Alarm Module: Description and Operation Description DESCRIPTION An Intrusion Transceiver Module (ITM) is part of the export premium version of the Vehicle Theft

Alarm (VTA) in the Vehicle Theft Security System (VTSS). The export 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 ITM is integral to the rear dome lamp housing (1) located in the passenger compartment, on the lower surface of the headliner near the center of the vehicle. The ITM is designed to provide interior motion detection, and serve as an interface between the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and the alarm siren module.

The ITM is concealed within the dome lamp housing. Only the black grilled openings (4) for the ITM ultrasonic transmitter and receiver are visible on the outside of the housing, one each ahead and behind the dome lamp lens (3). The entire module is secured to the headliner by a fixed retainer (5) integral to the left side of the housing and a hinged retainer (2) on the right side that is integral to the dome lamp lens. A notch (6) in the housing at the left edge of the lens affords access for service removal.

Concealed within the housing is the electronic circuitry of the ITM which includes a microprocessor, and the ultrasonic transmit and receive transducers. A molded plastic connector receptacle on the circuit board is connected to the vehicle electrical system by a dedicated take out and connector of the headliner wire harness that is integral to the headliner.

The ITM unit cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced. The dome lamp lens and bulb are available for separate service replacement.

Alarm Module: Description and Operation Operation OPERATION The microprocessor in the Intrusion Transceiver Module (ITM) contains the motion sensor logic

circuits and controls all of the features of the export premium version of the Vehicle Theft Alarm (VTA). The ITM uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in the vehicle as well as with a diagnostic scan tool using the Controller Area Network (CAN) data bus. This method of communication is used by the ITM to communicate with the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN) and for diagnosis and testing through the 16-way data link connector located on the driver side lower edge of the instrument panel. The ITM also communicates with the alarm siren module over a dedicated serial bus circuit.

The ITM microprocessor continuously monitors inputs from its on-board motion sensor circuitry as well as inputs from the EMIC and the alarm siren module. The on-board ITM motion sensor circuitry transmits ultrasonic signals into the vehicle cabin through a transmit transducer, then listens to the returning signals through a receive transducer as they bounce off of objects in the vehicle interior. If an object is moving in the interior, a detection circuit in the ITM senses this movement through the modulation of the returning ultrasonic signals that occurs due to the Doppler effect. The motion detect function of the ITM can be disabled by depressing the LOCK button on the Remote Keyless Entry (RKE) transmitter three times within 15 seconds while the VTA is arming (security indicator is flashing rapidly). The ITM will signal the alarm siren module to provide a single siren chirp as an audible confirmation that the motion sensor function has been disabled.

If movement is detected while the VTA is armed, the ITM sends an electronic status message to the EMIC over the CAN data bus and sends an electronic message to the alarm siren module over a dedicated serial bus line to sound the siren. Then the EMIC relays an electronic request message to the Totally Integrated Power Module (TIPM) to flash the exterior lighting. When the EMIC detects a breach in the perimeter protection through a hard wired door or liftgate ajar switch input or receives a hood ajar switch input from the TIPM, it sends an electronic message to the ITM and the ITM sends an electronic message to the alarm siren module over a dedicated serial bus line to sound the siren.

The ITM also monitors inputs from the alarm siren module for siren battery or siren input/output circuit tamper alerts, and for siren battery condition alerts, then sets active and stored Diagnostic Trouble Codes (DTC) for any monitored system faults it detects. An active fault only remains for the current ignition switch cycle, while a stored fault causes a DTC to be stored in memory by the ITM. If a fault does not recur for 50 ignition cycles, the ITM will automatically erase the stored DTC.

The ITM is connected to the vehicle electrical system through the headliner wire harness. The ITM receives battery current through a fuse in the TIPM, and receives ground through the body wire harness. These connections allow the ITM to remain operational, regardless of the ignition switch position.

The hard wired circuits of the ITM may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the ITM or the electronic controls or communication between modules and other devices that provide some features of the VTA. The most reliable, efficient, and accurate means to diagnose the ITM or the electronic controls and communication related to ITM operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

Keyless Entry Module: Description and Operation Description DESCRIPTION The Sentry Key REmote Entry Module (SKREEM) (3) (also known as the Sentry Key Immobilizer

Module/SKIM or the Wireless Control Module /WCM) is the primary component of the Sentry Key Immobilizer System (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system and the Tire Pressure Monitor (TPM) system. The SKREEM is located on the right side of the steering column near the ignition lock cylinder housing and is concealed beneath the column shrouds. The molded black plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring (1) that extends from one side. When the SKREEM is properly installed, the antenna ring is oriented around the circumference of the ignition lock cylinder housing.

A single integral connector receptacle (4) is located adjacent to the antenna ring on the SKREEM housing. An integral molded plastic mounting tab (2) on the SKREEM housing has a hole in the center through which a screw passes to secure the unit to the steering column lock housing. The SKREEM is connected to the vehicle electrical system through a single take out and connector of the instrument panel wire harness.

The SKREEM cannot be adjusted or repaired. If ineffective or damaged, the entire SKREEM unit must be replaced.

Keyless Entry Module: Description and Operation Operation OPERATION The Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless Control

Module/WCM) contains a Radio Frequency (RF) transceiver and a microprocessor. The SKREEM transmits RF signals to, and receives RF signals from the Sentry Key transponder through a tuned antenna enclosed within the molded plastic antenna ring integral to the SKREEM housing. If this antenna ring is not mounted properly around the ignition lock cylinder housing, communication problems between the SKREEM and the transponder may arise. These communication problems will result in Sentry Key transponder-related faults.

The SKREEM also serves as the Remote Keyless Entry (RKE) RF receiver and, if the vehicle is so equipped, the receiver for the Tire Pressure Monitoring (TPM) system. See: Body and Frame/Locks/Power Locks/Description and Operation/Description or See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Description and Operation/Tire Pressure Monitoring (TPM) - Description. The SKREEM communicates over the Controller Area Network (CAN) data bus with the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), the Powertrain Control Module (PCM) or the diagnostic scan tool.

The SKREEM and the PCM both use software that includes a rolling code algorithm strategy, which helps to reduce the possibility of unauthorized Sentry Key Immobilizer System (SKIS) disarming. The rolling code algorithm ensures security by preventing an override of the SKIS through the unauthorized substitution of the SKREEM or the PCM. However, the use of this strategy also means that replacement of either the SKREEM or the PCM units will require a system initialization procedure to restore system operation.

The SKREEM retains in memory the ID numbers of any Sentry Key transponder that is programmed into it. A maximum of eight Sentry Key transponders can be programmed into the SKREEM. For added system security, each SKREEM is programmed with a unique Secret Key code. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded to the transponder of every Sentry Key that is programmed into the SKREEM. Therefore, the Secret Key code is a common element that is found in every component of the SKIS.

Another security code, called a PIN, is used to gain access to the SKREEM Secured Access Mode. The Secured Access Mode is required during service to perform the SKIS initialization and Sentry Key transponder programming procedures. The SKREEM also stores the Vehicle Identification Number (VIN) in its memory, which it learns through a CAN data bus message from the PCM during SKIS initialization.

In the event that a SKREEM replacement is required, the Secret Key code can be transferred to the new SKREEM from the PCM using the diagnostic scan tool and the SKIS initialization procedure. Proper completion of the SKIS initialization will allow the existing Sentry Keys to be programmed into the new SKREEM so that new keys will not be required. In the event that the original Secret Key code cannot be recovered, SKREEM replacement will also require new Sentry Keys. The diagnostic scan tool will alert the technician during the SKIS initialization procedure if new Sentry Keys are required.

When the key is inserted into the ignition switch and when the ignition switch is turned to the ON position, the SKREEM transmits an RF signal to excite the transponder in the ignition key. The SKREEM then waits for an RF signal response from the transponder. If the response received identifies the key as valid, the SKREEM sends an electronic valid key message over the CAN data bus. If the response received identifies the key as invalid or if no response is received from the key transponder, the SKREEM sends an invalid key message. The PCM will enable or disable engine operation based upon the status of the SKREEM messages. It is important to note that the default condition in the PCM is an invalid key ; therefore, if no message is received from the SKREEM by the PCM, the engine will be disabled and the vehicle immobilized after two seconds of running.

The SKREEM also sends electronic security indicator request messages to the EMIC over the CAN data bus to tell the EMIC how to operate the security indicator. The security indicator request message from the SKREEM tells the EMIC to turn the indicator ON for about three seconds each time the ignition switch is turned to the ON position as a bulb test. After completion of the bulb test, the SKREEM sends security indicator request messages to the EMIC to turn the indicator OFF, turn the indicator ON, or to flash the indicator ON and OFF. If the security indicator flashes or stays ON solid after the bulb test, it signifies a SKIS fault. If the SKREEM detects a system malfunction or the SKIS has become ineffective, the security indicator will stay ON solid. If the SKREEM detects an invalid key or if a key transponder-related fault exists, the security indicator will flash. If the vehicle is equipped with the Customer Learn transponder programming feature, the SKREEM will also send messages to the EMIC to flash the security indicator whenever the Customer Learn programming mode is being utilized .

The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will store fault information in the form of a Diagnostic Trouble Code (DTC) in SKREEM memory if a system malfunction is detected. The hard wired circuits of the SKREEM may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. However, conventional diagnostic methods will not prove conclusive in the diagnosis of the SKREEM or the electronic controls or communication between other modules and devices that provide some features of the SKIS. The most reliable, efficient, and accurate means to diagnose the SKREEM or the electronic controls and communication related to SKREEM operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

Keyless Entry Module: Description and Operation Description DESCRIPTION The Sentry Key REmote Entry Module (SKREEM) (3) (also known as the Sentry Key Immobilizer

Module/SKIM or the Wireless Control Module /WCM) is the primary component of the Sentry Key Immobilizer System (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system and the Tire Pressure Monitor (TPM) system. The SKREEM is located on the right side of the steering column near the ignition lock cylinder housing and is concealed beneath the column shrouds. The molded black plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring (1) that extends from one side. When the SKREEM is properly installed, the antenna ring is oriented around the circumference of the ignition lock cylinder housing.

A single integral connector receptacle (4) is located adjacent to the antenna ring on the SKREEM housing. An integral molded plastic mounting tab (2) on the SKREEM housing has a hole in the center through which a screw passes to secure the unit to the steering column lock housing. The SKREEM is connected to the vehicle electrical system through a single take out and connector of the instrument panel wire harness.

The SKREEM cannot be adjusted or repaired. If ineffective or damaged, the entire SKREEM unit must be replaced.
