General Information

When an unauthorized vehicle entry is detected (any door is opened), the CTD system (when armed) deters vehicle theft by performing the following actions:
^ Pulsating the horns
^ Pulsating the exterior lamps

The Remote Function Actuator (RFA) module controls all alarm functions. When the RFA module has detected an unauthorized entry, the module applies the following circuits:
^ CKT 624 (BLK/WHT) (headlights control)
^ CKT 28 (BLK) (horns control)

The circuits are applied once per second for approximately 3 minutes until a valid input in order to disarm is received. The RFA module has the following 5 basic modes in order to operate the CTD system:
^ Disarmed
^ Standby
^ Delayed
^ Armed
^ Alarm

The 5 basic modes are described below.
1. The disarmed mode. The RFA module (CTD system) is in the disarmed mode until the following conditions are detected:
^ The ignition switch is turned to the LOCK position.
^ Any door is open.
^ The doors are locked by either of the following components:
- The power door lock switch.
- The keyless entry transmitter (key fob).
^ The RFA module goes directly to the delayed mode, under the following conditions:
- All of the doors are closed.
- The key fob is used in order to lock the doors.
2. The standby mode. The RFA module detects the above conditions and enters the standby mode. The RFA module illuminates the SECURITY indicator by grounding CKT 264 (DK GRN).

3. The delayed mode. When the last door is closed, the RFA module flashes the SECURITY indicator by intermittently grounding CKT 264 (DK GRN).
4. The armed mode. After 30 seconds, the RFA module enters the armed mode. The RFA turns off the SECURITY indicator.

5. The alarm mode. Any unauthorized forced entry activates the alarm mode. The RFA module flashes the headlights by intermittently grounding CKT 624 (BLK/WHT). The RFA sounds the horns by intermittently grounding CKT 28 (BLK) once per second for approximately 3 minutes. After 3 minutes, the CTD system returns to the armed mode. If a valid input in order to disarm is received, the RFA module returns to the disarmed mode.
