Theft System

The IPC illuminates the theft system indicator as determined by the Vehicle Theft Deterrent (VTD) system. The Body Control Module (BCM) sends a class 2 message to the IPC 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 IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
