WARNING: BE CERTAIN TO READ ALL WARNINGS
AND CAUTIONS (NOTED BELOW) IN POWER LIFT-
GATE SYSTEM OPERATION BEFORE ATTEMPTING
ANY SERVICE OF THE POWER LIFTGATE SYSTEM
OR COMPONENTS.
OPERATION
With the push of a power liftgate open/close com-
mand switch (key fob or overhead console mounted) a
signal is sent out on the J1850 PCI Data Bus circuit.
This signal is detected at the body control module
(BCM). The BCM then sends a signal out on the
J1850 PCI Data Bus circuit to the power liftgate
module. The power liftgate module then signals the
power liftgate motor to start an open or close cycle,
depending on what position the liftgate is in open or
closed.
During a liftgate open or close cycle, if the power
liftgate module detects sufficient resistance to liftgate
travel, such as an obstruction in the liftgates path,
the power liftgate control module will immediately
stop the liftgate movement and reverse travel to the
full open or closed position. The ability for the power
liftgate module to detect resistance to liftgate travel
is accomplished by hall effect sensors, drive motor
speed and pinch sensors (tape switches).
The power liftgate control module has the ability to
learn. Anytime the liftgate is opened or closed using
the power liftgate system the module learns from its
cycle. If a replacement power liftgate component is
installed or a liftgate adjustment is made, the mod-
ule will relearn the effort and/or time required to
open or close the door. This learn cycle can be per-
formed with a Diagnostic Scan Tool, such as the
DRB IIItor with a complete cycle of the liftgate,
using any one of the command switches. Refer to
Standard Procedures in this section for detailed
instructions.
The power liftgate system is designed with a num-
ber of system inhibitors. These inhibitors are neces-
sary for safety and / or feasibility of the power
liftgate system. Refer to power liftgate system inhib-
itors noted below:
POWER LIFTGATE SYSTEM INHIBITORS

WARNING: BE CERTAIN TO READ ALL WARNINGS
AND CAUTIONS IN POWER SLIDING DOOR OPER-
ATION BEFORE ATTEMPTING ANY SERVICE OF
POWER SLIDING DOOR SYSTEM OR COMPO-
NENTS.
OPERATION
With the push of a power sliding door open/close
command switch (key fob, overhead console or B-pil-
lar mounted) a signal is sent out to the Body Control
Module (BCM). The BCM then sends a signal out on
the PCI Data Bus circuit (J1850) to the power sliding
door module. The power sliding door module then
signals the power sliding door latch to release the
door to the unlatched and movable position. The
motor then starts an open cycle.
During the door open cycle, if the power sliding
door module detects sufficient resistance to doortravel, such as an obstruction in the door's path, the
power sliding door module will immediately stop door
movement and reverse door travel to the full open or
closed position. The ability for the power sliding door
module to detect resistance to door travel is accom-
plished by hall effect sensors and the door motor
speed.
The power sliding door control module has the abil-
ity to learn. Anytime a door is opened or closed using
the power sliding door system the module learns
from its cycle. If a replacement power sliding door
component is installed or a door adjustment is made,
the module must re-learn the effort required to open
or close the door. A learn cycle can be performed with
a Diagnostic Scan Tool, such as the DRB IIIt, or with
a complete cycle of the door, using any one of the
command switches. Refer to Standard Procedures in
this section for detailed instructions.
The power sliding door system is designed with a
number of system inhibitors. These inhibitors are
necessary for safety and/or feasibility of the power
sliding door system. See the power sliding door sys-
tem inhibitors noted below:
POWER SLIDING DOOR SYSTEM INHIBITORS
²The power sliding door must be in thefullopen
or closed position in order for the power sliding door
system to start a cycle. If the door is not in this posi-
tion (based on the input from the full open, pawl or
ratchet switches) the door control module will not
respond to command switch inputs.
²The vehicles transmission must be inpark or
neutralin order for the power sliding door system to
start a cycle.
