Keyless Access System Description - Components
LF (Low Frequency) Antennas
The front interior and rear interior LF antennas send the signals to the remote placed in the interior. The driver's door outer handle, front passenger's door outer handle, and rear bumper LF antennas send the signals to the remote outside of the vehicle. Door Touch Sensors and Outer Handle Lock Switches
The door touch sensors and the outer handle lock switches are built in the driver's and front passenger's door outer handles. To operate the door locks without the built-in key while carrying the remote, grip the door outer handle to unlock the doors, and press the outer handle lock switch to lock the doors. Remote
The remote is equipped with a keyless transmitter, and all the doors can be locked and unlocked by a lock/unlock button operation, even from a remote distance from the vehicle. When the lock button or unlock button is pressed, the keyless transmitter sends the applicable switch signal to the keyless access control unit. After receiving the authentication keyless access control unit, the door lock/unlock signals are sent to MICU through B-CAN. Engine Start/Stop Switch
Pressing the engine start/stop switch changes the vehicle mode to OFF (LOCK), ACCESSORY, or ON mode. The engine start/stop switch also includes an LF antenna. When operating the backup function, the engine start/stop switch receives the immobilizer signal from the remote, and sends the immobilizer signal to the keyless access control unit. Keyless Buzzer
The keyless buzzer located inside the rear bumper sounds when smart entry function. |
