IGNITION KEY WARNING CHIME (WITHOUT INTELLIGENT KEY)

With the key inserted into the key switch, and the ignition switch in the OFF or ACC position, when driver's door is opened, the warning chime will sound.
- BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with
CAN communication line.
- When combination meter receives key warning signal, it sounds warning chime.






IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)

When Mechanical Key Is Used
With the key inserted into the key switch, and the ignition switch in the LOCK or ACC position, when driver's door is opened, the warning chime will sound.
- BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with
CAN communication line.
- When combination meter receives key warning signal, it sounds warning chime.





When Intelligent Key Is Carried With The Driver
System Description.

LIGHT WARNING CHIME

The warning chime sounds, when driver's door is opened (door switch ON) with lighting switch ON and the ignition switch is in any position other than ON or START.
NOTE:
BCM detected lighting switch in the 1st or 2nd position, Combination Switch Reading Function.
- BCM detects headlamps are illuminated, and sends light warning signal to combination meter with CAN
communication lines.
- When the combination meter receives light warning signal, it sounds warning chime.






SEAT BELT WARNING CHIME

With the ignition switch turned ON and driver's seat belt unfastened, the seat belt warning chime will sound for approximately 6 seconds.
- The combination meter reads an ON/OFF signal from the seat belt buckle switch LH, and transmits the seat belt buckle switch signal to the BCM with CAN communication.
- The BCM detects the ignition switch turned ON and seat belt buckle switch LH ON. And then, transmits the buzzer output signal (seat belt warning chime) to the combination meter with CAN communication.
- When the combination meter receives the buzzer output signal (seat belt warning chime), it sounds the buzzer.






PARKING BRAKE WARNING CHIME

The parking brake warning chime sounds when the parking brake is applied and vehicle speed reaches approximately 2 km/h (1 MPH).
- The combination meter receives a parking brake applied signal from the parking brake switch.
