Vehicle Theft Security System

Upon failure of proper VTSS/SKIM communication to the PCM, the PCM will shut off fuel after 2 seconds of run time. The engine will not re-crank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again. After 6 consecutive fuel shut-offs, the engine will no longer crank on subsequent key cycles. The failure must be corrected and a valid communication process between the VTSS/SKIM, and the PCM must occur for the engine to crank and start again.

The electronics for the VTSS are part of the BCM. The system is armed when the vehicle is locked using, the power door lock switches, Remote Keyless Entry transmitter and door cylinder lock switches.

For vehicles equipped with SKIS, the doors do not have to be locked to enable the fuel shut off feature. After the vehicle is locked and the last door is closed, the set LED indicator in the top cover will flash quickly for 16 seconds, indicating that arming is in progress. If no monitored systems are activated during this period, the system will arm. After 16 seconds the indicator LED will continue to flash at a slower rate.

This indicates that the system is armed. If the deck lid key cylinder switch is not sensed by the system, the indicator LED will remain lit during the arming process, although the system will still arm. If the indicator LED does not illuminate at all upon door closing, it indicates that the system is not arming.

Passive disarming occurs upon normal vehicle entry by unlocking either door with the ignition key or remote transmitter. This disarming will also halt the alarm once it has been activated.

A tamper alert exists to notify the driver that the VTSS has been activated. This alert consists of 3 horn pulses when the vehicle is disarmed.
