In order to effectively use the wiring diagrams to diagnose and repairDaimlerChrysler Corporation vehicles, it is important to understand all of their features andcharacteristics.Diagrams are arranged such that the power (B+) side of the circuit is placed near the top of thepage, and the ground (B-) side of the circuit is placed near the bottom of the page.All switches, components, and modules are shown in the at rest position with the doors closed andthe key removed from the ignition.Components are shown two ways. A solid line around a component indicates that the component iscomplete. A dashed line around the component indicates that the component is being shown is notcomplete. Incomplete components have a reference number to indicate the page where thecomponent is shown complete.It is important to realize that no attempt is made on the diagrams to represent components andwiring as they appear on the vehicle. For example, a short piece of wire is treated the same as along one. In addition, switches and other components are shown as simply as possible, with regardto function only.Page 192Connector:Name : MODULE-POWERTRAIN CONTROL C2Color : BLACK# of pins : 96Qualifier : (GAS)Pin Description Circuit1 ETC MOTOR (+) K124 20DB/GY2-3-4--Page 169Power Distribution Module: Description and Operation Module-InverterDescriptionDESCRIPTIONThe inverter module is located in the instrument panel.

The ITM uses On-Board Diagnostics (OBD) and can communicate with other electronicmodules 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 theElectroMechanical 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 sidelower edge of the instrument panel. The ITM also communicates with the alarm siren module overa dedicated serial bus circuit.The ITM microprocessor continuously monitors inputs from its on-board motion sensor circuitry aswell as inputs from the EMIC and the alarm siren module. The on-board ITM motion sensorcircuitry transmits ultrasonic signals into the vehicle cabin through a transmit transducer, thenlistens to the returning signals through a receive transducer as they bounce off of objects in thevehicle interior. If an object is moving in the interior, a detection circuit in the ITM senses thismovement through the modulation of the returning ultrasonic signals that occurs due to the Dopplereffect. The motion detect function of the ITM can be disabled by depressing the LOCK button onthe 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 singlesiren 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 tothe EMIC over the CAN data bus and sends an electronic message to the alarm siren module overa dedicated serial bus line to sound the siren. Then the EMIC relays an electronic request messageto the Totally Integrated Power Module (TIPM) to flash the exterior lighting. When the EMIC detectsa breach in the perimeter protection through a hard wired door or liftgate ajar switch input orreceives a hood ajar switch input from the TIPM, it sends an electronic message to the ITM and theITM sends an electronic message to the alarm siren module over a dedicated serial bus line tosound the siren.The ITM also monitors inputs from the alarm siren module for siren battery or siren input/outputcircuit tamper alerts, and for siren battery condition alerts, then sets active and stored DiagnosticTrouble Codes (DTC) for any monitored system faults it detects. An active fault only remains for thecurrent 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 ITMreceives battery current through a fuse in the TIPM, and receives ground through the body wireharness. These connections allow the ITM to remain operational, regardless of the ignition switchposition.The hard wired circuits of the ITM may be diagnosed using conventional diagnostic tools andprocedures. Refer to the appropriate wiring information. However, conventional diagnostic methodswill not prove conclusive in the diagnosis of the ITM or the electronic controls or communicationbetween 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 communicationrelated to ITM operation requires the use of a diagnostic scan tool. Refer to the appropriatediagnostic information.Page 2097. Connect battery and test all affected systems.Wire SplicingSTANDARD PROCEDURE - WIRE SPLICINGWhen splicing a wire, it is important that the correct gage be used as shown in the wiring diagrams.1. Remove one-half (1/2) inch of insulation from each wire that needs to be spliced.2. Place a piece of adhesive lined heat shrink tubing on one side of the wire. Make sure the tubingwill be long enough to cover and seal the entirerepair area.3. Place the strands of wire overlapping