SECTION 12D - AUDIO SYSTEMS

IMPORTANT

Before performing any Service Operation or other procedure described in this Section, refer to

Section 00 CAUTIONS AND NOTES for correct workshop practices with regard to safety and/or

property damage.

1. GENERAL I NFORMATI ON

All WH models are fitted with a high performance double DIN size AM/FM stereo radio/cassette player combination.

The audio systems fitted to both the WH Statesman and the WH Caprice comprise a radio/cassette player with a 6

disc CD player/changer installed in the rear compartment of the vehicle (refer to 2.12 COMPACT DISC PLAYER/

CHANGER INSTALLATION in this Section).

All radio/cassette player assemblies incorporate Personal Identification Number (PIN) security code theft deterrent

and flashing LED features.

WH vehicles have speakers mounted in each upper corner of the instrument dash panel, and are also equipped

with unique 150 mm diameter twin cone speakers mounted in the front door trim side pockets and 150 mm co-axial

speakers mounted in the rear door trim side pockets.

The audio system fitted to WH vehicles features personal identity memories which individually memorises the

following settings for different ignition keys:

Last used volume level

Last used mode

FM1- radio memory presets

FM2- radio memory presets

AM- radio memory presets

Bass control settings

Treble control settings

Speaker balance setting

Speaker fader setting

Time/Frequency priority settings

Local On/Off setting

Telephone volume

Caprice only:

Digital Signal Processor (DSP) effects

Pre-program Equaliser (EQ) setting

Listening Position (POS) selected

The audio system fitted to the WH vehicles also features a pair of subwoofer speaker and bracket assemblies,

mounted on top of the rear parcel shelf. These speakers are powered by an additional amplifier located in the left-

hand side of the rear compartment, refer to 2.13 SUBWOOFER AMPLIFIER in this Section.

A connector for cellular telephone installation on WH vehicles is located under the centre console to the left of the

transmission gear shift lever. Wiring from this connector is connected into the back of the audio system to enable

audio system muting when the telephone is in use. The WH Statesman and the WH Caprice are provided with a

six-pin connector, which enables a telephone with a hands-free kit to use the vehicle’s speakers and the radio

volume control for the telephone audio.

A mobile phone antenna and cable is fitted to all WH vehicles to simplify the installation of a GSM (digital) mobile

phone hands-free kit. The exterior portion of the glass mounted antenna is not fitted to the vehicle, but is supplied

with the vehicle for fitting if required. However, the interior portion of the antenna is fitted to the rear screen and is

connected to the phone antenna cable which runs to the left-hand kick panel area, where it is coiled and clipped to

the left-hand end of the glove compartment lower rail.

A feature of the radio fitted to WH vehicles is the smart switch. The radio can be switched on without the need for

the ignition switch to be turned to ACC position. After an hour, circuits within the radio sense the ignition has not

been switched on and will switch the radio off. However, the radio can be switched ON again and the process will

repeat.

Techline

Additional features fitted to the WH Caprice audio system are rear seat headphone jacks, rear roof-mounted

speakers and a roof mounted rear remote control unit, which enables independent audio control for the rear

passengers when using the headphones. The rear remote control unit also provides controls for the climate control

air conditioning.

The audio output jacks for the headphones are located beneath the flap on the rear parcel shelf, and positioned on

either side of the child restraint anchor point. Insertion of one or both headphones into the audio output jacks mutes

the audio output from the vehicle’s rear speakers and switches the audio signal to the headphones.

When the headphones are plugged in, multi-moding of the audio sy stem is possible via the roof-mounted rear

remote controls. That is, whichever function is not being used by the occupants of the front seats can be used by

the occupants of rear seat 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

(marked with the image of the headphones) on the radio facia enables the driver or front seat passenger to obtain

audio output from the rear speakers while the headphones remain plugged in.

The audio system for WH vehicles also includes steering wheel mounted audio system control buttons. Control of

the radio, tape and CD player functions can be accomplished without the need for the driver’s hands to be removed

from the steering wheel.

The radio reads the switch resistance from the steering wheel stereo controls via the clock spring coil harness.

WH vehicles are fitted with a power antenna, which is controlled by the Body Control Module (BCM) and the radio.

Refer to 2.8 POWER ANTENNA in this Section.

All WH vehicles have a height adjustable power antenna fitted as standard equipment. The power antenna

operation on these models is controlled via a switch located on the radio facia and in conjunction with the body

control module (BCM), refer to Section 12J-2 HIGH SERIES BODY CONTROL MODULE in of this Supplement.

To aid in the reception of FM radio signals a diversity antenna system is fitted to all WH vehicles.

