COMBINATION METER
The combination meter sounds the alarm buzzer install ed in the combination meter when receiving the buzzer
output signal transmitted from each unit.
BCM
BCM receives signals from various units and transmits a buzzer output signal to the combination meter via
CAN communication if it judges that the warning buzzer should be activated.
