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.

The Intelligent Key system is a system that makes it possible to lock and unlock the door locks (door lock/
unlock function) by carrying the Intelligent Key, which operates based on the results of electronic ID verifica-
tion using two-way communications between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
The settings for each function can be changed with the CONSULT-III.
If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
It is possible to perform a diagnosis on the system and register an Intelligent Key with CONSULT-III.
