DESCRIPTION

The Thatcham Alarm monitors the vehicle doors, liftgate, hood, and the interior of the vehicle for unauthorized operation. The vehicle doors, liftgate, and hood use ajar switches as inputs to the BCM to indicate their current status. The interior of the vehicle is secured by the use of Intrusion Sensors. The Intrusion Sensors are used as inputs to the interface module to report any motion in the interior of the vehicle. The interface module is located above the courtesy lamp assembly in the headliner. The alarm activates by sounding the siren, and flashing the hazard lamps.

The Coupe uses an Ultrasonic System with two sensors facing rearward attached to the inside of the windshield below the headliner and above the mirror.

The Roadster uses a Microwave Sensor located in the console below the cupholder.
