IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)
With the key inserted into the key switch, and the ignition 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, ignition 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 ignition 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.

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.
When Intelligent Key Is Carried With The Driver

WARNING CHIME
Revision: 2006 July 2007 FX35/FX45
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-3, "
COMBINATION SWITCH READING FUNCTION" .
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 belt 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 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
