Basic Principle

The working principle of central control and anti-theft system is shown in Fig.3.74.Press the unlock button of remote control key,and the key must be certified with the vehicle body control module through low-frequency magnetic field.If the remote control key fails to be certified with the vehicle body control module,the vehicle protection of vehicle body control module can’t be disabled,thus,the door can’t be opened.

When the key is not in IGN ON/ACC position,and the four doors are closed together,receiving the lock order from the remote control key,the whole car enters the fortifying mode.If any door is not closed and it receives the lock order from the remote control key,the turn light illuminates twice and the buzzer sounds once,and the central control will lock first and then unlock.When receiving the unlock order from the remote control key,the whole car is out of the fortifying mode,and at the moment,the turn light illuminates twice.

Under the fortifying mode,long press the trunk open button of remote control key,the trunk opens,the turn light illuminates twice without anti-theft horn warning.

Fig.3.74 Working Principle of Central Control and Anti-theft System

Under the fortifying mode,if any door is opened illegally,it enters the alarm mode with anti-theft horn warning and the turn light illuminating.

When the key is plugged out and four doors and one trunk are closed,the whole car is in the fortifying condition,at this moment,use the remote control to unlock,and if there is no further action(open the door or the trunk),after a while,the four doors are locked,the whole car enters fortifying mode and the central control locks again.
