With any door open, if lock/unlock switch is used to lock doors, smart entrance control unit terminal 23 receives a ground signal:

With any door open, if the key is used to lock doors, smart entrance control unit terminal 41 receives a ground signal:

If these signals and lock signal from keyfob are received by the smart entrance control unit and ground signals of terminals 36 and 37 are interrupted (both front doors locked), the vehicle security system will activate automatically.

NOTE: Vehicle security system can be set even though the rear door is not locked.
Once the vehicle security system has been activated, smart entrance control unit terminal 31 supplies ground to terminal 2 of the security indicator lamp.
The security indicator lamp will illuminate for approximately 30 seconds and then blink every 2.6 seconds.
