A/T INDICATORPFP:24814
System DescriptionNKS003UV
A/T position is displayed in the dot matrix LCD in the combination meter.
MANUAL MODE
Unified meter and A/C amp. inputs manual mode signal and shift-up/down signal from A/T device (manual
mode switch), and transmits the signals to TCM with CAN communication.
TCM processes manual mode signal and shift-up/down signal, and transmits manual mode indicator sig-
nal and A/T position indicator signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits manual mode indicator signal and A/T position indicator signal to
combination meter with the communication line.
Combination meter indicates A/T gear position and manual mode indicator, when receiving manual mode
indicator signal and A/T position indicator signal.
NOT MANUAL MODE
Unified meter and A/C amp. inputs not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication.
TCM transmits A/T position indicator signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits A/T position indicator signal to combination meter with the commu-
nication line.
Combination meter indicates A/T shift position when receiving A/T position indicator signal.

WARNING CHIMEPFP:24814
System DescriptionNKS003UY
The buzzer (1) for warning chime system is installed in the com-
bination meter.
The buzzer sounds when the combination meter receives
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.
Ground is supplied
to BCM terminals 52,
to unified meter and A/C amp. terminals 55 and 71, and
to combination meter terminals 9, 10 and 11,
through grounds M16 and M70.

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.
