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.

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC U0019: Bus off (CAN-B)

M15410800348USA0000010000

If there is any problem in the CAN bus lines, an
incorrect  diagnostic  trouble  code  may  be  set.
Prior to this diagnosis, always diagnose the CAN
bus lines.

Before  replacing  the  radio  and  CD  player  or  CD
changer, be sure to check that the power supply

circuit, ground circuit, and communication circuit
are normal.

TROUBLE JUDGMENT
When  the  radio  and  CD  player  or  CD  changer  is
returned from the bus off state, or when the bus error
is indicated to the radio and CD player or CD changer
state, the DTC U0019 (CAN-B) is set.
