Activating the UTD System

An illegal intrusion is defined as activity on any one of the following BCM inputs without the BCM first noting proper disarming of the UTD system:

- Driver door ajar switch
- Courtesy light switch
- Passenger door ajar switch
- Hatch ajar switch
- Turn ON the ignition switch (with an invalid PASS Key Detected)
- Hood ajar switch (export only)
- Park/headlamp switch
- Power door unlock switch

If the BCM senses an intrusion it enters alarm mode. The BCM sounds the vehicle horns and/or flashes the lights (depending on selected personalize options) at approximately once a second, disables engine cranking through the PASS-Key(R) system, and the PCM disables fuel delivery. The alarm mode is active for approximately 2 minutes (30 seconds export) with the ignition and fuel system disabled. This is followed by a 3 minute time-out with the horn no longer active. If no new intrusions are detected after the time-out, the horn is kept OFF. The system must be disarmed or the intrusion condition removed after the time-out for the system to exit alarm mode and the BCM to re-enable the ignition and PCM re-enable the fuel system.
