INSPECTION PROCEDURE 19: Distortion on AM and/or FM.

DIAGNOSIS

.

STEP 1. Check the level of distortion.
Q: How much distortion is there?

Occasional distortion : Go to Step 2.
Constant distortion : Go to Step 3.

STEP 2. Check the location of the distortion.
Q: Is there distortion when the vehicle is near the radio 

station?
YES : The antenna is receiving too strong a signal.
NO :  Go to Step 3.

STEP 3. Check the wires at each speaker.
Q: Are the speaker wires contacting the paper speaker 

cone?
YES : Move the speaker wires away from the paper speaker 

cone. The speaker should now be free of distortion.

NO :  Go to Step 4.

STEP 4. Remove the speakers, and check the paper cone 
for foreign material or damage.
Q: Is there foreign material or damage on the paper cone of 

the speaker?

STEP 5. Check for distortion with the speaker installed.
Q: Does a distortion occur?

YES : Install the speaker securely. The speaker should now 

be free of distortion.

NO :  Repair or replace the radio and CD player or radio, 

CD player and CD changer. The speaker should now 
be free of distortion.

INSPECTION PROCEDURE 20: Distortion on FM Only.

.

DIAGNOSIS

STEP 1. Check that the distortion is present when the radio 
is tuned to another station.
Q: Does the distortion persist when the radio is tuned to 

another station?
YES : Go to Step 2.
NO :  The signal from that station is too weak.

STEP 2. Relocate the reception area and check the radio.
Q: When relocating the reception area does the distortion 

increase or decrease?
YES : The cause may be multipath or fading noise. 

Multipath noise is the echo that occurs when the 
broadcast signal is reflected by a large obstruction 
and enters the receiver with a slight time delay 
relative to the direct signal (repetitious buzzing). A 
fading or buzzing noise may occur when the 
broadcast beam is disrupted by obstructing objects 
and the signal strength fluctuates within a narrow 
range.

NO :  Replace the radio and CD player or radio, CD player 

and CD changer. Check that a distortion is resolved.

area?
YES : Go to Step 2.
NO :  Go to Step 3.

STEP 2. Check the distance from the transmission 
antenna.

miles?
YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. The check if there are not that many radio stations 
and when there is no transmission antenna in the vicinity.
Execute automatic selection and check to see that the stron-
gest radio frequency is receivable within the area.
Q: Is reception of the strongest radio frequency possible 

within the area?
YES : There is no action to be taken.
NO :  Go to Step 4.

STEP 4. 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 5.
NO :  Go to Step 6.

STEP 5. 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 : There is no action to be taken.
