Anti-Theft - Perimeter

ANTI-THEFT- PERIMETER ALARM SYSTEM

The anti-theft perimeter protection feature is controlled by the front electronic module (FEM), the rear electronic module (REM), and the driver door module (DDM). The alarm can be armed using the LOCK button in the remote transmitter to the DDM, which sends a message through the Standard Corporate Protocol (SCP) communications network to the FEM; or by using the driver or passenger door lock switch if the corresponding door is open when LOCK is actuated; or by locking the vehicle with the key in the driver door lock cylinder or the keypad by pressing 7/8 and 9/0 simultaneously. The FEM and REM will then monitor all features, which will activate the alarm in the event of an unauthorized entry.

The luggage compartment lid key cylinder will not disarm the vehicle's perimeter alarm. The luggage compartment alarm can be temporarily inhibited through the luggage compartment lid disarm switch, located in the luggage compartment lock key cylinder or opening the luggage compartment with the remote entry key fob or the keypad. Once the luggage compartment lid closes, the perimeter alarm system will immediately start monitoring the luggage compartment. The perimeter alarm can only be disarmed by unlocking the vehicle using the remote transmitter or the driver door lock cylinder switch, or by cycling to RUN a valid programmed key in the ignition switch or by entering the correct vehicle unlock code on the keypad.

Additionally, an ignition switch tamper circuit and a signal headwire line from the FEM to the REM are monitored.

If any of the above features receive any activation once the alarm has been armed, the alarm will activate the visual and audible alerts.
