Perimeter Alarm Activation
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The perimeter alarm has a 12 second delay when the driver front door is opened without using a RKE transmitter, the keyless entry keypad, or a passive key to unlock the vehicle. During the delay, a chime sounds. If the perimeter alarm is not disarmed within the 12 second delay, the alarm activates.
The perimeter alarm activates when any of the following actions are performed:
- The driver front door is opened without first receiving an unlock command from the passive entry feature equipped), the keyless entry keypad, or a programmed RKE transmitter, and the 12 second delay has expired.
- Any other door, liftgate, or the hood is opened without first receiving an electronic unlock command from the passive entry feature, the keyless entry keypad, or a programmed RKE transmitter.
- The ignition transitions to RUN without a valid PATS key read received.
- The BCM detects an attempt by a diagnostic scan tool to establish communication on the CAN.
The perimeter alarm only activates 10 times per arming cycle. After that, the alarm does not activate. To enable the perimeter alarm again, disarm and arm it again.
