CLEANING - ALUMINUM WHEEL CARE
Chrome plated and painted aluminum wheels
should be cleaned regularly using mild soap and
water to maintain their luster and to prevent corro-
sion.
Care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent
damage to the wheels. Any of the ªDO NOT USEº
items listed below WILL damage chrome plated and
painted aluminum wheels.
DO NOT USE:
²any abrasive metal cleaner
²any abrasive cleaning pad or brush
²any cleaner that contains an acid (this will
immediately react with and discolor the chromium
surface)
²chrome polish (unless it is buffed off immedi-
ately after application)
²oven cleaner
²a car wash that uses carbide-tipped wheel clean-
ing brushes

WHEEL COVER
DESCRIPTION
This vehicle uses a bolt-on type wheel cover (Fig.
25).
This bolt-on wheel cover cannot be removed from
the wheel until three of the five wheel mounting nuts
shown are removed (Fig. 25). The bolt-on wheel cover
can then be removed with the remaining two wheel
nuts tightened in place.
REMOVAL
(1) Noting the location of the valve stem in rela-
tionship to the wheel mounting nuts, remove the
three wheel mounting nuts securing the wheel cover
to the wheel and hub (Fig. 25).
CAUTION: When removing the wheel cover, do not
pry the wheel cover from the wheel. This can result
in damage to the wheel cover. The wheel cover is
removed by pulling it off the wheel by hand.
(2) Grasp the wheel cover at the edges in line with
the remaining installed wheel nuts and pull straight
outward from the wheel. This will pop the wheel
cover retaining tabs over the two remaining wheel
nuts, removing the wheel cover from the wheel.
INSTALLATION
NOTE: Wheel mounting nuts must be installed on
the studs as shown to allow installation of the
wheel cover (Fig. 26).
(1) Place the wheel cover on the wheel in the fol-
lowing fashion:
(a) Align the valve notch in the wheel cover with
the valve stem on the wheel.
(b) At the same time, align the two holes in the
wheel cover having the retaining tabs with the two
installed wheel nuts (Fig. 27).
(c) Press in on center of wheel cover until wheel
cover retaining tabs push past and engage rear of
previously installed wheel mounting nuts (Fig. 27).
This will hold the wheel cover in place.

(2) Install andlightly tightenthe three remain-
ing wheel mounting nuts, securing the wheel cover in
place (Fig. 25).

proper sequence (Fig. 28). Tighten wheel nuts to a
torque of 135 N´m (100 ft. lbs.).
WHEEL MOUNTING STUDS -
FRONT
REMOVAL
CAUTION: If a wheel mounting stud needs to be
replaced in the hub and bearing assembly, the
studs MUST NOT be hammered out of the hub
flange. If a stud is removed by hammering it out of
the bearing flange, damage to the hub and bearing
assembly will occur leading to premature bearing
failure.
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. See Hoisting in Lubrication
and Maintenance.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the two adapter mounting bolts secur-
ing both the disc brake caliper adapter to the steer-
ing knuckle (Fig. 29).
(4) Remove the disc brake caliper and adapter as
an assembly from the steering knuckle (Fig. 29).
Hang the assembly out of the way using wire or a
bungee cord. Use care not to overextend the brake
hose when doing this.
(5) Remove brake rotor from hub by pulling it
straight off wheel mounting studs (Fig. 29).
(6) On the wheel mounting stud to be removed,
install a wheel mounting (lug) nut far enough so the
threads on the stud are even with end of nut. Install
Remover, Special Tool C-4150A on hub and bearing
assembly flange and wheel stud (Fig. 30).
(7) Tighten down on special tool, pushing wheel
stud out of the hub flange. When shoulder of wheel
stud is past flange, remove special tool from hub and
bearing. Remove nut from stud and remove stud
from hub flange.

bearing (Fig. 29).
(4) Install brake caliper and adapter back over
brake rotor aligning adapter with mounting holes on
steering knuckle (Fig. 29).
(5) Install the two adapter mounting bolts securing
the adapter to the steering knuckle. Tighten the
mounting bolts to 169 N´m (125 ft. lbs.) torque.

