NORMAL OPERATING CONDITION
DescriptionINFOID:0000000012432976
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- 1 0 8 , "
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.
