Keyless Door Lock Control
The keyless transmitter*1 or the remote*2 can transmit a lock or unlock signal to the immobilizer-keyless control unit*1 or the keyless access control unit*2, which sends the keyless request to the MICU using the B-CAN network, the MICU then controls the door lock actuator by B-CAN signal and various switch signals.
The customization menu can also set the timer value.

Key Lockout Prevent Function
The lockout prevent function observes the key switch signal input. If the input is "ON" (key insert to the ignition switch*1 or key present in the vehicle*2 ), the system will not lock the doors. If the driver manually locks and closes the doors with a key in the ignition switch*1 or remote in the vehicle*2 (input ON), the MICU energizes the driver's door lock actuator and unlocks the driver's door.

Answer Back Control
When using the keyless transmitter*1 or the remote*2, the MICU provides an answer back function to alert the operator that the MICU received a lock or unlock command from the keyless transmitter*1 or the remote*2.
When the MICU receives a lock signal, it sends the turn signal light signals once. When the MICU receives an unlock signal, the MICU sends the turn signal light signal two times.

Simultaneously, the security alarm sounds, the headlights low beam, the parking lights, the taillights, the license plate lights, and the side marker lights blink, repeating this alarm (one cycle is 120 seconds). Even if you remove the 12 volt battery, the alarming state cannot be changed.
The alarm starts again when reinstalling the 12 volt battery.
