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, 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
