Keyless Access System Description - Control/Function
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 B-CAN.
Keyless Entry Function
The keyless access control unit receives the keyless transmitter signal from the remote. The keyless access control unit authenticates the RF signal, and sends a door lock/unlock signal and tailgate lock/unlock signal to the MICU and the power tailgate control unit (with power tailgate) via the B-CAN.
Backup Communication Function
The keyless access system has a backup communication feature: If the keyless battery goes dead, touch the remote to the engine start/stop switch on the dashboard. The remote transponder then receives an immobilizer code from the engine start/stop switch, allowing you to start the vehicle.
Key Lockedout Prevent Function
The lockout function observes the key switch signal input. If the input is "ON" (remote in the vehicle), the system will not lock the doors. If the driver manually locks and closes the doors with a remote in the vehicle (input ON), the MICU energizes the driver's door actuator and unlocks the driver's door. If the remote remains in the cargo area, the system will not lock the tailgate. If the tailgate is closed when the remote remains in the cargo area, the tailgate lock will not lock.
Remote Search Function
The function recognizes if the remote is present inside the vehicle during some operation or function. It also detects if the door is opened or closed in vehicle ACCESSORY/ON mode situation. When the remote is taken out of the vehicle, outside buzzer will sound and gauge control module (Only at vehicle ON mode) will show a warning.
Electric Steering Lock (With 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.
Alarm Function
This function detects if the door is opened or closed with the vehicle in the ACCESSORY or ON mode. When the remote is taken out of the vehicle, the keyless buzzer will sound and the gauge control module (Only at the vehicle 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 will show a warning and will sound an alarm.
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.
Immobilizer Function
The immobilizer function is activated by mutual authentication between the keyless access control unit, the PCM, and the MICU (IMOES) via the S-NET line.
Registration Facility
The keyless access control unit can store up to 6 remotes with the HDS.
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.
Customer Emergency
If you must stop the engine in an emergency situation, do either of the following:
- Press and hold the engine start/stop switch button.
- Press the engine start/stop switch button three times continuously.
