Anti-Theft - Perimeter

Anti-Theft

NOTE: The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).

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

- Door ajar input
- Door lock control switch input
- Door disarm switch (part of the driver door latch)
- Hood switch
- Horn
- Liftgate ajar input
- Intelligent Access (IA) key
- Keyless entry keypad
- Turn signals
- Smart Junction Box (SJB)
- Driver Door Module (DDM)
- Remote Function Actuator (RFA) module

The perimeter alarm system protects the vehicle from unauthorized entry by sounding the horn and flashing the turn signals when an unauthorized entry occurs.

The perimeter alarm sounds the horn and flashes the turn signals in regular intervals when the system is armed and any door, the hood, or liftgate is opened without using the key in the driver door lock cylinder, the keyless entry keypad, the Remote Keyless Entry (RKE) transmitter, or the 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 the RKE transmitter (part of the IA key).
- pressing the door lock control switch to the lock position with the door open, then closing the door.
- touching and holding the 7/8 and 9/0 buttons simultaneously on the keyless entry keypad.
- turning the driver door lock cylinder to the lock position.

Once the system is pre-armed, there is a 20-second countdown before the perimeter alarm is armed. Each entry point to the vehicle (hood, door, or liftgate) are armed separately and must be closed before that entry point begins the 20-second countdown to become armed. If all entry points (hood, doors, and liftgate) are closed, the turn signals flash indicating that all entry points are entering the 20-second countdown.

Disarming the Perimeter Alarm

The perimeter alarm can be disarmed by:

- pressing the UNLOCK button on the RKE transmitter (part of the IA key).
- turning the driver door lock cylinder to the unlock position.
- using a programmed IA key to transition the ignition to the ON mode.
- entering the correct vehicle unlock code on the keyless entry keypad.
- unlock the driver door or all doors using the IA feature.

The perimeter alarm can be deactivated by pressing the PANIC button on an IA key. The turn signals stop flashing and the horn stops sounding, but the alarm is still armed.

Panic Alarm

The panic alarm operates similar to the perimeter alarm, but is only controlled by the panic button on the IA key. Refer to Handles, Locks, Latches and Entry Systems Description and Operation for information on the panic alarm operation.