3.2.3 OTHER CONTROLS
CHARGING SYSTEM
The charging system is turned on when the
engine is started and ASD relay energized. When
the ASD relay is on, ASD output voltage is supplied
to the ASD sense circuit at the PCM. This voltage is
connected in some cases, through the PCM and
supplied to one of the generator field terminals
(Gen Source +). All others, the Gen field is con-
nected directly to the ASD output voltage. The
amount of current produced by the generator is
controlled by the Electronic Voltage Regulator
(EVR) circuitry, in the PCM. Battery temperature is
determined from IAT. This temperature along with
sensed line voltage, is used by the PCM to vary the
battery charging rate. This is done by cycling the
ground path to the other generator field terminal
(Gen field driver).
SPEED CONTROL SYSTEM
The PCM controls vehicle speed by operation of
the speed control servo vacuum and vent solenoids.
Energizing the vacuum solenoid applies vacuum to
the servo to increase throttle position. Operation of
the vent solenoid slowly releases the vacuum allow-
ing throttle position to decrease. A special dump
solenoid allows immediate release of throttle posi-
tion caused by braking, cruise control switch turned
off, shifting into neutral, excessive RPM (tires spin-
ning) or ignition off.
LEAK DETECTION PUMP SYSTEM (IF EQUIPPED)
The leak detection pump is a device that pressur-
izes the evaporative system to determine if there
are any leaks. When certain conditions are met, the
PCM will activate the pump and start counting
pump strokes. If the pump stops within a calibrated
number of strokes, the system is determined to be
normal. If the pump does not stop or stops too soon,
a DTC will be set.
3.2.4 PCM OPERATING MODES
As input signals to the PCM change, the PCM
adjusts its response to output devices. For example,
the PCM must calculate a different injector pulse
width and ignition timing for idle than it does for
wide open throttle. There are several different
modes of operation that determine how the PCM
responds to the various input signals.
There are two types of engine control operation:
open loopandclosed loop.
Inopen loopoperation, the PCM receives input
signals and responds according to preset program-
ming. Inputs from the heated oxygen sensors are
not monitored.Inclosed loopoperation, the PCM monitors the
inputs from the heated oxygen sensors. This input
indicates to the PCM whether or not the calculated
injector pulse width results in the ideal air-fuel
ratio of 14.7 parts air to 1 part fuel. By monitoring
the exhaust oxygen content through the oxygen
sensor, the PCM can fine tune injector pulse width.
Fine tuning injector pulse width allows the PCM to
achieve the lowest emission levels while maintain-
ing optimum fuel economy.
The engine start-up (crank), engine warm-up,
and wide open throttle modes are open loop modes.
Under most operating conditions, closed loop modes
occur with the engine at operating temperature.
IGNITION SWITCH ON (ENGINE OFF) MODE
When the ignition switch activates the fuel injec-
tion system, the following actions occur:
1. The PCM determines atmospheric air pressure
from the MAP sensor input to determine basic
fuel strategy.
2. The PCM monitors the engine coolant tempera-
ture sensor and throttle position sensor input.
The PCM modifies fuel strategy based on this
input.
When the key is in the on position and the engine
is not running (zero rpm), the auto shutdown relay
and fuel pump relay are not energized. Therefore,
voltage is not supplied to the fuel pump, ignition
coil, and fuel injectors.
Engine Start-up ModeÐ This is an open loop
mode. The following actions occur when the starter
motor is engaged:
1. The auto shutdown and fuel pump relays are
energized. If the PCM does not receive the cam-
shaft and crankshaft signal within approxi-
mately one second, these relays are de-
energized.
2. The PCM energizes all fuel injectors until it
determines crankshaft position from the cam-
shaft and crankshaft signals. The PCM deter-
mines crankshaft position within one engine
revolution. After the camshaft position has been
determined, the PCM energizes the fuel injectors
in sequence. The PCM adjusts the injector pulse
width and synchronizes the fuel injectors by
controlling the fuel injectors' ground paths.
3. Once the engine idles within 64 rpm of its target
engine speed, the PCM compares the current
MAP sensor value with the value received dur-
ing the ignition switch on (zero rpm) mode. A
diagnostic trouble code is written to PCM mem-
ory if a minimum difference between the two
values is not found.