The diversity antenna system consists of a diversity antenna, which is an integral part of the rear window glass, and

a diversity antenna module. The diversity antenna module is located under the rear parcel shelf trim on the

passenger side and amplifies the signal received by the diversity antenna. The amplified signal is sent to the radio

via a coaxial cable.

The radio receives signals from both the diversity and the fender mounted mast antenna and uses the stronger

signal for radio reception. This use of two antennae located in different positions on the vehicle makes the radio

reception less likely to be affected by signal nulls (multipathing) experienced in moving vehicles.

Operating instructions for the audio system accompany the WH Statesman & Caprice Owner’s Handbook in the

vehicle’s glove compartment.

1.1 POWER ANTENNA OPERATION

For WH Series vehicles, the operation of the power antenna is controlled by the body control module and a

height adjustment switch located on the radio/cassette/CD player control panel below and to the left of the

liquid crystal display. For service information refer to Section 12J-2 HIGH SERIES BODY CONTROL

MODULE of this Supplement.

For all vehicles, when the radio is turned ON, control circuitry within the radio supplies voltage to the Body

Control Module (BCM) for as long as the radio is on. The BCM then determines what voltage and for how

long it is supplied to the antenna motor. The motor raises the antenna mast to full height for optimum radio

reception. The height of the antenna can be adjusted via the control on the radio facia.

Approximately 15 seconds after switching the ignition and/or radio OFF, the BCM switches voltage to the

opposite side of the antenna motor, reversing the operation of the motor to retract the antenna mast fully.

1.2 DIVERSITY ANTENNA OPERATION

To aid the consistent reception of FM radio signals, WH vehicles are equipped with a diversity antenna

system. This antenna system is designed to reduce the multipathing of FM radio signals in areas where the

signals are strongest. The antenna will not provide better reception in weak signal areas.

The diversity antenna system consists of a diversity antenna, diversity antenna module and coaxial leads.

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 signal received from the diversity antenna. It then transmits the

amplified signal to the radio’s diversity antenna input.

The diversity antenna module is located beneath the trim on the passenger side of the rear parcel shelf. The

module is connected to the diversity antenna via one of two coaxial leads, the other lead, located under the

passenger side rocker panel cover, connects the module to the radio’s diversity antenna input extension lead.

Another single wire lead is used to supply the diversity antenna module with 12 V for its operation and the

module is earthed through its case to the vehicle body.

To prevent interference, it is very important that the module and coaxial leads are earthed securely.

The radio 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.

When the vehicle is in motion the radio constantly monitors both antenna inputs and swaps between them in

order to maintain the best possible radio reception.

Figure 12D-4

1.3 HORN BAR STEREO CONTROL OPERATION

There are two major components of the horn bar

stereo control system. These components are as

follows:

1. Right-hand switch assembly –

Located to the right-hand side of the horn bar,

the right-hand switch assembly has three

momentary contact switches that are used to

control VOLUME and MUTE functions of the

stereo.

2. Left-hand switch assembly –

Located to the left-hand side of the horn bar,

the left-hand switch assembly has three

momentary contact switches that are used to

control NEXT UP, NEXT DOWN and MODE

selection.

OPERATION

When a button is pressed on the horn bar control,

the radio decides the function required by

measuring the resistance of the contact pressed.

Each control switch has a unique resistance value,

and this is used by the radio to determine which

command has been issued.

WH12D004

Figure 12D-5

1.4 ROOF MOUNTED REAR REMOTE CONTROL UNIT — CAP RICE

The roof mounted rear remote control unit has two

functions. First the rear remote provides control of

the audio system output in the same manner as the

steering wheel controls. Second, when the

headphones are connected to the output jacks, the

rear remote provides control of audio output

through the headphones by:

• Switch assemblies which control VOLUME,

MUTE, NEXT UP, NEXT DOWN and MODE

selection functions of the stereo.

OPERATION

Switch the audio system on and plug headphones

into one or both jacks adjacent to the child res traint

anchor point on the rear parcel shelf. Press a

button on the roof mounted rem ote control unit and

the radio will decide the function required by

measuring the resistance of the contact pressed.

Each control switch has a unique resistance value,

and this is used by the radio to determine which

command has been issued.

MAST REPLACEMENT

The following procedure is for replacing a damaged

or faulty antenna mast and drive cable assembly.

1. Remove power antenna assembly as

previously described in this Section.

2. Remove chrome plated nut from top end of

mast tube.

3. Extend damaged antenna mast as far as

possible by attaching battery negative via a

jumper lead to antenna mounting bracket and

battery positive to both the antenna red and

white wire terminals.

