Description

INFOID:0000000006627753

BEFORE REPLACEMENT

When replacing BCM, save or print current vehicle specification with CONSULT-III configuration before
replacement.
NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing BCM.

AFTER REPLACEMENT

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 might occur.
- Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• When replacing BCM, perform the system initialization (NATS).

CONSULT-III Configuration

Perform “READ CONFIGURATION” to save or print current vehicle specification. Refer to

BCS-151, "Descrip-

tion"

.

NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing BCM.

>> GO TO 2.

2.

REPLACE BCM

Replace BCM. Refer to

BCS-161, "Removal and Installation"

.

>> GO TO 3.

3.

WRITING VEHICLE SPECIFICATION

CONSULT-III Configuration

Perform “WRITE CONFIGURATION - Config file” or “WRITE CONFIGURATION - Manual selection” to write
vehicle specification. Refer to

BCS-151, "Work Procedure"

.

>> GO TO 4.

CONFIGURATION (BCM)

Description

INFOID:0000000006627755

Vehicle specification needs to be written with CONSULT-III because it is not written after replacing BCM.
Configuration has three functions as follows.

NOTE:

Manual setting item: Items which need selection by vehicle specifications

Automatic setting item: Items which are written in automatically (Setting can not be changed)

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 might occur.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• Never perform “WRITE CONFIGURATION” when performing operations other than the below.
- Replacing with new BCM
- Changing “SECURITY ALARM SET(SIREN)” of work support from ON to OFF*
NOTE:
*: Perform configuration in “WRITE CONFIGURATION - Manual selection” after performing this work support.

Work Procedure

INFOID:0000000006627756

1.

WRITING MODE SELECTION

CONSULT-III Configuration

Select “CONFIGURATION” of BCM.

When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.

2.

PERFORM “WRITE CONFIGURATION - CONFIG FILE”

CONSULT-III Configuration

Perform “WRITE CONFIGURATION - Config file”.

>> WORK END

3.

PERFORM “WRITE CONFIGURATION - MANUAL SELECTION”

CONSULT-III Configuration

1.

Select "WRITE CONFIGURATION - Manual selection".

2.

Identify the correct model and configuration list. Refer to

BCS-152, "Configuration list"

.

3.

Confirm and/or change setting value for each item.

CAUTION:

Thoroughly read and understand the vehicle specification. Incorrect settings may result in abnor-
mal control of ECU.

4.

Select "SETTING".

CAUTION:

Make sure to select “SETTING” even if the indicated configuration of brand new BCM is same as
the desirable configuration. If not, configuration which is set automatically by selecting vehicle
model can not be memorized.

5.

When "COMMAND FINISHED", select "END".

Function

Description

READ CONFIGURATION

• Reads the vehicle configuration of current BCM.
• Saves the read vehicle configuration.

WRITE CONFIGURATION - Manual selection

Writes the vehicle configuration with manual selection.

WRITE CONFIGURATION - Config file

Writes the vehicle configuration with saved data.

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM

Description

INFOID:0000000006627758

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication Signal Chart. Refer to

LAN-31, "CAN COMMUNICATION SYSTEM : CAN Communica-

tion Signal Chart"
