INSPECTION AND ADJUSTMENT

CONFIGURATION (BCM) : Description

INFOID:0000000007354900

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. 

CONFIGURATION (BCM) : Work Procedure

INFOID:0000000007354901

1.

WRITING MODE SELECTION

CONSULT

Select “Reprogramming, Configuration” of BCM.

When writing saved data>>GO TO 2.

When writing manually>>GO TO 3.

2.

PERFORM “SAVED DATA LIST”

CONSULT

Automatically “Operation Log Selection” window will display if “Before Replace ECU” was performed. Select

applicable file from the “Save Data List” and press “Confirm”.

>> Work End.

3.

PERFORM “AFTER REPLACE ECU” OR “MANUAL CONFIGURATION”

CONSULT

1. Select “After Replace ECU” or “Manual Configuration”.

2. Identify the correct model and configuration list. Refer to 

BCS-5, "CONFIGURATION (BCM) : Configura-

tion List"

.

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 can not be memorized.

5. When "Completed", select "End".

>> GO TO 4.

4.

OPERATION CHECK

Confirm that each function controlled by BCM operates normally.

>> Work End.

Function

Description

"Before Replace ECU"

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

"After Replace ECU"

Writes the vehicle configuration with manual selection.

"Select Saved Data List"

System Description

INFOID:0000000007354902

OUTLINE

• BCM (Body Control Module) controls the various electrical components. It inputs the information required to

the control from CAN communication and the signal received from each switch and sensor. 

• BCM has combination switch reading function for reading the operation status of combination switches (light,

turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-

ponents. It also has the signal transmission function as the passed point of signal and the power consump-

tion control function that reduces the power consumption with the ignition switch OFF.

• BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various set-

tings.

OUTLINE

• BCM reads the status of the combination switch (light, turn signal, wiper and washer) and recognizes the

status of each switch.

• BCM has a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5) and reads

a maximum of 20 switch states.

COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms intervals normally.

NOTE:

BCM reads the status of the combination switch at 60 ms intervals when BCM is controlled at low power

consumption control mode.

• BCM operates as follows and judges the status of the combination switch.

- It operates the transistor on OUTPUT side in the following order: OUTPUT 1 

 2 

 3 

 4 

 5, and outputs

voltage waveform.

- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT

side if any (1 or more) switches are ON.

- It reads this change of the voltage as the status signal of the combination switch.

Operation Example

In the following operation example, the combination of the status signals of the combination switch is replaced

as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.

COMBINATION SWITCH READING SYSTEM

• The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.

• BCM detects the combination switch status signal “5D” when the signal of OUTPUT 4 is input to INPUT 5.

• BCM judges that the TAIL LAMP switch is ON when the signal “5D” is detected.

Example 2: When some switches (TURN RH, TAIL LAMP) are turned ON

• The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 4 and INPUT 5 are formed when the

TURN RH switch and TAIL LAMP switch are turned ON.

• BCM detects the combination switch status signal “5AD” when the signals of OUTPUT 1 and OUTPUT 4 are

input to INPUT 5.

• BCM judges that the TURN RH switch and TAIL LAMP switch are ON when the signal “5AD” is detected.

WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)

BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2, and 3 switches.
