Rear Integration Module (RIM)

The CTD system is an internal function of the Rear Integration Module (RIM) which utilizes class 2 serial data and various switch input information to perform CTD functions. When the RIM detects an unauthorized entry, the RIM sends a message via the serial data circuit to the DIM to activate the horns and exterior lamps. The RIM has 5 basic modes. Disarmed standby, delayed, armed, and alarm for operating the CTD system. The 5 modes transition from one step to the next in the following order:

1. When in the disarmed mode, ignition is OFF and any door is open the RIM commands the instrument cluster to flash the SECURITY indicator via the class 2 serial data circuit. The RIM has the CTD system in a disarmed mode until the following conditions are detected:
- Ignition key turned to the OFF position
- Any door open
- Doors locked by either the power door lock switch or the LOCK button on the keyless entry transmitter
2. The RIM enters the standby mode when the above conditions are detected. In standby mode the RIM commands the instrument cluster to illuminate the SECURITY indicator via the class 2 serial data circuit. If all the doors are closed and the LOCK button on the keyless entry transmitter is used, the RIM enters the delayed mode.
3. When the last door is closed, the RIM enters the delayed mode for 30 seconds. In delayed mode the RIM commands the instrument cluster to illuminate the SECURITY indicator on steady via the class 2 serial data circuit.

IMPORTANT: The CTD system can be armed with the windows or sunroof open.

4. After 30 seconds, the RIM enters the armed mode. In armed mode the RIM commands the instrument cluster to turn off the SECURITY indicator via the class 2 serial data circuit. Any forced entry activates the alarm mode.
5. When the RIM detects a forced entry, the RIM enters the alarm mode. The RIM commands the DIM to activate the horn and exterior lamps for 30 seconds via a class 2 serial data circuit. This is followed by a 3 minute time-out of the horns, during the time-out period the horns are no longer active. If a new intrusion is detected during the time-out, the horn is not active. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode.
