Only a certain speaker (front right, 
front left, rear right, or rear left, etc.) 
does not output sound.

• Poor connector connection of speaker.
• Sound signal circuit malfunction between audio unit and 

speaker.

• Malfunction in speaker.
• Malfunction in audio unit.

Noise is mixed with audio. 

Noise comes out from all speakers.

Malfunction in audio unit.

Noise comes out only from a certain 
speaker (front right, front left, rear 
right, or rear left, etc.).

• Poor connector connection of speaker.
• Sound signal circuit malfunction between audio unit and 

speaker.

• Malfunction in speaker.
• Poor installation of speaker (e.g. backlash and looseness)
• Malfunction in audio unit.

Noise is mixed with radio only 
(when the car hits a bump or while 
driving over bad roads).

Poor connector connection of antenna or antenna feeder.

Radio is not received or poor re-
ception.

• Other audio sounds are normal.
• Any radio cannot be received or 

poor reception is caused even af-
ter moving to a service area with 
good reception (e.g. a place with 
clear view and no obstacles gen-
erating external noises). 

• Antenna amp. ON signal circuit malfunction.
• Poor connector connection of antenna or antenna feeder.

RELATED TO AUDIO

• 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 malfunctioning.

Check that noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment. Then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incor-

rectly mastered by the customer on a computer.

• Check that 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.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.

NOTE:

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains 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.

Symptoms

Cause and counter measure

Cannot play

Check that the CD was inserted correctly.

Check that the CD is scratched or dirty.

Check that there is condensation inside the player, and if there is, wait until the condensation is 
gone (about 1 hour) before using the player.

The player will play correctly after it returns to the normal temperature if there is a temperature 
increase error. 

Only the music CD files (CD-DA data) will be played if there is a mixture of music CD files (CD-
DA data) and MP3/WMA files on a CD. 

Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played.

Check that the finalization process, such as session close and disc close, is done for the disc.

Check that the CD is protected by copyright.

Poor sound quality

Check that the CD is scratched or dirty.

It takes a relatively long time before 
the music starts playing.

If there are many folder or file levels on the MP3/WMA CD, or if it is a multi session disc, some 
time may be required before the music starts playing.

The songs do not play back in the 
desired order.

The playback order is the order in which the files were written by the software, so the files might 
not play in the desired order.

Poor reception only from a certain 
radio broadcast station.

Check incoming radio wave signal strength of applicable broadcast station.

Buzz/rattle sound from speaker

The majority of rattle sounds are not indicative of an issue with the speaker, usually something 
nearby the speaker is causing the rattle.
