Door Switch: Description and Operation
DOOR AJAR SWITCH
The door ajar switches are integral to the door latches on each front door. The door ajar switches for the side and rear doors are mounted to the
door opening pillars. Each of these switches close a path to ground for the Central Timer Module (CTM) when a door is opened, and open the
ground path when a door is closed.
The door ajar switches cannot be repaired and, if faulty or damaged, the door latch unit (front doors) or door ajar switch unit (side or rear doors)
must be replaced.
