Alarm Module: Description and Operation
SENTRY KEY IMMOBILIZER MODULE

Sentry Key Immobilizer Module

(SKIM) (RF)

(SKIS)

(PCI) (PCM)

The Sentry Key Immobilizer Module (Fig.10) contains a Radio Frequency transceiver and a central processing unit, which includesthe Sentry Key Immobilizer System program logic. The SKIS programming enables the SKIM to program and retain in memory the codesof at least two, but no more than eight electronically coded Sentry Key transponders. The SKIS programming also enables the SKIM tocommunicate over the Programmable Communication Interface bus network with the Powertrain Control Module , and/or the DRBIII scan tool.

Sentry Key Immobilizer Module Location

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.

300M Special V6-3.5L VIN G (2002)

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 and sends the code over the PCI bus to the PCM, which also keeps this code in its memory. The SKIM also sends the "SecretKey" code to each of the programmed Sentry Key transponders. The security code is used by the assembly plant to access the SKIS forinitialization, or by the dealer technician to access the system for service. The SKIM also stores in its memory the Vehicle Identification Number , which it learns through a PCI bus message from the PCM during initialization.(VIN)

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

The SKIM also sends messages to the BCM which controls the VTSS indicator LED. The SKIM sends messages to the BCM to turn the LED onfor about when the ignition switch is turned to the ON position as a bulb test. After completion of the bulb test, the SKIM sends busmessages to keep the LED OFF for a duration of about one second. Then the SKIM sends messages to turn the LED ON or OFF based upon theresults of the SKIS self-tests. If the VTSS indicator LED comes on and stays on after the bulb test, it indicates that the SKIM has detected a systemmalfunction 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 in thissection for more information on the "Customer Learn" programming mode.

For diagnosis or initialization of the SKIM and the PCM, a DRB III scan tool and the proper Body Diagnostic Procedures are required. The SKIMcannot be repaired and, if faulty or damaged, the unit must be replaced.

There are three versions of the Memory Seat Module . The standard version of the MSM is used on vehicles that are not equipped with theoptional heated seat system. A Memory Heated Seat/Mirror Module is used on vehicles that are equipped with the heated seat systemoption. A third module, the Heated Seat Module , does not have any memory system capabilities and is only available on vehicles that areequipped with an optional heated seat system. Refer to Heated Seats for more information on the heated seat system option.

For diagnosis of the MSM, MHSMM or the PCI data bus, a DRB III scan tool and the proper Diagnostic Procedures are recommended. The MSMor MHSM cannot be adjusted or repaired and, if faulty or damaged, it must be replaced.

(BCM) (PCM)

The MSM receives hard wired inputs from the power seat switch and the potentiometers on each of the driver side power seat motors. The MSMreceives messages over the PCI data bus from the Body Control Module and the Powertrain Control Module (vehicle speedstatus). The programming in the MSM allows it to process the information from these inputs and send control outputs to each of the driver sidepower seat motors. The MSM will prevent the seat memory recall function from being initiated if the driver side seat belt is buckled, if thetransmission gear selector lever is not in the Park or Neutral positions, or if the vehicle is moving. The module also controls the seat heaters and isconnected to the seat harness by four connectors.

All three modules are packaged in an identical molded plastic housing which is mounted on a bracket that is located between the power seat trackand the seat cushion frame under the forward edge of the driver side front seat cushion. The MSM or MHSMM is used to control all of the driverside power seat memory functions and features. The MSM or MHSM contains a central processing unit and interfaces with other electronicmodules in the vehicle on the Programmable Communications Interface data bus network.(PCI)

Intermittent and Poor Connections
INTERMITTENT AND POOR CONNECTIONS

Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a sticking component or relay tocause a problem. Before condemning a component or wiring assembly, check the following items.-

Connectors are fully seated

- Spread terminals, or terminal push out

- Terminals in the wiring assembly are fully seated into the connector/component and locked into position

- Dirt or corrosion on the terminals. Any amount of corrosion or dirt could cause an intermittent problem

- Damaged connector/component casing exposing the item to dirt or moisture

- Wire insulation that has rubbed through causing a short to ground

- Some or all of the wiring strands broken inside of the insulation

- Wiring broken inside of the insulation

Troubleshooting Tests

Fig.6 Electrostatic Discharge Symbol

STANDARD PROCEDURE - ELECTROSTATIC DISCHARGE (ESD) SENSITIVE DEVICES

All ESD sensitive components are solid state and a symbol (Fig. 6) is used to indicate this. When handling any component with this symbol, complywith the following procedures to reduce the possibility of electrostatic charge build up on the body and inadvertent discharge into the component. If itis not known whether the part is ESD sensitive, assume that it is.

