General Information

INTRODUCTION
The Vehicle Theft Security System (VTSS) is available factory-installed optional equipment for this model. It is a passive system and is designed to protect against whole vehicle theft. The system monitors vehicle doors and deck lid key cylinder for unauthorized operation.

If the vehicle is equipped with VTSS, it will also include the Sentry Key Immobilizer System (SKIS) factory-installed option. Refer to the vehicle owner's manual for more information on the use and operation of the Sentry Key Immobilizer System (SKIS).

SENTRY KEY IMMOBILIZER SYSTEM (SKIS)
The Sentry Key Immobilizer System (SKIS) is designed to provide passive protection against unauthorized vehicle use by preventing the engine from operating while the system is armed. The primary components of this system are the Sentry Key Immobilizer Module (SKIM), the Sentry Key transponder, the Vehicle Theft Security System (VTSS) indicator LED, and the Powertrain Control Module (PCM).

The SKIM is installed on the steering column near the ignition lock cylinder. The transponder is located under the molded rubber cap on the head of the ignition key. The VTSS indicator LED is located in the instrument cluster.

The SKIS includes three valid Sentry Key transponders from the factory, one being a valet key. This is so the customer can self program new keys if one is lost. If the customer wishes, additional non-coded blank Sentry Keys are available. These blank keys can be cut to match a valid ignition key, but the engine will not start unless the key transponder is also programmed to the vehicle. The SKIS will recognize no more than eight valid Sentry Key transponders at any one time.

The SKIS performs a self-test each time the ignition switch is turned to the ON position, and will store Diagnostic Trouble Codes (DTCs) if a system malfunction is detected. The SKIS can be diagnosed, and any stored DTC can be retrieved using a DRB lll scan tool as described in the proper Body Diagnostic Procedures.
