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
LIGHT REMINDER WARNING CHIME : Component Description
| Unit | Description |
|---|---|
| Combination meter | Receives a buzzer output signal from BCM via CAN communication line and sounds the buzzer. |

| Combination switch (lighting and turn signal switch) | Transmits the lighting switch position signal to BCM. |
| Front door switch LH | Transmits the door switch signal to BCM. |
LIGHT REMINDER WARNING CHIME COMPONENT DESCRIPTION
Scheme 56
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approximately 6 seconds.
- BCM receives seat belt buckle switch signal from combination meter with CAN communication line.
- BCM detects ignition switch turned ON and seat belt buckle switch LH ON and then transmits buzzer output signal (seat belt warning chime) to combination meter with CAN communication line.
- When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
If all of the following conditions are fulfilled
- Ignition switch OFF-->ON
- Seat buckle switch LH is ON (driver seat belt not fastened)
