Theft Deterrent System
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 may be thought of as a vehicle Immobilizer system, preventing 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. For VTD description, refer to Vehicle Theft Deterrent (VTD) Description .
Security Indicator
The red THEFT SYSTEM indicator on the instrument cluster is controlled by both the VTD system and the CTD system.
| • | The VTD system commands the body control module to control the indicator only when the ignition switch is ON. The indicator will illuminate for approximately three seconds when the ignition is in the ON position and no DTCs are set. The VTD system uses the indicator as a malfunction indicator. If a DTC is present, the indicator will illuminate and remain illuminated with the ignition in the ON position. |
| • | The CTD system commands the body control module to control the indicator only when the ignition switch is OFF. The CTD system uses the indicator to identify system status. |
