Abnormal noise occurs

INSPECTION PROCEDURE

1

Check speaker installation

Check if each speaker is securely installed.
OK:

Each speaker is securely installed.

HINT:
The radio is equipped with a noise prevention system that blocks only excessively loud noise. If loud noise
occurs, check that all wiring is proper and that the antenna installation part ground and noise–prevention
equipment are installed.

Conditions under which noise occurs

Noise type

Noise increases when the accelerator pedal is depressed, but stops when

the engine is stopped.

Generator noise

Noise occurs during A/C or heater operation.

Blower motor noise

Noise occurs when the vehicle accelerates rapidly on an unpaved road or

after the ignition switch is turned on.

Fuel pump noise

Noise occurs when the horn switch is pressed and released or when pressed

and held.

Horn noise

Quiet noise is occurs while the engine is running, but stops when the engine

is stopped.

Ignition noise

Noise occurs synchronously with the blink of the turn signal.

Flasher noise

Noise occurs during window washer operation.

Washer noise

Noise occurs while the engine is running, and continues even after the engine

is stopped.

Water temperature sensor noise

Noise occurs during wiper operation.

Wiper noise

Noise occurs when the brake pedal is depressed.

Stop light switch noise

Others.

Static electricity stored on the vehicle

HINT:

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

First ensure that the noise is not coming from outside. Failure to do so makes noise source detection
difficult and may lead to a misdiagnosis.

Noise should be removed in descending order of loudness.

NG

Install it properly.

OK

Identification of noise source (See page
