SEAT BELT WARNING CHIME : System DescriptionINFOID:0000000001722913
DESCRIPTION
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.
 BCM receives seat belt buckle switch signal from combination meter with CAN communication line.
 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 combination meter with CAN communication line.
 When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled
 Ignition switch OFF→ON
 Seat belt buckle switch (driver side) is ON (driver seat belt not fastened)
WARNING CANCEL CONDITIONS
Cancels the warning if any of the following conditions is fulfilled.
 Ignition switch OFF
 Seat belt buckle switch (driver side) is OFF (driver seat belt fastened)

Unit Description
Combination meter Receives a buzzer output signal from BCM via CAN communication line and sounds the buzzer.
BCMJudges the light warning conditions from the signals provided by various switches and transmits a
buzzer output signal to the combination meter via CAN communication line if necessary.
Combination switch
(Lighting switch)Transmits the lighting switch position signal to BCM.
Front door switch (driver side) Transmits the door switch signal to BCM.

WHEN MECHANICAL KEY IS USED
With the key inserted into the key switch, and the ignition switch in the LOCK or ACC position, when driver's
door is opened, the warning chime will sound.
 BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with
CAN communication line.
 When combination meter receives key warning signal, it sounds the warning chime.
WHEN INTELLIGENT KEY IS CARRIED WITH THE DRIVER
Refer to DLK-16, "Work Flow" (without super lock) or DLK-240, "Work Flow" (with super lock).
