rectified. The DTCs can be read and cleared using Tech 2.
Each DTC is allocated a number. For further details on each of the DTCs,
refer to 4.4 Diagnostic Trouble Codes – Audio System.
Audio System Input / Output Signals
Voltages in the following table are typical voltages that will be read at the audio head unit connector while the radio is on,
ignition is on and the radio is in AM or FM mode. Some variation in the values can be expected due to changing battery
voltages and normal tolerances.

• Occurrence Count (0 to 255): The occurrence count is the number of times the particular fault condition has been
detected.
• History Count (0 to 255): The history count is the number of ignition cycles that have occurred since the fault was
last detected. A count of 0 indicates the fault has occurred on the current ignition cycle, while a count of 255
indicates the fault occurred 255 or more ignition cycles ago.
When a DTC is first set, the occurrence count sets to 1 and the history count is set to 0. The history count determines the
age of a DTC. If the DTC already exists, then the occurrence count will be incremented (up to 255, at which point it is no
longer incremented), each time the DTC is set, the history count is cleared.
The occurrence and history counters provide a means of determining how often the fault has occurred, and how long it
has been since the fault last occurred. For instance, if the DTC occurrence count is 1, and the history count is 201, then it
can be determined the fault condition existed only once, and it happened 201 ignition cycles ago (and has not been
detected since). Another example would be an occurrence count of 4 and a history count of 0. This would indicate the
fault has been detected a total of four times, and that it was detected on the current ignition cycle.
Current and History DTCs and DTC history data can be read and cleared using Tech 2.

4.15 Premium Sound Amplifier Diagnostic
Procedures
PSA Diagnostic Circuit Check
Introduction
The Premium Sound Amplifier (PSA) delivers high power to all of the upgraded vehicle speakers. The four channel
sound output from the audio head unit is taken to the amplifier where it passes through a DSP system before being
amplified and sent to the vehicle speakers. The amplifier is internally protected by two fuses against short circuits and
connection to voltage sources on the speaker wires.
The PSA is connected to the main vehicle communications bus, and therefore has its own Tech 2 diagnostic capability.
The serial data communications between the PSA and the BCM and audio system is via circuit 1061 to terminal X1-12.
The high power requirements of the PSA mean the power supply and earth circuits are very important to ensure smooth
operation. Carefully inspect each connection to make sure they are tight and free from corrosion. The PSA is supplied
with power from the main battery via circuit 1540 to connector N7 – X2 pins 1, 2 and 5 and from the accessory control
relay via circuit 43 to connector N7 – X1 pin 9 . Connection to vehicle ground is made on connector N7 – X2 pins 2, 4
and 6, via circuit 650.
Refer to 5.2 Wiring Diagrams and 5.3 Connector Chart to aid in diagnosing the premium sound amplifier.

4.16 Diagnostic Trouble Codes – Audio
Interface Module, Type 2 Entertainment
System
Diagnostic Trouble Code History Data
When the Audio Interface Module (AIM) detects an operating parameter which is outside its calibrated values it will set a
Diagnostic Trouble Code (DTC) and store this DTC into its memory as a current DTC.
When a DTC is set the AIM also stores the following history data for each DTC:
• DTC Status: Current or History
• DTC Number: The DTC number is the number used to identify a particular fault condition.
• Occurrence Count (0 to 255): The occurrence count is the number of times the particular fault condition has been
detected.
• History Count (0 to 255): The history count is the number of ignition cycles that have occurred since the fault was
last detected. A count of 0 indicates the fault has occurred on the current ignition cycle, while a count of 255
indicates the fault occurred 255 or more ignition cycles ago.
The AIM is capable of storing history data for up to ten DTCs. Therefore, if more than ten DTCs are set, only history data
for the last ten will be tracked. That is, the history data for the oldest DTC will be removed from the AIM. Once a DTC
history data has been removed, it is maintained in the memory of the AIM as a History DTC, however there will be no
DTC history data available for this DTC.
When a DTC is first set the occurrence count is set to 1 and the history count is set to 0. The history count determines
the age of a DTC. If there are more that ten DTCs, the DTC with the highest history count will be removed to make space
for the new DTC. If the DTC already exists, then the occurrence count will be incremented (up to 255, at which point it is
no longer incremented). Each time the DTC is set, the history count is cleared and this ensures the ten most recent
DTCs are tracked.
The occurrence and history counters provide a means of determining how often the fault has occurred, and how long it
has been since the fault last occurred. For instance, if the DTC occurrence count is 1, and the history count is 201, then it
can be determined the fault condition existed only once, and it happened 201 ignition cycles ago (and has not been
detected since). Another example would be an occurrence count of 4 and a history count of 0. This would indicate the
fault has been detected a total of four times, and that it was detected on the current ignition cycle.
Current and History DTCs and DTC history data can be read and cleared using Tech 2.

