END ON-BOARD DIAGNOSIS
Turn OFF ignition switch.
Noise InspectionINFOID:0000000005931317
The vehicle itself can be a source of noise if noise
prevention parts or electrical equipment is malfunctioning.
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.

Occurrence condition Possible cause
Occurs only when engine is ON. A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed.
Ignition components
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. Generator
Noise only occurs when various
electrical components are oper-
ating. A cracking or snapping sound occurs with the op-
eration 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. • Rear defogger coil malfunction
• Open circuit in printed heater
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 improper part installation
• Wiring connections or a short circuit
