[WITH INTELLIGENT KEY SYSTEM]

SYSTEM

• 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 wakeup signal. BCM is in CAN com-

munication sleep mode.

• BCM is in the low power consumption mode and performs the low power consumption control when all of the

BCM sleep conditions are fulfilled with CAN sleep condition.

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 are 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

are 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.
