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.

POWER CONSUMPTION CONTROL SYSTEM
Sleep condition
Wake-up operation
BCM changes from the low power consumption mode to the CAN communication sleep mode when the any
of the BCM wake-up conditions is fulfilled. Only the control with BCM is activated.
BCM transmits the sleep wake up signal (wake up) to each unit when any of the CAN wake-up conditions is
fulfilled. It changes from the low power consumption mode or the CAN communication sleep mode to the
normal mode.
Each unit starts the transmission of CAN communication with the sleep wake up signal. In addition, the com-
bination meter transmits the wake up signal to BCM via CAN communication to report the CAN communica-
tion start.
