Security Indicator: Notes

The security indicator on the instrument cluster is controlled by both the VTD System and the CTD System. The security indicator is controlled by the body control module (BCM) via a discrete output.

• The VTD system commands the BCM to control the security indicator only when the ignition switch is ON. The VTD system uses the security indicator as a malfunction indicator.
• The CTD system, integral to the BCM, controls the security indicator only when the ignition switch is OFF. The CTD system uses the indicator to identify system status.
