Pacifica V6-3.8L VIN L (2005)
Door/Trunk Ajar Indicator/Lamp: Description and Operation
The driver door-ajar switch provides a switch state input to the Driver Door Module (DDM). The front passenger door ajar switch provides a switch
state input to the Passenger Door Module (PDM). The left rear passenger door ajar switch, the right rear passenger door ajar switch, and the liftgate ajar
switch provide switch state inputs to the Body Control Module (BCM). The BCM and the door modules use these inputs to determine the position of
each door and the liftgate. The DRBIII(R) will display the switch-state of each ajar switch in Inputs/Outputs. It is important to note that the DRBIII(R)
will display OPEN next to the switch state of a door or liftgate that is closed, and CLOSED next to the switch state of a door or liftgate that is open. If
the DRBIII(R) displays CLOSED when the respective door or liftgate is closed, this indicates a shorted ajar circuit. If the DRBIII(R) displays OPEN
when the respective door or liftgate is open, this indicates an open ajar circuit.
