• The majority of the audio malfunctions are the result of outside causes (damaged CD, electromagnetic inter-
ference, etc.). Check the symptom s below to diagnose the malfunction.
• 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 oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.
• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun- tains or buildings blocking the signal.
• Multi-path noise: This noise results from the waves s ent directly from the broadcast station arriving at the
antenna at a different time from the waves that reflect off of mountains or buildings.
Noise Inspection INFOID:0000000004306967
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.
