Keyless/Power Door Locks/Security System Description - Control/Function
Door Lock Control
The door lock control function allows the MICU to detect the status of various switch signals and control each actuator in order to lock and unlock doors.

Trunk Lid Control
The trunk lid control function allows the MICU to detect the status of various switch signals and control trunk lid release actuator in order to unlock trunk.

Keyless Door Lock Control
The remote can transmit a lock or unlock signal to the keyless access control unit, which sends the keyless request to the MICU using the B-CAN, then the MICU controls the door lock actuator(s) by the B-CAN signal and various switch signal.

Keyless Door Lock Control (Trunk Lid)
The remote can transmit a lock or unlock signal to the keyless access control unit, which sends the keyless request to the MICU using the B-CAN, then the MICU controls the trunk lid release actuator by the B-CAN signal and various switch signal.

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.

Automatic Door Lock/Unlock Control
The automatic door lock/unlock control function allows the MICU to detect the status of B-CAN signals and various switch signals and controls each actuator in order to automatically lock/unlock the doors.

Automatic Door Lock Function:
When the vehicle speed exceeds 9 mph (15 km/h). (Default setting)
When the shift position/mode is out of the P position/mode.

Automatic Door Unlock Function:
When the driver's door is open. (Door switch ON) (Default setting)
When the shift position is moved to the P position from other than P position.
When the vehicle mode is changed to the OFF (LOCK) mode from the ON mode.

Alternatively, the security alarm sounds and the headlights low beam, the parking lights/daytime running lights, the taillights, the license plate lights, and the side marker lights blink, repeating this alarm (one cycle is 120 seconds) 10 times maximum. Even if you disconnect the battery, the alarming state cannot be cancelled. The alarm starts again when reconnecting the battery.
