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 the doors.
Tailgate Control (Without Power Tailgate)
The tailgate control function allows the MICU to detect the status of various switch signals and control tailgate release actuator in order to lock and unlock tailgate.
Tailgate Control (With Power Tailgate)
The tailgate control function allows the MICU to detect the status of various switch signals and sends the signals to the power tailgate control unit. The power tailgate control unit controls the power tailgate closer unit to lock or unlock the tailgate.
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.
Keyless Door Lock Control (Tailgate (Without Power Tailgate))
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 tailgate release actuator by B-CAN signal and various switch signal.
Keyless Door Lock Control (Tailgate (With Power Tailgate))
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 network, then the MICU controls the tailgate release actuator by 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 shift position/mode is moved to the P position/mode from other than P position/mode. (Default setting)
- 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.
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.
When the MICU receives a lock signal, the MICU sends signals once to the turn signal lights, and the horns or the keyless buzzer will sound once when you press the Lock button again within 5 seconds.
When the MICU receives an unlock signal, the MICU sends signals two times to the turn signal lights.
Security Control
When the security alarm is set, the MICU sends the security set signal using the B-CAN.

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. Alternatively, 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.
