Related to noise
The majority of the audio concerns are the result of outside causes (bad cd, electromagnetic interference, etc.).
The following noise results 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.
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 operation 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.
