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. |
| BCM | Judges the light warning conditions from the signals provided by various switches and transmits a buzzer output signal to the combination meter via CAN communication line if necessary. |
| Combination switch (Lighting switch) | Transmits the lighting switch position signal to BCM. |
| Front door switch LH | Transmits the door switch signal to BCM. |

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 belt buckle switch LH is ON (driver seat belt not fastened)
SEAT BELT WARNING CHIME : Component Description
| Unit | Description |
|---|---|
| Combination meter | Receives the seat belt buckle switch signal from the seat belt buckle switch and transmits it to BCM via CAN communication line. Receives a buzzer output signal from BCM via CAN communication line and sounds the buzzer. |
| BCM | Judges the seat belt warning condition from the seat belt buckle switch signal received from the combination meter and transmits a buzzer output signal to the combination meter via CAN communication line if necessary. |
| Seat belt buckle pre-tensioner assembly LH (seat belt buckle switch) | Transmits seat belt buckle switch signal to combination meter. |

KEY WARNING CHIME (WITH INTELLIGENT KEY) : Component Description
| Unit | Description |
|---|---|
| Combination meter | Receives key warning signal from BCM via CAN communication line and sounds the buzzer. |
| BCM | Judges the key warning condition using the door switch signal received from the front door switch LH, and the key switch signal received from the key switch and ignition knob switch. It then transmits a buzzer output signal to the combination meter via CAN communication line if necessary. |
| Front door switch LH | Transmits door switch signal to BCM. |
| Key switch and ignition knob switch | Transmits key switch signal to BCM. |

KEY WARNING CHIME (WITHOUT INTELLIGENT KEY) : Component Description
| Unit | Description |
|---|---|
| Combination meter | Receives key warning signal from BCM via CAN communication line and sounds the buzzer. |
| BCM | Judges the key warning condition from the door switch signal received from the front door switch LH, and the key switch signal received from the key switch and key lock solenoid. It then transmits a buzzer output signal to the combination meter via CAN communication line if necessary. |
| Front door switch LH | Transmits door switch signal to BCM. |
| Key switch and key lock solenoid | Transmits key switch signal to BCM. |
