GENERAL
INFORMATION
A rear wheel antilock brake system
is
standard
equipment
on all AD
models.
It is an
electronically operated system designed
to
retard rear wheel lockup
during periods
of
high wheel slip
and
deceleration.
Retarding lockup
is
accomplished
by
modulating
fluid pressure
to the
rear brake units. Rear brake fluid apply pressure
is
modulated
ac­

cording
to
wheel speed, degree
of
wheel slip
and
rate
of deceleration.
A
sensor located
in the
rear axle
housing converts differential rotating speed into elec­
tronic signals.
The
signals
are
transmitted
to the
electronic brake control module
for
processing.
The

control unit determines rate
of
deceleration
and

wheel slip from these signals.
SYSTEM
COMPONENTS

Basic system components include
an
electronic
brake control module,
a
hydraulic pressure control
valve,
a
speed sensor
and
exciter ring
and an
anti- lock warning lamp (Fig.
1).
A standard master cylinder
and
vacuum power
brake booster
are
used
for all
applications.

ANTILOCK ELECTRONIC CONTROL MODULE
The electronic module controls
all
phases
of
anti-
lock mode brake operation.
The
module
is
separate
from other electrical circuits
in the
vehicle
and
oper­ ates independently.
The module
is
located
on the
passenger side cowl
panel under
the
dash
(Fig.
2).
The
system hydraulic
valve, speed sensor
and
indicator lamps
are all in cir-

Isolation/Dump
Valve Cycle Times
Activation (opening/closing) of the isolation and
dump valves is continuous during antilock operation.
The valves cycle rapidly in response to speed sensor inputs and control module signal commands. Cycle
times are measured in milliseconds.
As the demand for antilock mode brake operation
is decreased, the module deactivates the hydraulic
valve components to restore normal brake operation.

ANTILOCK
SERVICE
DIAGNOSIS
GENERAL INFORMATION An antilock system malfunction will be indicated
by illumination of the amber antilock warning lamp.
The red brake warning lamp may also illuminate.
If a problem occurs, system diagnosis should begin
with a fluid level check followed by a visual exami­
nation of the system electrical and hydraulic connec­

tions.
If obvious defects (low fluid, leaks, loose connections, etc.) are not evident, road test the vehi­

cle.
A road test should help determine if a malfunc­
tion is actually related to an antilock component.
During the road test, note if other conditions are
evident such as a low pedal, pull, grab, or similar condition. Remember that brake malfunctions such as low fluid, system leaks, parking brakes partially
applied, will also affect the antilock system. The idea
is to determine if a malfunction is actually related to
an anti-lock component.
If a road test does reveal a problem, repeat the
road test with the owner driving. Make sure the owner is not riding the brake pedal, or has forgotten
to release the parking brakes. Either situation will
generate a fault and cause the antilock light to illu­
minate.