AIM Diagnostic Circuit Check
Introduction
The Audio Interface Module (AIM) enables the DVD to power up, firstly by verifying BCM security information from the
Radio message on the UART data bus, then communicates to the DVD via the Class II communications bus. The AIM
will power up when the Accessory control relay is enabled. This power source is available when the ignition is in ACC or
ON position, or when the audio head unit is switched on, refer to Section 12J Body Control Module for more details.
Without the valid security information, the AIM will go into Lock mode and not allow the DVD to power up.
NOTE
If the AIM is disconnected from the wiring
harness (such as when the dead pan assembly is
removed) it loses its link with the BCM. To link
the AIM to the BCM refer to 4.20 Security –
Audio Interface Module, Type 2 Entertainment
System.
The AIM also controls other DVD operations, such as Parental Lockout or Rear Roof Remote Locked and DVD
background illumination. This is done through the inputs from the audio head unit and BCM respectively via
communication on the UART data bus to the AIM, then commands are then transmitted to the DVD via the Class II bus.

4.27 DVD Player Diagnostic Procedures,
Type 2 Entertainment System
DVD Player Diagnostic Circuit Check, Type 2 Entertainment System
Introduction
The WL AIM enables the DVD to power up, firstly by verifying BCM security information from the Radio message on the
UART data bus, then communicates to the DVD via the Class II communications bus. If BCM security information is
verified, the DVD player will power up when the Accessory control relay is enabled. This power source is available when
the ignition is in ACC or ON position, or when the audio head unit is switched on,
refer to Section 12J Body Control Module for more details.
Without the valid security information, the AIM will go into Lock mode and not allow the DVD to power up.
The DVD player communicates with Tech 2 via the AIM. If the AIM is not functioning, diagnosis of the DVD player via
Tech 2 is not possible. For this reason, all diagnosis of the DVD player must begin by verifying the AIM is fully functional.
NOTE
If the AIM is disconnected from the wiring
harness (such as when the dead pan assembly is
removed) it loses its link with the BCM. To link
the AIM to the BCM refer to 4.20 Security –
Audio Interface Module, Type 2 Entertainment

DVD Player Diagnostic Circuit Check, Type 3 Entertainment System
Introduction
The DVD player powers up by firstly verifying BCM security information from the Radio message on the UART data bus.
If BCM security information is verified, the DVD player will power up when the Accessory control relay is enabled. This
power source is available when the ignition is in ACC or ON position, or when the audio head unit is switched on,
refer to Section 12J Body Control Module for more details.
Without the valid security information, the DVD player will go into Lock mode and not power up. The DVD player also
controls other operations, such as Rear Roof Remote Lockout and DVD background illumination. This is done through
the inputs from the audio head unit and BCM respectively via communication on the UART data bus to the DVD player.
NOTE
If the DVD player is disconnected from the wiring
harness (such as when the dead pan assembly is
removed) it loses its link with the BCM. To link
the DVD player to the BCM refer to 4.34 Security
– DVD Player, Type 3 Entertainment System.

