Keyless/Power Door Locks/Security System Description - Control/Function (2014 2015)
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 lock and unlock trunk. The trunk can be locked by switching to valet mode.
Glove Box Control
When there is input from the glove box opener switch to the MICU, the MICU operates the glove box opener solenoid. The glove box can be locked by switching to valet mode.
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 by 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 opener solenoid 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 (remote in the vehicle), the system will not lock the doors. If the driver manually locks and closes the doors with a remote in the vehicle (input ON), the MICU energizes the driver's door actuator and unlocks the driver's door.
When the trunk is closed with the remote left in the trunk, the RF unit detects the location of the remote and does not lock the trunk.
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 all the doors.
Automatic Door Lock Function:
- When the vehicle speed exceeds 9 mph (15 km/h).
- When the shift position/mode is out of the P position/mode.
Automatic Door Unlock Function:
- When the vehicle mode is change to the OFF (LOCK) mode from the ON mode.
- When the shift position/mode is moved to the P position/mode from other than P position/mode.
- When the driver's door switch is ON (door open).
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 customizing function. For more information about customize options, refer to the Owner's manual.
Security Control
When the security alarm is set, the MICU sends the security set signal using B-CAN. You can select the use of security control through the customize function.

Security Setting
When the security alarm is set, the MICU sends the security set signal using B-CAN. When the gauge control module receives the security set signal from the MICU, the security indicator flashes to indicate the system is arming.
Security Alarm
With the security system armed, manually opening the hood or the trunk, or moving an interior 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 battery, the alarming state cannot be changed. The alarm starts again when reinstalling the battery.
Security Answer Back Control
When using the remote, the MICU provides an answer back function to alert the client that the MICU received a lock or unlock command from the remote. When the MICU receives a lock signal, it sends signals once to the parking lights, the taillights, the license plate lights, the side marker lights, and the keyless buzzer. When the MICU receives an unlock signal, the MICU sends signals two times to the parking lights, the taillights, the license plate lights, the side marker lights, and the keyless buzzer.
When the MICU receives a lock signal, the MICU sends signals once to the parking lights, the taillights, the license plate lights, the side marker lights, and 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 parking lights, the taillights, the license plate lights, and the side marker lights.
