tures, including:
²Automatic resetting circuit breakers
²Blade-type fuses
²Bus bars
²Cartridge fuses
²Circuit splice blocks
²Flashers
²Fusible links
²Relays
OPERATION
The power distribution system for this vehicle is
designed to provide safe, reliable, and centralized dis-
tribution points for the electrical current required to
operate all of the many standard and optional facto-
ry-installed electrical and electronic powertrain,
chassis, safety, security, comfort and convenience sys-
tems. At the same time, the power distribution sys-
tem was designed to provide ready access to these
electrical distribution points for the vehicle techni-
cian to use when conducting diagnosis and repair of
faulty circuits. The power distribution system can
also prove useful for the sourcing of additional elec-
trical circuits that may be required to provide theelectrical current needed to operate many accessories
that the vehicle owner may choose to have installed.

INTEGRATED POWER MODULE
DESCRIPTION
The Integrated Power Module (IPM) is a combina-
tion of the Power Distribution Center (PDC) and the
Front Control Module (FCM). The IPM is located in
the engine compartment, next to the battery. (Fig. 1).
The PDC mates directly with the FCM to form the
IPM. The PDC is a printed circuit board based mod-
ule that contains fuses and relays, while the FCM
contains the electronics controlling the IPM and
other functions. This IPM connects directly to the
battery positive through a four pin connector. The
ground connection is through two other connectors.
Terminal Pick Kit 6680
RS8W-97 POWER DISTRIBUTION SYSTEM8W-97-1

The IPM provides the primary means of voltage dis-
tribution and protection for the entire vehicle.
OPERATION
All of the current from the battery and the gener-
ator output enters the Integrated Power Module
(IPM) through a four- pin connector on the bottom of
the module. Internal connections of all of the power
distribution center circuits is accomplished by a com-
bination of bus bars and a printed circuit board.
REMOVAL
(1) Disconnect the negative and positive battery
cables.
(2) Remove the battery thermal guard.
(3) Remove the battery (Refer to 8 - ELECTRI-
CAL/BATTERY SYSTEM/BATTERY - REMOVAL).
(4) Using a flat-bladed screwdriver, twist the Inte-
grated Power Module (IPM) bracket retaining latch
outward to free the IPM from its mounting bracket
(Fig. 2).
(5) Rotate the IPM counter-clockwise to access and
disconnect the electrical connectors (Fig. 3).
(6) Remove the IPM bracket clips from the hinge.
INSTALLATION
(1) Snap the left side of the Integrated Power Mod-
ule (IPM) housing in its mounting bracket and con-
nect the various electrical connectors.NOTE: Ensure that the Connector Positive Assur-
ance (CPA) on the five-pin B+ connector is posi-
tively engaged to prevent generating a Diagnostic
Trouble Code (DTC).
(2) Rotate the IPM clock-wise until secured in
mounting bracket. An audible click may be heard.
(3) Install the battery (Refer to 8 - ELECTRICAL/
BATTERY SYSTEM/BATTERY - INSTALLATION).

