SKREEM/SKIM VERIFICATION

For a complete wiring diagram Refer to Section 8W.

Diagnostic Test

SKREEM/SKIM VERIFICATION

NOTE: When entering the PIN, care should be taken because the SKREEM will only allow 3 consecutive
attempts to enter the correct PIN. If 3 consecutive incorrect PIN’s are entered the SKREEM will Lock Out the
scan tool. To exit Lock Mode, the ignition key must remain the Run position for I hour. All accessories must
be off. A battery charger connected to the battery during this time period is recommended.

NOTE: On vehicles equipped with a premium Tire Pressure Monitoring (TPM) system, when the SKREEM
and/or the spare tire pressure sensor is replaced with a new unit, a diagnostic scan tool MUST be used to
run a routine that allows the SKREEM to be programmed with the ID number and location of the spare tire
pressure sensor mounted in the wheel of the spare tire. Follow the programming steps outlined in the diag-
nostic scan tool for “Learn Spare Tire Sensor ID” under “Miscellaneous Functions” for the “WCM/Wireless
Control Module” menu item as appropriate. In addition, if the SKREEM is replaced, the spare tire must be
dismounted from its wheel to access and note the ID number on the spare tire pressure sensor so that the
ID code for that sensor can be programmed into the new SKREEM.

1. Reconnect the previously disconnected components and connectors.

2. Obtain the vehicle’s unique Personal Identification Number (PIN) assigned to it’s original SKREEM. This num-
ber can be obtained from the vehicle invoice or from the DaimlerChrysler Customer Center (Phone 1-800-992-
1997).

NOTE: If the PCM and the SKREEM are replaced at the same time, program the PCM VIN into the PCM first.
All vehicle keys will then need to be replaced and programmed to the new SKREEM.

4. With the scan tool, select Miscellaneous Functions, WCM/Wireless Control Module. Then select the desired
procedure and follow the display on the scan tool.

5. If the vehicle is equipped with Tire Pressure Monitoring System program the Palcard Pressure Values into the
WCM/SKREEM.

6. Ensure all the customer’s key have been programmed into the new module if necessary.

7. With the scan tool, ease all DTCs. Perform 5 ignition key cycles, leaving the key on for at least 90 seconds
per cycle.

8. With the scan tool, read SKREEM DTC(s).

NOTE: During PCM/ECM replacement, ensure to transfer the secret key information from the SKREEM to the
new PCM. The PCM stores this information only. If the SKREEM ever needs to be replaced, the secret key
information can be retrieved from the PCM and then transferred to the SKREEM for security use.

10.

NOTE: If this vehicle is equipped with a Steering Column Lock Module, it must be replaced along with the
SKREEM.

Are there any SKREEM DTC(s) present?

Yes

>> Repair not complete, refer to the appropriate symptom.

>> Repair is complete.

VEHICLE THEFT SECURITY - SERVICE INFORMATION

DESCRIPTION

The Vehicle Theft Security System (VTSS) is comprised of two primary subsystems: Vehicle Theft Alarm (VTA) and
Sentry Key Immobilizer System (SKIS). The VTA is an active system that provides visual and audible responses as
deterrents to and warnings of unauthorized vehicle tampering. The SKIS is a passive system that effectively immo-
bilizes the vehicle against unauthorized operation. Following are paragraphs which describe these subsystems of
the VTSS.

Certain functions and features of the VTSS rely upon resources shared with or controlled by other electronic mod-
ules in the vehicle over the Controller Area Network (CAN) data bus. Other modules that may affect VTSS operation
are:

•

ElectroMechanical Instrument Cluster (EMIC) - Also sometimes referred to as the Cab Compartment Node
(CCN). Driver and passenger front and rear doors, and liftgate ajar switch status. VTA system logic. Security
indicator control. (Refer to 8 - ELECTRICAL/INSTRUMENT CLUSTER - DESCRIPTION).

•

Powertrain Control Module (PCM) - SKIS engine control logic. (Refer to 8 - ELECTRICAL/ELECTRONIC
CONTROL MODULES/POWERTRAIN CONTROL MODULE - DESCRIPTION).

•

Steering Control Module (SCM) - (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/STEER-
ING CONTROL MODULE - DESCRIPTION).

•

Totally Integrated Power Module (TIPM) - Hood ajar switch status (export only). Exterior lighting system and
horn system control. (Refer to 8 - ELECTRICAL/POWER DISTRIBUTION/POWER DISTRIBUTION CENTER -
DESCRIPTION).

Except for the Sentry Key transponders, which rely upon Radio Frequency (RF) communication, hard wired circuitry
connects the VTA and SKIS components to the electrical system of the vehicle.

VEHICLE THEFT ALARM

The VTA is available in two different configurations, one is designed for vehicles manufactured for sale in North
America; while the other is designed for vehicles manufactured for sale in markets outside of North America. In
addition, the VTA for export is available in two versions: base and premium. All vehicles equipped with VTA are also
equipped with the Remote Keyless Entry (RKE) system and the Sentry Key Immobilizer System (SKIS), regardless
of their market destination.

The North American and export base version of the VTA system provide perimeter vehicle protection by monitoring
the vehicle doors, the ignition switch, the liftgate, the liftgate flip-up glass and, for vehicles built for certain markets
where it is required equipment, the hood. If unauthorized vehicle use or tampering is detected, these systems
respond by pulsing the vehicle horn as an audible deterrent and flashing certain exterior lamps as a visual deterrent.

The export premium version of the VTA system is only available in vehicles manufactured for sale in certain markets
where it is required equipment. The export premium version of the VTA provides the same perimeter protection
features as the base version, but adds interior vehicle intrusion protection. The export premium VTA also supple-
ments the pulsing horn feature of the base version with a siren as the audible deterrent, while retaining the flashing
exterior lamps as the visual deterrent.

The VTA includes the following major components, which are described in further detail elsewhere in this service
information:

•

Door Ajar Switches - A door ajar switch is integral to the door latch mechanism of each front and rear door.

•

Hood Ajar Switch - A hood ajar switch is located in a bracket on the left rear side of the engine compartment,
near the shock tower of vehicles built for sale in certain export markets where it is required equipment.

•

Intrusion Module - An intrusion module is located underneath the instrument panel upper panel, just to the
right centerline of the instrument panel base, next to the remote compass module, of vehicles built for sale in
certain export markets where it is required equipment.

•

Intrusion Sensor Receiver - An intrusion sensor receiver is located behind and mounted to the right A-Pillar
trim panel of vehicles built for sale in certain export markets where it is required equipment.

•

Intrusion Sensor Transmitter - An intrusion sensor transmitter is located behind and mounted to the left
Upper C-Pillar trim panel of vehicles built for sale in certain export markets where it is required equipment.

•

Liftgate Ajar Switch - A liftgate ajar switch is integral to the latch for the liftgate in the vehicle.

•

Security Indicator - A security indicator is integral to the ElectroMechanical Instrument Cluster (EMIC), some-
times referred to as the Cab Compartment Node (CCN).
