* Vehicles equipped with a tire pressure monitoring system must be inspected for correct operation
using the diagnostic tool.
To maximize tire performance, inspect the tires for
signs of incorrect inflation and uneven wear which
may indicate a need for balancing, rotation or
suspension alignment. Tires should also be
checked frequently for cuts, stone bruises,
abrasions, blisters and for objects that may have
become embedded in the tread. More frequent
inspections are recommended when rapid or ( extreme temperature changes occur or when road
surfaces are rough or occasionally littered with
foreign material.
As a further visible check of tire condition, tread
wear indicators are molded into the bottom of the
tread grooves. When these indicator bands become
visible, new tires must be installed.
Tire Wear Diagnosis
Uneven wear is usually caused by either excessive
camber or excessive toe on tires.
Sometimes incorrect toe settings or worn struts will
cause severe 'cupping' or 'scalloped' tire wear on
non-driven wheels.
Severely incorrect toe settings will also cause other unusual wear patterns.
Tire Vibration Diagnosis
A tire vibration diagnostic procedure always begins
with a road test. The road test and customer
interview (if available) will provide much of the
information needed to find the source of a vibration. During
the road test, drive the vehicle on a road
that is smooth and free of undulations. If vibration
is apparent, note and record the following:
- the speed at which the vibration occurs.
- what type of vibration occurs in each speed
range.
- mechanical or audible
- how the vibration is affected by changes in the
following:
- engine torque
- vehicle speed
- engine speed
- type of vibration - sensitivity:
- torque sensitive
- vehicle speed sensitive
- engine speed sensitive
The following explanations help isolate the source
of the vibration.
Torque Sensitive
This means that the condition can be improved or
made worse by accelerating, decelerating,
coasting, maintaining a steady vehicle speed or
applying engine torque.
Vehicle Speed Sensitive
This means that the vibration always occurs at the
same vehicle speed and is not affected by engine
torque, engine speed or the transmission gear
selected.

Fail-Safe Cooling
The vehicle has a strategy built into the powertrain
control module (PCM) that will control the engine
if the engine starts to overheat.
If the engine starts to overheat, stage

a signal to the PCM which then moves the
temperature gauge pointer into the red zone.
If the engine is not switched off and the
temperature continues to rise, the malfunction

to the driver that the engine is approaching critical
limits and should stop. At this point DTC

If the MIL and temperature gauge are ignored by
the driver, stage 2 of the strategy will commence.
The PCM will start to control the engine by cutting
out two cylinders and restricting the RPM to below
3000 RPM. The MIL will remain illuminated. This

Cold start
To overcome the problems relating to cold start
inherent with Ethanol E85 vehicles (temperatures
down to -29 degrees centigrade), a block heater
has been installed into the engine coolant system.
The block heater is located to the rear of the engine
under the exhaust manifold. The block heater is
fitted with a dedicated harness which terminates at an external plug connector fitted into the radiator
grill.

REFER to: Acceleration Control (31
0-02A,
Diagnosis and Testing).
European On-Board Diagnostics (EOBD)
EOBD is a diagnostic system integrated into the
powertrain control module (PCM). This system
continuously monitors vehicle emission
components. The system includes a malfunction
indicator lamp (MIL) which indicates when there is
a concern that can affect emissions or the system
malfunctions. Data stored within the module DTC
memory can be accessed using a generic scan
tool or WDS.
EOBD is mandated within European Union
regulations from the year 2000 for passenger
vehicles with petrol engines and from 2003 onwards for passenger vehicles with diesel
engines.
EOBD Functions:
Establishes when and how emissions control
faults must be indicated.
Actuates emission control malfunction indicator
lamp (MIL) and fault memory.
Indicates operating conditions in which the
concern occurred (freeze frame data).
Standardized output of operating data such as
engine speed, engine coolant temperature etc.
Standardized names and abbreviations for
components and systems.
Standardized
DTCs for all manufacturers.
Standardized communication with the diagnostic
equipment.
Standardized 16-pin data link connector (DLC)
in area of the instrument panel.
Concern display must be possible using a
generic scan tool.
EOBD consists of the following elements:
Warm-up Cycle C'
The warm-up cycle is an operation that consists of
key on, engine start and a coolant temperature
increase of
22"C, exceeding 71 OC on completion.
Drive Cycle
A drive cycle commences when the engine is
started (cold or warm) and ends when the engine
is switched off.
Trip
A trip begins when the engine is started and is
complete when all the EOBD monitors have
completed a self-test. This may take place over a
number of drive cycles. On diesel variants, the
information gathered from one drive cycle is not
carried over to a subsequent cycle or cycles.
When a concern has been rectified, particularly
after electronic engine control components have
been changed, the DTC memory, which is part of
the EEPROM must be cleared of all trouble codes.
When the DTC memory has been cleared, the code
.
PI000 (known as the readiness code) is set in the
PCM memory, which indicates that since the
EEPROM has been cleared, not all of the
monitoring systems have completed their tests.
PI000 can only be cleared by carrying out a trip,
which includes driving the vehicle under variable
conditions of speed, load and time so that all of the
monitors are completed. As
PI000 will not
illuminate the MIL it is not necessary to carry out
the trip before returning the vehicle to the customer.
Freeze Frame Data
When a concern is detected, various data is stored
depending on application including:
Diagnostic trouble code.
Vehicle speed.
Engine coolant temperature.
Engine speed.
Engine load.
Mixture formation trim value (trim value for
engine wear) (All except vehicles with diesel
engine).
State of oxygen sensor control (open and closed

