LIGHT REMINDER WARNING CHIME : System Description

INFOID:0000000001712824

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 LH ON, and lighting switch in 1ST or

2ND position. And then transmits 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

• Lighting switch is at 1st or 2nd position
• Ignition switch is at OFF or ACC
• Front door switch LH is ON