each other inside of the splice clip (1).4. Using crimping tool (1), Mopar p/n 05019912AA, crimp the splice clip and wires together.5. Solder (3) the connection (2) together using rosin core type solder (1) only.CAUTION: DO NOT USE ACID CORE SOLDER.DescriptionAlarm Module: Description and Operation DescriptionDESCRIPTIONAn Intrusion Transceiver Module (ITM) is part of the export premium version of the Vehicle TheftAlarm (VTA) in the Vehicle Theft Security System (VTSS). The export premium version of the VTAis only available in vehicles built for certain markets, where the additional features offered by thissystem are required. The ITM is integral to the rear dome lamp housing (1) located in thepassenger compartment, on the lower surface of the headliner near the center of the vehicle. TheITM is designed to provide interior motion detection, and serve as an interface between theElectroMechanical 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 ITMultrasonic transmitter and receiver are visible on the outside of the housing, one each ahead andbehind 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 tothe dome lamp lens. A notch (6) in the housing at the left edge of the lens affords access forservice 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 thecircuit board is connected to the vehicle electrical system by a dedicated take out and connector ofthe 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.Page 201TERMINOLOGYThis is a list of terms and definitions used in the wiring diagrams.LHD -Left Hand Drive Vehicles RHD -Right Hand Drive Vehicles ATX -AutomaticTransmissions-Front Wheel DrivePage 87DiagramsTraction Control Relay: DiagramsComponent ID: 186Component : RELAY-HILL DESCENTConnector:Name : RELAY-HILL DESCENTColor : # of pins :0C6 FUSED B(+) A924 20DG/WTC7 STOP LAMP SWITCH OUTPUT L53 20DG/WTC8 - C9 FUSED B(+) A924 20DG/WTC10 HILL DESCENT RELAY CONTROL B122 20DG/LGPage 1185.

Open hood.2. Disconnect and isolate the battery negative cable.3. Disconnect each of the Totally Integrated Power Module (TIPM) wire harness connectors.4. Remove the TIPM positive cable retaining nut and remove the cable from the stud.5. Depress the three mounting clips to disengage and remove the TIPM housing from its mountingbracket.6. Remove the TIPM from the vehicle.InstallationINSTALLATIONCAUTION: The original Cab Compartment Node (CCN) and Powertrain Control Module (PCM)must be installed and functioning properly prior to powering up the new Totally Integrated PowerModule (TIPM). The TIPM receives vehicle configuration data from the CCN and VehicleIdentification Number information from the PCM. If configuration information becomes lost orcorrupted, the data can be obtained from DealerCONNECT1. Position the TIPM onto the mounting bracket and push down until the mounting clips are fullyseated.Page 64Keyless Entry Module: Description and Operation OperationOPERATIONThe Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless ControlModule/WCM) contains a Radio Frequency (RF) transceiver and a microprocessor. The SKREEMtransmits RF signals to, and receives RF signals from the Sentry Key transponder through a tunedantenna enclosed within the molded plastic antenna ring integral to the SKREEM housing. If thisantenna ring is not mounted properly around the ignition lock cylinder housing, communicationproblems between the SKREEM and the transponder may arise. These communication problemswill result in Sentry Key transponder-related faults.The SKREEM also serves as the Remote Keyless Entry (RKE) RF receiver and, if the vehicle is soequipped, the receiver for the Tire Pressure Monitoring (TPM) system. The SKREEMcommunicates over the Controller Area Network (CAN) data bus with the ElectroMechanicalInstrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), the PowertrainControl 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 SKISthrough the unauthorized substitution of the SKREEM or the PCM. However, the use of thisstrategy also means that replacement of either the SKREEM or the PCM units will require a systeminitialization procedure to restore system operation.The SKREEM retains in memory the ID numbers of any Sentry Key transponder that isprogrammed into it. A maximum of eight Sentry Key transponders can be programmed into theSKREEM. For added system security, each SKREEM is programmed with a unique Secret Keycode. