CLEANING
The following information details the recommended
cleaning procedures for the battery and related com-
ponents. In addition to the maintenance schedules
found in this service manual and the owner's man-
ual, it is recommended that these procedures be per-
formed any time the battery or related components
must be removed for vehicle service.
(1) Clean the battery cable terminal clamps of all
corrosion. Remove any corrosion using a wire brush
or a post and terminal cleaning tool, and a sodium
bicarbonate (baking soda) and warm water cleaning
solution (Fig. 1).
(2) Clean the battery tray and battery hold down
hardware of all corrosion. Remove any corrosion
using a wire brush and a sodium bicarbonate (baking
soda) and warm water cleaning solution. Paint any
exposed bare metal.
(3) If the removed battery is to be reinstalled,
clean the outside of the battery case and the top
cover with a sodium bicarbonate (baking soda) and
warm water cleaning solution using a stiff bristle

BATTERY CABLES
DESCRIPTION
The battery cables are large gauge, stranded cop-
per wires sheathed within a heavy plastic or syn-
thetic rubber insulating jacket. The wire used in the
battery cables combines excellent flexibility and reli-
ability with high electrical current carrying capacity.
The battery cables cannot be repaired and, if dam-
aged or faulty they must be replaced. Both the bat-
tery positive and negative cables are available for
service replacement only as a unit with the battery
positive cable wire harness or the battery negative
cable wire harness, which may include portions of
the wiring circuits for the generator and other com-
ponents on some models.
The battery cables feature a stamped brass clamp-
ing type female battery terminal crimped onto one
end of the battery cable wire and then solder-dipped.
A square headed pinch-bolt and hex nut are installed
at the open end of the female battery terminal clamp.
The battery positive cable also includes a red molded
rubber protective cover for the female battery termi-
nal clamp. Large eyelet type terminals are crimped
onto the opposite end of the battery cable wire and
then solder-dipped. The battery positive cable wires
have a red insulating jacket to provide visual identi-
fication and feature a larger female battery terminal
clamp to allow connection to the larger battery posi-
tive terminal post. The battery negative cable wires
have a black insulating jacket and a smaller female
battery terminal clamp.
OPERATION
The battery cables connect the battery terminal
posts to the vehicle electrical system. These cables
also provide a return path for electrical current gen-
erated by the charging system for restoring the volt-
age potential of the battery. The female battery
terminal clamps on the ends of the battery cable
wires provide a strong and reliable connection of the
battery cable to the battery terminal posts. The ter-
minal pinch bolts allow the female terminal clamps
to be tightened around the male terminal posts on
the top of the battery. The eyelet terminals secured
to the ends of the battery cable wires opposite the
female battery terminal clamps provide secure and
reliable connection of the battery to the vehicle elec-
trical system.
DIAGNOSIS AND TESTING - BATTERY CABLES
A voltage drop test will determine if there is exces-
sive resistance in the battery cable terminal connec-
tions or the battery cables. If excessive resistance is
found in the battery cable connections, the connec-
tion point should be disassembled, cleaned of all cor-
rosion or foreign material, then reassembled.
Following reassembly, check the voltage drop for the
battery cable connection and the battery cable again
to confirm repair.
When performing the voltage drop test, it is impor-
tant to remember that the voltage drop is giving an
indication of the resistance between the two points at
which the voltmeter probes are attached.EXAM-
PLE:When testing the resistance of the battery pos-
itive cable, touch the voltmeter leads to the battery
positive cable terminal clamp and to the battery pos-
itive cable eyelet terminal at the starter solenoid
B(+) terminal stud. If you probe the battery positive
terminal post and the battery positive cable eyelet
terminal at the starter solenoid B(+) terminal stud,
you are reading the combined voltage drop in the
battery positive cable terminal clamp-to-terminal
post connection and the battery positive cable.
VOLTAGE DROP TEST
WARNING: IF THE BATTERY SHOWS SIGNS OF
FREEZING, LEAKING, LOOSE POSTS, OR LOW
ELECTROLYTE LEVEL, DO NOT TEST, ASSIST-
BOOST, OR CHARGE. THE BATTERY MAY ARC
INTERNALLY AND EXPLODE. PERSONAL INJURY
AND/OR VEHICLE DAMAGE MAY RESULT.
WARNING: EXPLOSIVE HYDROGEN GAS FORMS IN
AND AROUND THE BATTERY. DO NOT SMOKE,
USE FLAME, OR CREATE SPARKS NEAR THE BAT-
TERY. PERSONAL INJURY AND/OR VEHICLE DAM-
AGE MAY RESULT.
WARNING: THE BATTERY CONTAINS SULFURIC
ACID, WHICH IS POISONOUS AND CAUSTIC. AVOID
CONTACT WITH THE SKIN, EYES, OR CLOTHING.
IN THE EVENT OF CONTACT, FLUSH WITH WATER
AND CALL A PHYSICIAN IMMEDIATELY. KEEP OUT
OF THE REACH OF CHILDREN.
WARNING: IF THE BATTERY IS EQUIPPED WITH
REMOVABLE CELL CAPS, BE CERTAIN THAT EACH
OF THE CELL CAPS IS IN PLACE AND TIGHT
BEFORE THE BATTERY IS RETURNED TO SER-
VICE. PERSONAL INJURY AND/OR VEHICLE DAM-
AGE MAY RESULT FROM LOOSE OR MISSING
CELL CAPS.

