RELATED TO HANDS-FREE PHONE

• Before performing diagnosis, confirm that the cellular phone being used by the customer is compatible with

the vehicle.

• It is possible that a malfunction is occurring due to a version change of the phone even though the phone is

a compatible type. This can be confirmed by changing the cellular phone to another compatible type, and
check that it operates normally. It is important to determine whether the cause of the malfunction is the vehi-
cle or the cellular phone.

Check Compatibility

1.

Make sure the customer

s Bluetooth

®

 related concern is understood.

2.

Verify the customer

s concern.

NOTE:
The customer

s phone may be required, depending upon their concern.

3.

Write down the customer

s phone brand, model and service provider.

NOTE:
It is necessary to know the service provider. On occasion, a given phone may be on the approved list with
one provider, but may not be on the approved list with other providers.

Noise is mixed with audio.

Noise comes out from all speakers.

Malfunction in audio unit.
Refer to 

AV-15, "On Board Diagnosis Func-

tion"

.

Noise comes out only from a certain speak-
er (front tweeter LH, front tweeter RH, front 
door speaker LH, front door speaker RH, 
rear door speaker LH, rear door speaker 
RH).

• Poor connector connection of speaker.

lash and looseness).
Refer to:

-

AV-55, "Removal and Installation"

AV-57, "Removal and Installation"

 (rear 

door speaker).

• Malfunction in audio unit.

Refer to 

AV-15, "On Board Diagnosis 

Function"

.

Noise is mixed with radio only (when the ve-
hicle hits a bump or while driving over bad 
roads)

Poor connector connection of antenna or 
antenna feeder.
Refer to 

AV-12, "Rod Antenna, Antenna 

Amp., Satellite Antenna and Antenna Feed-
er"

.

No radio reception or poor reception.

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

poor reception is caused even after mov-
ing to a service area with good reception 
(e.g. a place with clear view and no ob-
stacles generating external noises).

• Antenna amp. ON signal circuit malfunc-

tion.
Refer to 

AV-20, "Reference Value"

.

• Poor connector connection of antenna or 

antenna feeder.
Refer to 

AV-12, "Rod Antenna, Antenna 

Amp., Satellite Antenna and Antenna 
Feeder"

.

Buzz/rattle sound from speaker

The majority of buzz/rattle sounds are not 
indicative of an issue with the speaker, usu-
ally something nearby the speaker is caus-
ing the buzz/rattle.

Refer to "SQUEAK AND RATTLE TROU-
BLE DIAGNOSIS" in the appropriate interi-
or trim section.

Description

RELATED TO NOISE

The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,
etc.).
The following noise results 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 the waves sent directly from the broadcast station arriving at the

antenna at a different time from the waves which reflect off mountains or buildings.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.
NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

Type of Noise and Possible Cause

RELATED TO HANDS-FREE PHONE

Occurrence condition

Possible cause

Occurs only when engine is ON.

A continuous growling noise occurs. The speed of 
the noise varies with changes in the engine speed.

• Ignition components

The occurrence of the noise is linked with the operation of the fuel pump.

• Fuel pump condenser

Noise only occurs when various 
electrical components are oper-
ating.

A cracking or snapping sound occurs with the op-
eration of various switches.

• Relay malfunction, audio unit malfunction

The noise occurs when various motors are operat-
ing.

• Motor case ground
• Motor

The noise occurs constantly, not just under certain conditions.

• Rear defogger coil malfunction
• Open circuit in printed heater
• Poor ground of antenna feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially when 
it is vibrating excessively.

• Ground wire of body parts
• Ground due to improper part installation
• Wiring connections or a short circuit

Symptom

Cause and Counter measure

Does not recognize cellular phone connection (No connection is 
displayed on the display at the guide).

Some Bluetooth

®

 enabled cellular phones may not be recognized 

by the in-vehicle phone module.
Refer to “RELATED TO HANDS-FREE PHONE (Check Compati-
bility)” in 

AV-48, "Symptom Table"

.

Cannot use hands-free phone.

Customer will not be able to use a hands-free phone under the fol-
lowing conditions:
• The vehicle is outside of the telephone service area.
• The vehicle is in an area where it is difficult to receive radio 

waves; such as in a tunnel, in an underground parking garage, 
near a tall building or in a mountainous area.

• The cellular phone is locked to prevent it from being dialed.
NOTE:

While a cellular phone is connected through the Bluetooth

®

 wire-

less connection, the battery power of the cellular phone may dis-

charge quicker than usual. The Bluetooth

®

 Hands-Free Phone 

System cannot charge cellular phones.

AV-52

< SYMPTOM DIAGNOSIS >

[AUDIO SYSTEM]

NORMAL OPERATING CONDITION

The other party

s voice cannot be heard by hands-free phone.

When the radio wave condition is not ideal or ambient sound is too 
loud, it may be difficult to hear the other person

s voice during a 

call.

Poor sound quality.

Do not place the cellular phone in an area surrounded by metal or 
far away from the in-vehicle phone module to prevent tone quality 
degradation and wireless connection disruption.
