Vehicle Theft Security System - Operation

OPERATION

When the Vehicle Theft Security System (VTSS) is armed, there is no communication to the PCM, the PCM will shut off fuel after two seconds of run time. The engine will not recrank on the key cycle that the failure occurred, a full key down sequence must be performed for the engine to crank again.

After one consecutive fuel shut off, the engine will no longer crank on subsequent key cycles. The failure must be corrected and a valid communication process between the BCM 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 these methods:

- Power door lock switches (with any door ajar)
- Remote Keyless Entry (RKE) Lock Button
- RKE transmitter

After the vehicle is locked and the last door is closed, the VTSS lamp in the review mirror will flash quickly for 16 seconds, indicating that arming is in progress. If the trunk/hood is open or a fault is detected: ignition switch, door entry switches or key cylinder switch, then the VTSS lamp will remain solid during the arming process and the system will still arm. If no door is opened or the ignition does not change to run during this period, the system will arm. When the system is armed, the VTSS lamp will flash at a slower rate. If the VTSS lamp does not illuminate at all upon the last door closing, it indicates that the system is not arming.

The system is disarmed when the vehicle is unlocked using these methods:

- RKE Unlock Button
- Door cylinder Unlock switch

NOTE: The VTSS will not disarm with the key in the ignition (No SKIM).

Disarming will halt the alarm if it is activated. A tamper alert exist to notify the driver that the VTSS had been activated. This alert consist of the VTSS lamp flashing two times quickly until the vehicle is disarmed. When the vehicle is disarmed, the horn will pulse 3 times.

NOTE: The VTSS will not disarm by opening the vehicle from the inside door handle.

If the VTSS is triggered, the horn will pulse, fog lamps/park lamps will flash and the VTSS warning lamp will flash (alarming) for three minutes. If a trigger is still active after three minutes, then the alarm will continue for an additional 15 minutes without the horn.

The VTSS monitoring portion of the system is split into three sections:

- Engine
- Passenger compartment
- Trunk compartment

If a malfunction occurs in the engine or trunk compartment, the passenger compartment would still arm and function normally.