SPECIAL TOOLS
GENERATOR
DESCRIPTION
The generator is belt-driven by the engine using a
serpentine-type drive belt. It is serviced only as a
complete assembly. If the generator fails for any rea-
son, the entire assembly must be replaced.
On certain engines, the decoupler pulley may be
replaced separately.
OPERATION
As the energized rotor begins to rotate within the
generator, the spinning magnetic field induces a cur-
rent into the windings of the stator coil. Once the
generator begins producing sufficient current, it also
provides the current needed to energize the rotor.
The stator winding connections deliver the induced
AC current to 3 positive and 3 negative diodes for
rectification. From the diodes, rectified DC current isdelivered to the vehicle electrical system through the
generator battery terminal.
Although the generators appear the same exter-
nally, different generators with different output rat-
ings are used on this vehicle. Be certain that the
replacement generator has the same output rating
and part number as the original unit. Refer to Spec-
ifications and see Generator Ratings for amperage
ratings and part numbers.
Noise emitting from the generator may be caused
by: worn, loose or defective bearings; a loose or defec-
tive drive pulley (decoupler pulley); incorrect, worn,
damaged or misadjusted fan drive belt; loose mount-
ing bolts; a misaligned drive pulley or a defective sta-
tor or diode.
An instrument panel mounted, battery charge indi-
cator lamp is used. When the key is in the on posi-
tion, the lamp will be illuminated. This is done as a
bulb check. If this lamp remains illuminated while
the engine is running, a Diagnostic Trouble Code
(DTC) has been detected for the charging system.
REMOVAL
CAUTION: DISCONNECT NEGATIVE CABLE FROM
BATTERY BEFORE REMOVING BATTERY OUTPUT
WIRE FROM GENERATOR. FAILURE TO DO SO
CAN RESULT IN INJURY.
CAUTION: Never force a belt over a pulley rim
using a screwdriver. The synthetic fiber of the belt
can be damaged.
CAUTION: When installing a serpentine accessory
drive belt, the belt MUST be routed correctly. The
water pump will be rotating in the wrong direction if
the belt is installed incorrectly, causing the engine
to overheat. Refer to belt routing label in engine
compartment, or refer to Belt Schematics in Cooling
System.
(1) Disconnect and isolate negative battery cable.
(2) Remove generator drive belt. Refer to Cooling
System for procedure.
(3) Raise and support vehicle.
(4) Remove protective plastic cover from B+ stud
at top of generator.
(5) Remove nut securing battery output cable to
B+ terminal at top of generator.
(6) Unplug field terminal connector at rear of gen-
erator.
(7) Remove 4 generator mounting bolts (Torx-style
#12 bit) (Fig. 1).
(8) Remove generator from lower side of vehicle.

been locked down.
REMOVAL
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, or instrument panel component diagno-
sis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for
the system capacitor to discharge before perform-
ing further diagnosis or service. This is the only
sure way to disable the supplemental restraint sys-
tem. Failure to take the proper precautions could
result in accidental airbag deployment.
CAUTION: The following procedure is for replace-
ment of an ineffective and unresponsive Instrument
Cluster (IC) with a new unit. If the IC is ineffective
or damaged but still responsive, it may be replaced
using an automatic replacement procedure that will
upload IC parameterization data from the existing IC
to the diagnostic scan tool, then download that data
to the new IC. Refer to the MISCELLANEOUS FUNC-
TIONS menu item under the IC module in the diag-
nostic scan tool, then select MODULE AUTO
REPLACEMENT and follow the scan tool prompts to
replace the IC. Do not lock down the IC until all of
the steps are followed and completed or the new IC
may be irreversibly damaged. This procedure initial-
izes and configures the IC for certain optional
equipment on the vehicle without the need for per-
forming a separate cluster programming procedure.
Failure to correctly parameterize the IC prior to it
being electronically locked down will result in the
IC being incorrectly and irreversibly configured for
improper vehicle equipment options, which will
require the IC be replaced again with another new
and unused unit to resolve.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the cluster bezel from the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
CLUSTER BEZEL - REMOVAL).
(3) Remove the cluster top cover from the instru-
ment panel. (Refer to 23 - BODY/INSTRUMENT
PANEL/TOP COVER - CLUSTER - REMOVAL).
(4) Remove the two screws that secure the instru-
ment cluster mounting ears to the instrument panel
base structure (Fig. 4).(5) Roll the top of the instrument cluster rearward
far enough to access and release the latch that
secures the Remote Keyless Entry (RKE)/immobilizer
module to the back of the instrument cluster rear
cover and disengage the module from the cluster

