AUDIO
• The majority of the audio malfunctions are the result of outside causes (Malfunction CD, electromagnetic
interference, 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 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:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be
incorrectly mastered by the customer on a computer.
• Check if the CDs have the Compact Disc logo. If not , the disc is not mastered to the “red book” Compact
Disc standard and may not play.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources, 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 di fference between the broadcast waves directly from the
station arriving at the antenna and the waves reflected by mountains or buildings.
MALFUNCTION WITH USB
NOTE:
Check that there is no malfunction of USB equi pment main body before performing a diagnosis.
