DRIVE UNIT (Continued)
REMOVAL
(1) Open the liftgate.
(2) Disconnect and isolate the negative battery
cable.
(3) Remove the link rod assembly from the liftgate
attachment point. Refer to Link Rod removal proce-
dure in this section.
(4) Remove the left rear D-pillar trim panel from
the vehicle. Refer to the Body section for the proce-
dure.
(5) Disconnect the wire harness connector from the
power liftgate drive unit assembly. Compress the
locking tab until the two connector halves can be
pulled straight apart.
CAUTION: Do not let the drive unit bolt retainers
drop into the body cavity. Rattles and customer
complaints could result.
(6) Remove the power drive unit retaining bolts.
(7) Unhook the drive unit assembly from the D-pil-
lar and remove the unit from the vehicle.
INSTALLATION
(1) Install the drive unit assembly on the D-pillar.
(2) Install the power drive unit retaining bolts.
Torque the bolts to 250 in. lbs. (28 N·m).
(3) Connect the wire harness connector on the
power liftgate drive unit assembly.
(4) Install the link rod assembly on the drive unit
attachment point. Refer to the Link Rod installation
procedure in this section.
(5) Install the left rear D-pillar trim panel on the
vehicle. Refer to the Body section for the procedure.
(6) Install the link rod assembly on the liftgate
attachment point. Refer to the Link Rod installation
procedure in this section.
(7) Connect the negative battery cable.
(8) Using an appropriate scan tool, check and
erase any power liftgate control module diagnostic
trouble codes related to the door motor assembly.
(9) Verify power liftgate system operation. Cycle
the power liftgate through one complete open and
close cycle, this will allow the power liftgate control
module to relearn its cycle with the new components.
EXTERIOR HANDLE SWITCH
DESCRIPTION
All Pacifica vehicles are equipped with a exterior
liftgate handle switch. The exterior handle contains
an electronic release switch. The liftgate handle
switch is primarily used for manual opening of the
liftgate. Activation of the handle switch during a
automatic power close cycle will cause the liftgate to
POWER LIFTGATE SYSTEM 8Ns - 9
reverse direction. Activation of the handle switch
during an power open cycle will cause the power lift-
gate to disengage, allowing full manual operation.
The exterior handle switch cannot be adjusted or
repaired and if damaged it must be replaced. Consult
your Mopar™ parts catalog for a specific part num-
ber.
OPERATION
When the exterior liftgate handle switch is
depressed a hard-wired signal is detected by the
Body Control Module (BCM). The Body Control Mod-
ule then sends a PCI data bus message to the power
liftgate control module. The BCM message includes
lock status, which the power liftgate module inter-
prets. If operating conditions are met, the power lift-
gate module then applies power to the latch mounted
actuator, which moves the liftgate from the primary
closed and latched position to the open and movable
position.
If the liftgate is not pulled open within a few sec-
onds, once the latch releases, the latch will automat-
ically cinch closed.
REMOVAL
(1) Open the liftgate.
(2) Disconnect and isolate the negative battery
cable.
(3) Open the liftgate and remove the liftgate trim
panel. Refer to the Body section for the procedure.
(4) Disconnect the handle switch electrical connec-
tor.
(5) Remove the liftgate handle assembly from the
vehicle. Refer to the Body section for the procedure.
(6) Depress the two exterior handle switch retain-
ing tabs and roll the switch out of the handle assem-
bly.
INSTALLATION
(1) Install the handle switch in the handle assem-
bly.
(2) Install the liftgate handle. Refer to the Body
section for the procedure.
(3) Connect the liftgate handle electrical connector.
(4) Install the liftgate trim panel. Refer to the
Body section for the procedure.
(5) Connect the negative battery cable.
(6) Using an appropriate scan tool, check and
erase any power liftgate module diagnostic trouble
codes.
(7) Verify power liftgate system and handle switch
operation. Cycle the power liftgate through one com-
plete open and close cycle, this will allow the power
liftgate module to relearn its cycle with the new com-
ponents.