that is cut, frayed, or torn. Straighten any belt that
is twisted. Tighten any loose fasteners. Replace any
belt that has a damaged or inoperative buckle or
retractor. Replace any belt that has a bent or dam-
aged latch plate or anchor plate. Never attempt to
repair a seat belt component. Always replace dam-
aged or faulty seat belt components with the cor-
rect, new and unused replacement parts listed in
the DaimlerChrysler Mopar Parts Catalog.
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death on
vehicles equipped with airbags, before performing
any welding operations disconnect and isolate the
battery negative (ground) cable and disconnect all

WARNING: To avoid personal injury or death, do not
attempt to dismantle an airbag unit or tamper with
its inflator. Do not puncture, incinerate, or bring
into contact with electricity. Do not store at temper-
atures exceeding 93É C (200É F). An airbag inflator
unit may contain sodium azide and potassium
nitrate. These materials are poisonous and
extremely flammable. Contact with acid, water, or
heavy metals may produce harmful and irritating
gases (sodium hydroxide is formed in the presence
of moisture) or combustible compounds. An airbag
inflator unit may also contain a gas canister pres-
surized to over 2500 psi.WARNING: To avoid personal injury or death, when
handling a seat belt tensioner retractor, proper care
should be exercised to keep fingers out from under
the retractor cover and away from the seat belt
webbing where it exits from the retractor cover.
WARNING: To avoid personal injury or death,
replace all restraint system components only with
parts specified in the DaimlerChrysler Mopar Parts
Catalog. Substitute parts may appear interchange-
able, but internal differences may result in inferior
occupant protection.
WARNING: To avoid personal injury or death, the
fasteners, screws, and bolts originally used for the
restraint system components must never be
replaced with any substitutes. These fasteners have
special coatings and are specifically designed for
the restraint system. Any time a new fastener is
needed, replace it with the correct fasteners pro-
vided in the service package or specified in the

STANDARD PROCEDURE - VERIFICATION TEST
The following procedure should be performed using
a diagnostic scan tool to verify proper supplemental
restraint system operation following the service or
replacement of any supplemental restraint system
component.
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to dischargebefore performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
(1) During the following test, the battery negative
cable remains disconnected and isolated, as it was
during the supplemental restraint system component
removal and installation procedures.
(2) Be certain that the diagnostic scan tool con-
tains the latest version of the proper diagnostic soft-
ware. Connect the diagnostic to the 16-way Data
Link Connector (DLC). The DLC is located on the
dash panel beneath the driver side lower edge of the
instrument panel, outboard of the steering column
(Fig. 5).
(3) Turn the ignition switch to the On position and
exit the vehicle with the diagnostic scan tool.
(4) Check to be certain that nobody is in the vehi-
cle, then reconnect the battery negative cable.
(5) Using the diagnostic, read and record the
active (current) Diagnostic Trouble Code (DTC) data.
(6) Next, use the diagnostic to read and record any
stored (historical) DTC data.
(7) If any DTC is found in Step 5 or Step 6, refer
to the appropriate diagnostic information.
(8) Use the diagnostic to erase the stored DTC
data. If any problems remain, the stored DTC data
will not erase. Refer to the appropriate diagnostic
information to diagnose any stored DTC that will not
erase. If the stored DTC information is successfully
erased, go to Step 9.
(9) Turn the ignition switch to the Off position for
about fifteen seconds, and then back to the On posi-
tion. Observe the airbag indicator in the instrument
cluster. It should illuminate for four seconds, and
then go out. This indicates that the supplemental

