ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT

Description

INFOID:0000000007228851

BEFORE REPLACEMENT

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

AFTER REPLACEMENT

CAUTION:

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

CONFIGURATION (BCM)

CONFIGURATION (BCM)

Description

INFOID:0000000007228853

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 can not be changed)

For some models and specifications, the automatic setting item may not be displayed.

CAUTION:

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

Work Procedure

INFOID:0000000007228854

WRITING MODE SELECTION

CONSULT Configuration

Select “CONFIGURATION” of BCM.

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

PERFORM “WRITE CONFIGURATION - CONFIG FILE”

CONSULT Configuration

Perform “WRITE CONFIGURATION - Config file”.

>> WORK END

PERFORM “WRITE CONFIGURATION - MANUAL SELECTION”

CONSULT Configuration

Select "WRITE CONFIGURATION - Manual selection".

Identify the correct model and configuration list. Refer to

BCS-65, "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 “SETTING”. Refer to

BCS-65, "Configuration list"

for written items and

setting value.

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.

When "COMMAND FINISHED", select "END".

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM

Description

INFOID:0000000006942453

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.
