STANDARD PROCEDURE
LIFTGATE ADJUSTMENT
In order for the power liftgate system to function
properly the liftgate must move freely and smoothly.
The power liftgate system can accommodate for some
minor changes in the effort required to move the lift-
gate. However, in extreme conditions the liftgate may
need to be mechanically adjusted for proper fit and
finish. (Refer to 23 - BODY/DECKLID/HATCH/LIFT-
GATE/TAILGATE/LIFTGATE - INSTALLATION) for
detailed instructions.
If a problem exists with the power liftgate and it is
suspected to be extreme effort, check the liftgate prop
rods and hinges for free movement.
NOTE: Routine application of Mopar MP-50
T
or
equivalent on the chrome prop rod shafts and lift-
gate latch and hinges will help keep the liftgate in
good working order.
POWER LIFTGATE LEARN CYCLE
Any time a power liftgate component is removed,
replaced or a liftgate adjustment is performed a learn
cycle must be performed. This learn cycle enables the
power liftgate control module to learn or relearn
information (travel limits, resistance to door travel,
etc.) which allows it to perform properly and safely.
Perform the following to complete a power liftgate
learn cycle:
(1) Obtain a DRBIII
t, or equivalent scan tool.
(2) Connect the scan tool to the vehicle and check
for any power liftgate system stored Diagnostic Trou-
ble Codes (DTCs), correct and erase any stored
DTCs.
(3) Using the scan tool, Go into Test Routine Menu
and select the power open command.
(4) Select the power close command.
(5) The liftgate learn cycle is complete.
If a DRBIII
t or equivalent scan tool is not avail-
able, the learn cycle can be performed by actuating
the liftgate using any of the normal command
switches. Be certain to cycle the liftgate through a
complete open and close cycle before returning the
vehicle to service.
NOTE: If the power liftgate will not complete a full
cycle a problem exists with the power liftgate sys-
tem. (Refer to 8 - ELECTRICAL/POWER DOORS -
DIAGNOSIS AND TESTING).
CHIME/THERMISTOR
DESCRIPTION
The chime/thermistor assembly is a small capacitor
shaped electrical component mounted to the rear
license plate lamp housing assembly (Fig. 2) , located
just above the license plate. The chime portion of the
assembly controls the audible chime sound heard at
the rear of the vehicle when the power liftgate is in
motion. The thermistor portion of the assembly is a
temperature sensor, used by the power liftgate con-
trol module. The chime/thermistor assembly is a ser-
viceable component.
OPERATION
The chime/thermistor assembly performs two dif-
ferent functions for the power liftgate system. First,
the chime portion provides an audible chime sound
which is controlled by the power liftgate control mod-
ule. The chime/thermistor assembly is hardwired to
the power liftgate control module. Second the ther-
mistor provides a outside temperature reading by
way of a resistance reading supplied to the power
liftgate control module. As temperature increases the
resistance
reading
increases,
as
temperature
decreases the resistance reading decreases.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
