WARNING CHIMEPFP:24814
System DescriptionNKS00266

The 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.
IGNITION KEY WARNING CHIME
With the key inserted into the key switch, and the ignition switch in OFF or ACC position, when driver's door is
open, the ignition key warning chime sounds.

BCM detects key inserted into the key switch, ignition switch in OFF or ACC position, and driver side door
switch ON. And then, BCM 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.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, drivers door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sounds.

BCM detects ignition switch in OFF or ACC position, driver side door switch ON, and lighting switch in
1ST or 2ND position. And then, BCM 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 LT- 8 7 , "
Combination Switch Reading Function" .