• Power On / Off • Audio Head Unit Illumination
• No Sound or Distorted Sound - Level 4 Vehicles • Hands-free Telephone Unit
• No Sound or Distorted Sound - Level 5 Vehicles • Electric Antenna – Height Adjustable
• Rear Seat Headphones No Sound • CD Changer
• Rear Remote Control • Radio Reception
• Multi-function Display • Subwoofer Amplifier
Diagnostic tables contained in this section, list both technical problems and common faults found due to incorrect use of
the audio system. Refer to 5.2 Wiring Diagrams and 5.3 Connector Chart to aid in diagnosing the audio system.
It is advantageous to read the Audio System Handbook Supplement supplied with the vehicle before performing
diagnosis on the system.
When carrying out wiring checks as directed by the diagnostic charts, rather than probe terminals and connectors with
incorrect sized multimeter connections, use the adaptors contained in connector test adaptor kit J35616-A (KM609). This
will prevent any possibility of spreading or damaging wiring harness terminals, which may later cause a system
intermittent failure. Refer to 5.3 Connector Chart for various connectors associated with the audio system.
Before commencing any diagnostic procedure, the Audio System Diagnostic Circuit Check should be carried out to
ensure a known starting point, refer to 5.4 Audio System Diagnostic Circuit Check.
5.1 Prerequisites
Equipment
The following equipment is required to diagnose the entertainment system:
1 An unpowered test lamp with a current draw of less than 3 A.
2 A digital multimeter with a minimum impedance of 10 MΩ.
Testing Procedures
Adhere to the following points when performing diagnostic testing on navigation system components:
1 Take care when using testing equipment to diagnose wiring harness connectors. The technician should backprobe
the connector to avoid terminal damage.
2 When tests are required on connector terminals, use the adapters in the connector adapter kit KM–609 to prevent
damage to the terminals.
3 Unless the multimeter being used has an auto-ranging function, ensure the correct range is selected.
4 When backprobing connectors, ensure the test lamp ground lead is connected to an appropriate ground point on
the vehicle. Ensure this ground point is not part of the circuit being tested.
NOTE
When following the steps in the diagnostic tables,
ensure work is performed in the order in which
they are presented. If the required nominal value
or result is not achieved, rectify the problem
before proceeding.

5.6 No Sound Or Distorted Sound – Type 1
Entertainment System
Introduction
Type 1 Entertainment Systems have modern amplifiers that deliver high power and are internally protected against short
circuits and connection to voltage sources.
The entertainment system features a high powered 4 x 30 W RMS amplifier that drives 2 Ω speakers in the doors and
tweeters in the instrument panel. The entertainment system also have two subwoofers driven by a separate 2 x 40 W
RMS amplifier fitted to the parcel shelf to increase the frequency response of the system.
All audio head unit has a Distortion Limiting circuit. This circuit, when turned on, automatically limits the volume level to
the point where distortion begins. The amount of distortion will depend on the amount of bass in the music. Listeners who
find the music does not play loud enough with the distortion limiting circuit activated can either:
• reduce the amount of bass, or
• turn the distortion limiting off using the instrument cluster MFD, refer to Section 12C Instrumentation.
Damaged speakers and wiring may not cause a failure when played at low volume levels. At low volume the amplifier
may cope with the additional load caused by the damage. Problems may only become obvious when playing at loud
volume levels. Typical symptoms will be
• one speaker dropping out,
• two speakers dropping out, or
• all speakers dropping out.
When the amplifier has cooled, the output may resume from the affected speaker or speakers.

