Procedures
Intrusion Module Sensor - Removal — Transmitter
- Disconnect and isolate the battery negative cable.
- Pull the bezel (1) straight down from the headliner (3) to unsnap it from the transducer housing (2) of the intrusion sensor transmitter. Be certain to take the appropriate precautions not to soil or damage the headliner.
- Remove the trim from the upper liftgate opening. Header Panel - Removal.
- Partially remove the quarter trim panel from both upper D-pillars. Quarter Trim Panel - Removal.
- Carefully pull down the right rear edge of the headliner (1) from the upper liftgate opening far enough to reach between the headliner and the roof panel to access the transmitter (2) and mounting bracket (4) on the headliner substrate.
- Disconnect the take out of the overhead wire harness (1) from the connector receptacle on the right side of the transmitter housing.
- Release the two latch features (3) of the mounting bracket and disengage the transmitter from the locating pins of the bracket.
- Remove the transmitter from between the headliner and the roof panel.

Intrusion Module Sensor - Description — Transmitter
TRANSMITTER An intrusion sensor transmitter (2) 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. This unit is designed to work in conjunction with the intrusion sensor receiver to provide interior motion detection inputs to the intrusion module, which serves as the interface between the Totally Integrated Power Module (TIPM), the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and the alarm siren. The transmitter is located in the passenger compartment, where it is concealed above the headliner. A molded plastic mounting bracket with two locating pins engages the holes in two locating tabs (4) integral to the transmitter housing and the housing is secured in place by two latch features integral to the bracket. Only a small dedicated molded plastic transducer trim bezel secured by a snap fit to the tubular ultrasonic transducer housing and extends vertically downward from the base of the transmitter housing is visible below the right rear corner of the headliner. The trim bezel has a small round opening that faces the front of the vehicle through which the transducer is aimed. Concealed within the molded plastic transmitter housing is the circuitry of the transmitter which includes an ultrasonic transmit transducer (1). The transmitter is connected through an integral connector receptacle (3) to the vehicle electrical system by a take out and connector of the overhead wire harness that is integral to the headliner. The intrusion sensor transmitter cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced. The transmitter mounting bracket is serviced as a unit with the headliner. The transducer trim bezel is available for separate service replacement.
Intrusion Module Sensor - Description — Receiver
RECEIVER An intrusion sensor receiver (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. This unit is designed to work in conjunction with the intrusion sensor transmitter to provide interior motion detection inputs to the intrusion module, which serves as the interface between the Totally Integrated Power Module (TIPM), the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and the alarm siren. The receiver is located in the passenger compartment, where it is concealed above the headliner. A molded plastic mounting bracket with three integral latch features is secured to the right front corner of the mini-overhead console housing and engages three latch tabs integral to the receiver housing. The ultrasonic receiver transducer (2) is aimed through a small dedicated round opening in the right side of the overhead console forward of the reading lamps and is the only evidence of the receiver that is visible from the passenger compartment. Concealed within the molded plastic receiver housing is the circuitry of the receiver which includes the receive transducer. The receiver is connected through an integral connector receptacle (3) to the vehicle electrical system by a take out and connector of the overhead wire harness that is integral to the headliner. The intrusion sensor receiver cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced. The receiver mounting bracket is serviced as a unit with the overhead console.
