Door Switch: Description and Operation
DOOR AJAR SWITCHES
The CTD system uses the door ajar switches in the door latch assemblies as one method to activate the alarm. The body control module (BCM) monitors
all door ajar switches via a discrete input from each door ajar switch. If the BCM receives a ground signal from a door ajar switch when the CTD system
is armed, the BCM activates the alarm.
