2. IDENTIFICATION OF NOISE SOURCE
(a) Identify the condition under which the noise occurs, and
check the noise filter on the related part.
Condition in which noise occursNoise Source
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Generator
Noise occurs during the A/C or the heater operation.Blower motor
Rapid acceleration while driving on the unpaved road or after the IG switch is
turned ON makes noise.Fuel pump
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes unusual noise.Horn
Stopping the engine erases small noise that has been heard.Ignition
Noise occurs synchronously with the turn signal flash.Flasher
Noise occurs during the window washer operation.Washer
Noise occurs during the engine running, and it continues after the engine
stops.Engine coolant temperature sensor
Noise occurs during the wiper operation.Wiper
Noise occurs when the brake pedal is depressed.Stop light switch
Others.Static electricity stored on the vehicle
(b) Reference:

Make sure first that there is no noise from outside.
Failing to do so makes the noise source detection
difficult and leads to misunderstanding.

The noise should be removed in descending order
of loudness.

Setting the radio untuned makes noise noticeable,
making the recognition of the phenomenon easier.

NOISE OCCURS
INSPECTION PROCEDURE
1 CHECK OF SPEAKER INSTALLATION
(a) Check the speaker installation condition.
(1) Check that each speaker is securely installed.
Standard: Malfunction disappears.
HINT:
The radio is equipped with the noise prevention system that works against only the excessively large noise,
thereby excessively large noise do not occur in the radio. If large noise occurs, check whether or not the earth
on the antenna installation part and the proper noise±prevention equipment are all installed, and whether
or not the improper wiring is held.
Condition in which noise occursNoise type
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Alternator noise
Noise occurs during the A/C or the heater operation.Blower motor noise
Rapid acceleration during the drive on the unpaved road or after the IG
switch is turned ON makes noise.Fuel pump noise
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes noise.Horn noise
Stopping the engine erases the small noise that has been heard.Ignition noise
Noise occurs in turn with the blink of the turn signal flash.Flasher noise
Noise occurs during the window washer operation.Washer noise
Noise occurs during the engine running, and it continues to occur after the
engine is stopped.Water temperature sensor noise
Noise occurs during the wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity on the vehicle
HINT:

Identify the condition under which the noise occurs, and check the noise filter on the related part.

Make sure first that there is no noise from outside. Failing to do so makes the noise occurrence source
detection impossible and leads to misunderstanding.

The noise should be removed in descending order of loudness.

4. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows you to operate the relay, VSV, actuator,
etc. without parts removal. Performing the ACTIVE TEST as the first step of troubleshooting is one way to
shorten the labor time. It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on the tester, perform the ACTIVE TEST.

ONLY WIRELESS CONTROL FUNCTION DOES NOT OPERATE
(PREPARE NEW OR NORMAL TRANSMITTER OF THE SAME
TYPE VEHICLE)
CIRCUIT DESCRIPTION
The door control receiver receives a signal from the transmitter and sends this signal to the integration relay.
Then, the integration relay controls door operation by sending a door LOCK/UNLOCK signal and a luggage
door (back door) unlock signal to each door lock motor.

DOUBLE LOCK FUNCTION DOES NOT OPERATE PROPERLY
CIRCUIT DESCRIPTION
RHD Models w/ Double Lock Only:
All the doors except the back door have the double locking system. This\
system is set and unset by the
integration relay. When the integration relay receives a request signal from the wireless transmitter (See
page 73±1) to set or unset the double locking system, it drives the double lock \
motor built into each door
lock according to the condition of all the double lock position switches, th\
us causing the double locking sys-
tem to be set and unset.
