Content Theft Deterrent (CTD) Description and Operation: Notes
When armed, the content theft deterrent (CTD) system is designed to deter vehicle content theft by pulsing the horns and exterior lamps for approximately 30 seconds when an unauthorized vehicle entry is detected. However, the CTD system does not affect engine starting.
An unauthorized entry can be any of the following with the CTD system armed:
- When any door is opened without first being unlocked using the vehicle key or using the UNLOCK command from a keyless entry transmitter
- Unauthorized entry into the underhood area, if equipped with remote vehicle start
- Unauthorized entry into the rear compartment
- After a battery reconnect, if the battery was disconnected with the CTD system armed
The components of the CTD system are:
- Body Control Module (BCM)
- Remote Control Door Lock Receiver (RCDLR)
- Security indicator
- Door ajar switches
- Rear compartment lid ajar switch
- Hood ajar switch (if equipped)
