DESCRIPTION
Combination Meter:
The combination meter sounds the alarm buzzer installed 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.
Air Bag Diagnosis Sensor Unit:
Air bag diagnosis sensor unit receives signals from front seat belt buckle switch RH, and rear seat belt buckle switches, then transmits a buzzer output signal to the combination meter via CAN communication if it judges that the warning buzzer should be activated.
