ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Description
INFOID:0000000001451449
When replacing BCM, save or print current vehicle specification with CONSULT-III configuration before
replacement.
Configuration has three functions as follows
• READ CONFIGURATION is the function to read (extract) vehicle configuration of current BCM.
WRITE CONFIGURATION - Manual selection is the function 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.
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 CONFIGURATION, incidents will occur.
Configuration is different for each vehicle model. Confirm configuration of each vehicle model.

3. PERFORM “WRITE CONFIGURATION - MANUAL SELECTION”
For “WRITE CONFIGURATION - Manual selection”, using the following flow chart, identify the correct model
and configuration list.
Confirm and/or change setting value 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 displayed. If an item does not display on the CONSULT-III “WRITE

BODY CONTROL SYSTEM
System DescriptionINFOID:0000000001451453
OUTLINE
BCM (Body Control Module) controls the various electrical components. It inputs the information required to
the control from CAN communication and the signal received from each switch and sensor.
BCM has combination switch reading function for reading the operation status of combination switches (light,
turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power consump-
tion control function that reduces the power consumption with the ignition switch OFF.
BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT-III and various set-
tings.

BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the
status of each switch.
BCM is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch status.