²The vehicles child lockout switch must be in the
ªUNLOCKEDº position in order for the power sliding
door systems B-pillar switches to function.
²If multiple obstacles are detected during the
same power open or close cycle the power sliding
door may go into full manual mode.
²If severe Diagnostic Trouble Codes (DTC) are
stored in the power sliding door control module the
power sliding door may go into full manual mode.
²Due to the high pressure created in the passen-
ger compartment with the blower motor on high, the
power sliding door may not complete a power close
cycle unless a window is cracked, allowing the pres-
sure to escape. This situation will only be experi-
enced on some vehicles, or vehicles with brand new
side door weather seals installed. Refer to the Side
Door Adjustment procedure in the Standard Proce-
dures section of this group.
²The vehicles fuel tank filler door must be in the
closed position. Due to the sliding door interference
with the open fuel tank filler door, mechanical link-
age prevents the side door from opening and striking

able, Sentry Key programming will require the use of
a DRB IIItscan tool.
The steps required to program Sentry Keys with
two valid Sentry Keys follows:
(1) Obtain the blank Sentry Key(s) that need to be
programmed. Cut the keys to match the ignition lock
cylinder mechanical key codes.
(2) Insert one of the two valid Sentry Keys into the
ignition switch and turn the ignition switch to the
ON position.
(3) After the ignition switch has been in the ON
position for longer than three seconds, but no more
than fifteen seconds, cycle the ignition switch back to
the OFF position. Replace the first valid Sentry Key
in the ignition lock cylinder with the second valid
Sentry Key and turn the ignition switch back to the
ON position. The second valid Sentry Key must be
inserted within 15 seconds of removing the first valid
Sentry key.
(4) About ten seconds after the completion of Step
3, the indicator light will start to flash and a single
audible chime tone will sound to indicate that the
system has entered the9Customer Learn9program-
ming mode.
(5) Within sixty seconds of entering the9Customer
Learn9programming mode, turn the ignition switch
to the OFF position, replace the valid Sentry Key
with a blank Sentry Key transponder, and turn the
ignition switch back to the ON position.
(6) About ten seconds after the completion of Step
5, a single audible chime tone will sound and the
indicator light will stop flashing and stay on solid for
three seconds and then turn off to indicate that the
blank Sentry Key has been successfully programmed.
The SKIS will immediately exit the9Customer
Learn9programming mode and the vehicle may be
started using the newly programmed Sentry Key.
These steps must be completed in their entirety for
each additional Sentry Key to be programmed. If any
of the above steps are not completed in the given
sequence, or within the allotted time, the SKIS will
exit the9Customer Learn9programming mode and
the programming will be unsuccessful. The SKIS will
also automatically exit the9Customer Learn9pro-
gramming mode if:
²It sees a non-blank Sentry Key when it should
see a blank.
²If it has already programmed eight (8) valid
Sentry Keys.
²If the ignition switch is turned to the OFF posi-
tion for more than about fifty (50) seconds.
NOTE: If you attempt to start the vehicle while in
ªCustomer Learnº mode (LED flashing), the vehiclewill behave as though an invalid key is being used
(i.e. the engine will stall after two (2) seconds of
running). No faults will be logged.
NOTE: Once a Sentry Key has been programmed to
a particular vehicle, it cannot be used on any other
vehicle.
VTSS/SKIS INDICATOR LAMP
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses
an indicator light to convey information on the status
of the system to the customer. This light is shared
with the Vehicle Theft Security System (VTSS). The
light is located in the Mechanical Instrument Cluster
(MIC). The indicator light is controlled by the Body
Control Module (BCM), via Programmable Communi-
cation Interface (PCI) data bus communication with
the MIC, based upon messages it receives from the
Sentry Key Immobilizer Module (SKIM) on the PCI
data bus.