5.7 No Sound Or Distorted Sound – Type 2
and Type 3 Entertainment System
Introduction
Type 2 and Type 3 entertainment systems include a Premium Sound amplifier mounted in the rear of the car that delivers
high power to all of the upgraded vehicle speakers. The four channel sound output from the audio head unit is taken to
the amplifier where it passes through a DSP system before being amplified and sent to the vehicle speakers. The
amplifier is internally protected against short circuits and connection to voltage sources on the speaker wires.
The Type 2 and Type 3 entertainment systems has a Distortion Limiting circuit. This circuit, when turned on,
automatically limits the volume level to the point where distortion begins. The amount of distortion will depend on the
amount of bass in the music. Listeners who find the music does not play loud enough with the distortion limiting circuit
activated can either:
• reduce the amount of bass, or
• turn the distortion limiting off using the instrument cluster MFD, refer to Section 12C Instrumentation.
Damaged speakers and wiring may not cause a failure when played at low volume levels. At low volume the amplifier
may cope with the additional load caused by the damage. Problems may only become obvious when playing at loud
volume levels. Typical symptoms will be
• one speaker dropping out or sounding distorted,
• two speakers dropping out, or
• all speakers dropping out.
When the amplifier has cooled, the output may resume from the affected speaker or speakers.
The Premium Amplifier is connected to main vehicle communications bus, and therefore has its own Tech 2 diagnostic
capability. The high power requirements of the Premium Amplifier mean the power supply and earth circuits are very
important to ensure smooth operation. Carefully inspect each connection to make sure they are tight and free from
corrosion.

Introduction
The audio head unit has full night illumination for easy operation. With the accessories and ignition turned on, the display
is illuminated to make the clock easy to read. When the park lamps are turned on the display and buttons are fully
illuminated. The audio head unit uses two signals to determine the illumination state:
• Park lamps switch to determine if illumination should be off or on.
• Dimming value from the vehicle serial communication bus to determine the illumination brightness.
Testing the operation of illumination functions will be easier if the vehicle is in a darkened area.

5.12 Hands-free Telephone Input
Introduction
The Audio System has an electrical interface for a mobile telephone hands-free kit that may be used to:
• Mute the radio when a phone call is in progress.
• Play the caller’s voice through the car speakers instead of the hands-free speaker.
Using this circuit has the advantage of automatically silencing the radio or CD so the telephone can be heard without
distraction, and playing the voice through a higher power, higher quality sound system. When the voice is played through
the audio system the volume, bass and treble can be set to the best listening levels. The Independent Tone Memory will
always recall these settings when a phone call is received.
When the hands-free controller grounds the audio system mute input on terminal A133 – X1 pin A3, the audio system
automatically switches to Phone Mode, which is confirmed by the display showing ‘VOICE IN’. When in Phone Mode the
audio system switches to the telephone input lines on connector A133 – X1 pins C7 and C8. Any signal at those inputs
will be played through the audio amplifier and vehicle speakers. The inputs are high impedance, differential type that
accept a wide range of inputs from the majority of phone kits on the market. Connect the hands-free kit speaker lines
direct to these terminals; do not connect the hands-free speaker.
NOTE
Mobile phone signal quality can vary greatly
affecting the quality of the sound through the
speaker. When diagnosing phone type problems
it is recommended to move the vehicle to an area
that has a strong signal.

5.13 Electric Antenna – Height Adjustable
Introduction
The entertainment systems include a height adjustable electric antenna system. In these systems the audio head unit
has up and down antenna buttons fitted. While in Radio Mode these buttons are used to raise or lower the antenna to a
height that suits the user. In CD Mode the buttons have no effect.
The adjustable height antenna is under direct control of the BCM. The audio system Radio On signal on circuit 314 is
applied to the BCM on terminal A15 – X3 pin 10 and, together with information on the serial data bus, instructs the BCM
to raise or lower the antenna. Antenna motor power is supplied via the BCM (terminal A15 – X4 pin 23) and is applied to
the antenna connector W6 – X1 pin A (circuit 160). Antenna direction control is also controlled by the BCM (terminal
A15 – X4 pin 7) and is applied to the antenna connector W6 – X1 pin B (circuit 161).
New Audio Systems are delivered with the antenna system disabled. This is to prevent the antenna raising and
potentially becoming damaged in the Vehicle Assembly Plant. As the vehicle passes through final testing the antenna
drive is enabled and will remain enabled thereafter. In the event of an antenna system not functioning, verify the antenna
system has been programmed correctly using Tech 2, refer to 4.8 Program – Audio System.

