Vehicle Theft Security System - Description

DESCRIPTION

The Sentry Key Immobilizer System (SKIS) is available as a factory-installed option on this vehicle. Vehicles equipped with this option can be readily identified by the illumination of the security indicator in the instrument cluster for about three seconds after the ignition switch is turned to the ON position as a SKIS bulb test.

- Powertrain Control Module - The Powertrain Control Module (PCM) is located in the engine compartment and provides the SKIS engine control logic.
- Security Indicator - A security indicator is integral to the Instrument Cluster
- Sentry Key Immobilizer Module - The Sentry Key Immobilizer Module (SKIM) is integrated into the Body Control Module (BCM).
- Sentry Key Immobilizer Antenna - A antenna ring located around the end of the ignition switch.
- Sentry Key Transponder - The Sentry Key transponder is contained within the Remote Keyless Entry (RKE) transmitter on the ignition key.

Except for the Sentry Key transponders, which rely upon Radio Frequency (RF) communication, hard wired circuitry connects the SKIS components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the SKIS components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