OPERATION
The Mechanical Instrument Cluster (MIC) per-
forms a four second bulb check via PCI communica-
tion with the Sentry Key Immobilizer Module
(SKIM). After the bulb check, the lamp is controlled
according to SKIM messages. Then, the SKIM sends
messages to the BCM to operate the light based upon
the results of the SKIS self tests. The light may be
actuated in two possible ways, flashing or on solid. If
the light comes on and stays on solid after a pow-
er-up test, this indicates that the SKIM has detected
a system malfunction. If the SKIM detects an invalid
key when the ignition switch is moved to the ON
position, it sends a message on the PCI bus to the
BCM, to flash the light. The SKIM can also send a
message to flash the light and generate a single audi-
ble chime at the same time. These two events occur-
ring simultaneously indicate that the SKIS has been
placed into the9Customer Learn9mode. Refer to
Electrical, Vehicle Theft Security, Transponder Key,
Standard Procedure - Transponder Programming for
more information on the9Customer Learn9mode. If
the light comes on and stays on after the power-up
test, diagnosis of the SKIS should be performed
using a DRB IIItscan tool and the appropriate Body
Diagnostic Procedures manual. The light is not a ser-
viceable component.

3. Carbon in oil ring slots. 3. Install new rings.
4. Rings fitted too tightly in grooves. 4. Remove rings and check
grooves. If groove is not proper
width, replace piston.
5. Worn valve guide(s). 5. Replace cylinder head assembly.
6. Valve stem seal(s) worn or
damaged.6. Replace seal(s).
DIAGNOSIS AND TESTING - ENGINE OIL LEAK
INSPECTION
Begin with a thorough visual inspection of the
engine, particularly at the area of the suspected leak.
If an oil leak source is not readily identifiable, the
following steps should be followed:
(1) Do not clean or degrease the engine at this
time because some solvents may cause rubber to
swell, temporarily stopping the leak.
(2) Add an oil soluble dye (use as recommended by
manufacturer). Start the engine and let idle for
approximately 15 minutes. Check the oil dipstick to
make sure the dye is thoroughly mixed as indicated
with a bright yellow color under a black light.
(3) Using a black light, inspect the entire engine
for fluorescent dye, particularly at the suspected area
of oil leak. If the oil leak is found and identified,
repair as necessary.
(4) If dye is not observed, drive the vehicle at var-
ious speeds for approximately 24 km (15 miles), and
repeat inspection.
(5)If the oil leak source is not positively
identified at this time, proceed with the air leak
detection test method as follows:
²Disconnect the fresh air hose (make-up air) at
the cylinder head cover and plug or cap the nipple on
the cover.
²Remove the PCV valve hose from the cylinder
head cover. Cap or plug the PCV valve nipple on the
cover.
²Attach an air hose with pressure gauge and reg-
ulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to
more than 20.6 kpa (3 PSI) of test pressure.²Gradually apply air pressure from 1 psi to 2.5
psi maximum while applying soapy water at the sus-
pected source. Adjust the regulator to the suitable
test pressure that provides the best bubbles which
will pinpoint the leak source. If the oil leak is
detected and identified, repair per service manual
procedures.
²If the leakage occurs at the crankshaft rear oil
seal area, refer to the section, Inspection for Rear
Seal Area Leak.
(6) If no leaks are detected, turn off the air supply.
Remove the air hose, all plugs, and caps. Install the
PCV valve and fresh air hose (make-up air). Proceed
to next step.
(7) Clean the oil off the suspect oil leak area using
a suitable solvent. Drive the vehicle at various
speeds approximately 24 km (15 miles). Inspect the
engine for signs of an oil leak by using a black light.
NOTE: If oil leakage is observed at the dipstick tube
to block location; remove the tube, clean and reseal
using MoparTStud & Bearing Mount (press fit tube
applications only), and for O-ring style tubes,
remove tube and replace the O-ring seal.
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the
source of an oil leak in the rear seal area of the
engine, a more involved inspection is necessary. The
following steps should be followed to help pinpoint
the source of the leak.
If the leakage occurs at the crankshaft rear oil seal
area:
(1) Disconnect the battery.
(2) Raise the vehicle.