SYSTEM FAULT
CODES
The antilock control module generates flash codes
to help identify the cause of an antilock system fault. Two different control modules are used with the
1992/1993 RWAL system. A type I module is used in
some early production models. All remaining produc­
tion models are equipped with a type II module. The type I and II modules are identified by the way
fault codes 9 and 11 are processed. If the vehicle has a type I module, codes 9 and 11 are not erased when
the ignition switch is turned to Off position. If the vehicle has a type II module, codes 9 and 11 are
erased when the switch is turned to Off.
FAULT CODES WITH TYPE I CONTROL
MODULE
The microprocessor in the electronic control module
has a memory and a self test feature. The self test
feature is activated whenever the ignition switch is
turned to Accessory or Run position. If a system fault is detected, the control module il­
luminates the antilock light and stores the fault code
in memory. Fault codes are retained in memory even after turning the ignition switch to Off position.
FAULT CODES WITH TYPE II CONTROL
MODULE The microprocessor in the electronic control module
has a memory and a self test feature. The self test
feature is activated whenever the ignition switch is
turned to Accessory or Run position.
If a system fault is detected, the control module
will illuminate the antilock indicator lamp and store
fault codes 1 through 8, 10 and 12 through 15 in the
microprocessor memory. When one of these fault
codes is generated, the control module will retain the code after the ignition switch is turned to the Off po­
sition.
When fault code 9 is generated, the code only re­
mains in microprocessor memory while the ignition switch is in Run position. Turning the ignition
switch to Off position erases fault code 9. However, if
the problem still exists when the switch is turned
back to Run position, code 9 will reappear in memory after 20 seconds and the antilock light will illumi­
nate once again.
When fault code 11 is generated, the antilock light
will illuminate when vehicle speed exceeds approxi­ mately 60.35 km/h (37.5 mph). Code 11 only remains in memory while the ignition switch is in the Run
position and the fault is present.
When the cause of a fault code 11 is corrected, the
antilock light goes off. Code 11 is erased when the ig­
nition switch is turned to Off position. However, if
the problem cause still exists when the ignition switch is turned to Run position, code 11 will reap­
pear when vehicle speed exceeds approximately 60.35 km/h (37.5 mph).

FAULT
CODE
CAPACITY
The microprocessor memory will store and display
only one fault code at a time. The stored code can be
displayed by grounding the RWAL diagnostic connec­
tor.

FAULT
CODE
IDENTIFICATION
To determine what the fault code is, momentarily
ground the RWAL diagnostic connector and count
the number of times the amber antilock lamp flashes. Fault codes and typical malfunctions are out­lined in Figure 8. Note that when a fault code is gen­
erated, the red brake warning lamp will also
illuminate. The initial flash will be a long flash followed by a
number of short flashes. The long flash indicates the
beginning of the fault number sequence and the short flashes are a continuation of that sequence.

and rapid wear. Tighten the cover bolts as described
in the Clutch Service section.
Improperly seated flywheels and clutch housings
are other causes of clutch failure. Improper seating
will produce misalignment and subsequent clutch problems.
Tighten the clutch housing bolts to proper torque
before installing any struts. Also be sure the align­ ment dowels are in place and seated in the block and
housing beforehand.
The use of non-standard or low quality parts can
also lead to problems and wear. Use the recom­
mended factory quality parts to avoid comebacks.

INSPECTION AND DIAGNOSIS CHARTS
The clutch inspection chart (Fig. 8) outlines items
to be checked before and during clutch installation. Use the chart as a check list to help avoid overlook­ing potential problem sources during service opera­

tions.
The diagnosis charts describe common clutch prob­

lems,
causes and correction. Fault conditions are
listed at the top of each chart. Conditions, causes and
corrective action are outlined in the indicated col­

umns.
The charts are provided as a convenient reference
when diagnosing faulty clutch operation.

FLYWHEEL SERVICE
Inspect the flywheel whenever the clutch disc,
cover and housing are removed for service. Check
condition of the flywheel face, hub, ring gear teeth,
and flywheel bolts. Minor scratches, burrs, or glazing on the flywheel
face can be scuff sanded with 180 grit emery cloth. However, the flywheel should be replaced if the disc
contact surface is severely scored, heat checked,
cracked, or obviously worn. Cleanup of minor flywheel scoring should be per­
formed with surface grinding equipment. Remove
only enough material to reduce scoring (approximate­
ly 0.001 - 0.003 in.). Heavy stock removal is not rec­
ommended. Replace the flywheel if scoring is severe
and deeper than 0.076 mm (0.003 in.). Excessive
stock removal can result in flywheel cracking or
warpage after installation; it can also weaken the flywheel and interfere with proper clutch release. Check flywheel runout if misalignment is sus­
pected. Runout should not exceed 0.08 mm (0.003
in.).
Measure runout at the outer edge of the fly­
wheel face with a dial indicator. Mount the dial in­
dicator on a stud installed in place of one of the
flywheel attaching bolts. Clean the crankshaft flange before mounting the
flywheel. Dirt and grease on the flange surface may cock the flywheel causing excessive runout. Check condition of the flywheel hub and attaching

