With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.
• The combination meter receives the seat belt buckle switch signal (driver side) from seat belt buckle switch
(driver side) and transmits it to the BCM via CAN communication.
• The BCM receives seat belt buckle switch signal (driver side) from combination meter via CAN communica-
tion.
• The BCM detects seat belt reminder warning based on the received signal and transmits the buzzer output
signal to combination meter via CAN communication.
• The combination meter receives the buzzer output signal from BCM via CAN communication and sounds the
warning buzzer.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled, the warning buzzer will sound.
• Ignition switch ON
• Seat belt buckle switch (driver side) is ON (driver seat belt not fastened)
WARNING CANCEL CONDITIONS
Warning is canceled if any of the following conditions are fulfilled.
