Alarm Module: Description and Operation

Sentry Key Immobilizer (SKIM) Location

SENTRY KEY IMMOBILIZER MODULE(SKIM)

(SKIM) (RF)

(SKIS)

(PCI) (PCM)

The Sentry Key Immobilizer Module contains a Radio Frequency transceiver and a central processing unit, which includes theSentry Key Immobilizer System program logic. The SKIS programming enables the SKIM to program and retain in memory the codes ofat least two, but no more than eight electronically coded Sentry Key transponders. The SKIS programming also enables the SKIM to communicateover the Programmable Communication Interface bus network with the Powertrain Control Module , and/or the DRB III(R) scantool.

eight millimeters (0.31 inches)

The SKIM transmits and receives RF signals through a tuned antenna enclosed within a molded plastic ring formation that is integral to the SKIMhousing. When the SKIM is properly installed on the steering column, the antenna ring is oriented around the circumference of the ignition lockcylinder housing. This antenna ring must be located within of the Sentry Key in order to ensure proper RFcommunication between the SKIM and the Sentry Key transponder.

For added system security, each SKIM is programmed with a unique "Secret Key" code and a security code. The SKIM keeps the "Secret Key"code in memory. The SKIM also sends the "Secret Key" code to each of the programmed Sentry Key transponders. The security code is used bythe assembly plant to access the SKIS for initialization, or by the dealer technician to access the system for service. The SKIM also stores in itsmemory the Vehicle Identification Number (VIN), which it learns through a PCT bus message from the PCM during initialization.

The SKIM and the PCM both use software that includes a rolling code algorithm strategy, which helps to reduce the possibility of unauthorizedSKIS disarming. The rolling code algorithm ensures security by preventing an override of the SKIS through the unauthorized substitution of theSKIM or the PCM. However, the use of this strategy also means that replacement of either the SKIM or the PCM units will require a systeminitialization procedure to restore system operation.

When the ignition switch is turned to the ON or START positions, the SKIM transmits an RF signal to excite the Sentry Key transponder. TheSKIM then listens for a return RF signal from the transponder of the Sentry Key that is inserted in the ignition lock cylinder. If the SKIM receivesan RF signal with valid "Secret Key" and transponder identification codes, the SKIM sends a "valid key" message to the PCM over the PCI bus. Ifthe SKIM receives an invalid RF signal or no response, it sends "invalid key" messages to the PCM. The PCM will enable or disable engineoperation based upon the status of the SKIM messages.

three seconds

one second

The SKIM also sends messages to the Instrument Cluster which controls the VTSS indicator LED. The SKIM sends messages to the InstrumentCluster to turn the LED ON for about when the ignition switch is turned to the ON position as a bulb test. After completion of thebulb test, the SKIM sends bus messages to keep the LED OFF for a duration of about . Then the SKIM sends messages to turn theLED on or OFF based upon the results of the SKIS self-tests. If the VTSS indicator LED comes ON and stays ON after the bulb test, it indicatesthat the SKIM has detected a system malfunction and/or that the SKIS has become inoperative.

If the SKIM detects an invalid key when the ignition switch is turned to the ON position, it sends messages to flash the VTSS indicator LED. TheSKIM can also send messages to flash the LED and to generate a single audible chime tone. These functions serve as an indication to the customerthat the SKIS has been placed in its "Customer Learn" programming mode. See Sentry Key Immobilizer System Transponder Programming formore information on the "Customer Learn" programming mode.
For diagnosis or initialization of the SKIM and the PCM, a DRBIII(R) scan tool and the proper Power-train Diagnostic Procedures are required.

The SKIM cannot be repaired and, if faulty or damaged, the unit must be replaced.

Keyless Entry Module: Description and Operation
REMOTE KEYLESS ENTRY MODULE

(VTSS)

The Remote Keyless Entry module controls the Power Door Locks and the Vehicle Theft Security System . It also wakes up the InstrumentCluster to turn ON the illuminated entry when it senses a signal from the RKE transmitter. The module communicates with other modules via thePCI bus circuit.

The RKE module monitors the Occupant Restraint Controller messages for the purpose of monitoring the deployment of the airbag. Uponreceiving that message along with the verification that the ignition is ON and the vehicle speed is zero, it will provide the "enhanced accidentresponse feature". This feature will cause the module to unlock all doors and the instrument cluster to turn the courtesy lamps ON.

The RKE module communicates with the Powertrain Control Module to receive vehicle speed information to activate the rolling door lock feature,receive the "okay to lock" message, to receive the vehicle information number and receive body style information. Two transmitters are suppliedwith the vehicle but a total of 4 can be programmed to the module. The horn chirp on vehicle lock command is customer programmable.