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded tothe transponder of every Sentry Key that is programmed into the SKREEM. Therefore, the SecretKey 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 SentryKey transponder programming procedures. The SKREEM also stores the Vehicle IdentificationNumber (VIN) in its memory, which it learns through a CAN data bus message from the PCMduring SKIS initialization.In the event that a SKREEM replacement is required, the Secret Key code can be transferred tothe new SKREEM from the PCM using the diagnostic scan tool and the SKIS initializationprocedure. Proper completion of the SKIS initialization will allow the existing Sentry Keys to beprogrammed into the new SKREEM so that new keys will not be required. In the event that theoriginal Secret Key code cannot be recovered, SKREEM replacement will also require new SentryKeys. The diagnostic scan tool will alert the technician during the SKIS initialization procedure ifnew Sentry Keys are required.When the key is inserted into the ignition switch and when the ignition switch is turned to the ONposition, the SKREEM transmits an RF signal to excite the transponder in the ignition key. TheSKREEM then waits for an RF signal response from the transponder. If the response receivedidentifies the key as valid, the SKREEM sends an electronic valid key message over the CAN databus. If the response received identifies the key as invalid or if no response is received from the keytransponder, the SKREEM sends an invalid key message. The PCM will enable or disable engineoperation based upon the status of the SKREEM messages. It is important to note that the defaultcondition in the PCM is an invalid key; therefore, if no message is received from the SKREEM bythe 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 CANdata bus to tell the EMIC how to operate the security indicator. The security indicator requestmessage from the SKREEM tells the EMIC to turn the indicator ON for about three seconds eachtime 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 staysON solid after the bulb test, it signifies a SKIS fault. If the SKREEM detects a system malfunctionor the SKIS has become ineffective, the security indicator will stay ON solid. If the SKREEMdetects an invalid key or if a key transponder-related fault exists, the security indicator will flash. Ifthe vehicle is equipped with the Customer Learn transponder programming feature, the SKREEMwill also send messages to the EMIC to flash the security indicator whenever the Customer Learnprogramming mode is being utilized.The SKIS performs a self-test each time the ignition switch is turned to the ON position, and willstore fault information in the form of a Diagnostic Trouble Code (DTC) in SKREEM memory if asystem malfunction is detected. The hard wired circuits of the SKREEM may be diagnosed usingconventional diagnostic tools and procedures. Refer to the appropriate wiring information.However, conventional diagnostic methods will not prove conclusive in the diagnosis of theSKREEM or the electronic controls or communication between other modules and devices thatprovide some features of the SKIS. The most reliable, efficient, and accurate means to diagnosethe SKREEM or the electronic controls and communication related to SKREEM operation requiresthe use of a diagnostic scan tool. Refer to the appropriate diagnostic information.Page 96Electronic Brake Control Module: Service and Repair InstallationINSTALLATIONDue to packaging and limited space it is necessary to install the Antilock Brake Module (ABM) onthe Hydraulic Control Unit (HCU), then install the Integrated Control Unit (ICU) on the vehicle as anassembly.Page 174Power Distribution Module: Service and Repair Module-InverterRemovalREMOVALWARNING: Disable the airbag system before attempting any steering wheel, steering column, orinstrument panel component diagnosis or service.

If the ABMdetects a fault, it will turn on the amber ABS and yellow ESP/BAS indicators and disable the ABSor ESP if so equipped. The normal base braking system will remain operational at that time.The ABM continuously monitors the speed of each wheel through the signals generated by thewheel speed sensors to determine if any wheel is beginning to lock. When a wheel lockingtendency is detected, the ABM commands the ABM solenoid coils to actuate. The coils then openand close the valves in the HCU that modulate brake fluid pressure in some or all of the hydrauliccircuits. The ABM continues to control pressure in individual hydraulic circuits until a lockingtendency is no longer present.Page 9Component Location - 42Page 29Component Location - 29Page 14Component Location - 42Page 42Page 12Component Location - 42Page 81Seat Heater Control Module: Service and Repair InstallationINSTALLATIONCAUTION: The Heated Seat Module mounting tab can be damaged during module removal andinstallation.

