TROUBLESHOOTING FOR NOISE

M15410800323USA0000010000

AM/FM RADIO AND CD PLAYER

The noise is generated during the engine run.

Check that no noise of external origin is present.
Because the signal reception becomes poor
indoors, check in the open air. If this check is
neglected, the source of noise cannot be

determined, resulting in a false recognition.
Therefore, be sure to perform this check.

When implementing the noise prevention, start
the prevention from the object causing the
strongest noise.

Check that the audio main body and others are
securely grounded.

DIAGNOSIS

Noise types
( ) indicates the
sound type.

Situation

Cause

Countermeasure

AM, FM:
(Crack,

tapping,

rattle, plash)

｠

When the engine speed
is increased, the scratch
noise becomes faster
and the sound volume
decreases.

｠

When the ignition switch
is turned to ACC, the
noise disappears.

｠

Radiation noise caused
mainly by the spark plug

｠

Noise wraparound

Check or replace the ground
cable ground bolt. (Refer to
Figure 1).

AM, FM:
Wiper motor noise
(hum,

distorted

hum)

Synchronized with the
wiper movement, and also
becomes faster when
wiper movement is sped
up. When the wiper is
stopped, the noise also
stops.

Caused by the sparks
generated by the wiper
motor brush.

Replace the wiper motor.

Noise from other
electrical
equipment

-

The noise may be generated
when

the

electrical

equipment become old.

Repair or replace the
electrical equipment.

Static

electricity

(cracking, popping)

No noise is generated
when the vehicle comes to
a complete stop.

The parts or wiring move for
some reason, and cause the
noise by contacting against
the body metal parts.

Return the parts and wiring
to the normal positions.

Various types of noise are
generated in various parts
of the body.

Caused by the looseness
between the body and the
hood,

liftgate,

bumper,

exhaust pipe and muffler,
suspension, or others.

Securely

tighten

the

mounting bolts of each part.

NOTE:

For trouble symptoms other than the noise,

perform the following troubleshooting procedures.
Refer to P.54B-18.
