Intrusion Sensing

The anti-theft function is armed if the transmitter sends the LOCK message to the control module/receiver when the ignition is OFF. When the hood, door, or trunk/tailgate is opened, the hood open, door contact, or trunk/tailgate open switch sends a "ground" signal to the control module/receiver. Unless the control module/receiver is disarmed, the siren will be activated when the "ground" signal is received from the trunk/tailgate open, hood open, or door contact switches.

The following actions disarm the anti-theft system:

• An UNLOCK message is received from the transmitter.
• Key operation is detected by the tamper switches. (The tamper switches are operated by the lock cylinders in the front doors and trunk/tailgate.)

The alarm will also be activated if the control module/receiver detects voltage from the ignition before either of the following conditions occur:

• An UNLOCK message is received from the transmitter.
• Key operation is indicated by the tamper switches.