The ITM uses On-Board Diagnostics (OBD) and can communicate with other electronicmodules 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 theElectroMechanical 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 sidelower edge of the instrument panel. The ITM also communicates with the alarm siren module overa dedicated serial bus circuit.The ITM microprocessor continuously monitors inputs from its on-board motion sensor circuitry aswell as inputs from the EMIC and the alarm siren module. The on-board ITM motion sensorcircuitry transmits ultrasonic signals into the vehicle cabin through a transmit transducer, thenlistens to the returning signals through a receive transducer as they bounce off of objects in thevehicle interior. If an object is moving in the interior, a detection circuit in the ITM senses thismovement through the modulation of the returning ultrasonic signals that occurs due to the Dopplereffect. The motion detect function of the ITM can be disabled by depressing the LOCK button onthe 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 singlesiren 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 tothe EMIC over the CAN data bus and sends an electronic message to the alarm siren module overa dedicated serial bus line to sound the siren. Then the EMIC relays an electronic request messageto the Totally Integrated Power Module (TIPM) to flash the exterior lighting. When the EMIC detectsa breach in the perimeter protection through a hard wired door or liftgate ajar switch input orreceives a hood ajar switch input from the TIPM, it sends an electronic message to the ITM and theITM sends an electronic message to the alarm siren module over a dedicated serial bus line tosound the siren.The ITM also monitors inputs from the alarm siren module for siren battery or siren input/outputcircuit tamper alerts, and for siren battery condition alerts, then sets active and stored DiagnosticTrouble Codes (DTC) for any monitored system faults it detects. An active fault only remains for thecurrent 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 ITMreceives battery current through a fuse in the TIPM, and receives ground through the body wireharness. These connections allow the ITM to remain operational, regardless of the ignition switchposition.The hard wired circuits of the ITM may be diagnosed using conventional diagnostic tools andprocedures. Refer to the appropriate wiring information. However, conventional diagnostic methodswill not prove conclusive in the diagnosis of the ITM or the electronic controls or communicationbetween 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 communicationrelated to ITM operation requires the use of a diagnostic scan tool. Refer to the appropriatediagnostic information.Page 2097.

Remove one-half (1/2) inch of insulation from each wire that needs to be spliced.2. Place a piece of adhesive lined heat shrink tubing on one side of the wire. Make sure the tubingwill be long enough to cover and seal the entirerepair area.3. Place the strands of wire overlapping each other inside of the splice clip (1).4. Using crimping tool (1), Mopar p/n 05019912AA, crimp the splice clip and wires together.5. Solder (3) the connection (2) together using rosin core type solder (1) only.CAUTION: DO NOT USE ACID CORE SOLDER.DescriptionAlarm Module: Description and Operation DescriptionDESCRIPTIONAn Intrusion Transceiver Module (ITM) is part of the export premium version of the Vehicle TheftAlarm (VTA) in the Vehicle Theft Security System (VTSS). The export premium version of the VTAis only available in vehicles built for certain markets, where the additional features offered by thissystem are required. The ITM is integral to the rear dome lamp housing (1) located in thepassenger compartment, on the lower surface of the headliner near the center of the vehicle. TheITM is designed to provide interior motion detection, and serve as an interface between theElectroMechanical 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 ITMultrasonic transmitter and receiver are visible on the outside of the housing, one each ahead andbehind 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 tothe dome lamp lens. A notch (6) in the housing at the left edge of the lens affords access forservice 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 thecircuit board is connected to the vehicle electrical system by a dedicated take out and connector ofthe 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.Page 201TERMINOLOGYThis is a list of terms and definitions used in the wiring diagrams.LHD -Left Hand Drive Vehicles RHD -Right Hand Drive Vehicles ATX -AutomaticTransmissions-Front Wheel DrivePage 87DiagramsTraction Control Relay: DiagramsComponent ID: 186Component : RELAY-HILL DESCENTConnector:Name : RELAY-HILL DESCENTColor : # of pins :0C6 FUSED B(+) A924 20DG/WTC7 STOP LAMP SWITCH OUTPUT L53 20DG/WTC8 - C9 FUSED B(+) A924 20DG/WTC10 HILL DESCENT RELAY CONTROL B122 20DG/LGPage 1185.