To limit the amount of battery drain during storage, the module has 3 modes of operation: ship mode, dealer storage mode and customer usagemode. To change from ship mode to dealer storage mode, the DRB III may be used or the ignition switch cycled up to 30 times. To transfer fromdealer storage to customer mode, install the IOD fuse and cycle the ignition switch. To transfer back to dealer storage mode, the DRB III must beused, the IOD fuse removed, and the ignition switch cycled. Sometimes the instrument cluster doesn't transmit a message upon change of the IODfuse. By cycling the ignition, this causes the cluster to transmit the message, thereby ensuring the RKE module has received the most recent IODstatus.

Keyless Entry Module: Description and Operation
REMOTE KEYLESS ENTRY MODULE

(VTSS)

The Remote Keyless Entry module controls the Power Door Locks and the Vehicle Theft Security System . It also wakes up the InstrumentCluster to turn ON the illuminated entry when it senses a signal from the RKE transmitter. The module communicates with other modules via thePCI bus circuit.

The RKE module monitors the Occupant Restraint Controller messages for the purpose of monitoring the deployment of the airbag. Uponreceiving that message along with the verification that the ignition is ON and the vehicle speed is zero, it will provide the "enhanced accidentresponse feature". This feature will cause the module to unlock all doors and the instrument cluster to turn the courtesy lamps ON.

The RKE module communicates with the Powertrain Control Module to receive vehicle speed information to activate the rolling door lock feature,receive the "okay to lock" message, to receive the vehicle information number and receive body style information. Two transmitters are suppliedwith the vehicle but a total of 4 can be programmed to the module. The horn chirp on vehicle lock command is customer programmable.

To limit the amount of battery drain during storage, the module has 3 modes of operation: ship mode, dealer storage mode and customer usagemode. To change from ship mode to dealer storage mode, the DRB III may be used or the ignition switch cycled up to 30 times. To transfer fromdealer storage to customer mode, install the IOD fuse and cycle the ignition switch. To transfer back to dealer storage mode, the DRB III must beused, the IOD fuse removed, and the ignition switch cycled. Sometimes the instrument cluster doesn't transmit a message upon change of the IODfuse. By cycling the ignition, this causes the cluster to transmit the message, thereby ensuring the RKE module has received the most recent IODstatus.

Electronic Brake Control Module: Description and Operation

DESCRIPTION

(CAB) (ABS)

(HCU)

The Controller Antilock Brake is a microprocessor-based device which monitors the Antilock Brake System during normal braking andcontrols it when the vehicle is in an ABS stop. The CAB is mounted to the bottom of the Hydraulic Control Unit . The CAB uses a 25-wayelectrical connector on the vehicle wiring harness. The power source for the CAB is through the ignition switch in the RUN or ON position. The CABis on the PCI bus.

OPERATION

(CAB)

(ABS)

(MIC)

(WSS)

(HCU)

(DTC)

The primary functions of the Controller Antilock Brake are to:1. monitor the Antilock Brake System for proper operation.2. detect wheel locking or wheel slipping tendencies by monitoring the speed of all four wheels of the vehicle.3. control fluid modulation to the wheel brakes while the system is in an ABS mode or the traction control system is activated.4. store diagnostic information.5. provide communication to the DRBIII scan tool while in diagnostic mode.The CAB constantly monitors the ABS for proper operation. If the CAB detects a fault, it will send a message to the Mechanical Instrument Cluster instructing it to turn on the amber ABS warning indicator and disable the antilock braking system. The normal base braking system will remainoperational.The CAB continuously monitors the speed of each wheel through the signals generated by the Wheel Speed Sensors to determine if any wheelis beginning to lock. When a wheel locking tendency is detected, the CAB commands the solenoid coils to actuate. The coils then open and close thevalves in the Hydraulic Control Unit that modulate brake fluid pressure in some or all of the hydraulic circuits. The CAB continues to controlpressure in individual hydraulic circuits until a locking tendency is no longer present.The CAB contains a self-diagnostic program that monitors the ABS for system faults. When a fault is detected, the amber ABS warning indicator isturned on and the fault Diagnostic Trouble Code is then stored in a diagnostic program memory. These DTC's will remain in the CAB memoryeven after the ignition has been turned off. The DTC's can be read and cleared from the CAB memory by a technician using the DRBIII scan tool. Ifnot cleared with the scan tool, the fault occurrence and DTC will be automatically cleared from the CAB memory after the identical fault has not beenseen during the next 3,500 miles of vehicle operation.
