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.

CONFIGURATION : Description

INFOID:0000000001712650

Vehicle specification needs to be written with CONSULT-III because it is not written after replacing BCM.
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.

PERFORM “WRITE CONFIGURATION - CONFIG FILE”

Perform “WRITE CONFIGURATION - Config file” with CONSULT-III.

>> WORK END

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
CONFIGURATION - Manual selection” screen, then it is an auto setting item and it cannot be manually set or
changed.

*: Do not apply MODE1, MODE3 or MODE4

BODY CONTROL SYSTEM

System Description

INFOID:0000000001712652

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.

OUTLINE

• 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.

COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms interval normally.

NOTE:
BCM reads the status of the combination switch at 20 ms interval when BCM is controlled at low power con-
sumption control mode.

• BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5
