WARNING CHIME

2007 Pathfinder

NOTE:
When ignition key warning chime, light warning chime, and seat belt warning chime are required 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

LIGHT WARNING CHIME

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

●

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

●

to BCM terminals 2, 3, 4, 5, 6, 32, 33, 34, 35 and 36.

NOTE:
Lighting switch (detected by BCM) is in 1st or 2nd position. Refer to 

BCS-3, "COMBINATION SWITCH

READING FUNCTION"

 .

Ground is supplied

●

to BCM terminal 47

●

through front door switch LH terminal 2. 

Front door switch LH is case grounded.
BCM detects headlamps are illuminated, and sends light warning signal to combination meter via CAN com-
munication lines. When the combination meter receives light warning signal, it sounds warning chime.

IGNITION KEY WARNING CHIME

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

●

through key switch terminal 1

●

to BCM terminal 37.

Ground is supplied

●

to BCM terminal 47

●

through front door switch LH terminal 2. 

Front door switch LH is case grounded.
BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter via CAN
communication lines. When the combination meter receives key warning signal, it sounds warning chime.

SEAT BELT WARNING CHIME

When the ignition switch is turned ON with the driver seat belt unfastened (seat belt buckle switch LH unfas-
tened), warning chime will sound for approximately 6 seconds.
Ground is supplied

●

to combination meter terminal 24

●

through seat belt buckle switch LH terminal 1.

Seat belt buckle switch LH terminal 2 is grounded through body grounds B7 and B19.
The combination meter sends seat belt buckle switch LH unfastened signal to BCM via CAN communication
line.
BCM receives seat belt buckle switch LH unfastened signal from combination meter via CAN communication
line, and sends seat belt warning signal to the combination meter via CAN communication line. When the
combination meter receives the seat belt warning signal, it sounds the warning chime. The BCM controls the
(6 second) duration of the seat belt warning chime.
