DESCRIPTION AND OPERATION
Gross or prolonged skin contact with high boiling
point gas oils may also cause serious skin
disorders including skin cancer.
Kerosene (Paraffin)
Used also as heating fuel, solvent and cleaning
agent.
Flammable
- observe No Smoking policy.
Irritation of the mouth and throat may result from
swallowing. The main hazard from swallowing
arises if liquid aspiration into the lungs occurs.
Liquid contact dries the skin and can cause
irritation or dermatitis. Splashes in the eye may be
slightly irritating.
In normal circumstances the low volatility does not
give rise to harmful vapors. Exposure to mists and
vapors from kerosene at elevated temperature
should be avoided (mists may arise in dewaxing).
Avoid skin and eye contact and make sure there
is adequate ventilation.
Alternative Fuel
Highly flammable. Observe "NO SMOKING" signs.
Make sure there is adequate ventilation when
working on alternative fuelled vehicles. Great care
must be taken to avoid the serious consequences
of inhalation in the event of vapor build up in
confined spaces.
Inhalation in high concentrations may cause
dizziness, headache, nausea and loss of
co-ordination. Very high concentrations may result
in loss of consciousness.
Contact with liquefied petroleum gas (LPG) or
compressed natural gas (CNG) to the skin may
cause cold burns and frost bite.
Long sleeved cotton overalls, steel toe capped
safety boots and rubber neoprene gloves should
be worn during removal and installation of
LPGICNG fuel system components.
LPGICNG fuel leaks could cause a fire and be a
hazard to health that can lead to personal injury,
illness or even death.
If a leak is detected, under no circumstances
attempt to seal the leak by tightening the
unionlconnection until the fuel in the system or
component is depressurized. Once tightened the
system should be checked for integrity following
the specified procedures. If
the fuel tank is to be removed for service or repair
the fuel must be evacuated using dedicated
equipment and following the specified
procedures. (
Gas Cylinders
See also Fire.
Gases such as oxygen, acetylene, argon and
propane are normally stored in cylinders at
pressures of up to
138 bar (2000 psi) and great
care should be taken in handling these cylinders
to avoid mechanical damage to them or to the valve
gear attached. The contents of each cylinder
should be clearly identified by appropriate
markings.
Cylinders should be stored in well-ventilated
enclosures, and protected from ice and snow, or
direct sunlight. Fuel gases, for example acetylene
and propane, should not be stored in close
proximity to oxygen cylinders.
Care should be exercised to prevent leaks from
gas cylinders and lines, and to avoid sources of
ignition.
Only trained personnel should undertake work
involving gas cylinders.
Gases

Gaskets (Fluoroelastomer)
See Viton.
General Workshop Tools and
Equipment
It is essential that all tools and equipment are
maintained in good condition and that the correct
safety equipment is used where required.
Never use tools or equipment for any purpose other
than that for which they were designed. Never
overload equipment such as hoists, jacks, axle and
chassis stands or
lifting slings. Damage caused by
overloading is not always immediately apparent
and may result in a fatal failure the next time that
the equipment is used.

Engine - Oil Leaks
NOTE: Before installing new gaskets or seals, make
sure that the fault is clearly established.
If the oil leak cannot be identified clearly by a visual
inspection, carry out an ultraviolet
(UV) test:
Ultraviolet (UV) Testing
1. Clean the engine and transmission with a
suitable cleaning fluid.
2. Pour the UV-test fluid in accordance with the
quantity specified by the manufacturer through
the oil filler neck into the engine and install the
oil filler cap.
A WARN1NG:Vehicles with manual transaxle,
shift the transaxle into Neutral. Failure to
follow this instruction may result in
personal injury.
3. Start the engine and let it run for about five
minutes. 4.
Switch off the engine.
N0TE:lf no leak can be found, road test the vehicle
under various loads and check the engine for leaks
again.
5. Check the engine for oil leaks using a suitable
UV lamp.
'
6. Rectify any leaks found and check the engine
for oil leaks.
Measure the compression pressure
N0TE:The powertrain control module (PCM)
receives an error message when the fuel pump
relay is removed or electrical components are
disconnected. This error message must be deleted
from the fault memory using WDS after completing
the compression test.
(' ,
'I N0TE:Valve clearance must be set correctly before
performing a compression test. Make sure the
engine is at the normal operating temperature.

Principles of Operation
Ethanol equipped vehicles
Ethanol, is derived from cellulose waste. A large
proportion of Ethanol is distilled from corn, wheat
and sugar cane crops. The product that is to be
used in this vehicle is called Ethanol E85. E85 is
a mixture of 15% gasoline and 85% Ethanol.
Ethanol is a clear liquid and when fully burnt the
combustion gasses remaining are Carbon Dioxide
and water. This makes the use of Ethanol a good
environmental proposition. One drawback with pure
Ethanol is that it is corrosive to certain rubber and
plastic materials. The
introduction of Ethanol E85 has required some
major internal changes to the fuel supply and
delivery system. Some earlier vehicles used an
Ethanol mixture called Ethanol
El 5. This fuel was
made up of 15% Ethanol and 85% gasoline. At this
mixture ratio, no changes to the fuel charging or
delivery system where required, as no degradation
would occur with the cylinder head valves or
material content of the components, although some
performance loss would be noticeable.
The components used by vehicles running Ethanol
appear to be the same in construction as those
that use unleaded fuel only. The changes are
mainly to do with the materials used and increases
in fuel flow rates.
Ethanol has a much higher octane rating than
standard fuel which means that the ignition and
fuel injection calibrations for a vehicle that is
capable of using Ethanol E85 must be adapted
suitably.

Electronic Engine Controls
DIAGNOSIS AND TESTING
detected in either the STFT or LTFT, and it is still
present on a second trip, the MIL will be switched

Heated Oxygen Sensor (H02S) Monitor (All except
vehicles with diesel engine)
This monitors the operation of the pre (upstream)
and post (downstream) catalytic converter
H02S
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.
