System Triggering

The alarm can be triggered by the following events if the system has been armed and has not been disarmed first.

1. Open any door.
2. Open the hood (if the hood was open when the system was armed, it must be closed before it can trigger the alarm).
3. Disturb the ignition keylock cylinder sensor affecting the monitored resistance to ground. A disturbance of this sensor is the only event which will trigger an unarmed alarm.
4. The anti-theft system may be triggered inadvertently when the module is disconnected and then reconnected. To avoid this condition, disconnect the smaller 22-pin connector first. This alarm trigger is stored by the receiver assembly as Ignition Tamper Sensor Trigger event (IGNTAM) in the diagnostic list of alarm trigger events.

NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT LED. PANIC is stored in the diagnostic list of alarm events to aid in diagnosis.

When the system is triggered, the starter interrupt and perimeter alarm will operate as follows:

STARTER INTERRUPT - starter circuit interrupted until system is disarmed. The normally closed external starter interrupt relay will be pulled in to disallow power to travel through the starter circuit.

PERIMETER ALARM - approx. 250 ms on, 450 ms off cycle for two minutes and 45 seconds for North America.

- Parking lamps
- Horn
- THEFT LED

The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is seen as normal and then in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).
