The Powertrain Control Module (PCM) is given
responsibrlity for the operation of the emission con-
trol devices, cooling fans, ignition and advance and
in some cases, automatic transaxle functions. Be-
cause the PCM oversees both the ignition timing and
the fuel injection operation, a precise air/fuel ratio
will be maintained under all operating conditions,
The PCM is a microprocessor, or small computer,
which receives electrical inputs from several sensors,
switches and relays on and around the engine.
Based on combinations of these inputs, the PCM
controls outputs to various devices concerned with
engine operation and emissions. The control module
relies on the signals to form a correct picture of cur-
rent vehicle operation. If any of the input signals is
incorrect, the PCM reacts to whatever picture is
painted for it. For example, if the coolant temperature
sensor is inaccurate and reads too low, the PCM may
see a picture of the engine never warming up. Conse-
quently, the engine settings will be maintained as if
the engine were cold. Because so many inputs can
affect one output, correct diagnostic procedures are
essential on these systems,
One part of the PCM is devoted to monitoring
both input and output functions within the system.
This ability forms the core of the self-diagnostic sys-
tem. If a problem is detected within a circuit, the con-
trol module will recognize the fault, assign it a Diag-
nostic Trouble Code (DTC), and store the code in
memory. The stored code(s) may be retrieved during
diagnosis. While the OBD-II system is capable of recognizing
many internal faults, certain faults WIII not be recog-
nized. Because the control module sees only electri-
cal signals, it cannot sense or react to mechanical or
vacuum faults affecting engine operation. Some of
these faults may affect another component which will
set a code. For example, the PCM monitors the out-
put signal to the fuel injectors, but cannot detect a
partially clogged injector. As long as the output dri-
ver responds correctly, the computer will read the
system as functioning correctly. However, the im-
proper flow of fuel may result in a lean mixture. This
would, in turn, be detected by the oxygen sensor and
noticed as a constantly lean signal by the PCM. Once
the signal falls outside the pre-programmed limits,
the control module would notice the fault and set a
trouble code.
Additionally, the OBD-II system employs adaptive
fuel logic. This process is used to compensate for
normal wear and variability within the fuel system.
Once the engine enters steady-state operation, the
control module watches the oxygen sensor signal for
a bias or tendency to run slightly rich or lean. If such
a bias is detected, the adaptive logic corrects the fuel
delivery to bring the air/fuel mixture towards a cen-
tered or 14.7:1 ratio. This compensating shift is
stored In a non-volatile memory which is retained by
battery power even with the ignition switched
OFF. The correction factor is then available the next time
the vehicle is operated.

Reading the control module memory is on of the
first steps in OBD II system diagnostics. This step
should be initially performed to determine the general
nature of the fault. Subsequent readings will deter-
mine if the fault has been cleared.
Reading codes can be performed by any of the
methods below:
l Read the control module memory with the
Generic Scan Tool (GST)
l Read the control module memory with the ve-

To read the fault codes, connect the scan tool or

To install:
6. Apply multi-purpose grease to the shafts,
grease sumps, dust seal lips and needle roller bear-
ings of the replacement U-joint Do not apply exces-
sive grease Otherwse, faulty fitting of bearing caps
and errors in selection of snaprings may result.
7. Press fit the journal bearings to the yoke using
a C-clamp as follows:
a. Install a solid base onto the bottom of the
C-clamp.
b. Insert both bearings into the yoke. Hold
and press fit them by tightening the C-clamp.
c. Install snaprings of the same thickness
onto both sides of each yoke.
d. Press the bearing and journal into one side, using a brass bar with diameter of 0.59 in.
(15mm).
8. Measure the clearance between the snapring
and the groove wall of the yoke with a feeler gauge. If
the clearance exceeds 0.0008-0.0024 in.
(0.02-O.O6mm), the snap rings should be replaced.
DRIVESHAFT BALANCING
Driveshaft balancing is a process best left for a
professional wrth the proper equipment. Makeshift
methods using hose clamps or similar devices can
work, but the process of correcting the imbalance in
this manner is very tough and extremely time con-
suming.
Many machine shops can balance driveshafts;
some parts stores and jobbers can also balance dri-
veshafts using outside contractors.

