Noise InspectionAKS005TC
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
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
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 condenser
A whistling noise occurs while the engine speed is
high. A booming noise occurs while the engine is run-
ning and the lighting switch is ON.

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

Fuel pump condenser
Noise only occurs
when various elec-
trical components
are operating. A cracking or snapping sound occurs with the opera-
tion of various switches.

Relay malfunction, radio malfunction
The noise occurs when various motors are operating.

Motor case ground

Motor
The noise occurs constantly, not just under certain conditions.

Rear window defogger coil malfunction

Open circuit in printed heater

Poor ground of antenna amplifier or antenna feeder
line

Mirror type film is attached on the rear window glass

After-market TV antenna and/or electrical accessories
such as radio are attached on the rear window glass.
A cracking or snapping sound occurs while the vehicle is being driven,
especially when it is vibrating excessively.

Poor ground of audio parts

Poor ground due to incorrect installation of parts

Poor wiring connections or a short circuit

DRIVE COMPUTER
Refer to Owner′s Manual for drive computer operating instructions.
TRIP Switch
When “TRIP” switch is pressed, display TRIP screen. As TRIP infor-
mation, it indicates journey time (TIME), trip odometer (DIST), aver-
age vehicle speed (AVG).
Pressing “TRIP” switch once cycles display from TRIP 1 →TRIP
2 → Display OFF →TRIP 1.
“TIME”

Journey time indication is performed by reset or battery connec-
tion.

When pushing “TRIP RESET” or “TRIP” switch more than
approximately 1.5 seconds, journey time will be reset.

If journey time is reset, journey distance and average speed will
be reset at the same time.
“DIST”

Trip odometer indication is performed by vehicle speed signal.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, driving distance will
be reset.

If trip odometer is reset, journey time and average speed will be reset at the same time.
“AVG”

Average speed indication is performed by running distance and running time.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “TRIP” switch more than approximately 1.5 seconds, average speed will
be reset.

After reset operation, the displays shows “ ” for 30 seconds.
FUEL ECON Switch
When “FUEL ECON” switch is pressed, display FUEL ECON screen.
As FUEL ECON information, it indicates average fuel consumption
(AVG), distance to empty (DTE).
Pressing “FUEL ECON” switch once cycles display from FUEL
ECON →Display OFF →FUEL ECON.
“AVG” (Average Fuel Consumption)

Average fuel consumption indication is performed by fuel con-
sumption signal and vehicle speed signal after system is reset.

Indication will be renewed every 30 seconds.

When pushing “TRIP RESET” or “FUEL ECON” switch more
than approximately 1.5 seconds, average fuel economy will be
reset.

After reset operation, the display shows “ . ” until the vehicle is driven 500 m (1,600 ft.) or 30 seconds
has passed.
“DTE” (Distance to Empty)

Distance to empty receives via CAN communication and indicates values calculated by meter.
