Description

Combination meter

• Receives the buzzer output signal from BCM via the CAN communication and sounds 

the buzzer.

• Judges that the parking brake is still applied according to the vehicle speed signal re-

ceived from the ABS actuator and electric unit (control unit) via CAN communication 
and the parking brake switch signal from the parking brake switch and sounds the 
warning buzzer.

• Receives the vehicle speed signal from the ABS actuator and electric unit (control unit) 

and the seat belt buckle switch signal (driver side) from the seat belt buckle switch (driv-
er side) and transmits them to BCM via CAN communication.

BCM

Based on the signals received from various units and switches, transmits the buzzer out-
put signal to the combination meter via CAN communication. 

TCM

Transmits the shift position signal to the BCM via CAN communication. 

ABS actuator and electric unit (control 
unit)

Transmits the vehicle speed signal to the combination meter via CAN communication.

Seat belt buckle switch (driver side)

Transmits the seat belt buckle switch signal (driver side) to the combination meter.

DESCRIPTION

With ignition switch in the OFF or ACC position, when the driver door is open and 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, 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 com-
bination 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
• 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
• Door switch (driver side) is OFF

Door switch (driver side)

Transmits the door switch signal (driver side) to BCM.

Parking brake switch

Transmits the parking brake switch signal to the combination meter.