Remove the TIPM from the vehicle.InstallationINSTALLATIONCAUTION: The original Cab Compartment Node (CCN) and Powertrain Control Module (PCM)must be installed and functioning properly prior to powering up the new Totally Integrated PowerModule (TIPM). The TIPM receives vehicle configuration data from the CCN and VehicleIdentification Number information from the PCM. If configuration information becomes lost orcorrupted, the data can be obtained from DealerCONNECT1. Position the TIPM onto the mounting bracket and push down until the mounting clips are fullyseated.Page 64Keyless Entry Module: Description and Operation OperationOPERATIONThe Sentry Key REmote Entry Module (SKREEM) (also known as the Wireless ControlModule/WCM) contains a Radio Frequency (RF) transceiver and a microprocessor. The SKREEMtransmits RF signals to, and receives RF signals from the Sentry Key transponder through a tunedantenna enclosed within the molded plastic antenna ring integral to the SKREEM housing. If thisantenna ring is not mounted properly around the ignition lock cylinder housing, communicationproblems between the SKREEM and the transponder may arise. These communication problemswill result in Sentry Key transponder-related faults.The SKREEM also serves as the Remote Keyless Entry (RKE) RF receiver and, if the vehicle is soequipped, the receiver for the Tire Pressure Monitoring (TPM) system. The SKREEMcommunicates over the Controller Area Network (CAN) data bus with the ElectroMechanicalInstrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), the PowertrainControl 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 SKISthrough the unauthorized substitution of the SKREEM or the PCM. However, the use of thisstrategy also means that replacement of either the SKREEM or the PCM units will require a systeminitialization procedure to restore system operation.The SKREEM retains in memory the ID numbers of any Sentry Key transponder that isprogrammed into it. A maximum of eight Sentry Key transponders can be programmed into theSKREEM. For added system security, each SKREEM is programmed with a unique Secret Keycode. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded tothe transponder of every Sentry Key that is programmed into the SKREEM. Therefore, the SecretKey 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 SentryKey transponder programming procedures. The SKREEM also stores the Vehicle IdentificationNumber (VIN) in its memory, which it learns through a CAN data bus message from the PCMduring SKIS initialization.In the event that a SKREEM replacement is required, the Secret Key code can be transferred tothe new SKREEM from the PCM using the diagnostic scan tool and the SKIS initializationprocedure. Proper completion of the SKIS initialization will allow the existing Sentry Keys to beprogrammed into the new SKREEM so that new keys will not be required. In the event that theoriginal Secret Key code cannot be recovered, SKREEM replacement will also require new SentryKeys. The diagnostic scan tool will alert the technician during the SKIS initialization procedure ifnew Sentry Keys are required.When the key is inserted into the ignition switch and when the ignition switch is turned to the ONposition, the SKREEM transmits an RF signal to excite the transponder in the ignition key. TheSKREEM then waits for an RF signal response from the transponder. If the response receivedidentifies the key as valid, the SKREEM sends an electronic valid key message over the CAN databus. If the response received identifies the key as invalid or if no response is received from the keytransponder, the SKREEM sends an invalid key message. The PCM will enable or disable engineoperation based upon the status of the SKREEM messages. It is important to note that the defaultcondition in the PCM is an invalid key; therefore, if no message is received from the SKREEM bythe 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 CANdata bus to tell the EMIC how to operate the security indicator. The security indicator requestmessage from the SKREEM tells the EMIC to turn the indicator ON for about three seconds eachtime 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 staysON solid after the bulb test, it signifies a SKIS fault. If the SKREEM detects a system malfunctionor the SKIS has become ineffective, the security indicator will stay ON solid. If the SKREEMdetects an invalid key or if a key transponder-related fault exists, the security indicator will flash. Ifthe vehicle is equipped with the Customer Learn transponder programming feature, the SKREEMwill also send messages to the EMIC to flash the security indicator whenever the