NOISE OCCURS
INSPECTION PROCEDURE
1 CHECK OF SPEAKER INSTALLATION
(a) Check the speaker installation condition.
(1) Check that each speaker is securely installed.
Standard: Malfunction disappears.
HINT:
The radio is equipped with the noise prevention system that works against only the excessively large noise,
thereby excessively large noise do not occur in the radio. If large noise occurs, check whether or not the earth
on the antenna installation part and the proper noise±prevention equipment are all installed, and whether
or not the improper wiring is held.
Condition in which noise occursNoise type
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Alternator noise
Noise occurs during the A/C or the heater operation.Blower motor noise
Rapid acceleration during the drive on the unpaved road or after the IG
switch is turned ON makes noise.Fuel pump noise
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes noise.Horn noise
Stopping the engine erases the small noise that has been heard.Ignition noise
Noise occurs in turn with the blink of the turn signal flash.Flasher noise
Noise occurs during the window washer operation.Washer noise
Noise occurs during the engine running, and it continues to occur after the
engine is stopped.Water temperature sensor noise
Noise occurs during the wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity on the vehicle
HINT:

Identify the condition under which the noise occurs, and check the noise filter on the related part.

Make sure first that there is no noise from outside. Failing to do so makes the noise occurrence source
detection impossible and leads to misunderstanding.

The noise should be removed in descending order of loudness.

1.CHECK FUEL PRESSURE
(a)Discharge the pressure in the fuel system and take pre-
cautions for possible fuel spillage.(See page 11±15)
(b) Check that the battery voltage is above 12 V.
(c) Disconnect the negative (±) battery cable.
(d) Pull out the connecter from a new fuel tube.
HINT:
Part No. 23901±0H040
(e) Remove the fuel pipe clamp No.1 from the fuel tube con- nector.
(f) Disconnect the fuel tube connector from the fuel pipe while pinching part A with fingers as shown in the illustra-
tion.
CAUTION:

Do not disconnect the fuel tube connector (quick
type) until after you have discharged the fuel system
pressure and taken appropriate steps to prevent fuel
spillage.

There may be remained pressure in the fuel lines after
discharging the pressure.
Take precautions to prevent fuel from spraying on
you or your clothing or inside the engine compart-
ment.
