Vehicle Theft Security System
Vehicle Theft Security System
Description
The vehicle theft security system is designed to protect against whole vehicle theft and provide passive protection against unauthorized vehicle start up. If an invalid key is used to start the vehicle, the engine will cut out after two (2) seconds of running. In subsequent years there were various modules controlling the VTSS system. On this model, the wireless communication module has been replaced with the wireless ignition node to control the VTSS system. The remote keyless entry transmitter has been replaced with the fob integrated key. The primary components of the system are the wireless ignition node, fob integrated key, and the PCM. The WIN is mounted on the instrument panel to the right of the steering column. The indicator light is located in the instrument cluster or cabin compartment node. The system monitors vehicle doors, ignition and liftgate action for any unauthorized operation. The alarm activates:
• Sounding of the horn.
• Flashing of the hazard lamps.
• An engine kill feature.
Operation
Upon failure of proper operation of the VTSS, the WIN will communicate to the PCM, and the PCM will shut off fuel after two 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 six 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 WIN and the PCM must occur for the engine to crank and start again.
The electronics for the VTSS are part of the CCN. The system is armed when the vehicle is locked using the:
• Power door lock switches
• FOBIK
After the vehicle is locked and the last door is closed, the set light emitting diode indicator in the CCN 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.
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 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 had been activated. This alert consists of 3 horn pulses when the vehicle is disarmed.
If the VTSS is triggered, the horn will pulse, hazard lamps will flash, and the VTSS warning lamp will flash. The VTSS monitors the passenger compartment. If a malfunction occurs in the engine compartment, the passenger compartment would still arm and function normally.
• System will not arm if passenger compartment is not secure.
Arming The VTSS - Method A
- With the key removed from the ignition lock and any door open, excluding liftgate, actuate one of the following:
• Power door lock button to LOCK,
• FOBIK transmitter LOCK button
- Close all opened doors. Liftgate can remain open.
- After the last door is closed, an arming time-out period of sixteen seconds will start, then the VTSS will become armed.
Arming The VTSS - Method B
Actuating the FOBIK lock button, with the doors closed and the ignition locked, will begin the arming time-out period. If method A, 16 second time-out sequence was in process when method B was actuated, the 16 second time-out will restart from the time of the second actuation.
If the security lamp does not illuminate at all upon final door closure, it indicates that the system is not arming.
The current VTSS status armed or disarmed shall be maintained in memory to prevent battery disconnects from disarming the system.
Triggering The VTSS
After the VTSS is armed, the following actions will trigger the alarm:
• Opening any door (liftgate - only if opening via liftgate button on key fob).
• Turning the ignition to the RUN position.
The red indicator LED will trigger and engine will continue to run if the vehicle is equipped with VTSS and the proper key is used to start the vehicle.
Remote Keyless Entry System
The RKE system is now controlled by the WIN. The FOBIK will transmit to the WIN. The WIN includes keys from the factory which are pre-programmed. Each WIN will recognize a maximum of eight FOBIK Keys. If the customer would like to own additional keys other than those provided with the vehicle, they can be purchased from any authorized dealer. These keys must be programmed to the WIN on the vehicle in order for the system to recognize them as valid keys. This can be done by the dealer with a scan tool or by a customer if this feature is available in their market and they have two (2) valid keys already available to them. Refer to the service procedures portion of this system for additional details. The WIN performs a self-test each time the ignition switch is turned to the ON position and will store DTCs if a system malfunction is detected. The WIN can be diagnosed and any stored DTCs can be retrieved using a scan tool as described in the appropriate area of the diagnostic procedures information.