Customer Learnprogramming mode is being utilized.The SKIS performs a self-test each time the ignition switch is turned to the ON position, and willstore fault information in the form of a Diagnostic Trouble Code (DTC) in SKREEM memory if asystem malfunction is detected. The hard wired circuits of the SKREEM may be diagnosed usingconventional diagnostic tools and procedures. Refer to the appropriate wiring information.However, conventional diagnostic methods will not prove conclusive in the diagnosis of theSKREEM or the electronic controls or communication between other modules and devices thatprovide some features of the SKIS. The most reliable, efficient, and accurate means to diagnosethe SKREEM or the electronic controls and communication related to SKREEM operation requiresthe use of a diagnostic scan tool. Refer to the appropriate diagnostic information.Page 96Electronic Brake Control Module: Service and Repair InstallationINSTALLATIONDue to packaging and limited space it is necessary to install the Antilock Brake Module (ABM) onthe Hydraulic Control Unit (HCU), then install the Integrated Control Unit (ICU) on the vehicle as anassembly.Page 174Power Distribution Module: Service and Repair Module-InverterRemovalREMOVALWARNING: Disable the airbag system before attempting any steering wheel, steering column, orinstrument panel component diagnosis or service.

The SKREEMtransmits RF signals to, and receives RF signals from the Sentry Key transponder through a tunedantenna enclosed within the molded plastic antenna ring integral to the SKREEM housing. If thisantenna ring is not mounted properly around the ignition lock cylinder housing, communicationproblems between the SKREEM and the transponder may arise. These communication problemswill result in Sentry Key transponder-related faults.The SKREEM also serves as the Remote Keyless Entry (RKE) RF receiver and, if the vehicle is soequipped, the receiver for the Tire Pressure Monitoring (TPM) system. The SKREEMcommunicates over the Controller Area Network (CAN) data bus with the ElectroMechanicalInstrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN), the PowertrainControl 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 SKISthrough the unauthorized substitution of the SKREEM or the PCM. However, the use of thisstrategy also means that replacement of either the SKREEM or the PCM units will require a systeminitialization procedure to restore system operation.The SKREEM retains in memory the ID numbers of any Sentry Key transponder that isprogrammed into it. A maximum of eight Sentry Key transponders can be programmed into theSKREEM. For added system security, each SKREEM is programmed with a unique Secret Keycode. This code is stored in memory, sent over the CAN data bus to the PCM, and is encoded tothe transponder of every Sentry Key that is programmed into the SKREEM. Therefore, the SecretKey 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 SentryKey transponder programming procedures. The SKREEM also stores the Vehicle IdentificationNumber (VIN) in its memory, which it learns through a CAN data bus message from the PCMduring SKIS initialization.In the event that a SKREEM replacement is required, the Secret Key code can be transferred tothe new SKREEM from the PCM using the diagnostic scan tool and the SKIS initializationprocedure. Proper completion of the SKIS initialization will allow the existing Sentry Keys to beprogrammed into the new SKREEM so that new keys will not be required. In the event that theoriginal Secret Key code cannot be recovered, SKREEM replacement will also require new SentryKeys. The diagnostic scan tool will alert the technician during the SKIS initialization procedure ifnew Sentry Keys are required.When the key is inserted into the ignition switch and when the ignition switch is turned to the ONposition, the SKREEM transmits an RF signal to excite the transponder in the ignition key. TheSKREEM then waits for an RF signal response from the transponder. If the response receivedidentifies the key as valid, the SKREEM sends an electronic valid key message over the CAN databus. If the response received identifies the key as invalid or if no response is received from the keytransponder, the SKREEM sends an invalid key message. The PCM will enable or disable engineoperation based upon the status of the SKREEM messages. It is important to note that the defaultcondition in the PCM is an invalid key; therefore, if no message is received from the SKREEM bythe 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 CANdata bus to tell the EMIC how to operate the security indicator. The security indicator requestmessage from