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
1.
WRITING MODE SELECTION
CONSULT Configuration
Select “CONFIGURATION” of BCM.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.

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.
