Theft Systems

THEFT SYSTEMS DESCRIPTION AND OPERATION

The theft deterrent system on this vehicle is comprised of two separate systems the vehicle theft deterrent (VTD) system and the content their deterrent (CTD) system. VTD prevents drive away theft by keeping the vehicle from slating. CTD is the vehicle alarm system which discourages unauthorized entry into the vehicle. These system are described and diagnosed separately with this section.

Security Telltale
the SECURITY Telltale on the message center is controlled by both the VTD system and the CTD system. The SECURITY telltale is a part of the reconfigurable message center on the instrument cluster. The SECURITY telltale is controlled by the body control module through the class 2 date line.
- The VTD system contained in the BCM commands the instrument cluster to control the SECURITY Telltale as a malfunction indicator.
- The CTD system also contained in the BCM commands the instrumental cluster to control the indicator only when the ignition switch is OFF. The CTD system uses the SECURITY telltale to identify system status.