the SKREEM tells the EMIC to turn the indicator ON for about three seconds eachtime 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 staysON solid after the bulb test, it signifies a SKIS fault. If the SKREEM detects a system malfunctionor the SKIS has become ineffective, the security indicator will stay ON solid. If the SKREEMdetects an invalid key or if a key transponder-related fault exists, the security indicator will flash. Ifthe vehicle is equipped with the Customer Learn transponder programming feature, the SKREEMwill also send messages to the EMIC to flash the security indicator whenever the Customer Learnprogramming mode is being utilized.The SKIS performs a self-test each time the ignition switch is turned to the ON position, and willstore fault information in the form of a Diagnostic Trouble Code (DTC) in SKREEM memory if asystem malfunction is detected. The hard wired circuits of the SKREEM may be diagnosed usingconventional diagnostic tools and procedures. Refer to the appropriate wiring information.However, conventional diagnostic methods will not prove conclusive in the diagnosis of theSKREEM or the electronic controls or communication between other modules and devices thatprovide some features of the SKIS. The most reliable, efficient, and accurate means to diagnosethe SKREEM or the electronic controls and communication related to SKREEM operation requiresthe use of a diagnostic scan tool. Refer to the appropriate diagnostic information.Page 44Page 2081. Disconnect the battery.2. Locate the diode in the harness, and remove the protective covering.3.

If the ABMdetects a fault, it will turn on the amber ABS and yellow ESP/BAS indicators and disable the ABSor ESP if so equipped. The normal base braking system will remain operational at that time.The ABM continuously monitors the speed of each wheel through the signals generated by thewheel speed sensors to determine if any wheel is beginning to lock. When a wheel lockingtendency is detected, the ABM commands the ABM solenoid coils to actuate. The coils then openand close the valves in the HCU that modulate brake fluid pressure in some or all of the hydrauliccircuits. The ABM continues to control pressure in individual hydraulic circuits until a lockingtendency is no longer present.Page 9Component Location - 42Page 29Component Location - 29Page 14Component Location - 42Page 42Page 12Component Location - 42Page 81Seat Heater Control Module: Service and Repair InstallationINSTALLATIONCAUTION: The Heated Seat Module mounting tab can be damaged during module removal andinstallation.

Themodule is grounded to the body at all times through the electrical connector. Inputs to the moduleinclude Local Interface Network (LIN) data bus messages and standard hardwired 12 volt powerand ground. In response to the LIN inputs the heated seat module will control the battery current tothe appropriate heated seat elements.When a heated seat switch LIN data bus signal is received by the heated seat module, the moduleenergizes the selected heated seat element. The Low heat set point is about 38° C (100.4° F), andthe High heat set point is about 42° C (107.6° F).In addition to operating the heated seat elements, the heated seat module sends LED illuminationmessages to the CCN via the LIN data bus. The CCN then sends the LED illumination message tothe accessory switch bank so that the appropriate LEDs are illuminated for any given heating level.Pressing the switch once will select high-level heating. Pressing the switch a second time willselect low-level heating. Pressing the switch a third time will shut the heating elements off.If the heated seat module detects a heated seat element OPEN or SHORT circuit, it will record andstore the appropriate diagnostic trouble code (DTC).DescriptionKeyless Entry Module: Description and Operation DescriptionDESCRIPTIONThe Sentry Key REmote Entry Module (SKREEM) (3) is sometimes referred to as the WirelessControl Module (WCM). The SKREEM is the primary component of the Sentry Key ImmobilizerSystem (SKIS). It is also the receiver for the Remote Keyless Entry (RKE) system and the TirePressure Monitor (TPM) system. The SKREEM is located on the right side of the steering columnnear the ignition lock cylinder housing and is concealed beneath the column shrouds. The moldedblack plastic housing for the SKREEM has an integral molded plastic halo-like antenna ring (1) thatextends from one side. When the SKREEM is properly installed, the antenna ring is orientedaround the circumference of the ignition lock cylinder housing.A single integral connector receptacle (4) is located adjacent to the antenna ring on the SKREEMhousing.
