Keyless/Power Door Locks/Security System Description - Control/Function (2019 2020 2021)
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.
Tailgate Control
In the tailgate release function, the MICU activates the tailgate release actuator by the tailgate outer handle switch operation when the vehicle runs at a speed less than 1.2 mph (2 km/h). The tailgate can be unlocked by the tailgate outer handle switch operation without having the remote if all the doors are unlocked.
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. 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.

Keyless Tailgate Unlock Control
By pressing the keyless transmitter *1 or the remote *2 tailgate button when each of the door is locked with the vehicle in the OFF (LOCK) mode, the keyless tailgate unlock control simultaneously shifts the mode to the tailgate unlock mode and performs the answerback. After shifting to the tailgate unlock mode, the tailgate can be unlocked by operating the tailgate outer handle switch. If the tailgate is not unlocked for a certain time period after the tailgate unlock mode is set, the mode shifts to the tailgate lock mode, and the tailgate outer handle switch operation is disabled.

Key Lockout Prevent Function
The body control module monitors whether or not there are the key insert to the ignition switch *1 or the remote in the vehicle *2. If the key insert to the ignition switch *1 or the remote is in the vehicle *2, the system will not lock the doors. If the driver manually locks and closes the doors with the key insert to the ignition switch *1 or remote in the vehicle *2, the MICU energizes the door lock actuator and unlocks the door. Also, if the tailgate is closed when the remote is left in the vehicle with all the door closed and the driver's door lock knob at lock position, the tailgate can be unlocked by the tailgate outer handle switch operation. In addition, when the key lockout prevent function operates, the answer back is performed.

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. (CVT)
Automatic Door Unlock Function:
- When the driver's door switch is ON (door open). (Default setting)
- When the shift position/mode is moved to the P position/mode from other than P position/mode. (CVT)
- When the vehicle mode is changed to the OFF (LOCK) mode from the ON mode.
Customizing Function:
The locking method can be set as non-link, link to vehicle speed, link to shift position/mode, or link to ignition switch or engine start/stop switch by the customizing function. For more information about customize options, refer to the Owner's manual.
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.

*2: With keyless access system
When the MICU receives a lock signal, the MICU sends signals once to the turn signal lights, and the horn* 1 or the keyless buzzer* 2 will sound once when you press the LOCK button again within 5 seconds.

Security Setting
When the security alarm is set, the MICU sends the security set signal using the B-CAN. When the gauge control module receives a security set signal from the MICU, the security indicator flashes at a slower pace to indicate the system has armed.
Security Alarm
With the security system armed, manually opening the hood or the tailgate or moving the door lock knob to the unlock position activates the security alarm. 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.
