Symptom ChartBKS0020Q

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- 5 8 , "
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.

communication line, and it controls the audio system.

Operation signal from rear audio control switch is transmitted to audio unit through A/C and AV switch and
display control unit, and it controls the audio system.

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

6-CD auto changer was installed in the glove box.
