Trouble DiagnosisNKS003LC
The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and
operation of each piece of electrical equipment, and then determine the cause.
Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV- 8 4 , "
Unable to Operate System with A/C
and AV Switch" (Without navigation system), or AV- 1 3 9 , "Unable to Operate System with A/C and AV
Switch" (With navigation system).
Refer to "SERVICE BULLETIN ITB04-055" for the diagnosis of satellite radio.
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 a time difference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.
