WARNING CHIME
Revision: November 20092006 QX56
System DescriptionEKS00BCP
FUNCTION
Power is supplied at all times

through 50A fusible link (letter f , located in the fuse and fusible link box)

to BCM terminal 70, and

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

to key switch and key lock solenoid terminal 3.
With ignition switch in ON or START position, power is supplied

through 10A fuse (No. 59, located in the fuse and relay box)

to BCM terminal 38.
Ground is supplied

to BCM terminal 67

through body grounds M57, M61, and M79.
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
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 and key lock solenoid terminal 4

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.
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:
BCM detected lighting switch 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 CAN communi-
cation lines. When the combination meter receives light warning signal, it sounds warning chime.
SEAT BELT WARNING CHIME
When the ignition switch is turned ON with the seat belt unfastened [seat belt buckle pre-tensioner assembly
LH (seat belt buckle switch) unfastened], warning chime will sound for approximately 6 seconds.
