INSPECTION PROCEDURE 3: Noise Appears at Certain Places when Travelling (AM).

DIAGNOSIS PROCEDURE

Step 1. Check the noise occur when entering or 
near a particular structure (building, tunnel, 
mountain, etc).

Q: Does the noise occur when entering or near a 

particular structure (building, tunnel, mountain, 
etc).?
YES : 

Go to Step 3.

NO : 

Go to Step 2.

Step 2. After taking the following measures to 
prevent the noise, check that no noise appears.
(1) Change to a different station with a stronger wave 

to boost resistance to interference.

(2) Suppress high tones to reduce noise.
(3) Extend antenna completely.

Q: Do the following measures eliminate the noise?

YES : 

The following causes can be considered.

NO : 

Go to Step 4.

Step 3. Ask the owner about the state of the 
noise.
(1) Find out the following information from the owner.
(2) Place where the noise occurs.
(3) Locality conditions (valley, mountain, etc).
(4) Name and frequency of stations affected by noise

Q: Which is the noise, vehicle noise or external 

noise?
Vehicle noise : 

It may not be possible to prevent 

noise if the signal is weak.

External noise : 

In almost all cases, prevention on 

the receiver side is impossible. Weak 
signals especially are susceptible to 
interference. Go to Step 4.

Step 4. Check that there is no noise.

Q: Does noise still exist? 

YES : 

If there is more noise than on radios in other 

vehicles, find out the noise condition and 
the name and frequency of the receiving 
stations from the owner, and consult with 
the radio manufacturer's service centre.

NO : 

Normal.
