The theft deterrent system on this vehicle is comprised
of two 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 IPC illuminates the SECURITY indicator in the message center as
determined by the Vehicle Theft Deterrent (VTD) system. The IPC receives a
class 2 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 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:
