Intrusion Sensing

The anti-theft function is armed if the transmitter sends the LOCK message to the ISU. When the ignition is OFF. If the hood, the door, or the rear deck lid is opened, the hood open, the door contract, or the rear deck lid open switch will change its input to the ISU, 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 anti-theft 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.