sensors. It will detect deviations in airlfuel ratios
(AFR) and sensor faults.
The
H02S will cause emission increase when its
response time increases too much. To diagnose
a sensor a period is measured and the number of
leanlrich transitions are counted. The sum of valid
periods is then calculated. To avoid
non-representative measurements, the period is
valid only if the
H02S has been below a low
threshold and above a high threshold between 2
consecutive leanlrich transitions.
A failure is
declared when the sum of the measured periods
exceeds the sum of the corresponding limit (held
within the PCM) and the MIL is illuminated.
Catalytic Converter Efficiency Monitor (All except
vehicles with diesel engine)
The efficiency of a catalytic converter is measured
by its ability to store and later release oxygen to
convert harmful gases. The efficiency is reduced
if the converter becomes contaminated as it ages,
and at high gas flow rates, because the exhaust
gas does not remain in the converter long enough
to complete the conversion process. switches
over or until the end of a delay. If this
delay expires or the sensor does not switch, the
sensor is treated as failed.
Combustion Noise Monitor (Vehicles with common
rail fuel injection)
In diesel variants, the Combustion Noise Monitor
is used to trim the fuel injection pulse lengths. Each
fuel injector has an associated set of correction
data that is determined during a production end of
line test. The Combustion Noise Monitor is used
to determine how the fuel injector characteristic
changes from this initial calibration over the life of
the fuel injector.
EGR Monitor (Vehicles with diesel engine)
The functionality of the EGR system is checked by
comparing either the MAP sensor output or EGR
valve lift potentiometer output (depending upon
application) with expected values.
Diagnostic Requirements
Vehicles equipped with EOBD, can be diagnosed
using the WDS. In order for the EOBD system to
be invoked, a number of criteria must be met. After
any repair, which could affect emissions, a trip must
be carried out on the vehicle, to make sure that
engine management system operates correctly.

Clutch Controls
DESCRIPTION
AND OPERATION
Because of this separate chamber, the braking
system remains operational if a leak occurs in the
hydraulic clutch system.
Function
Pressure is created in the master cylinder when
the clutch pedal is operated.
The hydraulic fluid in the master cylinder is put
under pressure and fed through the pressure pipe
to the slave cylinder.
The displaced hydraulic fluid moves the piston in
the slave cylinder and this in turn slides the release
bearing axially.
The release bearing pushes the bearing inner ring
against the tongues of the diaphragm spring.
The spring induced grip between the clutch disc
and the flywheel is broken.
When the clutch pedal is released the diaphragm
spring presses the piston in the slave cylinder back
to its starting position. The spring induced grip
between the clutch disc and the flywheel is created
again.
A spring in the slave cylinder ensures preload on
the release bearing.
The release bearing is always touching the
pressure plate because of this preload. The extra
travel caused by clutch lining wear is compensated
for by the preload.
There is a choke assembly in the slave cylinder
which helps to increase smoothness when pulling
away.
Because of the choke assembly, the pressure drop
of the fluid leaving the slave cylinder and returning
to the reservoir is delayed.
Because of this, the clutch closing time is delayed
when the clutch pedal is released suddenly, and
a soft and comfortable clutch engagement is
achieved.
Choking does not occur during clutch
disengagement.
A CAUTI0N:Vehicles with an automated shift
manual (ASM) transmission have
a slave
cylinder without
a choke assembly. The
slave cylinders must not be exchanged for
one another.
N0TE:The clutch pedal travel cannot be adjusted.
The release bearing is an interference fit in the
slave cylinder and cannot be renewed separately.
