Lincoln Aviator: Passive Anti-Theft System (PATS) / Description and Operation - Passive Anti-Theft System (PATS) - Overview

Overview

The PATS deters the vehicle from theft by preventing the vehicle from starting unless a valid programmed key is detected inside the vehicle when the START/STOP button is pressed.

The PATS does not disable an already running vehicle.

Backup Starting

NOTE: There are certain areas within the vehicle where the passive key may not be detected and the message center displays No Key Detected. If the passive key is in the far outside edges of the interior (such as in a door map pocket or above a sun visor), it may not be detected. Move the passive key to a different location and try to turn the ignition on.

When the BCM does not detect a valid programmed passive key in the passenger compartment, the No Key Detected message displays in the message center when the START/STOP button is pressed.

In the event this message displays, place a programmed passive key in the backup location to allow the vehicle to start. When the START/STOP button is pressed, the center PATS antenna activates the passive key and the identification code is sent to the BCM. The passive key must be oriented correctly in the backup starting location. For more information and to identify the backup starting location, refer to “Failure to Start” and “backup slot” in the Owner's Literature.

No Key Detected Message

NOTE: Some brands/types of mobile phone or laptop computer chargers may cause interference that could lead to a PATS concern if the passive key is within close proximity of the charger. If a concern is observed, move the passive key away from the charger and attempt to turn the ignition on.

The No Key Detected message displays in the IPC message center when:

  • When the ignition is OFF, the START/STOP button is pressed and a programmed passive key is not detected inside the vehicle. If a component failure (such as a depleted passive key battery or BCM failure) is causing the No Key Detected message to display, the backup starting method can be used.
  • When the ignition is ON, the driver exits the vehicle with the programmed passive key and closes the door.
  • The BCM activates the PATS center antenna and keyless entry rear antenna to search the inside of the vehicle for a passive key any time a door or the liftgate is opened and then closed with the vehicle running and the first times each drive cycle the vehicle speed exceeds 15 km/h (9 mph). The No Key Detected message displays in the message center and the horn chirps twice when the ignition is on and a passive key is no longer detected inside the vehicle.

This strategy deters the passive key from being separated from a vehicle with the ignition ON. If a passive key is no longer detected in the vehicle, the vehicle continues to run. If the START/STOP button is pressed to turn the vehicle off, the engine can be restarted without a passive key present inside the vehicle for approximately 20 seconds. After 20 seconds have elapsed, a passive key must be present to transition the ignition to ON.

Automatic Engine Idle Shutdown

The automatic engine idle shutdown feature monitors the state of the vehicle to determine when the engine is powered with no user interaction for approximately 30 minutes. Approximately 30 seconds prior to the shutdown, a message displays in the message center to inform the operator a vehicle shutdown is imminent. This includes shutting down the engine and turning the ignition off. When the shutdown occurs, press the brake and START/STOP button to re-start the vehicle (a valid programmed passive key is required).

The conditions required to begin the automatic engine idle shutdown feature are:

  • power pack enabled
    • engine running
  • brake pedal not pressed
  • accelerator pedal not pressed
  • remote start not active
  • transmission in P (park) or N (neutral)
  • diagnostic scan tool not connected to the vehicle

Once these conditions are met, a time-out starts. When the time-out period ends and none of the listed conditions changed, the automatic engine idle shutdown event occurs.
