Grand Cherokee 4WD V8-5.7L (2008)
Alarm Module: Description and Operation
An intrusion module (1) is part of the premium version of the Vehicle Theft Alarm (VTA) in the Vehicle Theft Security System (VTSS). The premium
version of the VTA is only available in vehicles built for certain markets, where the additional features offered by this system are required. The intrusion
module is located in the passenger compartment. This unit is designed to work in conjunction with the intrusion sensor transmitter and intrusion sensor
receiver to provide interior motion detection and serves as the interface between the Front Control Module (FCM), the ElectroMechanical Instrument
Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and the alarm siren.
The intrusion module has two integral mounts (2) that are secured by nuts to two weld studs on the right quarter inner panel just behind the right rear
wheel house. The module is concealed beneath the quarter inner trim panel. Concealed within the molded plastic housing is the circuitry of the module,
which includes a microprocessor. The module is connected through an integral connector receptacle (3) to the vehicle electrical system by a take out and
connector of the body wire harness.
The intrusion module unit cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.
