Scheme 34
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, driver side door switch 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
- Driver side door switch is ON
LIGHT REMINDER WARNING CHIME : Component Description
| Unit | Description |
|---|---|
| Combination meter | Receives a buzzer output signal from the BCM and sounds the buzzer. |
| BCM | Judges the light reminder 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 combination switch input signal to BCM. |
| Driver side door switch | Transmits the driver side door switch signal to BCM. |
COMPONENT DESCRIPTION
Scheme 35
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approximately 6 seconds.
- The combination meter receives the seat belt buckle switch signal (driver side) from seat belt buckle switch (driver side) and transmits it to the BCM via CAN communication.
- The BCM receives seat belt buckle switch signal from combination meter via CAN communication.
- The BCM detects seat belt reminder warning based on the received signal and transmits the buzzer output signal to combination meter via CAN communication.
- The combination meter receives the buzzer output signal from BCM via CAN communication and sounds the warning buzzer.
If all of the following conditions are fulfilled, the warning buzzer will sound.
- Ignition switch ON
- Seat belt buckle switch (driver side) is ON (driver seat belt not fastened)
SEAT BELT WARNING CHIME : Component Description
| Unit | Description |
|---|---|
