mounted
.
Q: Is the antenna in good condition and is it properly mounted?
YES: Consult the radio manufacturer's service center.
NO: Either repair or replace the antenna assembly. Check to see that the
noise is gone.
INSPECTION PROCEDURE 12: Excessive Noise on AM and FM. DIAGNOSIS Radio reception can be affected by Radio Frequency (RF) emissions from a variety
of sources. The disturbance is even greater if the station is weak or poorly tuned.
FM reception is not as sensitive to disturbances as AM. AM reception is sensitive to
electrical disturbances such as power lines, lightening and other types of similar
electrical phenomena.
STEP 1. Check if the customer heard the noise under any of the following
conditions.
A motorcycle was passing. Lighting was flashing. Passed beneath a power line. Passed beneath a telephone line. Passed by a signal generator. Passed by any other sources of electrical noise. Passed under a bridge or through a tunnel.
Q: Did the noise occur during any of the circumstances listed above?
YES: The observed noise is normal.
NO: Go to Step 2.
STEP 2. Compare the customers radio to another identical model.
Operate the radio in a vehicle with a known good audio system of the same
t
ype as the customer's.

Q: Are radio and CD player connector C-105 or radio, CD player and CD
changer connector C-105, C-110, C-113 and amplifier connector C-11, C-
12 in good condition?
YES: Go to Step 4.
NO: Repair or replace the damaged component(s). Check that there is no
noise.
STEP 4. Check that noise appears when the radio switch is turned on
while the vehicle is sto
pp
ed and the radio is ta
pp
ed while tuned awa
y from
a station.
Q: Does noise appear when the radio switch is turned on while the vehicle
is stopped and the radio is tapped while tuned away from a station?
YES: Go to Step 5.
NO: It may be static electricity noise.
STEP 5. Verify that the radio is correctly grounded.
The radio is connected to the ground with an assembling screw.
Q: Is the radio correctly grounded?
YES: Go to Step 6.
NO: Tighten the screw securely. Check that there is no noise.
STEP 6. Check by replacing radio and CD player.
NOTE: Body static electricity from the shock absorber rubber
bushings used to prevent vibration, tires, etc. occurs
because of separation from the ground, causing a
buzzing noise. Since no measures can be taken to
discharge the static electricity of the vehicle body.
Check that there is no noise.

STEP 6. Check by replacing radio and CD player.
Q: Do the other radio and CD player work normally?
YES: Either repair or replace the original radio and CD player. Check that
there is no noise.
NO: Either repair or replace the antenna assembly. Check that there is no
noise.
INSPECTION PROCEDURE 16: Constant 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 traveled through Surrounding buildings Signal conditions Time period
If there are still problems with noise, even after performing inspection procedures 8
to 15, obtain information on the factors listed above. Determine whether the
problem occurs on AM or FM, the station names, frequencies, etc. and contact the
radio manufacturer's service center.
INSPECTION PROCEDURE 17: No Reception (AM). DIAGNOSIS
STEP 1. Check the state of the antenna.
