INSPECTION AND ADJUSTMENT

CONFIGURATION (BCM) : Description

INFOID:0000000010122333

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

Configuration has three functions as follows:

CAUTION:

• When replacing BCM, you must perform “Select Saved Data List” or "After Replace ECU" with CON-

SULT.

• Complete the procedure of “Select Saved Data List” or "After Replace ECU" in order.

• If you set incorrect “Select Saved Data List” or "After Replace ECU", incidents might occur.

• Configuration is different for each vehicle model. Confirm configuration of each vehicle model.

• Never perform “Select Saved Data List” or "After Replace ECU" except for new BCM.

.

3. 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.

4. Select “Next”.

CAUTION:

Make sure to select “Next”, confirm each setting value and press “OK” even if the indicated con-

figuration of brand new BCM is same as the desirable configuration. If not, configuration which is

set automatically by selecting vehicle model cannot be memorized.

>> GO TO 4.

4.

OPERATION CHECK

Confirm that each function controlled by BCM operates normally.

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000010122338

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.

LAN-37, "CAN COMMUNICATION SYSTEM : CAN Communica-

tion Signal Chart"
