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

A/C AND AV SWITCH SYSTEM
Refer to Owner′s Manual for A/C and AV switch operating instructions.
Using the A/C and AV switch at the center of the instrument panel, the controls of the following systems are
centralized:

Integrated display system (Drive computer, setting screen, etc.)

Auto A/C system

Audio system
PRECAUTION OF LCD MONITOR

In order to use LED for backlight of a display, by interior temperature, brightness may change. In low tem-
perature, the refreshing rate of the picture also becomes low because of the low response of the LCD
monitor. When the interior becomes warm, however, the LCD recovers the normal display.

Backlight sometimes flickers or darkens according to the wearing out of LCD and the number of times
switched ON and OFF. In this case, display unit should be replaced. (Exchange only of backlight is impos-
sible.)
POWER SUPPLY AND GROUND
Power is supplied at all times

through 15A fuse (No. 32, located in fuse and fusible link box)

to audio unit terminal 6

to display unit terminal 1 and

to A/C and AV switch terminal 1.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 35

to audio unit terminal 10

to display unit terminal 2 and

to A/C and AV switch terminal 2.
When ignition switch is in ON or START position, power is supplied

through 10A fuse [No. 12, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22 and

to display unit terminal 3.
Ground is supplied

to unified meter and A/C amp. terminals 29, 30

to display unit terminals 6 and 15 and

to A/C and AV switch terminal 5

through body grounds M35, M45 and M85.
Ground is supplied through the case of the audio unit.

Then BCM sends warning signal to display unit warning indications on the screen.
AV COMMUNICATION LINE
Display unit is controlled by the following unit with AV communication line.

A/C and AV switch
CAN Communication System DescriptionAKS007Z5
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
