Circuit Description
WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The security indicator is used by both the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD) system. The security indicator is controlled by the body control module (BCM) via the security indicator control circuit. When VTD or CTD requests the security indicator be illuminated, the BCM grounds the security indicator control circuit, illuminating the security indicator.
