< FUNCTION DIAGNOSIS >[BCM]
POWER CONSUMPTION CONTROL SYSTEM
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.
