Trouble DiagnosisEKS00I4F
NOTE:
The subwoofer (premium system) may be inoperative if the audio unit harness connectors have not been con-
nected in the proper sequence (when the battery remains connected). The proper sequence is to connect M44
and M45 first followed by M43 last. If the subwoofer is inoperative, be sure to check this condition. Refer to AV-
40, "Sound Is Not Heard From Subwoofer (Premium System)" .

The majority of the audio malfunctions are the result of outside causes (damaged 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 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.
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 that reflect off of mountains or buildings.
Noise InspectionEKS00I9T
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.