1. Always touch a known good ground before handling the part. This should be repeated while handling the part and more frequently after sliding
across a seat, sitting down from a standing position, or walking a distance.

2. Avoid touching electrical terminals of the part, unless instructed to do so by a written procedure.3. When using a voltmeter, be sure to connect the ground lead first.4. Do not remove the part form it's protective packing until it is time to install the part.5. Before removing the part from it's package, ground the package to a known good ground on the vehicle.

Fig.8 Testing For Continuity

2. Connect one lead of the ohmmeter to one side of the circuit being tested (Fig. 8).3. Connect the other lead to the other end of the circuit being tested. Low or no resistance means good continuity.

STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND

1. Remove the fuse and disconnect all items involved with the fuse.2. Connect a test light or a voltmeter across the terminals of the fuse.3. Starting at the fuse block, wiggle the wiring harness about apart and watch the voltmeter/test lamp.6 - 8 inches

4. If the voltmeter registers voltage or the test lamp glows, there is a short to ground in that general area of the wiring harness.

STANDARD PROCEDURE - TESTING FOR A SHORT TO GROUND ON FUSES POWERING SEVERAL LOADS

1. Refer to the wiring diagrams and disconnect or isolate all items on the suspected fused circuits.2. Replace the blown fuse.3. Supply power to the fuse by turning ON the ignition switch or re-connecting the battery.4. Start connecting or energizing the items in the fuse circuit one at a time. When the fuse blows the circuit with the short to ground has been isolated.

Troubleshooting Tools

When diagnosing a problem in an electrical circuit there are several common tools necessary. These tools are listed and explained below.

Jumper Wire

This is a test wire used to connect two points of a circuit. It can be used to bypass an open in a circuit.

WARNING: NEVER USE A JUMPER WIRE ACROSS A LOAD, SUCH AS A MOTOR, CONNECTED BETWEEN A BATTERYFEED AND GROUND.

Voltmeter

Used to check for voltage on a circuit. Always connect the black lead to a known good ground and the red lead to the positive side of the circuit.

CAUTION:

Most of the electrical components used in today's vehicles are Solid State. When checking voltages in these circuits, use a meter witha or greater impedance rating.10 mega-ohm

1. Connect the positive lead of the voltmeter to the side of the circuit closest to the battery (Fig. 9).2. Connect the other lead of the voltmeter to the other side of the switch, component or circuit.3. Operate the item.4. The voltmeter will show the difference in voltage between the two points.

Ohmmeter

Used to check the resistance between two points of a circuit. Low or no resistance in a circuit means good continuity.

CAUTION:

10 mega-ohm

Most of the electrical components used in today's vehicles are Solid State. When checking resistance in these circuits use a meterwith a or greater impedance rating. In addition, make sure the power is disconnected from the circuit. Circuits that are powered upby the vehicle's electrical system can cause damage to the equipment and provide false readings.

Fig. 4 Probing Tool

Probing Tools

These tools are used for probing terminals in connectors (Fig. 4). Select the proper size tool from Special Tool Package 6807, and insert it into theterminal being tested. Use the other end of the tool to insert the meter probe.

Troubleshooting Wiring Problems

When troubleshooting wiring problems, there are six steps which can aid in the procedure. The steps are listed and explained below. Always check fornonfactory items added to the vehicle before doing any diagnosis. If the vehicle is equipped with these items, disconnect them to verify these add-onitems are not the cause of the problem.

1. Verify the problem.2. Verify any related symptoms. Do this by performing operational checks on components that are in the same circuit. Refer to the wiring diagrams. 3. Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring, and where the
diagnosis will continue.

4. Isolate the problem area.5. Repair the problem.6. Verify proper operation. For this step, check for proper operation of all items on the repaired circuit.