At end of mast travel, pull out mast and drive

cable from antenna housing.

NOTE: If mast is too badly damaged to extend,

grip tip of mast with a pair of pliers and pull mast

and drive cable ass embly up and out from antenna

housing.

4. If necessary, remove contact spring (metal

sleeve) from old mast and drive cable and

install onto replacement mast and drive cable.

5. Feed end of drive cable down mast tube of

antenna housing with serrated side of drive

cable facing toward the centre of the housing.

Continue to feed drive cable down until it

engages with the drive mechanism.

NOTE: It may be necessary to twist the drive cable

clockwise and anti-clockwise slightly to enable end

of cable to feed through opening at base of mast

tube before it engages the drive mechanism.

6. With the aid of an ass istant to hold the antenna

and mast assembly, connect antenna mounting

bracket via a jumper lead to battery negative.

7. Momentarily connect battery positive to the

antenna red wire and drive mechanism should

start to retract drive cable into antenna

housing.

8. With the drive cable engaged to drive

mechanism, reconnect battery positive to

antenna red wire and allow drive mechanism to

wind in drive cable and mast into mast tube

and housing.

9. At this stage the mast might be fully retracted

into the mast tube and housing. Reconnect

both the red and white wires to battery positive

and allow the mast to extend fully until the

motor stops.

Disconnect white wire from battery positive and

allow mast to fully retract.

10. Install chrome plated nut to top end of mast

tube and tighten securely.

11. Install power antenna assembly as previously

described in this Section. Check antenna m ast

operation.

CHECKING ANTENNA MOTOR OPERATION

If the antenna motor does not correctly respond to

the inputs as specified, ensure that a good earth

connection is being made through the mounting

bracket by measuring the resistance from the

bracket to a good earth point. If more than 1 ohm

replace power antenna assembly. Check that the

forked earth connector is securely attached to the

antenna mounting.

NOTE: If there is significant noise on the AM band

(with radio tuned to weak station outdoors), then

check antenna earth quality. The antenna earth

terminal has a large effect on the screen.

2.9 DIVERSITY ANTENNA

The divers ity antenna is an integral part of the rear

window assembly. The thin conductors that form

the diversity antenna are laid on the inside of the

rear window glass in the same manner as the

heated rear window elements.

A single terminal is located on the ins ide of the r ear

window glass, on the passenger side, to allow

connection of the diversity antenna to the diversity

antenna module, located under the rear parcel

shelf trim.

The diversity antenna module amplifies the radio

signal received by the diversity antenna and

transmits it to the radio/cassette player via coaxial

cable.

NOTE: Due to the internal circuitry of the radio

receiver, if the fender mounted mast antenna is

retracted, faulty or disconnected, the radio m ay not

use the diversity antenna system for radio

reception if the FM signal is weak.

DIVERSITY ANTENNA — TEST

1. Disconnect diversity antenna module connector

from diversity antenna terminal.

2. Using an ohmmeter measure the resistance

from the diversity antenna terminal to the

diversity antenna conductors on the inside of

the rear window glass.

Resistance should be less than 20 ohms from

diversity antenna connector to any point on the

diversity antenna conductors.

NOTE: Care should be taken when measuring

resistance that the diversity antenna conductors

are not damaged by the use of excessive force on

the ohmmeter probe.

3. DIAGNOSIS

This radio problem 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 in order to better understand how to solve problems

when they occur.

2. Many radio problems are caused by basic earthing and short-circuiting problems, which can be quickly found

using the checks included in the ‘Basic Checks’ in this Diagnosis Section.

3. The m ost comm on fault is that of ‘static’ and so an explanation of what it is, what caus es it, and how to fix it is

also included.

4. Diagnostic flow charts are included to help diagnose common complaints.

PRINCIPLES OF OPERATION

Radio Reception

High quality r adio rec eption is obvious ly more dif ficult to achieve in a moving vehic le than f r om a s tationar y location.

Radio systems fitted to vehicles incorporate sophisticated electronics to enhance radio reception by extending the

useable listening range while 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, radio replacement under these circumstances will not affect the radio operating characteristics and has

the potential to create additional owner dissatisfaction. Thus a caref ul, well informed explanation of radio reception

expectations is more lik ely to enhance the owner’s understanding and s atisf action, as well as avoiding unnec essar y

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

character istics to those of light. T hat is , similarly to sunlight, FM radio waves are cut of f by the hor izon. Since m ost

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 such as hills and buildings.

Figure 12D-32

Although FM signals will not bend around corners, they can be reflected by large structures, hills, or buildings, for

example. 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 w ith FM reception and can be characterised by changes in distortion (static)

levels occurring as the vehicle is moving. This is due to the vehicles antenna entering and leaving FM signal

interference areas.

