SYSTEM

The Vehicle Theft/Security System (VTSS) is
designed to protect against whole vehicle theft. The
system monitors the vehicle doors and ignition for
unauthorized operation.
The VTSS activates:
• Sounding of the horn
• Flashing of the park lamps
• Flashing of the head lamps
The Remote Keyless Entry (RKE) has 1 mode of
operation, CUSTOMER USAGE mode. The cus-
tomer usage mode provides full functionality of the
module and is the mode in which the RKE module
should be operating when used by the customer.
DESCRIPTION - SENTRY KEY IMMOBILIZER
SYSTEM (SKIS)
The Sentry Key Immobilizer System (SKIS) is
designed to provide passive protection against unau-
thorized vehicle use by preventing the engine from
operating while the system is armed. The primary
components of this system are the Sentry Key Immo-
bilizer Module (SKIM), the Sentry Key transponder,
the Vehicle Theft/Security System (VTSS) indicator
LED, and the Powertrain Control Module (PCM).

the ignition lock cylinder. The transponder is located
under the molded rubber cap on the head of the igni-
tion key. The VTSS indicator LED is located in the
instrument cluster.
DESCRIPTION - SENTRY KEY IMMOBILIZER
MODULE (SKIM)
The Sentry Key Immobilizer Module (SKIM) con-
tains a Radio Frequency (RF) transceiver and a cen-
tral processing unit, which includes the Sentry Key
Immobilizer System (SKIS) program logic. The SKIS
programming enables the SKIM to program and
retain in memory the codes of at least two, but no
more than eight electronically coded Sentry Key
transponders. The SKIS programming also enables
the SKIM to communicate over the Programmable
Communication Interface (PCI) bus network with the
Powertrain Control Module
DRBIII scan tool.
