buzzer output signal from each unit through unified meter and A/
C amp.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times

through 50A fusible link (letter F , located in the fuse and fusible link block)

to BCM terminal 55,

through 10A fuse [No. 21, located in the fuse block (J/B)]

to BCM terminal 42, and

to combination meter terminal 23,

through 10A fuse [No. 19, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 54.
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 53,

through 10A fuse [No. 14, located in the fuse block (J/B)]

to combination meter terminal 12.

WARNING CHIME
Revision: 2007 April2007 M35/M45
IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
Refer to BL-54, "WARNING FUNCTION" in intelligent key system.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.

BCM detects ignition switch in OFF 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 line.

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 seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.

BCM receives seat belt buckle switch signal [seat belt buckle switch (driver side) ON] from unified meter
and A/C amp. 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 unified meter and A/C amp. with CAN communication
line.

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.
