Remote

The remote is equipped with a keyless transmitter, so both doors can be locked and unlocked by a lock/unlock button operation, even from a remote distance from the vehicle. When the key lock button or key unlock button is pressed, the keyless transmitter sends the applicable switch signal to the RF unit. After receiving the authentication at between RF unit and keyless access control unit, the door lock/unlock signals are sent to MICU through B-CAN communication.
