Noise Inspection

AKS005F3

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and determine the cause.

NOTE:
The source of the noise can be found easily by listening to the noise while removing the fuses of electrical
components, one by one.

TYPE OF NOISE AND POSSIBLE CAUSE 

Occurrence condition

Check item

Occurs only when engine is ON

A continuous growling noise occurs. The speed of 
the noise varies with changes in the engine speed

Ignition condenser

A whistling noise occurs while the engine speed is 
high. A booming noise occurs while the engine is 
running and the lighting switch is ON

Alternator

The occurrence of the noise is linked with the operation of the fuel pump

Fuel pump condenser

Noise only occurs when various 
electrical components are oper-
ating

A cracking or snapping sound occurs with the 
operation of various switches

Relay malfunction, radio malfunction

The noise occurs when various motors are operat-
ing

Motor case ground

Motor

The noise occurs constantly, not just under certain conditions

Poor ground of antenna amp. or antenna 
feeder line

A cracking or snapping sound occurs while the vehicle is being driven, especially 
when it is vibrating excessively

Ground wire of body parts

Ground due to incorrect installation of parts

Wiring connections or a short circuit
