INPUT SIGNAL AND OUTPUT SIGNAL

OPERATION DESCRIPTION

• When the BCM detects that each door request switch is pressed, it activates the outside key antenna and inside key antenna corresponding to the pressed door request switch and transmits the request signal to the Intelligent Key.

• If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and transmits the key ID signal to the BCM via remote keyless entry receiver.

• BCM receives the key ID signal and compares it with the registered key ID.

• BCM locks/unlocks each door (except back door).

• BCM sounds Intelligent Key warning buzzer (lock: 2 times, unlock: 1 time) and blinks hazard warning lamps (lock: 2 times, unlock: 1 time) at the same time as a reminder.
