- CAN transmission is stopped to other units
- Each control with BCM is operating low power consumption mode
Normal mode (wake-up)
- CAN communication is normally performed
- Each control with BCM is operating normally
Low power consumption mode activation
- BCM receives the sleep-ready signal from each unit via CAN communication.
- BCM transmits the sleep wake up signal (sleep) to each unit when receive the sleep-ready signal from each unit.
- Each unit stops the transmission of CAN communication with the sleep wake up signal (sleep).
- BCM perform the low power consumption control when fulfilled with all sleep conditions.
