WARNING CHIME
System DescriptionINFOID:0000000001328473
Buzzer for warning chime system is installed in the combination meter.
The buzzer sounds when the combination meter receives buzzer output signal from each unit through uni- fied meter and A/C amp.
POWER SUPPLY AND CIRCUIT
Power is supplied at all times
through 50A fusible link (letter M, located in the fuse and fusible link block)
to BCM terminal 55,
through 15A fuse [No. 22, located in the fuse block (J/B)]
to key switch and ignition knob switch terminal 3 (with Intelligent Key), and
to key switch terminal 2 (without Intelligent Key), and
to BCM terminal 42,
through 10A fuse [No. 38, located in the fuse and fusible link block (with Intelligent Key)]
to key switch and ignition knob switch terminal 1,
through 10A fuse [No. 19, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 21, and
to combination meter terminal 8.
When ignition switch is in ON or START position, power is supplied
through 15A fuse [No. 1, located in the fuse block (J/B)]
to BCM terminal 38,
through 10A fuse [No. 12, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 22,
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 7.
Ground is supplied
to BCM terminals 49 and 52,
to unified meter and A/C amp. terminals 29 and 30, and
to combination meter terminals 5, 6 and 15
through grounds M35, M45 and M85.
IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)
With the key inserted into the key switch, and the igniti on switch in OFF or ACC position, when driver's door is
opened, the ignition key warning chime will sound.
BCM detects key inserted into the key switch, igniti on switch in OFF or ACC position, and front door switch
(driver side) ON. And then transmits buzzer output signal (ignition key warning chime) to unified meter and
A/C amp. with CAN communication.
Unified meter and A/C amp. transmits buzzer output signal (ignition key warning chime) to combination
meter with communication line.
When combination meter receives buzzer output signal (ignition key warning chime), it sounds the buzzer.
IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
When Mechanical Key Is Used
With the key inserted into the ignition switch, and the i gnition switch LOCK or ACC position, when driver's door
is opened, the warning chime will sound.
BCM detects key inserted into the key switch, ignition switch in LOCK or ACC position, and front door switch
(driver side) ON. And then transmits buzzer output signal (ignition key warning chime) to unified meter and
A/C amp. with CAN communication.

WARNING CHIME
Unified meter and A/C amp. transmits buzzer output signal (ignition key warning chime) to combinationmeter with communication line.
When combination meter receives buzzer output signal (ignition key warning chime), it sounds the buzzer.
When Intelligent Key Is Carried With The Driver
Refer to BL-78, "System Description".
LIGHT WARNING CHIME
With ignition switch in LOCK or ACC position, driver 's door is opened, and lighting switch in 1ST or 2ND posi-
tion, the light warning chime will sound.
BCM detects ignition switch in LOCK or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to unified meter and A/
C amp. with CAN communication.
Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter with
communication line.
When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer to BCS-4, "
System Description".
SEAT BELT WARNING CHIME
With ignition switch turned ON and driver's seat belt unfastened, seat belt warning chime will sound for
approximately 6 seconds.
Combination meter reads a ON/OFF signal from seat bel t buckle switch (driver side), and transmits seat belt
buckle switch signal to unified meter and A/C amp. with communication line.
BCM receives seat belt buckle switch signal from unified meter and A/C amp. with CAN communication.
BCM detects ignition switch turned ON and seat bel t 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.
