Pacifica V6-3.8L VIN L (2005)
Door Ajar System
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.
Door Modules
A multiplexed Driver Door Module (DDM) is located in the driver door. The DDM controls the following features:
-
power door locks
-
automatic (rolling) door locks
-
driver front window and driver rear window, including express down for both
-
a window lockout feature for all passenger power windows
-
memory recall functions (radio, adjustable pedals, memory seats and driver mirror)
-
driver memory mirror
-
driver power mirror
-
driver heated mirror
-
door key cylinder disarm (driver door only)
-
door lock inhibit
-
switch learning features
-
central lock from the key cylinder (driver door only)
-
central unlock from the key cylinder and auto unlock on exit (driver door only)
A multiplexed Passenger Door Module (PDM) is located in the front passenger door. The PDM controls the following features:
-
power door locks
-
passenger front window and passenger rear window, including express down for both
-
passenger memory mirror
-
passenger power mirror
-
passenger heated mirror
Reduced wiring complexity is a key advantage of using multiplexed door modules. These modules are addressable with the DRBIII(R) from the "Body"
menu to facilitate faster and easier diagnosis. In addition, the door nodes offer:
-
battery protection
-
door lock inhibit this feature disables the door lock functions if the key is in the ignition and either front door is ajar. Pressing the RKE lock/
unlock button under these conditions will result in normal lock/unlock activation.
POWER WINDOWS
The driver can control all of the power windows from the Driver Door Module (DDM) while each passenger can control their own power window from
the power window switch in their respective door. The DDM also has a lockout switch that prevents power window operation from the power window
switch in each passenger door. When in lockout mode, the lockout switch illuminates in red and each passenger window switch LED turns off indicating
the respective switch is inactive. Another feature allows power window operation to continue from any power window switch for 45 seconds after
turning off the ignition, but only if the front doors remain closed. Still another power window feature is the Express Down feature. This feature works on
all four windows and is activated by pressing the power window switch into the second detent. Once activated, the operator can release the power
window switch and the power window will travel to the full open position. To stop the Express Down feature, momentarily pull the switch in the up
direction.
When a rear seat passenger actuates a rear power window switch, the respective door module, DDM or PDM, receives a multiplex signal. In turn, the
door module supplies 12 volts and ground, in the appropriate direction, to the up and down window motor circuits of the respective rear door power
window.
POWER DOOR LOCKS
The power door locks operate:
-
From the front door lock switches.
-
From remote keyless entry.
-
From the auto (rolling) door lock feature. This feature will lock all of the door locks, if all of the doors are closed and the vehicle speed goes
above 15 mph (24 km/h).
-
From the auto unlock on exit feature.
This feature will unlock all of the door locks when the vehicle is stopped, the transmission is in neutral or park and the driver door is opened.
-
From the central unlock from the key cylinder feature.
-
This feature will unlock all of the door locks if the operator turns the key cylinder toward the front of the vehicle twice within 5 seconds. The
first time the operator turns the key cylinder toward the front of the vehicle the feature will unlock only the driver door lock. If within 5
seconds the operator releases the key cylinder and again turns it toward the front of the vehicle all of the passenger door locks will unlock.
