Signal Path

For internal 

• BCM judges whether or not warning the driver is required, according to push switch signal from push-button ignition switch, door switch signal from front door switch (driver side), and ID verification result.
• BCM, when it judges that warning to the driver is required, transmits buzzer output signal to combination meter via CAN communication.
• When combination meter receives buzzer output signal, warning buzzer operates.

For external 

• BCM judges whether or not warning to the driver is required, according to door switch signal from front door switch (driver side) while OFF position warning (for internal) is operated.
• When BCM judges that warning the driver is required, Intelligent Key warning buzzer operates.
