INSPECTION PROCEDURE 15: Ever-present noise.

DIAGNOSIS

.

Use the Symptom Chart to diagnose the possible
cause(s) of the noise. Noise is often created by the
following factors:

• Traveling conditions of the vehicle

• Terrain of area travelled through

• Surrounding buildings

• Signal conditions

• Time period

If there are still problems with noise, even after per-
forming inspection procedures 7 to 14, obtain infor-
mation on the factors listed above. Determine
whether the problem occurs on AM or FM, the station
names, frequencies, etc. and contact the radio man-
ufacturer's service center.

INSPECTION PROCEDURE 16: Noise comes out, but neither AM nor FM sounds.

DIAGNOSIS

STEP 1. Check the state of the antenna.
Check that there is no damage or crack in the roof
antenna.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair or replace the roof antenna.

STEP 2. Check to see if inspections are taking
place is an area exposed to special electric
fields.

Q: Are inspections taking place under special electric

field conditions (underground garage, inside a
building, etc).?
YES :

Go to Step 3.

NO :

Go to Step 4.

STEP 3. Relocate and check.
Automatically receive in a good reception area that is
not exposed to special electric fields.

Q: Is reception of the strongest radio frequency

possible within the area?
YES :

The procedure is complete.

NO :

Go to Step 4.

STEP 4. Tune then check.

Q: Did the sensitivity improve after tuning?

YES :

The procedure is complete.

NO :

Go to Step 5.

STEP 5. Check the antenna plug is connected to
the radio and CD player.

Q: Is the antenna plug thoroughly connected to the

radio and CD player?
YES :

Go to Step 6.

NO :

Thoroughly the antenna plug connect to the
radio and CD player.

STEP 6. Check by temporarily replacing the radio
and CD player.

Q: Are operations normal when using another radio

and CD player?
YES :

Either repair or replace the new radio and

CD player.

NO :

Repair or replace the roof antenna.

INSPECTION PROCEDURE 17: Poor reception.

DIAGNOSIS

STEP 1. Check the state of the antenna.
Check that there is no damage or crack in the roof
antenna.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair or replace the roof antenna.

STEP 2. Check to see if inspections are taking
place is an area exposed to special electric
fields.

Q: Are inspections taking place under special electric

field conditions (underneath garage, inside a
building, etc).?
YES :

Go to Step 3.

NO :

Go to Step 4.

STEP 3. Relocate and check.
Automatically receive in a good reception area that is
not exposed to special electric fields.

Q: Is reception of the strongest radio frequency

possible within the area?
YES :

Move the vehicle to check the trouble

symptom.

NO :

Go to Step 4.

STEP 4. Tune then check.

Q: Did the sensitivity improve after tuning?

YES :

The procedure is complete.

NO :

Go to Step 5.

STEP 5. Check with several broadcasting
stations.
NOTE: Multipath noise and fading noise: Because
the frequency of FM waves is extremely high, it is
highly susceptible to effects from geological forma-
tions and buildings. These effects disrupt the broad-
cast signal and obstruct reception in several ways.

.

Multipath noise

•

This describes the echo that occurs when the
broadcast signal is reflected by a large obstruc-
tion and enters the receiver with a slight time
delay relative to the direct signal (repetitious
buzzing).

.

Fading noise

•

This is a buzzing noise that occurs when the
broadcast beam is disrupted by obstructing
objects and the signal strength fluctuates intri-
cately within a narrow range.

Q: Is the abnormality in reception generated only

within a certain range?
YES :

Check that a poor reception is resolved.

NO :

Go to Step 6.

STEP 6. Check the antenna plug connection to
the radio and tape player or radio and CD player.

Q: Is the antenna plug thoroughly connected to the

radio and tape player or radio and CD player?
YES :

Go to Step 7.

NO :

Thoroughly connect the antenna plug and
the radio and tape player or radio and CD
player.

STEP 7. Check by temporarily replacing the radio
and CD player.

Q: Does the other radio and CD player work normally?

YES :

Either repair or replace the radio and CD

player.

NO :

Repair or replace the roof antenna.

INSPECTION PROCEDURE 18: Distortion on AM or on both AM and FM.

DIAGNOSIS

STEP 1. Check the degree in which distortion is
generated.

Q: How much distortion is generated?

Occasional distortion :

Go to Step 2.

Constant distortion :

Go to Step 3.

STEP 2. Check by the transmission antenna.

Q: Is there distortion by the transmission antenna?

YES :

The input from the antenna is too big.

NO :

Go to Step 3.

STEP 3. Check how the speakers are setup.

Q: Are any cords coming in contact with the paper

cones of the speakers?
YES :

Move the cords so that they do not come in

contact with the paper cones of the speaker.
Check that a distortion is resolved.

NO :

Go to Step 4.

STEP 4. Check the speakers.

1. Remove the speakers.
2. Check to see if there is any ripping of the paper

cones or any foreign obstacles in the paper cone.

Q: Are the speakers normal?

YES :

Go to Step 5.

NO :

Repair or replace the speakers.

STEP 5. Check how the speakers are setup.

Q: Check to see if the speakers are setup in a

deformed manner.
YES :

Correct the way the speakers are setup so

they are securely setup.

NO :

Repair or replace the radio and CD player.

INSPECTION PROCEDURE 19: Distortion on FM only.

DIAGNOSIS

STEP 1. Check with another broadcasting
station.

Q: Is there distortion when turning to another

broadcasting station?
YES :

Go to Step 2.

NO :

The signal from that station is too weak.

STEP 2. Relocate the reception area and check.

Q: When relocating the reception area does the

distortion increase or decrease?
YES :

The cause may be multipath noise.

NO :

Repair or replace the radio and CD player.

INSPECTION PROCEDURE 20: Using the auto select function, too few automatic stations are
selected.

DIAGNOSIS

STEP 1. Check the state of the antenna.
Check that there is no damage or crack in the roof
antenna.

Q: Is the check result normal?

YES :

Go to Step 2.

NO :

Repair or replace the roof antenna.

STEP 2. Check the number of radio stations.
