The red THEFT SYSTEM indicators on the instrument cluster is controlled by both the VTD system and the CTD system.

The indicators will illuminate for approximately three seconds when the ignition is in the ON position and no DTCs are set. The VTD system uses the indicators as a malfunction indicators. If a DTC is present, the indicators will illuminate and remain illuminated with the ignition in the ON position.
^ The CTD system commands the body control module to control the indicators only when the ignition switch is OFF. The CTD system uses the indicators to identify system status.
