Keyless Access System Description - Control/Function (2014)
Smart Entry Function
The keyless access control unit detects the input signal of the door outer handle touch sensor or the door lock switch, and authenticates 2-way communication with the keyless remote. Then the keyless access control unit sends a door lock signal, door unlock signal, and an answer back buzzer signal to the MICU via B-CAN line.
Keyless Entry Function
The RF unit receives the keyless transmitter signal from the keyless remote then sends a RF signal to the keyless access control unit. The keyless access control unit authenticates the RF signal, and sends a door lock/unlock signal and trunk lid unlock signal to the MICU via the B-CAN line.
Backup Communication Function
The keyless access system has a backup communication feature: If the keyless battery goes dead, touch the keyless remote to the power switch on the dashboard. The keyless remote transponder then receives an immobilizer code from the power switch, allowing you to start the vehicle.
Key Lockout Prevent Function
The lockout function observes the key switch signal input. If the input is "ON" (keyless remote in the vehicle), the system will not lock the doors.
If the driver manually locks and closes the doors with a keyless remote in the vehicle (input ON), the MICU energizes the driver's door actuator and unlocks the driver's door.
If the keyless remote remain in the trunk, the system will not lock the trunk lid. If close the trunk lid when remain the keyless remote in the trunk, the trunk lid lock will not lock.
Fault Diagnosis Function
The system has a fault diagnosis function. If any malfunction occurs, the keyless access system indicator comes on in the gauge control module.
Keyless Remote Search Function
Determines if the keyless remote is present inside the vehicle during some operation or function.
Electric Steering Lock
The electric steering lock control unit is built into the electric steering lock, and it controls the steering lock motor. When the remote code is identified, the electric steering lock control unit unlocks the steering lock by controlling the steering lock motor.
Backup Fuse Check Function
The keyless access control unit checks the backup fuse. If the fuse is blown, the LF antenna does not output an LF wave. Once the keyless remote has been authenticated, this information is stored in the keyless access control unit.
Lighting and indicator Function
The keyless access control unit controls the power switch indicator, displays information in the multi-information display, and illuminates the keyless access system indicators in the gauge control module.
Registration Facility
The keyless access control unit can store up to 6 remotes with the HDS.

- Press and hold the power switch button.
- Press the power switch button three times continuously.
Panic Function
When you press the PANIC button on the keyless remote, the keyless access control unit sends a signal to the MICU via the B-CAN to sound the horn and activate the exterior lights.
