• 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 fo r 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 perfo rms the diagnosis with CONSULT-III and various set-
tings.

OUTLINE
• BCM incorporates a power consumpt
ion 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 and In telligent Key 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 20 ms interval.
Sleep mode activation
• BCM receives the sleep-ready signal (ready) from IPDM E/R, combination meter and Intelligent Key unit via
CAN communication.
• 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 communicati on 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.
