BEFORE REPLACEMENT

When replacing BCM, save or print current vehicle specification with CONSULT configuration before replace-
ment.
NOTE:
If “Before Replace ECU” of “Read / Write Configuration” cannot be used, use the “Manual Configuration” after
replacing BCM.

AFTER REPLACEMENT

CAUTION:

When replacing BCM, always perform “Read / Write Configuration” or “Manual Configuration” with
CONSULT. Or not doing so, BCM control function does not operate normally.
• Complete the procedure of “Read / Write Configuration” in order.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• If you set incorrect “Read / Write Configuration” or “Manual Configuration”, incidents might occur.
NOTE:
• When replacing BCM, perform the system initialization (CAN gateway).
• When replacing BCM, perform the system initialization (NATS) (if equipped).
• When replacing BCM, perform the system initialization (TPMS) (if equipped).

CONFIGURATION (BCM)

CONFIGURATION (BCM)

Description

INFOID:0000000010378024

Vehicle specification needs to be written with CONSULT 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 cannot be changed)
For some models and specifications, the automatic setting item may not be displayed.

CAUTION:

When replacing BCM, always perform “Re/programming, Configuration” with CONSULT. Or not doing
so, BCM control function does not operate normally.
• Complete the procedure of “Read / Write Configuration” in order.
• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
• Never perform “Read / Write Configuration” except for new BCM.
• If you set incorrect “Read / Write Configuration”, incidents might occur.

Work Procedure

INFOID:0000000010378025

WRITING MODE SELECTION

CONSULT Configuration

Select “Re/programming, Configuration” of BCM.

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

PERFORM “AFTER REPLACE ECU” OF “READ / WRITE CONFIGURATION”

CONSULT Configuration

Perform “After Replace ECU” of “Read / Write Configuration”.

>> WORK END

PERFORM “MANUAL CONFIGURATION”

CONSULT Configuration

Select “Manual Configuration”.

Identify the correct model and configuration list. Refer to

BCS-117, "Configuration list"

Confirm and/or change setting value for each item.

CAUTION:

Thoroughly read and understand the vehicle specification. ECU control may not operate normally
if the setting is not correct.
NOTE:
If items are not displayed, touch “Next”. Refer to

BCS-117, "Configuration list"

for written items and setting

value.

Touch “Next”.

Touch “OK”.

CAUTION:

Make sure to select “OK” 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
cannot be memorized.

Check that the configuration has been successfully written and touch “End”.

Function

Description

Read / Write Configuration

Before Replace ECU

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

After Replace ECU

Writes the vehicle configuration with saved data.

Manual Configuration

Writes the vehicle configuration with manual selection.

U1000 CAN COMM

DTC Description

INFOID:0000000010378028

DESCRIPTION

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