IOD FUSE
DESCRIPTION
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed from its normal
cavity in the Integrated Power Module (IPM) when
the vehicle is shipped from the factory. Dealer per-
sonnel are to remove the IOD fuse from the storage
location and install it into the IPM fuse cavity
marked IOD as part of the preparation procedures
performed just prior to new vehicle delivery.
The IOD fuse is a 20 ampere blade-type mini fuse
and, when removed, it is stored in a fuse cavity adja-
cent to the washer fuse within the IPM.
OPERATION
The term ignition-off draw (IOD) identifies a nor-
mal condition where power is being drained from the
battery with the ignition switch in the Off position.
The IOD fuse feeds the memory and sleep mode func-
tions for some of the electronic modules in the vehicle
as well as various other accessories that require bat-
tery current when the ignition switch is in the Off
position, including the clock. The only reason the
IOD fuse is removed is to reduce the normal IOD of
the vehicle electrical system during new vehicle
transportation and pre-delivery storage to reduce
battery depletion, while still allowing vehicle opera-
tion so that the vehicle can be loaded, unloaded and
moved as needed by both vehicle transportation com-
pany and dealer personnel.
The IOD fuse is removed from the Integrated
Power Module (IPM) fuse cavity when the vehicle is
shipped from the assembly plant. Dealer personnel
must install the IOD fuse when the vehicle is being
prepared for delivery in order to restore full electrical
system operation. Once the vehicle is prepared for
delivery, the IOD function of this fuse becomes trans-
parent and the fuse that has been assigned the IOD
designation becomes only another Fused B(+) circuit
fuse. The IOD fuse serves no useful purpose to the
dealer technician in the service or diagnosis of any
vehicle system or condition, other than the same pur-
pose as that of any other standard circuit protection
device.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed approximately thirty days. However, it mustbe remembered that removing the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than thirty days,
the battery negative cable should be disconnected to
eliminate normal IOD; and, the battery should be
tested and recharged at regular intervals during the
vehicle storage period to prevent the battery from
becoming discharged or damaged.
POWER OUTLET
DESCRIPTION
Two power outlets are installed in the instrument
panel center lower bezel. Two additional power out-
lets are incorporated into the left rear C-pillar and
the center console (if equipped). The power outlets
bases are secured by a snap fit. A hinged plug flips
closed to conceal and protect the power outlet base
when not in use.
OPERATION
The power outlet base or receptacle shell is con-
nected to ground, and an insulated contact in the
bottom of the shell is connected to battery current.
The power outlet on the instrument panel marked
with a battery receives battery voltage from a fuse in
the Integrated Power Module (IPM) at all times. The
other power outlet on the instrument panel marked
with a key receives battery voltage only when the
key is in the on position.
The power outlet located in the center console
receives battery voltage all the time when positioned
between thefront seatsand key-on voltage when
positioned between therear seats. The power outlet
located on the C-pillar receives battery voltage only
when the key is in the ON position.

ENGINE 2.4L
DESCRIPTION
The 2.4 Liter (148 cu. in.) in-line four cylinder
engine is a double over head camshaft with hydraulic
lash adjusters and four valve per cylinder design.
The engine is free-wheeling; meaning it has provi-
sions for piston-to-valve clearance. However valve-to-
valve interference can occur, if camshafts are rotated
independently.
The cylinders are numbered from front of the
engine to the rear. The firing order is 1±3±4±2.
The engine identification number is located on the
rear of the cylinder block (Fig. 1).
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - ENGINE
DIAGNOSIS - INTRODUCTION
Engine diagnosis is helpful in determining the
causes of malfunctions not detected and remedied by
routine maintenance.
These malfunctions may be classified as either
mechanical (e.g., a strange noise), or performance
(e.g., engine idles rough and stalls).
Refer to the Engine Mechanical and the Engine
Performance diagnostic charts, for possible causes
and corrections of malfunctions (Refer to 9 - ENGINE
- DIAGNOSIS AND TESTING - MECHANICAL)
(Refer to 9 - ENGINE - DIAGNOSIS AND TESTING
- PERFORMANCE).
For fuel system diagnosis, (Refer to 14 - FUEL
SYSTEM/FUEL DELIVERY - DIAGNOSIS AND
TESTING).
Additional tests and diagnostic procedures may be
necessary for specific engine malfunctions that can-
not be isolated with the Service Diagnosis charts.
Information concerning additional tests and diagno-
sis is provided within the following:
²Cylinder Compression Pressure Test
²Cylinder Combustion Pressure Leakage Test
²Engine Cylinder Head Gasket Failure Diagnosis

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 outlet on
the cover.
²Remove the PCV valve hose from the cylinder
head cover. Cap or plug the PCV valve outlet 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.
