Standard Workshop Practices
Vehicle in Workshop
When working on a vehicle in the workshop always
make sure that:
– the parking brake is applied or the wheels aresecurely chocked to prevent the vehicle moving
forwards or backwards.
– the key is removed from key operated hood locks before any work is carried out around the
front of the vehicle.
– if the engine is to be run, there is adequate ventilation, or an extraction hose to remove
exhaust fumes.
– there is adequate room to raise the vehicle and remove the wheels, if necessary.
– fender covers are always fitted if any work is to be carried out in the engine compartment.
– the battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle
is raised.
CAUTION: When electric arc welding on a
vehicle, always disconnect the generator
wiring to prevent the possibility of a surge
of current causing damage to the internal
components of the generator.
– if using welding equipment on the vehicle, a suitable fire extinguisher is readily available.
Towing the Vehicle
WARNING: When the vehicle is being
towed, the ignition switch must be in
position II (steering lock released and
warning lamps illuminated). Only then will
the steering, turn signal lamps, horn and
stop lamps be operational. Failure to follow
these instructions may result in personal
injury.
NOTE: The removable towing eye (if equipped),
has a left-hand thread and must be fully tightened
before towing can commence.
When towing is necessary, the vehicle towing eyes
should be used. The rope must be securely
fastened to the towing eyes and must also be
attached to the other vehicle such that the rope will
not foul the bodywork.
When a vehicle with automatic transmission is
towed, the gear selector must be in position N (Neutral). Never tow a vehicle with automatic
transmission at a speed greater than 30 mph (50
km/h) or for a distance greater than 30 miles (50
km). If it is necessary to tow the vehicle a greater
distance, the drive wheels must be lifted clear off
the ground.
Alternatively the vehicle can be transported on a
low loader or a trailer.
Connecting a Slave Battery Using
Jumper Cables
WARNING: If the slave battery has recently
been charged and is gassing, cover the
vent plugs or covers with a damp cloth to
reduce the risk of explosion should arcing
occur when connecting the jumper cables.
Failure to follow these instructions may
result in personal injury.
CAUTIONS:
A discharged battery condition may have
been caused by an electrical short circuit.
If this condition exists there will be an
apparently live circuit on the vehicle even
when all normal circuits are switched off.
This can cause arcing when the jumper
cables are connected.
While it is not recommended that the
vehicle is jump started, it is recognized
that this may occasionally be the only
practical way to mobilize a vehicle. In such
an instance, the discharged battery must
be recharged immediately after jump
starting to avoid permanent damage.
– Always make sure that the jumper cables are adequate for the task. Heavy duty cables must
be used.
– Always make sure that the slave battery is of the same voltage as the vehicle battery. The
batteries must be connected in parallel.
– Always make sure that switched electric circuits are switched off before connecting jumper
cables. This reduces the risk of arcing occurring
when the final connection is made.

WARNING: Make sure that the ends of the
jumper cables do not touch each other or
ground against the vehicle body at any
time while the cables are attached to the
battery. A fully charged battery, if shorted
through jumper cables, can discharge at
a rate well above 1000 amps causing
violent arcing and very rapid heating of the
jumper cables and terminals, and can even
cause the battery to explode. Failure to
follow these instructions may result in
personal injury.
Always connect the jumper cables in the following
sequence:
– Slave battery positive first and then vehicle battery positive.
– Slave battery negative next and then vehicle ground at least 12 inches (300 mm) from the
battery terminal, for example engine lifting eye.
Always reduce the engine speed to idle before
disconnecting the jumper cables.
Before removing the jumper cables from the vehicle
that had the discharged battery, switch on the
heater blower (high) or the heated rear window, to
reduce the voltage peak when the cables are
removed.
Always disconnect the jumper cables in the reverse
order to the connecting sequence and do not short
the ends of the cables.
Do not rely on the generator to restore a
discharged battery. For a generator to recharge a
battery, it would take in excess of eight hours
continuous driving with no additional loads placed
on the battery.
Component Cleaning
To prevent the ingress of dirt, accumulations of
loose dirt and greasy deposits should be removed before disconnecting or dismantling components
or assemblies.
Components should be thoroughly cleaned before
inspection prior to reassembly.
Cleaning Methods:
– Dry cleaning.
– Removal of loose dirt with soft or cable brushes.
– Scraping dirt off with a piece of metal or wood.
– Wiping off with a rag.
WARNING: Wear eye protection when
cleaning vehicle components with
compressed air, a steam cleaner or a
power washer. Failure to follow this
instruction may result in personal injury.