5.14 CD Changer
Introduction
The entertainment systems feature an integrated six-disc CD Changer built into the audio head unit. CDs are loaded and
ejected one at a time through the single slot on the fascia. Display messages, audible beeps and flashing of the fascia
LED co-ordinate the loading and removal of CDs. A seven second memory is fitted to prevent music interruption due to
strong vibration.
The CD Changer will play all commercially recorded 120 mm music CDs, and most CDRs that have been recorded using
good quality CD Writers. CD-RWs may not play satisfactorily. The CD Changer will not play non-standard sized CDs, eg
80 mm CDs. Using CDs smaller than 120 mm even with an adaptor may result in damage to the CD, CD Changer or
both.
The CD Changer uses a LOAD button on the fascia to start the loading process. Pushing CDs into the CD slot will not
cause automatic loading and may cause the mechanism to jam.
Foreign objects, eg credit cards, placed in the CD slot will prevent loading and unloading of CDs.
Loading two CDs at once will jam the mechanism.
The CD Changer cannot decode files recorded in compressed format, eg MP3.
CDs should not have labels attached to them. The label may peel off or buckle due to heat and rub or jam the CD
mechanism. Damage caused by these labels is not covered under warranty.
NOTE
In cases where fascia button damage or no
operation prevents a customer’s CD from being
ejected, use Tech 2 to remove the CD prior to
returning the unit for repair, refer to
4.7 Miscellaneous Tests – Audio System. Where
this is not possible and the unit is returned for
repair with a customer’s CDs trapped inside,
attach a note to the Exchange Request form
detailing:
• Name of CDs (for example Carmina Burana).
• Owner’s name.
• Owner’s mailing address, or Holden Retailer's
address – if CD is to be returned to the
customer by the Holden Retailer.
• Contact name and telephone number within
the Holden Retailer.
It is recommended the audio head unit does
not contain any CDs when being removed or
installed. Under some circumstances, a CD
may become dislodged it the unit is treated
roughly during removal or installation.

5.15 Radio Reception
Introduction
The audio system has a sophisticated radio tuner. Primary emphasis is on consistent sound quality without the effects of
external interference. The AM section has good sensitivity for weak stations and strong selectivity to prevent interference
from other stations. FM includes a multipath detection circuit to stop unwanted noise being amplified and a treble cut
circuit to reduce noise when signals are weak. The circuit is under continuous computer control to adjust its
characteristics as reception conditions vary. Apart from Local (LOC) and Distance (DX) search switching there are no
user adjustable parameters. For further information on radio frequencies, reception, interference and common radio
problems refer to 3.2 Principles Of Operation.
With Tech 2 it is possible to monitor the signal strength received by the radio. This is a good tool for diagnosing radio and
antenna problems. On models fitted with a diversity antenna, Tech 2 may be used to switch between the front antenna
and the diversity antenna for diagnostic purposes.
The diversity antenna system is used to minimise the normal disturbances associated with FM transmissions. Using the
two antennas the radio monitors the signal from both antennas and dynamically selects the antenna with the better
signal. Compared to a standard single antenna, this achieves a more even sound quality without the frequent
disturbances of a single antenna design. Refer to 5.17 Diversity Antenna Fault Diagnosis for details and diagnosis of the
Diversity Antenna.
Multipath Detector
The audio system has a special circuit to detect the presence of multipath in the FM signal. When multipath is detected,
the tuner switches to mono output mode so the multipath distortion is not heard. The computer requires several seconds
of multipath free reception before it will allow the output to return to full stereo. Due to this circuitry, the radio will
sometimes be in mono reception mode during city and urban driving where multipath is most common. The delay in
switching from mono to stereo is to reduce the effects of the music suddenly switching modes. Switching between mono
and stereo is often perceived as a volume change. In some cases the customer will notice the volume fluctuation,
particularly if a high value of treble has been selected in the audio setting.
Treble Control
When signals become weaker the background noise seems to become stronger. The background noise in fact remains
constant but the radio station is not strong enough to overcome it. In these circumstances the radio automatically
reduces the amount of treble (called High Frequency Cut) to help hide the background noise. The audio head units High
Frequency Cut is partially selectable with the LOCAL function. When in LOCAL mode, there is no High Frequency Cut. In
non-LOCAL Mode or Distance Mode, the treble is reduced by half to cut down on the background noise. It is
recommended to leave the LOCAL on to achieve the best performance from local radio stations.
NOTE
When performing radio diagnosis it is
recommended the vehicle be moved outside the
workshop. Radio signals are blocked by the metal
structure of most workshops making testing
difficult. AM particularly is affected by being in an
enclosed space. Radio reception varies
significantly with location. When testing for radio
performance it is advisable to have another car
available for a comparison check.
Vehicle interference is often caused by a bad earth connection within the vehicle. To isolate the source of interference
turn circuits on and off until the source of the noise is found, eg indicators, wipers, horn. Then study the circuit diagram
paying attention to the location of earth points, refer to Section 12P Wiring Diagrams. Check each earth point for
tightness and ensure that mating surfaces are free from corrosion.