FM signal waves have short wavelength, which also means that 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 will place the antenna in a

region of clear signal.

A vehicle fitted with a two antenna FM diversity system helps reduce multipath interference by ensuring that 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.

Techline

Figure 12D-33

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 radio to these abbreviated

call signal frequencies may be slightly off the correct frequency.

NOTE: FM station call signs are spaced 100 kHz apart in Australia, ie. 93.9, 94.0, 94.1, etc.

AM station call signs are spaced 9 kHz apart, i.e. 999, 1008, 1017, etc.

AM Reception In Vehicles

In contrast to FM s ignals, AM signals will bend around co rner s and s kip along the ground. This is due to AM s ignals

having longer wavelength and lower frequency. The signal can be reflected by the layer of atmosphere known as

the ionosphere. This phenomenon gives AM a longer reception range than FM.

Figure 12D-34

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.

Figure 12D-35

As shown, 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 electr ical equipment in the vehic le 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 that the shield of the antenna cable is effectively earthed at both the radio (to the radio

case) and at the antenna end (to the vehicle body ), to ensure that:

1. Minimal interference is received by the radio.

2. The optimum radio sensitivity is achieved.

BASIC CHECKS

Proper performance of the radio system depends greatly on earthing of the antenna and radio case to the vehicle

body, as it elim inates 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.

With an ohmmeter, the resistances or connection quality can be checked for the major parts of the radio.

When using an ohmmeter 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 m easur e earth resistanc e. This point m ust not have c urrent f lowing

through it during measurement, therefore ensur ing that the ignition is turned O FF . Avoid measur ing us ing the s cr ew

on the door jamb switch. The best place to measure earth resistance is to use one of the self tapping screws

retaining the A-pillar drip rail. Since these screws are sometimes not properly earthed, one of the screws may be

removed to take measurements directly to the body sheet metal.

1. Remove battery earth lead.

NOTE: Failure to disconnec t batter y earth lead may

lead to incorrect resistance measurements due to

stray currents.

2. Disconnect antenna extension lead from

behind passenger side kick trim.

3. Measure resistance from the outer of the

antenna lead to vehicle body (A).

Resistance reading 0.3 ohm max.

4. Measure resistance from outer of the antenna

extension lead to vehicle body (B).

Resistance reading 0.6 ohm max.

Figure 12D-36

5. Check continuity of path from antenna cable

core to antenna mast by measuring resistance

(C).

Resistance reading 0.4 ohm max.

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 antenna lead from antenna lead

extension and measure resistance of extension

lead cable core from radio to antenna lead

connection ends.

Resistance values significantly higher than those

specif ied indicates poor c onnections which m u st be

rectified before proper radio performance will be

obtained.

6. Check for shorts between antenna core and

braid by disconnecting from radio and

meas ur ing the res istanc e between the two. The

meas ured value should indicate an open c ircuit

(very high or infinite resistance).

7. Disconnect antenna extension lead at both

ends and test core for continuity.

COMMON RADIO PROBLEMSCOMMON RADIO PROBLEMS

Static

Static is a buzzing or crack ling noise caused by the radio pick ing up unwanted r adio 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 sugges t, ex ternal inter f er ence c omes from outside the vehicle, and is dif f icult to control,

while internal interference is generated by the vehicle.

It must be emphasised that a radio system in good condition will protect itself from much static. Before trying to

locate and rem ove a sourc e of interf erenc e it m ust f irst be deter m ined that the shielding and earthing 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 that the radio has an internal fault and requires repair.

External Interference

Static which 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 per c eived inter f erenc e level c an be s ignif icantly reduced, in noisy environments , by slightly reducing the

treble on the radio tone controls.

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 som e 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 sometim es fitted with suppressing devic es as par t of their des ign, and f ailur e of thes e suppr es sor s

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 the following figure.

Figure 12D-38

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 earth.

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 occur s . For example, if it occ urs only at speeds above approximately 80 km /h in an automatic trans miss ion

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.

Diagnosing Internal Interference

If a vehicle has an interference problem that only occurs when the engine is turned ON, or som e other repeatable

circumstance, carry out the following procedure:

1. Park 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 on ACC.

2. Reproduce the interference, eg. turn ignition ON.

3. If interference is due to a fan blower motor, etc. and is judged to be objectionable, 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 earthing, etc. If

substituting a new c omponent does not f ix the c ondition, the pr oblem is ver y likely to be in the radio system, and the

resistance checks in this Section should be performed.

