Description
INFOID:0000000006166631
AUDIO SYSTEM
The majority of the audio troubles are the result of outside causes (bad CD, electromagnetic interference,
etc.).
Noise
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.

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 (if equipped)
• 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

be displayed every time on account of the data
processing.
System is not malfunctioning.
Vehicle mark is not positioned cor-
rectly.
Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF.
Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.

mode after the lighting switch is
turned ON.
The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.

hicle is in or behind a building.
Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the instrument pan-
el.

ing the vehicle.
Vehicle location accuracy is low.

Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle.
Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted. If
advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.

always deviated to the same position.)
As a rule, an updated map DVD–ROM will be
released once a year.
