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.
