ICU (INTEGRATED CONTROL
UNIT)
DESCRIPTION
The hydraulic control unit (HCU) and the control-
ler antilock brake (CAB) used with this antilock
brake system are combined (integrated) into one
unit, which is called the integrated control unit (ICU)
(Fig. 7). The ICU is located below the master cylinder
in the engine compartment (Fig. 8).
Two different ICU's (HCU and CAB) are used on
this vehicle depending on whether or not the vehicle
is equipped with traction control. The HCU on a
vehicle equipped with traction control has a valveblock that is approximately one inch longer than a
HCU on a vehicle that is equipped with ABS only.
The ABS-only ICU consists of the following compo-
nents: the CAB, eight (build/decay) solenoid valves
(four inlet valves and four outlet valves), valve block,
fluid accumulators, a pump, and an electric motor.
The ABS-with traction control ICU consists of the
following components: the CAB, eight (build/decay)
solenoid valves (four inlet valves and four outlet
valves), two traction control (ASR) valves, two
hydraulic shuttle valves, valve block, fluid accumula-
tors, a pump, and an electric motor.
The replaceable components of the ICU are the
HCU and the CAB. No attempt should be made to
service any individual components of the HCU or
CAB. For information on the CAB, (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/CONTROLLER ANTILOCK BRAKE -

MASTER CYLINDER - RHD
DESCRIPTION
The master cylinder used on right hand drive
(RHD) vehicles functions similarly to that used on
left hand drive (LHD) vehicles. The RHD master cyl-
inder, as well as the RHD power brake booster, is
located in the same area, but lower in the engine
compartment than LHD models (Fig. 1). For that
reason an extension manifold is placed between the
fluid reservoir and master cylinder housing allowing
the fluid reservoir to be positioned in the same loca-
tion as on LHD models.
REMOVAL
CAUTION: Vacuum in the power brake booster must
be pumped down (removed) before removing mas-
ter cylinder from power brake booster. This is nec-
essary to prevent the power brake booster from
sucking in any contamination as the master cylin-der is removed. This can be done simply by pump-
ing the brake pedal, with the vehicle's engine not
running, until a firm feeling brake pedal is achieved.
(1) With engine not running, pump brake pedal
until a firm pedal is achieved (4 or 5 strokes).
(2) Disconnect negative battery terminal.
(3) Disconnect positive battery terminal.
(4) Remove battery shield.
(5) Remove nut and clamp securing battery to tray,
remove battery.
(6) Thoroughly clean all surfaces of the brake fluid
reservoir and master cylinder. Use only solvent such
as MopartBrake Parts Cleaner or equivalent.
(7) Remove wiring harness connector from brake
fluid level switch in master cylinder brake fluid res-
ervoir (Fig. 1).
(8) Disconnect primary and secondary brake tubes
from master cylinder housing (Fig. 2). Install sealing
plugs in the now open brake tube outlet ports.
CAUTION: Before removing the master cylinder
from the power brake vacuum booster, the master
cylinder and vacuum booster must be thoroughly
cleaned. This must be done to prevent dirt particles
from falling into the power brake vacuum booster.
(9) Clean area where master cylinder assembly
attaches to power brake booster. Use only a solvent
such as MopartBrake Parts Cleaner or equivalent.
(10) Remove two nuts attaching master cylinder to
power brake booster (Fig. 2).
(11) Slide master cylinder straight out of power
brake booster.

DESCRIPTION
CLUTCH COMPONENTS
Models equipped with a 2.4L Gas engine utilize a
modular clutch assembly (Fig. 1). The modular clutch
consists of a single, dry-type clutch disc, a diaphragm
style clutch cover, and an integrated flywheel. The
clutch cover (pressure plate) is riveted to the fly-
wheel, and therefore can only be serviced as an
assembly.
Models equipped with the 2.5L Turbo Diesel engine
utilize a conventional clutch system (Fig. 2). This
system consists of a flywheel, clutch disc, and clutch
cover (pressure plate), which is fastened to the fly-
wheel, capturing the clutch disc within. Each compo-
nent is individually serviceable, however it ishighly
recommended that the clutch cover and disc be
replaced as a set.

RELEASE SYSTEM
Left-Hand Drive (LHD) models utilize a cable-actu-
ated clutch release system, consisting of a cable that
connects the clutch pedal to the clutch release lever
in the transaxle (Fig. 3) (Fig. 4). When the driver
depresses the clutch pedal, the clutch release cable
pulls the release lever (Fig. 5). This forces the release
bearing into the clutch diaphragm spring via lever-
age, releasing the clamping force on the clutch disc,
allowing the engine crankshaft to rotate indepen-
dently from the transaxle input shaft.
Right-Hand Drive (RHD) models utilize a hydraulic
clutch release system, conisting of a clutch master
cylinder attached to the clutch pedal (Fig. 6), and a
slave cylinder fastened to the transaxle which oper-
ates the clutch release lever (Fig. 7). When the driver
depresses the clutch pedal, the master cylinder push-
rod travels through the cylinder bore, displacing fluid
through the master cylinder plumbing. This fluid dis-
placement forces the slave cylinder piston to travel,
forcing the clutch release bearing into the clutch dia-
phragm spring via the release lever and leverage
(Fig. 8). This releases the clamping force on the
clutch disc, allowing the engine crankshaft to rotate
independently from the transaxle input shaft.
