IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
System Description in intelligent key system.
LIGHT WARNING CHIME
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 (driver side) ON, and lighting switch in
1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to unified meter and A/C amp. with CAN communication line.
- Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter with communication line.
- When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, System Description.
SEAT BELT WARNING CHIME
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 [seat belt buckle switch (driver side) ON] from unified meter and
A/C amp. with CAN communication line.
- BCM detects ignition switch turned ON and seat belt buckle switch (driver side) ON. And then transmits buzzer output signal (seat belt warning chime) to unified meter and A/C amp. with CAN communication line.
- Unified meter and A/C amp. transmits buzzer output signal (seat belt warning chime) to combination meter with communication line.
- When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
PARKING BRAKE RELEASE WARNING CHIME
The parking brake warning chime sounds when the parking brake is applied and vehicle speed reaches approximately 7 km/h (4.3 MPH) or higher.
- The combination meter receives a parking brake applied signal from the parking brake switch.
- The unified meter and A/C amp. receives the vehicle speed signal from the ABS actuator and electric unit
(control unit) via CAN communication line and transmits it to the combination meter by means of communication line.
