System Description: Outline
- The BCM incorporates a power saving control function that reduces power consumption according to the vehicle status.
- The 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 and combination meter) that operates with the ignition switch OFF.
Normal mode (wake-up)

- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)
