Perimeter Alarm
The BCM controls the operation of the perimeter alarm. It monitors inputs from the RKE system (includes the keyless entry keypad), the power door lock system and the IA system to determine when to arm the perimeter alarm.
The BCM monitors all of the door ajar switches, the luggage compartment lid ajar switch and the hood ajar switch to determine when to activate the perimeter alarm. When the BCM detects an input indicating an unauthorized entry into the vehicle, the BCM activates the perimeter alarm by sounding the horn and flashing all the turn signals and interior courtesy lamps at regular intervals.
The BCM monitors the RKE system (includes the keyless entry keypad), the IA system and PATS to determine when to disarm the perimeter alarm.
