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, a tailgate release 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 tailgate release signal to the MICU via the B-CAN.
Remote Search Function
Determines if the remote is present inside the vehicle during operation.
Key Lockout Prevent Function
The lockout prevent 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.
Electric Steering Lock (Except USA mode ls with CVT)
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.
Lighting and Indicator Function
The keyless access control unit controls the engine start/stop switch indicator, and illuminates the keyless access indicators in the gauge control module.
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 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.
Immobilizer Function
The immobilizer function uses the GEN 6 protocol, and the immobilizer function is deactivated by mutual communication between the keyless access control unit, the PCM, and the MICU via the S-NET.
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 information display (Only at the vehicle is 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 indicator and an alarm will sound. Command to display shift to P warning (CVT) should be transmitted via the B-CAN.
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 for any reason you need to shut off the engine while the vehicle is in motion, press the engine start/stop switch button quickly 2 times, or hold the engine start/stop button for 1. 5 seconds. The engine turns off, and the vehicle mode switches to ACCESSORY. In this mode, the steering wheel remains unlocked. (With electric steering lock)
Panic Function
When you press the PANIC button on the 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.
