Disarming the UTD System

The UTD system is normally disabled by unlocking the door by using the door lock cylinder or remote transmitter. This allows normal owner entry into the vehicle without setting off the alarm.

To disarm the UTD system perform the following steps:

1. Insert the key in the door lock cylinder and rotate it as if normally unlocking the door.
2. Insert the correct Pass-Key� into the ignition lock cylinder on the steering column and turn ON the ignition switch.
3. Press the UNLOCK button on the remote transmitter or walk into range with the passive switch ON.

It is important to note that, somewhat like not being able to arm the system using the manual lock switch, manually unlocking the doors will not disable the UTD alarm mode. Also, using the power door unlock switch will not disable UTD alarm mode. Disconnecting the battery or pulling fuses will not disable alarm mode, since the BCM stores the theft deterrent status in the EEPROM, and will go back into alarm mode when the battery is reconnected. Only the three actions described above will successfully disarm UTD alarm mode.
