Anti-Theft - Perimeter

Anti-Theft

The perimeter anti-theft alarm system consists of the following:

- Anti-theft alarm horn (inside the luggage compartment on the passenger side in 4-door sedans. Underneath the left rear D-pillar trim in 5-door hatchbacks.)

- Door ajar input

- Door lock control switch input

- Door disarm switch (part of the driver door latch)

- Hood switch (part of the hood latch)

- Liftgate/luggage compartment ajar input

- Remote Keyless Entry (RKE) transmitter

- Turn signals

- Body Control Module (BCM)


The perimeter alarm system protects the vehicle from unauthorized entry by sounding the horn and flashing the turn signals at regular intervals when the system is armed and any door, the hood, or liftgate/luggage compartment is opened without using the key in the driver door lock cylinder, the Remote Keyless Entry (RKE) transmitter, or the Intelligent Access (IA) feature.

Arming the Perimeter Alarm

The perimeter alarm is ready to arm any time when the ignition is off. Any of the following pre-arms the alarm system:

- pressing the LOCK button on a programmed RKE (Remote Keyless Entry) transmitter.

- pressing the door lock control switch to the LOCK position with the door open, then closing the door.

- turning the driver door lock cylinder to the LOCK position.

Once the system is pre-armed, there is a 11-second countdown before the perimeter alarm is armed. Each entry point to the vehicle (hood, door, or liftgate/luggage compartment) are armed separately and must be closed before that entry point begins the 11-second countdown to become armed. If all entry points (hood, doors, and liftgate/luggage compartment) are closed, the turn signals flash indicating all entry points are entering the 11-second countdown.

Disarming the Perimeter Alarm

The perimeter alarm can be disarmed by:

- pressing the UNLOCK button on a programmed RKE (Remote Keyless Entry) transmitter.

- pressing the liftgate/luggage compartment release button on a programmed RKE (Remote Keyless Entry) transmitter.

- turning the driver door lock cylinder to the unlock position.

- using a programmed key to transition the ignition to the RUN mode.

- unlock the driver door or all doors using the IA (Intelligent Access) feature.

Intelligent Access (IA) Key Disable

For security reasons, when the perimeter alarm enters an armed state, the Remote Function Actuator (RFA) module searches the interior of the vehicle for any programmed IA (Intelligent Access) keys. If the RFA (Remote Function Actuator) module detects any programmed IA (Intelligent Access) keys inside the vehicle when the perimeter alarm is armed, it disables the IA (Intelligent Access) key. The RKE (Remote Keyless Entry) and the IA (Intelligent Access) functions of that key still operate, but the RFA (Remote Function Actuator) module ignores any start command associated with that key. The disabled IA (Intelligent Access) key is enabled when the perimeter alarm is disarmed by pressing the RKE (Remote Keyless Entry) unlock button on the IA (Intelligent Access) key, using the IA (Intelligent Access) feature to unlock the doors, or by using the mechanical key blade in the door lock cylinder to unlock the doors.
