The theft deterrent system on this vehicle is comprised
of2o separate systems, the vehicle theft deterrent (VTD) system and the
optional content theft deterrent (CTD) system. VTD prevents drive away
theft by keeping the vehicle from starting. CTD is the vehicle alarm
system which discourages unauthorized entry into the vehicle. These
systems are described and diagnosed separately within this section.
Theft System Indicator(s)
SECURITY
The Instrument Panel Cluster (IPC) illuminates the SECURITY indicator
in the instrument cluster as determined by the Vehicle Theft Deterrent (VTD)
system. The BCM grounds the SECURITY indicator control circuit in order
to illuminate the indicator.
| • | The VTD system requests the IPC to illuminate the SECURITY indicator
only when the ignition switch is ON. The VTD system uses the indicator as
a malfunction indicator. |
| • | The Content Theft Deterrent (CTD) system uses the theft LED and
does not use the SECURITY indicator. |
Theft LED
The Body Control Module (BCM) illuminates the theft LED (on top of the
dash) based on the current Content Theft Deterrent (CTD) system operation
mode. The theft LED operates in the following modes:
