INSPECTION AND ADJUSTMENT
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)
CAUTION:
 When replacing BCM, you must perform “WRITE CONFIGURATION” with CONSULT-III.
 Complete the procedure of “WRITE CONFIGURATION” in order.
 If you set incorrect “WRITE CONFIGURATION”, incidents might occur.
 Configuration is different for each vehicle model. Confirm configuration of each vehicle model.
 Never perform “WRITE CONFIGURATION” except for new BCM.

BODY CONTROL SYSTEM
System DescriptionINFOID:0000000003809584
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 saving con-
trol function that reduces the power consumption with the ignition switch OFF.
 BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT-III 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 is a combination of 5 output terminals (OUTPUT 1 - 5) and 5 input terminals (INPUT 1 - 5). It reads a
maximum of 20 switch status.

COMBINATION SWITCH READING FUNCTION
Description
 BCM reads the status of the combination switch at 10 ms interval normally.
NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption mode.
 BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5 → 4 → 3 → 2 → 1.
- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of
the transistor on OUTPUT 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”.
Example 1: When a switch (TURN RH switch) is turned ON

< FUNCTION DIAGNOSIS >
COMBINATION SWITCH READING SYSTEM
 The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON.
 BCM detects the combination switch status signal “1E” when the signal of OUTPUT 5 is input to INPUT 1.
 BCM judges that the TURN RH switch is ON when the signal “1E” is detected.
Example 2: When some switches (turn RH switch, front wiper LO switch) are turned ON
 The circuits between INPUT 1 and OUTPUT 5 and between INPUT 1 and OUTPUT 3 are formed when the
TURN RH switch and FR WIPER LOW switch are turned ON.
 BCM detects the combination switch status signal “1CE” when the signals of OUTPUT 3 and OUTPUT 5 are
input to INPUT 1.
 BCM judges that the TURN RH switch and FR WIPER LOW switch are ON when the signal “1CE” 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.

POWER CONSUMPTION CONTROL SYSTEM

System DescriptionINFOID:0000000003809592
OUTLINE
 BCM incorporates a power saving control function that reduces the power consumption according to the
vehicle status.
 BCM switches the status (control mode) by itself with the power saving control function. It performs the sleep
request to each unit (IPDM E/R, combination meter, driver seat control unit and automatic back door control
unit) that operates with the ignition switch OFF.
Normal mode (wake-up)- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
 The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
 BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
 BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful-
filled.
 Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com-
munication sleep mode.
 BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