5.16 Subwoofer Amplifier
Introduction
Type 1 Entertainment Systems are fitted with an auxiliary amplifier to improve the low frequency output of the system
using two parcel shelf mounted subwoofer speakers. The unit is a two channel, high powered design that features self-
protection circuitry to stop overload in the event of damage to wiring or speakers, or high temperatures. Signal inputs to
the amplifier are taken from the corresponding left and right rear door speakers, as per the system diagram, and the
signals are then combined to produce a mono output.
Output gain can be varied by turning the small adjuster mounted on the end of the casing at the opposite end to the
connector. The centre position is the default setting. From the centre position the subwoofer effect can be increased by
6 dB or decreased by 3 dB from the factory setting for customers who prefer more or less subwoofer effect. A 10 Amp
fuse mounted in the end of the unit will protect the wiring in event of an internal amplifier failure.

5.17 Diversity Antenna Fault Diagnosis
Before commencing the diagnostic procedure for the diversity antenna system the following should be checked:
• Determine whether the reception problem is apparent with FM, AM or both. Faults affecting both FM and AM
reception are not caused by the diversity antenna system due to the fact the diversity antenna system only affects
FM reception. The conventional fender mounted mast type antenna system is more likely to be cause of such
faults.
• Ensure the customer complaint is not due to normal operation or the limitations of FM transmissions. The diversity
antenna system is designed to minimise distortion in the sound quality of FM reception and not to give large
increases in FM reception range.
• Compare reception quality with that of another vehicle equipped with a diversity antenna system in the same
location and under the same conditions.
Diversity Antenna System Test Procedure
NOTE
When the vehicle’s conventional antenna is
lowered, disconnected or faulty, the radio will not
use the diversity antenna system to receive FM
radio signals. If no FM stations can be received
then the fault is not due to the diversity antenna
system.
Refer to 5.15 Radio Reception before commencing to diagnose a diversity antenna related system fault.
1 Remove the left-hand side still trim and plate
assembly, refer to
Section 1A8 Headlining and Interior Trim.
2 Remove the left-hand side body lock pillar lower trim,
refer to Section 1A8 Headlining and Interior Trim.
3 Remove the left-hand side hinge pillar trim assembly,
refer to Section 1A8 Headlining and Interior Trim.
4 Leaving the wiring harnesses connected to the
exposed module, manoeuvre the module from the
plastic mounting bracket.
5 Remove the plastic mounting bracket.
6 Disconnect the diversity antenna amplifier module
power cable (1).
7 Test the voltage at the diversity antenna module-to-
main wiring harness connector with the key in
Accessories position. If 12 V is indicated, continue with
next step. If 0 V is indicated, trace wire back to fault
and repair.
