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.