4. W histles /squeals that oc cur only when the ignition is ON, are pr obably due to electronic m odules in the vehicle

creating interference when active (power applied). These m odules 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 that any distortion which may be present is not

due to any of the following:

1. Foreign matter such as sand lying on the speaker cone.

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 speaker assembly caused by the angled insertion of the speaker retaining screws. Speaker

problems due to this may be rectified by loosening the screws and retightening, being careful not to distort the

speaker cone again.

CASSETTE PLAYER CARE

To ens ure proper and r eliable operation, the oxides used in tape m anuf acture m us t be cleaned fr om the heads and

capstan drive of the unit, at intervals of no more than 100 hours of operation. Sticky oxide build up on the capstan

can result in tape speed var iation, and ultimately in tape damage. Henc e it is important that user s are advis ed of the

importance of keeping cassette units clean.

Cassette players may be cleaned using a wet head cleaning tape.

then used to start the car, or the car was not locked and a different key used to start the car the BCM will use the

priority key settings for the current key. This may result in the settings changing when the ignition is cycled, and is

part of normal operation.

Suggest to customer that the key used to start the car should be the same key used to unlock the car.

Note 2

If there is an intermittent open circuit or short circuit to body earth in the priority key circuit (Grey) from the BCM to

the radio then the priority key settings may alternate. As the priority key changes, the radio settings will change to

reflect the values stored in each key. This will result in volume, mode, radio station, bass/treble settings to change

for apparently no reason.

This can additionally cause the radio to switch on and off erratically if one priority key sets the radio on and the other

turns it off.

The priority line circuit will need to be investigated for a short or open circuit, refer to Section 12P WIRING

DIAGRAMS in this Supplement.

DIVERSITY ANTENNA FAULT DIAGNOSIS

Before commencing the diagnostic procedure for

the diversity antenna system the following should

be checked:

1. 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 that the diversity antenna

system only affects FM reception.

Such faults are m ore likely to be caused by the

conventional fender mounted mast type

antenna system.

2. Ensure that 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 incr eases in F M

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: W hen the vehicles 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.

1. Remove passenger side cowl panel cover.

Refer to Section 1A1 UNDERBODY in this

Supplement.

Locate the two antenna connectors near the

PCM. The thinner of the two connectors is the

diversity antenna system connector. The one

larger in diam eter is for the conventional fender

mounted mast type antenna.

2. Raise mast antenna to full height.

3. Switch the ignition key to the ACC position.

Switch the radio to the FM band and tune to a

weak station.

NOTE: A weak station can be selec ted by tuning to

different stations and picking one that is of a lower

intensity or contains more ‘noise’ than the others.

4. Lower mast type antenna. Radio reception of

the weak station should now be small enough

so that music can no longer be heard or is

extremely faint.

5. If music can still be heard strongly then repeat

Steps 3 and 4 with weaker stations until music

is virtually non-existent with the mast antenna

lowered.

6. Unplug diversity antenna system connector (2)

from extension to radio.

Unplug mast type antenna (1) from extension

to radio.

WH12D023

Figure 12D-39

7. Plug male diversity antenna lead into female

front antenna extension to radio, making sure

that the pin of the male connector is inserted

fully into the cavity in the fem ale connector and

that the outer conductor of the diversity lead

connector is in contact with shielding of the

radio extension connector.

The diversity antenna system is now connected

to the radio’s conventional antenna input.

8. The radio should now receive the station with

only a little les s s tr ength than the mast antenna

did originally.

If the station cannot be heard, the diversity

antenna may be located in a FM signal

interference area.

To determine if this is the case move the

vehicle a few meters to see if stations

reception improves.

9. If station can be heard clearly then diversity

antenna system is operating correctly.

If the station still can not be heard then the fault

may be in diversity antenna system. Continue

with next step.

10. Test voltage at diversity antenna module to

main wiring harnes s connec tor with k ey in ACC

position. If 12 V then continue with next step.

If 0 V then trace wire back to fault and repair.

11. Remove passenger side quarter window trim

and parcel shelf. Refer to Section 1A8

HEADLINING AND REAR TRIM in this

Supplement.

12. Check connection from diversity antenna

module (1) to rear window connector (2).

Check earth terminal (3) for a good electrical

earth.

WH12D024

Figure 12D-40

13. Disconnect battery earth terminal. Measur e the

resistance from the case of the diversity

antenna module to a good earth point. If

greater than 1 Ω tighten module to parcel shelf

retaining screw and check resistance again.

14. Check diversity antenna f or continuity. Ref er to

DIVERSITY ANTENNA — TEST in this

Section. If antenna continuity is acceptable

then a new diversity antenna m odule should be

tried.
