NOTE:
●
This is noise resulting from variations in field strength, such as fading noise and multi-path noise, or exter-
nal 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 which reflect off of mountains or buildings.
FOR CD ONLY
Noise Inspection
EKS009J9
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 rotation, ignition switch turned to each position, and oper-
ation 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.
