Sleep condition
Wake-up operation
BCM transmits sleep wake up signal (wake up) to each unit when any condition listed below is established,
and then goes into normal mode from low power consumption mode.
Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans-
mits wake up signals to BCM with CAN communication to convey the start of CAN communication.
