Symptom ChartBKS0028V

The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.

CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be
incorrectly mastered by the customer on a computer.

Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact
Disc Standard and may not play.

Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV- 9 7 , "
Unable to Operate System with A/C
and AV Switch" .
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.

Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.

Multi-path noise: This noise results from a time difference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.

INTEGRATED DISPLAY SYSTEMPFP:28090
System DescriptionBKS0021Y
For system operation information, refer to Owner's Manual.
INTEGRATED DISPLAY SYSTEM

The display unit transmits/receives data signals to/from each control unit with CAN communication. It per-
forms an arithmetical operation on fuel information values by using data obtained from the control units,
and then displays the calculated values on the screen.

The display unit receives vehicle speed signals that are transmitted from the unified meter and A/C amp.,
performs an arithmetical operation on drive information values, and then displays the calculated values on
the screen.
Component DescriptionBKS002D1
DISPLAY UNIT

It receives operation signals of audio system and air conditioner
system from A/C and AV switch, and transmits the operation sig-
nal of audio system to the audio unit through the communication
line and transmits the operation signal of air conditioner system
to the unified meter and A/C amp. through CAN communication.

Display signal from audio unit is transmitted to display unit
through the communication line, and then the operating state of
the audio system is displayed in the screen.

Display signal from unified meter and A/C amp. is transmitted to
display unit through the CAN communication, and then the oper-
ating state of the air conditioner system is displayed in the
screen.
A/C AND AV SWITCH

A/C and AV switch, an integrated combination of audio system
and air conditioner system switches, are adopted.

Operation signal of audio system is transmitted to the audio unit
through display unit with the communication line.

Operation signal of air conditioner system is transmitted to uni-
fied meter and A/C amp. through display unit with CAN commu-
nication.
