BCM detects ignition switch turned ON and seat belt buckle switch (driver side) ON. And then transmits buzzer output signal (seat belt warning
chime) to unified meter and A/C amp. with CAN communication.
-
Unified meter and A/C amp. transmits buzzer output signal (seat belt warning chime) to combination meter with communication line.
-
When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
NOTE: When ignition key warning chime, light warning chime, and seat belt warning chime should be performed at the same time, the priorities for
each chime are the following:
1. Seat belt warning chime
2. Light warning chime
3. Ignition key warning chime