CAUTIONS:
Compressed air is sometimes 'wet' so use
with caution, especially on hydraulic
systems.
To prevent damage to the electrical
connectors in the engine compartment, do
not use a steam cleaner or a power washer
to clean the engine compartment.
– Blowing dirt off with compressed air.
– Removal of dry dust using vacuum equipment. This method must always be used to remove
friction lining material dust (asbestos particles).
– Steam cleaning.
WARNING: Most solvents require careful
handling and some are harmful. Refer to
Health and Safety Precautions and to the
manufacturers literature for the relevant
safety precautions. Failure to follow these
instructions may result in personal injury.
Various solvents are available which are suitable
for component cleaning. Some components, such
as brake hydraulic parts and electrical assemblies
should be cleaned only with recommended solvents
— refer to Solvents, Sealers and Adhesives or to
the section of the manual relevant to the
component.
Calibration of Essential Measuring
Equipment
WARNING: Equipment, which requires
regular calibration, must be calibrated in
accordance with the manufacturers

Road/Roller Testing
Road or roller testing may be carried out for various
reasons and a procedure detailing pre-test checks,
engine starting and stopping, pre-driving checks,
on-test checks and final checks to be completed
on completion of the test is given below.
Unless complete vehicle performance is being
checked, the full road test procedure need not be
carried out. Instead, those items particularly
relevant to the system(s) being checked can be
extracted.
Pre-Test Checks
WARNING: If the brake system hydraulic
fluid level is low, pedal travel is excessive
or a hydraulic leak is found, do not attempt
to road test the vehicle until the reason for
the low fluid level, excessive pedal travel
or hydraulic leak is found and rectified.
It is suggested that pre-test checks and functional
tests of those systems and circuits which affect the
safe and legal operations of the vehicle, such as
brakes, lights and steering, should always be
carried out before the road or roller test.
With the ignition switched off, check:
– the engine oil level.
– the engine coolant level.
– the tires, for correct pressure, compatible types and tread patterns, and wear within limits.
– that there is sufficient fuel in the tank to complete the test.
– all around the engine, transmission and under the vehicle for oil, coolant, hydraulic and fuel
leaks. Make a note of any apparent leaks and
wipe off the surrounding areas to make it easier
to identify the extent of the leak on completion
of the test.
Starting the Engine
NOTE: On initial drive away from cold and within
the first 1.5 km (1 mile), do not depress the
accelerator pedal beyond half travel until the
vehicle has attained a minimum speed of 25 km/h
(15 miles/h). Never operate at high engine speed
or with the accelerator pedal at full travel whilst the
engine is cold.
With the ignition switched off, check: – that the parking brake is applied.
– that the gear lever is in the neutral position.
– that all instrument gauges (except fuel gauge)
read zero.
With the ignition switched on, check:
– that the ignition controlled warning lamps are illuminated.
– that the engine temperature gauge registers a reading compatible with the engine temperature.
– that the fuel gauge registers a reading appropriate to the fuel level in the tank.
– the operation of the parking brake warning lamp and fluid level warning indicator.
Road or Roller Testing
CAUTION: If road testing, check the brake
operation while still traveling at low speed
before continuing with the test. If the
brakes pull to one side, or appear to be
otherwise faulty, do not continue with the
road test until the fault has been found and
rectified.
During the road or roller test, check:
– that the clutch pedal operation is not stiff or heavy.
– that the initial gear engagement is smooth and there is no evidence of clutch drag.
– that the parking brake control operates smoothly and releases quickly and completely.
– that the clutch takes up the drive smoothly, without slip or judder.
– that gear changing is smooth with no abnormal noises or vibrations from the transmission.
– the engine power output is satisfactory, full power is achieved, acceleration is smooth and
pedal operation is not stiff or heavy, and engine
speed returns to idle correctly.
– there is no excessive or abnormally colored smoke from the engine under normal driving,
heavy load or overrun conditions.
– that steering operation, including power steering (if equipped), is smooth, accurate, not
excessively heavy or with excessive free play
or vibration.
– that the steering does not pull to one side and self centers smoothly after cornering.

Noise Conditions
• Gear noise is typically a howling or whining dueto gear damage or incorrect bearing preload. It
can occur at various speeds and driving
conditions, or it can be continuous.
• Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning
bicycle wheel. It occurs while decelerating from
64 km/h (40 mph) and can usually be heard all
the way to a stop. The frequency varies with
vehicle speed.
• Knock is very similar to chuckle, though it may be louder and occurs on acceleration or
deceleration. The teardown will disclose what
has to be corrected.
