A/T INDICATOR
Revision: 2006 December 2006 FX35/FX45
A/T INDICATORPFP:24814
System DescriptionNKS003HY
A/T shift position is displayed in the segment display in the combination meter.
MANUAL MODE

Unified meter and A/C amp. reads 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 shift 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 shift position indicator signal to
combination meter with the communication line.

Combination meter indicates shift gear position and manual mode indicator, when receiving manual mode
indicator signal and shift position indicator signal.
NOT MANUAL MODE

Unified meter and A/C amp. reads not manual mode signal from A/T device (manual mode switch), and
transmits the signals to TCM with CAN communication.

TCM transmits shift position indicator signal to unified meter and A/C amp. with CAN communication.

Unified meter and A/C amp. transmits shift position indicator signal to combination meter with the commu-
nication line.

Combination meter indicates A/T shift position when receiving shift position indicator signal.

WARNING CHIME
Revision: 2006 December 2006 FX35/FX45
WARNING CHIMEPFP:24814
System DescriptionNKS0030J

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)

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,

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

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.
