System Description: Outline
- BCM incorporates a power saving control function that reduces the power consumption according to the vehicle status.
- BCM Switches the status (control mode) by itself with the power saving control function. It performs the sleep request to each unit (IPDM E/R, combination meter, TCU, Driver Seat Control Unit, pre-crash seat belt Control Unit, CAN Gateway and Steering Force Control Module) that operates with the Ignition Switch OFF.
Normal mode (wake-up)

- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)
- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)
