Keyless Access System Description - Components
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 body control module. After receiving authentication, the body control module controls the door
lock/unlock actuator.
Door Touch Sensors and Outer Handle Lock Switches
The door touch sensors and the outer handle lock switches are built into 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 on the door outer handle to lock the doors.
LF (Low Frequency) Antennas
The front interior, rear interior, and rear shelf LF antennas send the signals to the remote placed in the interior. The driver's door, front
passenger's door, and rear bumper LF antennas send the signals to the remote when they are outside of the vehicle.
RF (Radio Frequency) Unit
The RF unit is composed of the internal RF unit, which is integrated with the body control module and the RF unit installed on the rear shelf. It receives signals from the remote.
Keyless Buzzer
The keyless buzzer located behind the rear bumper sounds when smart entry functions.
Power Switch
Pressing the power button changes the vehicle mode from OFF (LOCK), ACCESSORY, ON, or READY TO DRIVE mode. The power
switch also includes an LF antenna. When operating the backup function, the power switch receives the immobilizer signal from the
remote, and sends an immobilizer signal to the body control module.
