Anti-Theft

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

NOTE: The convertible top (if equipped), the luggage compartment lid, and all doors must be closed for the interior motion sensing feature to activate.

NOTE: The perimeter alarm system includes a motion detection system that monitors the vehicle interior and a vehicle inclination sensor that detects changes in vehicle inclination.

NOTE: The inclination sensing feature must be disarmed before raising the vehicle on a hoist to prevent false alarms.

The perimeter alarm system consists of:

• Anti-theft hood switch (located in the right front corner of the engine compartment)
• Convertible top ajar switch (if equipped) (located behind the RH side of the rear seat)
• Door ajar switches (part of the door latch)
• Door disarm switch (driver door only) (part of the door latch)
• Door lock control switch
• Intrusion and inclination sensor (located in the overhead console)
• Luggage compartment lid ajar switch (part of the luggage compartment lid latch)
• Remote Keyless Entry (RKE) transmitter
• Traffic horn
• Body Control Module B (BCM-B)
• SJB

The anti-theft perimeter alarm feature is controlled by the SJB . The perimeter alarm system is designed to warn the driver in the event of an unauthorized entry to the vehicle and is also designed to help prevent the unwanted towing of the vehicle. When the vehicle is locked and armed, the perimeter alarm system monitors the following:

• Doors
• Hood
• Luggage compartment lid
• Movement inside the vehicle
• Variations in vehicle inclination/tilt

If an unauthorized activation of the above inputs occurs (an activation occurring with the system armed), the system flashes the turn signals and sounds the traffic horn.

The interior motion detection and vehicle inclination sensing systems operate only when the vehicle is locked using the RKE transmitter or when using the door lock control switch with the accompanying door open and both doors are then closed. For vehicles with a convertible top, the top must be fully closed and latched for the interior motion sensing system to arm. If the vehicle is locked using the key in the driver door lock cylinder, the system monitors the doors, the luggage compartment lid and the hood, but the interior motion and the vehicle inclination sensing does not arm. If necessary, the vehicle inclination sensing and the interior motion sensing features will not arm if both doors are locked using the manual push buttons, then closing the door, or using the manual push button on the passenger door and then locking the driver door with the key in the door lock cylinder. The former step will not cause any part of the perimeter alarm to be armed, while the latter step arms the perimeter alarm, but not the interior motion and vehicle inclination sensing features. For correct operation of the interior motion detection system, all the windows must be closed prior to arming the system. This prevents accidental alarm activation due to external influences and makes sure that correct interior motion detection occurs. The interior motion sensing system does not arm if either door is ajar.

The BCM-B sends a message over the local interconnect network to the intrusion and inclination sensor to disarm if the SJB is commanded to open the luggage compartment lid, or open a window or unlock the door locks. If any of these events occurs, the SJB sends a message over the Medium Speed Controller Area Network (MS-CAN) to the BCM-B , which signals the intrusion and inclination sensor to disarm.

Arming the System

When armed, the perimeter alarm system is designed to notify the driver of an unauthorized entry. When an unauthorized entry or towing occurs, the system flashes the turn signal lamps and interior lamps and sounds the anti-theft alarm horn and the traffic horns. The system is ready to arm whenever the key is out of the ignition lock cylinder. Any of the following actions arm the alarm system:

• Pressing the RKE transmitter lock control one time to arm the system
• Locking all the doors using the door lock control switch while the driver or passenger door is open, and then closed
• Locking the driver door with the key in the driver door lock cylinder (this does not arm the interior motion or vehicle inclination sensing systems)

NOTE: Deactivating an activated alarm by pressing the PANIC button on the RKE transmitter returns the system to an armed state.

NOTE: Opening the luggage compartment lid inhibits the interior motion and inclination sensing systems, but the perimeter alarm continues to monitor the doors and hood. Once the luggage compartment lid is closed, the interior motion sensing system is again monitored.

If all the closures (doors, luggage compartment lid and hood) are closed, the turn signal lamps flash once if the LOCK button on the RKE transmitter is pressed once. If the vehicle is locked again within 3 seconds using the RKE transmitter, the vehicle locks again, the turn signal lamps flash and the horn chirps. If any closure is not correctly closed, the turn signal lamps do not flash, the horn chirps twice, and the perimeter alarm will not arm. The system waits 20 seconds after the vehicle has been correctly locked before arming the perimeter alarm. After the 20 second pre-arm phase, the door lock control switch is disabled to further protect the vehicle.

Disarming the System

The perimeter alarm system can be disarmed by:

• unlocking the doors using the RKE transmitter.
• unlocking the driver door with the key in the driver door lock cylinder.
• turning the ignition key to the ON position with a programmed Passive Anti-Theft System (PATS) ignition key.
