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 t hat reflect off of mountains or buildings.
Noise InspectionINFOID:0000000005931285
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.
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.

DESCRIPTION
CONFIGURATION has three functions as follows:
• READ CONFIGURATION is the function to read (e xtract) vehicle configuration of current BCM.
• WRITE CONFIGURATION-Manual selection is the functi on to select and write vehicle configuration on BCM
manually.
• WRITE CONFIGURATION-Config file is the function to write vehicle configuration with the data extracted
from current BCM.
• For READ CONFIGURATION and WRITE CONFIGURATION -Config file, refer to CONSULT-III Operation
Manual.
• For WRITE CONFIGURATION-Manual selection using the following flow chart, identify the correct model
and configuration list. Confirm and/or change setting val ue for each item according to the configuration list.
Depending on CONSULT-III software version being used, some or all of the write configuration items shown
in the following configuration lists may be display ed. If an item does not appear on the CONSULT-III WRITE
CONFIGURATION-Manual selection screen(s), then it is an auto setting item and it cannot be manually set
or changed.
NOTE:
Confirm vehicle model on IDENTIFICATION PLATE. Refer to GI-43, "
Model Variation".
CAUTION:
• When replacing BCM, you must perform WRITE CONFIGURATION with CONSULT-III.
• Complete the procedure of WRITE CONFIGURATION in order.
• If you set incorrect WRITE CONF IGURATION, incidents will occur.
• Configuration is different for each vehicle model. Confirm conf iguration of each vehicle model.