the center bearing bracket mating mark.
8. Assemble the center bearing to the center
propeller shaft and rear propeller shaft. Face the side
onto which the center bearing bracket mating marks
IS placed and the dust seal is installed toward the
side of the center propeller shaft and rear propeller
shaft.
9 Apply a thin and even coat of the grease, en-
closed with the repair kit, to the rubber packing on
the companion flange. Align the mating marks on the
center propeller shaft and the companion flange, then
press fit the center bearing with self-locking nuts.

The 4-Wheel Anti-lock Brake System (ABS) is an
electronically operated, all wheel brake control sys-
tem. Major components include the vacuum power
brake booster, master cylinder, the wheel speed sen-
sors, the Hydraulic Control Unit (HCU), Anti-lock
control unit, a relay, and on the AWD Galant, a G sen-
sor.
The system is designed to retard wheel lockup
during periods of high wheel slip when braking. Re-
tarding wheel lockup is accomplished by modulating
fluid pressure to the wheel brake units. When the
control unit detects a variation in voltage across the
wheel speed sensors, the ABS is activated. The con-
trol unit opens and closes various valves located in-
side the HCU. These valves, called dump and isola-
tion valves, modulate the hydraulic pressure to the
wheels by applying and venting the pressure to the
brake fluid circuits.
PRECAUTIONS
l Certain components within the Anti-Lock Brake
System (ABS) are not intended to be serviced or re-
paired individually. Only those components with re- !
moval and installation procedures should be ser-
viced.
0 Do not use rubber hoses or other parts not
specifically specified for an ABS system. When using
repair kits, replace all parts included in the kit. Partial
or incorrect repair may lead to functional problems
and require the replacement of components.
l Lubricate rubber parts with clean, fresh brake
fluid to ease assembly. Do not use lubricated shop air
to clean parts; damage to rubber components may re-
sult.
l Use only specified brake fluid from an un-
opened container.
l If any hydraulic component or line is removed
or replaced, it may be necessary to bleed the entire
system.
l A clean repair area is essential. Always clean
the reservoir and cap thoroughly before removing the
cap. The slightest amount of dirt in the fluid may plug
an orifice and impair the system function. Perform re-
pairs after components have been thoroughly
cleaned; use only denatured alcohol to clean compo-
nents. Do not allow ABS components to come into
contact with any substance containing mineral oil;
this includes used shop rags.
l The Anti-Lock control unit is a microprocessor
similar to other computer units in the vehicle. Ensure
that the ignition switch is
OFF before removing or in-
stalling controller harnesses. Avoid static electricity
discharge at or near the controller.
l If any arc welding is to be done on the vehicle,
the control unit should be unplugged before welding
operations begin.
) See Figures 116 thru 123
The diagnosis of the ABS system is rather complex
and requires quite a few special tools including scan tools, special test harnesses and other special and
expensive tools. Alternative methods and common
sense can be substituted, however, We at Chilton feel
that it is beyond the scope of the average do-it-your-
selfer. If you experience the amber ANTI LOCK light
on in the instrument cluster of your vehicle, check the
fluid level in the master cylinder first. Low fluid level
will usually illuminate the red BRAKE lamp in the in-
strument cluster as well as, but not always, the amber
ANTI LOCK lamp in the instrument cluster. The low
fluid level could indicate a leak, but sometimes just
indicates low, worn brake linings that have caused the
caliper pistons and wheel cylinders to extend further,
and thus using more fluid to exert force on them. In-
spect the brake system for hydraulic fluid leaks and
also inspect the brake linings for excessive wear.
