Anti-Theft System

NOTE: Anti-theft system may also be referred to as Vehicle Theft Security System (VTSS).

Anti-theft system monitors vehicle doors, ignition switch, power door locks and door key cylinder switches to determine if alarm should trigger and prevent engine from starting. When an unauthorized entry is detected, system responds by sounding horn, flashing headlights, flashing taillights and flashing parking lights for 3 minutes. BCM also sends a message to PCM to prevent engine from starting.

System can be armed by using remote keyless entry transmitter or by pressing power door lock switch when exiting vehicle. Anti-theft system uses a security light located above instrument cluster to indicate when system is armed. System can be disarmed by unlocking a front door, liftgate or by remote keyless entry transmitter. If vehicle is tampered with anti-theft indicator light will change from a slow steady flash to a quick double flash and horn chirp will not function when unlock command is received from remote keyless entry transmitter.

Panic alert mode flashes headlight and taillights, pulses horn and disarms alarm. Driver can exit panic alert mode by either pushing panic button on remote keyless entry transmitter or by driving vehicle above 15 MPH.

Whenever BCM is replaced, anti-theft system must be enabled by unlocking doors with key one time or by using scan tool. This allows BCM to see that the vehicle is equipped with an anti-theft system.
