Keyless Door Lock Control 

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

Key Lockout Prevent Function 

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

Keyless Answer Back Control 

When using the keyless transmitter or the remote, the MICU provides an answer back function to alert the operator that the MICU received a lock or unlock command from the keyless transmitter or the remote. 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.
