INFOID:0000000000964469

COMBINATION METER

• The buzzer (1) for warning chime system is installed in the combi-

nation meter.

• The buzzer sounds when the combination meter receives buzzer

output signal from each unit through unified meter and A/C amp.

UNIFIED METER AND A/C AMP.

The unified meter and A/C amp. transmits the buzzer output signal received from BCM with CAN communica-
tion line to the combination meter.

BCM

BCM receives signals from various units and transmits a buzzer output signal to the unified meter and A/C
amp. with CAN communication line if it judges that the warning buzzer should be activated.

DESCRIPTION

With ignition switch in OFF or ACC position, driver door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound. 
• BCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch in

1ST or 2ND position. And then transmits buzzer output signal (light reminder warning chime) to unified meter
and A/C amp. with CAN communication line.

• Unified meter and A/C amp. transmits buzzer output signal (light reminder warning chime) to combination

meter with 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

• Lighting switch is at 1st or 2nd position
• Ignition switch is at OFF or ACC
• Front door switch (driver side) is ON

WARNING CANCEL CONDITIONS

Warning is canceled if any of the following conditions is fulfilled.

• Lighting switch OFF
