The theft deterrent system on this vehicle is comprised of 2 separate
systems, the vehicle theft deterrent (VTD) system and the content theft deterrent
(CTD) system. The VTD system prevents drive away theft by keeping the vehicle from
starting. The CTD system is the vehicle alarm system which discourages unauthorized
entry into the vehicle. These systems are described and diagnosed separately within
this section.
Theft System Indicators
Security Indicator
The instrument panel cluster (IPC) illuminates the security indicator as determined
by the vehicle theft deterrent (VTD) system and the content theft deterrent (CTD)
system. The IPC receives a message from the theft deterrent module (TDM) or the body
control module (BCM) via the serial data circuit 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.
For specific VTD condition that will illuminate the security indicator, refer to
Vehicle Theft Deterrent (VTD) Description and Operation
. |
| • | The CTD system requests the IPC to illuminate the indicator only when
the ignition switch is OFF. The CTD system uses the indicator in order to identify
system status. For specific CTD condition that will illuminate the security indicator,
refer to
Content Theft Deterrent (CTD) Description and Operation
. |
| • | The IPC performs the displays test at the start of each ignition cycle.
The indicator illuminates for approximately 3 seconds. |
Keyless Entry System (w/AU0)
The keyless entry system functions interact with the content theft deterrent
(CTD) system but is diagnosed as a stand-alone system. Refer to
Keyless Entry System Description and Operation
.
Radio with Theftlock
The theft deterrent system does not interact with radio theft lock equipped
vehicles. Radio theft lock is diagnosed as a stand-alone system. Refer to
