Alarm Module: Description and Operation Description DESCRIPTION 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 housing has two integral mounts (2) that secure the module, and an integral connector receptacle (3). Concealed within the molded plastic housing is the circuitry of the module, which includes a microprocessor.

The intrusion module (2) is secured within a cavity on the right side of a molded plastic intermediate step assembly (1) located on the rear floor panel under the second row seat cushion by two slots and two latch features integral to the floor of the step cavity The module is concealed beneath a carpeted trim cover secured by hook and loop fasteners over the step cavity. The inboard side of this step cavity also contains the satellite radio receiver (4) on vehicles that are so equipped. The module is connected to the vehicle electrical system by a take out and connector of the body wire harness (3).

The intrusion module unit cannot be adjusted or repaired and, if ineffective or damaged, it must be replaced.

Alarm Module: Description and Operation Operation OPERATION The microprocessor in the intrusion module contains the motion detection logic circuits and controls

all of the features of the premium version of the Vehicle Theft Alarm (VTA). The module uses On-Board Diagnostics (OBD) and can communicate with other 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 module to communicate with the Front Control Module (FCM) and the ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The module also communicates with the alarm siren over a dedicated serial bus circuit.

The intrusion module microprocessor continuously monitors inputs from the intrusion sensor transmitter and receiver as well as inputs from the EMIC and the alarm siren module. The module energizes the intrusion sensor transmitter, which transmits ultrasonic signals into the vehicle cabin through a transmit transducer, then monitors the current draw of the transmitter to detect problems with the transmitter and transmitter circuits. The module also energizes the intrusion sensor receiver, which listens to the ultrasonic signals through a receive transducer as they bounce off of objects in the vehicle interior, then monitors the current draw of the receiver for data signals and to detect problems with the receiver and receiver circuits. If an object is moving in the interior, a detection circuit in the module senses this movement through the modulation of the returning data signals from the receiver.

If movement is detected, the intrusion module sends an electronic message to the FCM over the CAN data bus to flash the exterior lighting and sends another message to the alarm siren module over the dedicated serial bus line to sound the siren. When the EMIC or FCM detect a breach in the perimeter protection through a door, liftgate, flip-up glass, or hood ajar switch input, they send an electronic message to the intrusion module and the module sends a message to the FCM to flash the exterior lighting and a message to the alarm siren module to sound the siren. The module also monitors message inputs from the alarm siren module for siren battery or siren input/output circuit tamper alerts, and 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 module. If a fault does not recur for 50 ignition cycles, the module will automatically erase the stored DTC.

The intrusion module receives battery voltage on a fused B(+) circuit through a fuse in the Junction Block (JB), and is grounded at all times through a hard wired remote ground point. These connections allow the module to remain operational, regardless of the ignition switch position.

The hard wired circuits of the intrusion module 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 intrusion module 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 intrusion module or the electronic controls and communication related to intrusion module operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.

Ignition Shut Down Relay (For Antitheft): Description and Operation Operation PCM Output PCM OUTPUT The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With

certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The ground circuit for the coil within the ASD relay is controlled by the Powertrain Control Module

(PCM). The PCM operates the ASD relay by switching its ground circuit on and off. The ASD relay will be shut-down, meaning the 12-volt power supply to the ASD relay will be

de-activated by the PCM if:

- The ignition key is left in the ON position. This is if the engine has not been running for approximately 1.8 seconds.

- There is a crankshaft position sensor signal to the PCM that is lower than pre-determined values. ASD Sense - PCM Input ASD SENSE - PCM INPUT A 12 volt signal at this input indicates to the PCM that the ASD has been activated. The relay is

used to connect the oxygen sensor heater element, ignition coil and fuel injectors to 12 volt + power supply.

This input is used only to sense that the ASD relay is energized. If the Powertrain Control Module (PCM) does not see 12 volts at this input when the ASD should be activated, it will set a Diagnostic Trouble Code (DTC).

Keyless Entry Module: Description and Operation Description DESCRIPTION The Sentry Key REmote Entry Module (SKREEM) (4) is sometimes referred to as the Wireless

Control Module (WCM). The SKREEM 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 in the instrument panel, just to the right of the steering column near the ignition lock cylinder housing and is concealed beneath the instrument panel trim. The molded black plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring (3) 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 (1) is located next 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 instrument panel. 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. 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. On vehicles equipped with an export premium version of the Sentry Key Immobilizer System (SKIS), the SKREEM also serves as a translator module and has bi-directional communication with the shaft lock module over a dedicated serial bus.

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 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 to the PCM 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 to the PCM. 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.

Parking Assist Control Module: Description and Operation Description

DESCRIPTION The Park Assist Module (5) is secured within a cavity on the left side of a molded plastic

intermediate step assembly (4) located on the rear floor panel (3) under the second row seat cushion. The module is concealed beneath a carpeted trim cover secured by hook and loop fasteners over the step cavity. The inboard side of this cavity also contains the Final Drive Control Module (FDCM) (1) on vehicles that are so equipped. Both modules are connected to the vehicle electrical system through dedicated take outs and connectors of the underbody wire harness (2).

Concealed within the molded plastic park assist module housing (1) is a microprocessor and the other electronic circuitry of the module. The module housing is sealed to enclose and protect the internal electronic circuitry. The module software is flash programmable.

There are four mounting tabs (2 and 3) integral to the module housing that secure the module through two slots and two latch features integral to the floor of the step cavity. Two connector receptacles (4) containing terminal pins that connect the module to the vehicle electrical system are integral to the one side of the housing. One of the receptacles is utilized in vehicles equipped with only the rear park assist system, while both receptacles are used on vehicles equipped with both the front and rear park assist systems.

The park assist module cannot be adjusted or repaired and, if damaged or ineffective, it must be replaced.

Parking Assist Control Module: Description and Operation Operation OPERATION The microprocessor in the park assist module contains the park assist system logic circuits. The

module uses On-Board Diagnostics (OBD) and can communicate with other electronic modules in the vehicle as well as with the diagnostic scan tool using the Controller Area Network (CAN) data bus. This method of communication is also used for park assist system diagnosis and testing through the 16-way data link connector located on the driver side lower edge of the instrument panel.

The module provides voltage to each of the park assist sensors located behind the front and rear bumper fascias and to the front and rear park assist displays. The module then monitors return inputs from each of the sensors and the displays on dedicated hard wired data communication circuits. The sensor inputs allow the module to determine when an obstacle is in the front or rear path of the vehicle and enables the module to calculate the relative location of the obstacle, and whether the distance to that obstacle is increasing or decreasing.

Pre-programmed decision algorithms and calibrations allow the module microprocessor to determine the appropriate park assist system outputs based upon the inputs received from the park assist sensors and electronic messages received from other modules in the vehicle over the CAN data bus. When the programmed conditions are met the module sends electronic messages to the park assist displays over a dedicated serial bus to obtain the proper park assist system visual and audible outputs. The module also broadcasts electronic messages over the CAN data bus to enable the other electronic features of the park assist system.

The park assist module microprocessor continuously monitors all of the park assist system electrical circuits and components to determine the system readiness. If the module detects a monitored system fault, it sets a Diagnostic Trouble Code (DTC) and sends the appropriate electronic messages to the instrument cluster over the CAN data bus to control operation of certain park assist system audible warnings and textual messages displayed in the reconfigurable display of the instrument cluster.

The park assist module receives battery current on a fused ignition switch output (run-start) circuit through a fuse in the Junction Block (JB). The module receives ground through a ground circuit and take out of the underbody wire harness. These connections allow the module to be operational whenever the ignition switch is in the START or ON positions.

The hard wired circuits between components related to the park assist module may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

However, conventional diagnostic methods will not prove conclusive in the diagnosis of the park assist module or the electronic controls or communication between modules and other devices that provide some features of the park assist system. The most reliable, efficient, and accurate means to diagnose the park assist module or the electronic controls and communication related to park assist module operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
