Intrusion Sensing

The antitheft function is armed if the transmitter sends the LOCK message to the module/receiver when the ignition is OFF If the hood, the door, or the rear deck lid is opened, the hood open, the door contact, or the rear deck lid open switch will change its input to the module/receiver, and the alarm will be activated unless either of the following conditions has occurred:
- An UNLOCK message was received from the transmitter.
- The front door tamper or the rear deck lid tamper switches indicate key operation.

The alarm will also be activated if the ignition input is changed to battery voltage before either of the following conditions occurs:
- An UNLOCK message was received from the transmitter.
- The front door tamper or the rear deck lid tamper switches indicate key operation.
- The alarm will also be activated if the antitheft function has been armed and the ultrasonic sensor (optional) detects movement within the vehicle before the front door or rear deck lid tamper switches have indicated key operation.
