NOTE:
When ignition key warning chime, light warning chime, and seat belt warning chime should be conducted at
the same time, the priorities for each chime are the following.

1.

Light warning chime

2.

Ignition key warning chime

3.

Seat belt warning chime

IGNITION KEY WARNING CHIME

With the key inserted into the ignition switch, and the driver's door open, the warning chime will sound.
Power is supplied

●

through key switch and key lock solenoid terminal 4

●

to BCM terminal 62.

Ground is supplied

●

to unified meter and A/C amp. terminal 8

●

through driver side door switch terminal 4.

Driver side door switch is case grounded.
Unified meter and A/C amp. send door open signal to BCM with CAN communication line.
BCM detects key inserted into the ignition switch, and sends key warning signal to unified meter and A/C amp.
with CAN communication line. Unified meter and A/C amp. sends key warning signal to combination meter
with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives key warning signal, it sounds warning chime.

LIGHT WARNING CHIME

With the key removed from the ignition switch, the driver's door open, and the lighting switch in 1st or 2nd posi-
tion, the warning chime will sound. [Except when headlamp battery saver control operates (for 5 minutes after
ignition switch is turned to OFF or ACC position) and headlamps do not illuminate.]
Signal is supplied

●

from combination switch (lighting switch) terminals 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

●

to BCM terminals 40, 41, 42, 43, 47, 48, 49, 50, 51 and 52.

NOTE:
BCM detected lighting switch in 1st or 2nd position, refer to

LT-251, "Combination Switch Reading Func-

tion"

.

Ground is supplied

●

to unified meter and A/C amp. terminal 8

●

through driver side door switch terminal 4.

Driver side door switch is case grounded.
Unified meter and A/C amp. send door open signal to BCM with CAN communication line.
BCM detects headlamps are illuminated, and sends light warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends light warning signal to combination meter with
communication line between unified meter and A/C amp. and combination meter.
When combination meter receives light warning signal, it sounds warning chime.

SEAT BELT WARNING CHIME

With ignition switch turned ON and seat belt unfastened [seat belt buckle switch (driver side) ON], warning
chime will sound for approximately 6 seconds.
Ground is supplied

●

to combination meter terminal 3

●

through seat belt buckle switch (driver side) terminal 50.

Seat belt buckle switch (driver side) terminal 65 is grounded through body grounds B7 and B20.
Combination meter sends seat belt unfastened [seat belt buckle switch (driver side) ON] signal to unified
meter and A/C amp. with communication line between unified meter and A/C amp. and combination meter.
BCM receives seat belt unfastened [seat belt buckle switch (driver side) ON] signal from unified meter and A/
C amp. with CAN communication line, and sends seat belt warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends seat belt warning signal to combination meter
with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives seat belt warning signal, it sounds warning chime.

CAN Communication System Description

AKS004H0

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