bolts.
Replace the flywheel if the hub exhibits cracks in the area of the attaching bolt holes. Install new attaching bolts whenever the flywheel
is replaced and use Mopar Lock N' Seal, or Loctite
242 on replacement bolt threads.
Recommended flywheel bolt torques are:
• 75 N»m (55 ft. lbs.) for gas engine flywheels
• 137 N*m (101 ft. lbs.) for diesel flywheels Inspect the teeth on the starter ring gear. If the
teeth are worn or damaged, the flywheel should
be replaced as an assembly. This is the recom­ mended and preferred method of repair.
In cases where a new flywheel is not readily avail­

able,
a replacement ring gear can be installed. How­
ever, the following precautions must be observed to
avoid damaging the flywheel and replacement gear.
(a) Mark position of the old gear for alignment
reference on the flywheel. Use a scriber for this
purpose.
(b) Wear protective goggles or approved safety
glasses. Also wear heat resistent gloves when han­
dling a heated ring gear. (c) Remove the old gear by cutting most of the
way through it (at one point) with an abrasive cut­ off wheel. Then complete removal with a cold chisel
or punch. (d) The ring gear is a shrink fit on the flywheel.
This means the gear must be expanded by heating in order to install it. The method of heating and expanding the gear is extremely important. Ev­
ery surface of the gear must be heated at the same
time to produce uniform expansion. An oven or
similar enclosed heating device must be used. Tem­
perature required for uniform expansion is 325-350° F.

CAUTION:
Never
use an
oxy/acetylene torch
to re­
move
the old
gear,
or to
heat
and
expand
a new

gear.
The
high temperature
of the
torch flame
will

cause
localized heating
and
damage
the
flywheel.
In

addition,
using
the
torch
to
heat
a
replacement gear

will
cause uneven heating
and
expansion.
The
torch
flame
will
also
anneal
the
gear
teeth
resulting
in
rapid wear
and
damage
after
installation.

(e) The heated gear must be installed evenly to
avoid misalignment or distortion. A shop press and
suitable press plates should be used to install the
gear if at all possible.
(f) Be sure to wear eye and hand protection.
Heat resistent gloves and safety goggles are needed
for personal safety. Also use metal tongs, vise
grips,
or similar tools to position the gear as neces­sary for installation.
(g) Allow the flywheel and ring gear to cool
down before installation. Set the assembly on a
workbench and let it cool in normal shop air.

CAUTION:
Do not
use water,
or
compressed
air to

cool
the
flywheel.
The
rapid cooling produced
by

water
or
compressed
air can
distort,
or
crack
the
gear
and
flywheel.

GENERAL
INFORMATION
The battery stores, stabilizes,
and
produces electri­
cal current.
A
battery must
be
able
to
accept
a

charge
and
produce high-amperage current over
an

extended period.
A
chemical reaction takes place
be­

tween sulfuric acid solution (electrolyte)
and
lead + /-
plates
in
each cell
of the
battery.
As the
battery discharges,
the
plates collect acid from
the
electro­

lyte.
When
the
charging system charges
the
battery,
water
is
converted
to
sulfuric acid
in the
battery.
The
amount
of
acid (specific gravity)
in the

CHARGING
A battery is completely charged when it has:
• an open circuit voltage of 12.4 volts or more.
• has enough cranking capacity (minimum 9.6 volts
when loaded for 15 seconds to 50% of cold cranking amperage rating at 21°C/70°F). A green color, in the test indicator on the top of the
battery, indicates the battery is charged enough for
further testing. A black color indicates the battery
voltage state of charge is below 75%. A yellow or
bright color indicates the battery has excessively low electrolyte level. The battery cannot be refilled or
charged, it must be replaced.
