Trouble Diagnosis
INFOID:0000000005395317
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 then determine the cause.
NOTE:
The majority of the audio malfunctions are the result of outside causes (damaged CD, electromagnetic inter-
ference, etc.). Check the sympto ms below to diagnose the malfunction.

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 sent directly from the broadcast station arriving at the antenna at a different time from the waves t hat reflect off of mountains or buildings.
Noise InspectionINFOID:0000000005395318
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.
TYPE OF NOISE AND POSSIBLE CAUSE
No sound can be heard from one or several speakers. • Open or short in audio signal circuit between audio unit and front
speaker. Refer to AV- 2 4 , "
