TROUBLESHOOTING
There is noise when the engine is running.
Kind of Noise (Parenthe-
sized is how noise
sounds.)SymptomCauseRemedy
AM, FM: Ignition noise
(Popping, snapping,
crackling, buzzing)
Popping sound becomes
faster with the increase
of engine speed.

The noise is lost with
ignition switch turned to
ACC.
Mainly due to the
spark plugs.

Due to noise circula-
tion from elsewhere

Noise from the engineCheck the noise capacitor
and earth cable and
replace if necessary. (See
Fig. 1 and Fig. 2.)
AM, FM: Defogger noise
(1) (Murmuring)Occurs when the defogger
switch is turned to ON and
OFF.Noise produced by spark-
ing when the defogger
switch is turned to ON/
OFF enters the glass
antenna.Check the noise capacitor
and replace if necessary.
(See Fig. 1.)
AM, FM: Defogger noise
(2) (Snapping noise)Occurs when the defogger
switch is turned to ON.Noise produced by current
flowing in the defogger
enters the glass antenna.Check the choke coil and
replace if necessary.
(See Fig. 3.)
AM, FM: Defogger noise
(3) (Scratching, gaggling)Occurs when the defogger
switch is turned to ON with
print heater wire broken.Noise produced by spark-
ing where print heater is
broken enters the glass
antenna.Repair the print heater.
AM, FM: Wiper motor
noise (Humming, wheez-
ing)Sound becomes faster with
the increase of wiper speed
and is lost when the wiper is
stopped.Caused by sparking in
wiper motor brush.Replace the wiper motor.
FM: Mirror motor noise
(Humming, wheezing)Occurs when electric mirror
operates.Caused by sparking in
mirror motor brush.Replace the electric
motor.
Other electrical compo-
nents–Noise is emitted by some
electrical components in
long use.Repair or replace electri-
cal components.
Static electricity (Crack-
ling, crinkling)
Noise is stopped when
the vehicle comes to a
complete stop.

Noise becomes louder
when the clutch is
released.Occurs when parts or
wiring move for some
reason and contact metal
parts of the body.Put parts or wiring into
position.
Various noises are produced
by body parts.Due to electrical detach-
ment of the hood, exhaust
pipe and muffler, suspen-
sion, etc. from the body.Tighten mounting bolts
securely. In many cases,
remedy of one part does
not eliminate the problem
due to incomplete earthing
elsewhere.
Caution
(1) Never let the noise filter contact a high tension cable. The noise filter could break down.
(2) Check that there is no external noise. This check is necessary to prevent misidentification of noise
sources.
(3) Noise prevention should be performed by eliminating noise sources in the descending order of loudness.

NOTE
1. Noise Suppressing Capacitor
The capacitor does not allow the passage of DC current but AC current. It decreases in impedance (resistance
to AC) as the number of waves increases, making the AC flow easier. A noise suppressing capacitor relying
on this property to function is inserted between a noise generating power line and earthing line to suppress
noise by earthing noise components (in AC or pulse signal) to the vehicle body.
2. Noise Filter
The coil allows the passage of DC current and increases in impedance (resistance to AC) as the number of
waves increases. A noise suppressing coil relying on this property to function is inserted somewhere in a noise
generating power line, preventing noise components from flowing or radiating from the line.

DISCHARGING SYSTEM
1. Run the engine at an engine speed of 1,200–1,500 r/min
for approximately 5 minutes with the A/C operating to
return to the oil.
NOTE
Returning the oil will be more effective if it is done while
driving.
2. Stop the engine.
3. Connect the charging hose (blue) to the adaptor valve
1 with its handle turned back all the way (valve closed).
4. Connect the quick joint 2 to the charging hose (blue),
and install the quick joint to the low-pressure service valve.
NOTE
The low-pressure service valve is provided on the suction
pipe.
Caution
(1) To connect the quick joint, press section “A” firmly
against the service valve until a click is heard.
(2) When connecting, run your hand along the hose
while pressing to ensure that there are no bends
in the hose.
5. Place the adaptor valve 1 inside the container and
discharge the refrigerant by opening the handle gradually
so that oil does not gush out.
NOTE
Any oil remaining in the container should be returned
to the A/C system.
PERFORMANCE TEST
1. The vehicle to be tested should be placed in a place
that is not exposed to direct sunlight.
2. The ambient condition should be 16 – 30 °C in temperature
and 60 – 100 % in relative humidity.
3. Open all the doors so that the air condition inside the
passenger compartment may be identical to that of the
outside.
4. With the high-pressure side of the gauge manifold closed,
connect the charging hose (red) to the gauge manifold
high-pressure side. Attach the quick joint for high-pressure
to the charging hose (red) and install it to the high-pressure
service valve on the vehicle side.
NOTE
The high-pressure service valve is found on liquid pipe
