Keyless Access System Description - Components (2014)
RF (Radio Frequency) Unit
The RF unit is located on the rear shelf. The RF unit identifies the Honda smart key's code.
LF (Low Frequency) Antennas
The front interior, middle 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 Honda smart key outside of the vehicle.
Electric Steering Lock
The electric steering lock has built in the control unit, and it controls the steering lock solenoid. When keyless remote code is identified, the control unit makes the steering lock solenoid release. The keyless access control unit recognizes a steering lock solenoid unlock then it sends a key switch unlock signal to the MICU.
Touch Sensors and Lock Buttons
The touch sensors and lock buttons 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 lock button on the door outer handle to lock the doors.
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 between RF unit and keyless access control unit, the door lock/unlock signals are sent to MICU through B-CAN communication.
Power Switch
When pressing the power switch, it changes the vehicle to OFF, ACCESSORY, ON, or READY TO DRIVE mode.
The power switch also includes an LF antenna. It receives the immobilizer signal from the keyless access control unit.
Answer Back Buzzer
The answer back buzzer located inside the rear bumper sounds when locking and unlocking or for alarming.
