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

The security indicator on the instrument cluster is controlled by both the VTD system and the CTD system. The security indicator is displayed on the instrument cluster. The indicator is controlled by the instrument cluster when commanded by the theft deterrent controller module via the class 2 serial data line.

The keyless entry system functions interact with the content theft deterrent system but is diagnosed as a stand-alone system. Refer to Keyless Entry System Description and Operation in Keyless Entry.

The theft deterrent system does not interact with radio theft lock equipped vehicles. Radio theft lock is diagnosed as a stand-alone system. Refer to Radio/Audio System Description and Operation in Entertainment.
