(a) A CD player uses a laser pickup to read digital
signals recorded on CDs. By converting the digital
signals to analog, music and other content can be
played.
CAUTION:
Do not look directly at the laser pickup because
the CD player uses an invisible laser beam. Be
sure to operate the player only as instructed.
NOTICE:
•Do not disassemble any part of the CD player.
•Do not apply oil to the CD player.
•Do not insert anything but a CD into the CD
player.

(c) Precautions for use of discs
NOTICE:
•Copy-protected CDs cannot be played.
•CD-Rs and CD-RWs may not be played
depending on the recording conditions or
characteristics of the discs, or due to
damage, dirt, or deterioration caused by
leaving the discs in the cabin for a long time.
•Unfinalized CD-Rs and CD-RWs cannot be
played.
•Keep the discs away from dirt. Be careful not
to damage the discs or leave your
fingerprints on them.
•Hold discs by the outer edge and center hole
with the label side up.
•Leaving the disc exposed halfway out of the
slot for a long time after pressing the disc
eject button may cause deformation of the
disc, making the disc unusable.
•If discs have adhesive tape, stickers, CDR
labels, or any traces of such labels attached,
the discs may not be ejected or player
malfunctions may result.
AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM
•Keep the discs away from direct sunlight.
(Exposure to direct sunlight may cause
deformation of the disc, making the disc
unusable.)
•Do not use odd-shaped CDs because these
may cause player malfunctions.
•Do not use discs whose recording portion is
transparent or translucent because they may
not be inserted, ejected, or played normally.
HINT:
•When it is cold or it is raining, if the windows mist
up, mist and also dew may form in the player. In
such a case, the CD may skip or the CD may
stop in the middle of play . Ventilate or dehumidify
the cabin for a while before using the player.
•The CD may skip if the player experiences strong
vibrations when the vehicle is driven on rough
road or similar uneven surface(s).
(d) Cleaning

3.AVC-LAN DESCRIPTION
(a) What is AVC-LAN?
AV–7
Radio Receiver
(Resistor 60 to 80 Ω)
AVC-LAN
Stereo Component Amplifier
AVC-LAN, an abbreviation for "Audio Visual
Communication Local Area Network", is a united
standard developed by the manufacturers in
affiliation with Toyota Motor Corporation. This
standard pertains to audio and visual sign als as well
as switch and communication signals.
(b) Purpose:
Recently , car audio systems have rapidly developed
and the functions have vastly changed. The
conventional car audio system is being integrated
with multi-media interfaces similar to those in
navigation systems. At the same time, customers
are demanding higher quality from their audio
systems. This is merely an overview of the
standardization background. The specific purposes
are as follows:
(1) To solve sound problems, etc. caused by using
components of different manufacturers through
signal standardization.
(2) To allow each manufacturer to concentrate on
developing products they do best. From this,
reasonably priced products can be produced.
HINT:
•If a short to +B or short to ground is detected
in the AVC-LAN circuit, communication is
interrupted and the audio system will stop
functioning.
I100319E09
AV
AV–8
AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM
•If the audio system has a navigation system
installed, the multi-display unit acts as the
master unit. If the navigation system is not
installed, the audio head unit acts as the
master unit instead. If the radio and
navigation assembly is installed, it is the
master unit.
•The radio receiver contains a resistor that is
necessary to enable communication on the
different AVC-LAN circuits.
•The car audio system with an AVC-LAN
circuit has a diagnostic function.
•Each component has a specified number (3digit) called a physical address. Each function
has a number (2-digit) called a logical
address.
4.COMMUNICATION SYSTEM OUTLINE
(a) Components of the audio system communicate with
each other via the AVC-LAN.
(b) The master component of the AVC-LAN is a radio
receiver with a 60 to 80 Ω resistor. This is essential
for communication.
(c) If a short circuit or open circuit occurs in the AVC-
LAN circuit, communication is interrupted and the
audio system will stop functioning.
5.DIAGNOSTIC FUNCTION OUTLINE
(a) The audio system has a diagnostic function (the
result is indicated on the master unit).
(b) A 3-digit hexadecimal component code (physical
address) is allocated to each component on the
AVC-LAN. Using this code, the component in the
diagnostic function can be displayed.
AV
6."BLUETOOTH" OUTLINE
(a) "Bluetooth" is a trademark owned by Bluetooth SIG.
Inc.
E100921
AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM
(b) "Bluetooth" is a new wireless connection technology
that uses the 2.4 GHz frequency band. This makes
it possible to connect a cellular phone ("Bluetooth"
*1
compatible phone
) to the radio receiver (the
"Bluetooth" system is built in), and use the
handsfree function of the cellular phone, even if it is
in a pocket or bag. As a result, it is not necessary to
use a connector attached directly to the cellular
phone.
*1
: Some versions of "Bluetooth" compatible cellular
phones may not function.
AV–9
Example:
Radio Receiver
(Built-in “Bluetooth” receiver antenna)

HINT:
The communication performance of "Bluetooth"
may vary depending on obstructions or radio wave
conditions between communication devices,
electromagnetic radiation, communication device
sensitivity, or antenna capacity.

(b) Service area
(1) The service areas of AM and FM broadcasts are
vastly different. Sometimes an AM broadcast
can be received very clearly but an FM stereo
cannot. FM stereo has the smallest service area,
and is prone to pick up static and other types of
interference such as noise.
(c) Radio reception problems
HINT:
In addition to static, other problems such as
"phasing", "multipath", and "fade out" exist. These
problems are not caused by electrical noise, but by
the radio signal propagation method itself.
E108734E01
AV
Phasing
E108735E01
Ionosphere
I100011E02
(1) Phasing
AM broadcasts are susceptible to electrical
interference and another kind of interference
called phasing. Occurring only at night, phasing
is the interference created when a vehicle
receives 2 radio wave signals from the same
transmitter. One signal is reflected off the
ionosphere and the other signal is received
directly from the transmitter.
Multipath
Fade Out
AUDIO / VISUAL – AUDIO AND VISUAL SYSTEM
(2) Multipath
Multipath is a type of interference created when
a vehicle receives 2 radio wave signals from the
same transmitter. One signal is reflected off
buildings or mountains and the other signal is
received directly from the transmitter.
I100012E02
(3) Fade out
Fade out is caused by objects (buildings,
mountains, and other such large obstacles) that
deflect away part of a signal, resulting in a
weaker signal when the object is between the
transmitter and vehicle. High frequency radio
waves, such as FM broadcasts, are easily
deflected by obstructions. Low frequency radio
waves, such as AM broadcasts, are much more
I100013E02
difficult to deflect.
(d) Noise problem
Technicians must have a clear understanding about
each customer's noise complaint. Use the following
table to diagnose noise problems.
AV–13
Radio FrequencyNoise Occurrence ConditionPresumable Cause
AMNoise occurs in a specified areaForeign noise
An identical program transmitted from
