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.
Keyless Door Lock Control
The remote can transmit a lock or unlock signal to the keyless access/TPMS 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 relock timer value.
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.
Automatic Door Lock/Unlock Control
The automatic door lock control function allows the MICU to detect the status of B-CAN signals and various switch signals and control each actuator in order to automatically lock all the doors when the vehicle speed exceeds 15 km/h (9 mph). Or, it allows the MICU to detect that the shift position is out of the P position and control actuator to automatically lock all the doors. The locking method can be set as non-link, link to vehicle speed, link to shift position and link to engine start/stop switch by customizing function.
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 tailgate, or moving an interior lock knob to the unlock position activates the security alarm. Alternatively, the security alarm sounds and, the headlights low beam, position lights, taillights, license plate lights, and side marker lights blinks, repeating this alarm (one cycle is 120 seconds) 10 times at maximum. Even if you remove the 12 volt battery, the alarming state cannot be changed. The alarm starts again when reinstalling the 12 volt 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, taillights, license plate lights, side marker lights, keyless/power tailgate outside buzzer. When the MICU receives an unlock signal, the MICU sends signals two times to the parking lights, taillights, license plate lights, side marker lights, and keyless /power tailgate outside buzzer.
When the MICU receives a lock signal, the MICU sends signals once to the position lights, taillights, license plate lights, side marker lights, and keyless/power tailgate outside 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 position lights, taillights, license plate lights, side marker lights.
