COMBINATION METER
 The buzzer (1) for the warning chime system is integrated in the
combination meter.
 The combination meter sounds the alarm buzzer installed in the
combination meter when receiving the buzzer output signal trans-
mitted from each unit.
BCM
BCM receives signals from various units and transmits a buzzer output signal to the combination meter via
CAN communication if it judges that the warning buzzer should be activated.

LIGHT REMINDER WARNING CHIME : System DescriptionINFOID:0000000003838696
DESCRIPTION
With ignition switch in the OFF or ACC position, when the driver door is open or the lighting switch is the 1st or
2nd position, the light warning chime will sound.
 BCM detects ignition switch in the OFF or ACC position, front door switch (driver side) ON, and lighting
switch in 1st or 2nd position. Then the BCM transmits the buzzer output signal (light reminder warning
chime) to combination meter with CAN communication line.
 When combination meter receives buzzer output signal (light reminder warning chime), it sounds the buzzer.
WARNING OPERATION CONDITIONS
If all of the following conditions are fulfilled.
 Ignition switch is in the OFF or ACC
 Lighting switch is in the 1st or 2nd position
 Front door switch (driver side) is ON
WARNING CANCEL CONDITIONS
Warning is canceled if any of the following conditions is fulfilled.
 Lighting switch OFF
 Ignition switch ON
 Front door switch (driver side) is OFF

DescriptionINFOID:0000000003838708
 The buzzer for warning chime system is installed in the combination meter.
 The combination meter sounds the alarm buzzer based on the signals transmitted from various units.
Component Function CheckINFOID:0000000003838709
1.CHECK OPERATION OF METER BUZZER
1. Select “BUZZER” of “BCM” on CONSULT-III.
2. Perform “LIGHT WARN ALM” of “Active Test”.
Does meter buzzer beep?
YES >> INSPECTION END
NO >> GO TO 2.
2.CHECK COMBINATION METER INPUT SIGNAL
Select the “Data Monitor” for the “METER/M&A” and check the “BUZZER” monitor value.
Is the inspection result normal?
YES >> Replace combination meter.
NO >> Replace BCM. Refer to BCS-78, "
Removal and Installation".
Diagnosis ProcedureINFOID:0000000003838710
1.CHECK POWER SUPPLY OF COMBINATION METER
Check power supply of combination meter. Refer to WCS-19, "
COMBINATION METER : Diagnosis Proce-
dure".
Is the inspection result normal?
YES >> INSPECTION END
NO >> Repair power supply circuit of combination meter. Refer to WCS-19, "