(6) Disconnect the two clockspring lower pigtail
connectors from the vehicle wire harness connectors
located between the steering column and the back of
the fuse block underneath the steering column (Fig.
16).
(7) Loosen the two screws that secure the clock-
spring to the multi-function switch housing far
enough to engage the clearance holes in the clock-
spring rotor and to disengage the clockspring case
from the switch housing.
(8) Remove the clockspring from the multi-function
switch housing. The clockspring cannot be repaired.
It must be replaced if faulty or damaged, or if the
driver airbag has been deployed.
(9) If the removed clockspring is to be reused, be
certain that the clockspring rotor is secured to the
clockspring case to maintain clockspring centering
until it is reinstalled on the steering column. If clock-
spring centering is not maintained, the clockspring
must be centered again before it is reinstalled. (Refer
to 8 - ELECTRICAL/RESTRAINTS/CLOCKSPRING -
STANDARD PROCEDURE - CLOCKSPRING CEN-
TERING).
INSTALLATION
The clockspring cannot be repaired. It must be
replaced if faulty or damaged, or if the driver airbag
has been deployed.
If the clockspring is not properly centered in rela-
tion to the steering wheel, steering shaft and steer-
ing gear, it may be damaged. (Refer to 8 -
ELECTRICAL/RESTRAINTS/CLOCKSPRING -
STANDARD PROCEDURE - CLOCKSPRING CEN-
TERING). Service replacement clocksprings are
shipped pre-centered and with the mounting screws
backed out from the case far enough to engage the
access holes in the upper surface of the rotor. Theclockspring mounting screws should not be tightened
into the clockspring case until the clockspring has
been installed on the steering column. If the screws
are tightened into or removed from the case before
the clockspring is installed on a steering column, the
clockspring centering procedure must be performed.
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
NOTE: Before starting this procedure, be certain
that the front wheels are still in the straight-ahead
position.
(1) Carefully slide the centered clockspring down
over the steering column upper shaft until the screws
in the clockspring case are aligned with the mount-
ing holes on the multi-function switch housing.
(2) Tighten the two screws that secure the clock-
spring to the multi-function switch mounting hous-
ing. Tighten the screws to 2 N´m (18 in. lbs.).
(3) Reconnect the two clockspring lower pigtail
connectors to the vehicle wire harness connectors
located between the steering column and the back of
the fuse block underneath the steering column (Fig.

sealed within the airbag inflator. Typically, all poten-
tially hazardous chemicals are burned during an air-
bag deployment event. The inert gas that is produced
when the chemicals are burned is harmless. How-
ever, a small amount of residue from the burned
chemicals may cause some temporary discomfort if it
contacts the skin, eyes, or breathing passages. If skin
or eye irritation is noted, rinse the affected area with
plenty of cool, clean water. If breathing passages are
irritated, move to another area where there is plenty
of clean, fresh air to breath. If the irritation is not
alleviated by these actions, contact a physician.
REMOVAL
The following procedure is for replacement of a
faulty or damaged driver airbag. If the airbag is
faulty or damaged, but not deployed, review the rec-
ommended procedures for handling non-deployed
supplemental restraints. (Refer to 8 - ELECTRICAL/
RESTRAINTS - STANDARD PROCEDURE - HAN-
DLING NON-DEPLOYED SUPPLEMENTAL
RESTRAINTS). If the driver airbag has been
deployed, review the recommended procedures for
service after a supplemental restraint deployment
before removing the airbag from the vehicle. (Refer to
8 - ELECTRICAL/RESTRAINTS - STANDARD PRO-
CEDURE - SERVICE AFTER A SUPPLEMENTAL
RESTRAINT DEPLOYMENT).
WARNING: To avoid personal injury or death, on
vehicles equipped with airbags, disable the supple-
mental restraint system before attempting any
steering wheel, steering column, airbag, seat belt
tensioner, impact sensor, or instrument panel com-
ponent diagnosis or service. Disconnect and isolate
the battery negative (ground) cable, then wait two
minutes for the system capacitor to discharge
before performing further diagnosis or service. This
is the only sure way to disable the supplemental
restraint system. Failure to take the proper precau-
tions could result in accidental airbag deployment.
WARNING: To avoid personal injury or death, when
removing a deployed airbag, rubber gloves, eye
protection, and a long-sleeved shirt should be
worn. There may be deposits on the airbag cushion
and other interior surfaces. In large doses, these
deposits may cause irritation to the skin and eyes.
(1) Disconnect and isolate the battery negative
cable. Wait two minutes for the system capacitor to
discharge before further service.
(2) From the underside of the steering wheel,
remove the two screws that secure the driver airbag
to the horn switch armature within the hub cavity of
