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: Is there more noise on the customers radio?
YES: Check all power and ground connections. If all connections are in
good condition, consult the radio manufacturers service center.
NO: The observed noise is normal.
INSPECTION PROCEDURE 13: Noise is Detected with Engine Running. DIAGNOSIS
CAUTION:
Never connect a noise filter to the high tension
cable (spark plug wire). Spark plug wires
incorporate resistors which have the effect of
suppressing noise. If a spark plug wire is found
to be causing noise, it must be replaced. Confirm that the noise is not from an external
source. Noise prevention should be performed by
suppressing strong sources of noise first.
NOTE: Voltage surges can be induced in the electrical system by
the collapse of a field (i.e. When power is removed from the
coil in an A/C compressor clutch). This induced voltage
surge will radiate a Radio Frequency (RF) signal that is
picked up by the audio unit. In the case of the compressor
clutch a "pop" will be heard through the speakers. The
capacitor, installed on this vehicle, will store the excess
voltage and prevent the production of RF noise. This is
because the capacitor will charge and discharge as the
voltage fluctuates. This has the effect of "attracting" noise
and bleeding it to ground without interfering with the
normal flow of current through the system.

YES: The original CD is defective. The CD player should sound
normally.
NO: Go to Step 2.
STEP 2. Check power supply to the CD player when the ignition switch is

Q: Is the radio and CD
player ener
gized when the i
gnition switch is turned
to the "ACC" or "ON" position?
YES: Replace the audio. The CD player should sound normally.
NO: Check the memory backup power supply circuit. Refer to
INSPECTION PROCEDURE 1
.
INSPECTION PROCEDURE 25: CD Sound Skips. DIAGNOSIS
STEP 1. Check the state in which the sound on the CD jumps.
Q: Does the sound jump when the car is parked?
YES: Go to Step 2.
NO: Go to Step 4 .
STEP 2. Check the surface of the CD.
Q: Are there any scratches or soiling on the CD?
YES: The CD is defective if there are any scratches. Clean the CD surface
if it is dirty. Check that a CD sound skip is resolved.
NO: Go to Step 3.
STEP 3. Check when replacing with a CD that can be played normally
without any scratches or soiling.
Q: Does the CD play normally when replaced with a CD that is not
scratched or dirty and can play normally?
YES: Defective CD used. Check that a CD sound ski
p is
resolved.

NO: Go to Step 4.
STEP 4. Check by tapping the radio and CD player.
Q: Does the sound jump when tapping the radio and CD player?
YES: Securely mount the audio. Check that a CD sound skip is resolved.
NO: Either replace the audio system or take the following measures if a
servicing shop is nearby.
1. Investigate in detail the conditions when the sound jumps while
driving the car.
2. Describe these conditions to the service shop for consultation.
3. Either replace the audio according to the instructions of the service
shop.
Check that a CD sound skip is resolved.
INSPECTION PROCEDURE 26: Sound Quality is Poor. DIAGNOSIS Check to see that the CD can be played normally and that it is free of any
scratches or soiling.
Replace with better sound quality CD.
Q: Is the sound quality better replacing the CD with a clean CD without any
scratches that can be played?
YES: The CD is defective. The sound quality should return to normal.
NO: Replace the audio. The sound quality should return to normal. INSPECTION PROCEDURE 27: CD can not be Ejected. DIAGNOSIS
NOTE: Check by using a known-good CD which is free from
scratches, dirt or any other abnormality.

Check the power of ignition switch "ACC"
.
Q: Does the radio and CD player power turn ON when the ignition switch is in
the "ACC" or "ON" position?
YES: Either replace the audio. Check that a CD can be ejected normally.
NO: Check the memory backup power supply circuit. Refer to INSPECTION
PROCEDURE 1
.
