Principles of Operation
PRINCIPLES OF OPERATIONPerimeter Anti-theft - Without The Memory Feature
The perimeter anti-theft system provides for vehicle security through an audible and visual notification if the vehicle doors, luggage compartment lid, or hood is opened without the system being disarmed. The system arms when:
- the doors, the luggage compartment lid and hood are closed.
- the key is OFF
- the vehicle is electronically locked using the remote keyless entry (RKE) transmitter, the RKE keypad, or the driver door lock control switch (with the driver door open).
There is a 20-second pre-arm delay after which each door, luggage compartment lid, and hood is armed. If a door, luggage compartment lid, or hood is open, the system still arms all the other doors. Only the open door, luggage compartment lid, or hood remains disarmed until it is closed. When the open entry point is closed, that entry point enters a 20-second prearm delay then arms.
The hood ajar switch and door ajar switches register as normally closed. The luggage compartment lid ajar switch registers as a normally open switch. The smart junction box (SJB) monitors the status of the hood ajar switch, the luggage compartment lid ajar switch and door ajar switches. If these switches indicate an open entry point, the SJB energizes the horn and flasher relays causing the horn to sound and the turn signal lamps to flash. The SJB turns off the anti-theft system when it receives an UNLOCK command through the:
- RKE keypad.
- RKE transmitter (located on the head of the integrated key).
- the driver door disarm switch (part of the driver door latch).
- a valid coded ignition key is turned to the RUN position.
