Security Indicator Operation

SECURITY
The IPC illuminates the SECURITY indicator in the message center as determined by the Vehicle Theft Deterrent (VTD) system. The IPC receives a message from the theft deterrent controller module requesting illumination.
^ The VTD system requests the IPC to illuminate the indicator only when the ignition switch is ON. The VTD system uses the indicator as a malfunction indicator.
^ The Content Theft Deterrent (CTD) system requests the IPC to illuminate the indicator only when the ignition switch is OFF. The CTD system uses the indicator to identify system status.
