Keyless Access System Description - Control/Function (2014 - 2015)
Smart Entry Function
The keyless access control unit detects the input signal of the door outer handle touch sensor or the outer handle lock switch, and authenticates 2-way communication with the remote. Then the keyless access control unit sends a door lock/unlock signal and an answer back signal to the MICU via the B-CAN.
Keyless Entry Function
The keyless access control unit receives the keyless transmitter signal from the remote, then sends an 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 release signal to the MICU via the B-CAN.
Backup Communication Function
When key authentication between the remote and the keyless access control unit is not possible because of a system abnormality or a drop of the battery voltage of the remote, the immobilizer function can be canceled by pressing the engine start/stop switch button once and bringing the remote close to the engine start/stop switch while the indicator of the engine start/stop switch is flashing. This causes the built-in immobilizer receiver of the engine start/stop switch to receive the immobilizer signal and to send the immobilizer signal to the keyless access control unit.
Electric Steering Lock (Canada models)
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.
Alarm Function
Detects the door open or close with the vehicle in the ACCESSORY/ON mode. When the remote is taken out of the vehicle, keyless buzzer will sound and multi-information display (Only at the vehicle is in the ON mode) will show a warning. Before the remote battery level falls to the point where the remote cannot be detected, the gauge control module (tach) will show a warning indicator and an alarm will sound. Command to display shift to P warning should be transmitted via the B-CAN.
Lighting and Indicator Function
The keyless access control unit controls the engine start/stop switch indicator, displays information in the multi-information display, and illuminates the keyless access system indicators in the gauge control module (tach).
Fault Diagnosis Function
The system has a fault diagnosis function. If any malfunction occurs, the keyless access indicator comes on in the gauge control module (tach).
Registration Facility
The keyless access control unit can store up to 6 remotes with the HDS.
Customer Emergency
When the engine start/stop switch is pressed continuously at least twice or once for 1.5 seconds or longer in an emergency while driving, the engine turns off, and the vehicle mode switches to ACCESSORY. In this mode, the steering wheel remains unlocked.
