Alternatively, the security alarm sounds, the headlights low beam, the parking lights, the taillights, the inner 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.
