COMBINATION METER
The buzzer (1) for the warning chime system is integrated in the
combination meter.
The combination meter sounds the alarm buzzer installed in the
combination meter when receiving the buzzer output signal trans-
mitted 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.
BCM warning function list
NOTE:
Parking brake release warning chime is detected by combination meter.