Clicking, popping or grinding noises may be caused
by the following:
• worn, damaged or incorrectly installed wheel bearing, suspension or brake component.
Check and rule out tires, exhaust and trim items
before disassembling the transmission to diagnose
and correct gear noise.
The noises described under Road Test usually
have specific causes that can be diagnosed by
observation as the unit is disassembled. The initial
clues are the type of noise heard on the road test
and driving conditions.
Vibration Conditions
Vibration at highway speeds may be caused by
the following:
• out-of-balance front or rear wheels.
• out-of-round tires.
Shudder or vibration during acceleration may be
caused by the following:
• damaged powertrain/drivetrain mounts.
• excessively high constant velocity (CV) joint operating angles caused by incorrect ride height.
Check ride height, verify correct spring rate and
check items under inoperative conditions.
Road Test
A gear-driven unit will produce a certain amount
of noise. Some noise is acceptable and may be
audible at certain speeds or under various driving
conditions, as on a newly paved asphalt road. The slight noise is in no way detrimental and must be
considered normal.
The road test and customer interview (if available)
provide information needed to identify the condition
and give direction to the correct starting point for
diagnosis.
1. Make notes throughout the diagnosis routine.
Make sure to write down even the smallest bit
of information, because it may turn out to be the
most important.
2. Do not touch anything until a road test and a thorough visual inspection of the vehicle have
been carried out. Leave the tire pressures and
vehicle load just where they were when the
condition was first observed. Adjusting tire
pressures, vehicle load or making other
adjustments may reduce the condition(s)
intensity to a point where it cannot be identified
clearly. It may also inject something new into
the system, preventing correct diagnosis.
3. Make a visual inspection as part of the preliminary diagnosis routine, writing down
anything that does not look right. Note tire
pressures, but do not adjust them yet. Note
leaking fluids, loose nuts and bolts, or bright
spots where components may be rubbing
against each other. Check the load space for
unusual loads.
4. Road test the vehicle and define the condition by reproducing it several times during the road
test.
5. Carry out the Road Test Quick Checks as soon as the condition is reproduced. This will identify
the correct diagnostic procedure. Carry out the
Road Test Quick Checks more than once to
verify they are providing a valid result.
Remember, the Road Test Quick Checks may
not tell where the concern is, but they will tell
where it is not.
Road Test Quick Checks
1. 24-80 km/h (15-50 mph): with light acceleration,a moaning noise is heard and possibly a
vibration felt in the front floor panel. It is usually
worse at a particular engine speed and at a
particular throttle setting during acceleration at
that speed. It may also produce a moaning
sound, depending on what component is
causing it. REFER to Tip-in Moan in the
Driveline Noise and Vibration Symptom Chart.
2. Acceleration/Deceleration: With slow acceleration and deceleration, a shake is

Noise, Vibration and Harshness (NVH)
Inspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanicalor electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible)
before proceeding to the next step.
4. If the concern is not visually evident, verify the symptom and REFER to the Symptom Chart.
How to Use this Diagnostic Procedure
Section
• Noise, vibration and harshness (NVH) concernshave become more important as vehicles have
become more sensitive to these vibrations. This
section is designed to aid in identifying these
concerns.
• The section provides diagnostic procedures based on symptom. If the condition occurs at
high speed, for instance, the most likely place
to start is under Shake and Vibration While
Driving.
• The road test procedure will tell how to sort the conditions into categories and how to tell a
vibration from a shake.
• A series of Road Test Quick Checks are provided to make sure that a cause is either
pinpointed or eliminated.
• Name the condition, proceed to the appropriate section and locate the correct diagnosis. When
the condition is identified, the job is partly done.
• Follow the diagnostic procedure as outlined.
• Quick Checks are described within the step, while more involved tests and adjustments are
outlined in General Procedures.
• Always follow each step exactly and make notes to recall important findings later.
Customer Interview
The road test and customer interview (if available)
provide information that will help identify the
concern and will provide direction to the correct
starting point for diagnosis.
Identify the Condition
NVH usually occur in four areas:
• tires
• engine accessories
• suspension
• driveline
It is important, therefore, that an NVH concern be
isolated into its specific area(s) as soon as
possible. The easiest and quickest way to do this
is to carry out the Road Test as outlined. To assist
in the diagnosis and testing procedure(s), use a
suitable approved NVH diagnosis tester.
Noise Diagnostic Procedure
Non-Axle Noise
The five most common sources of non-axle noise
are exhaust, tires, roof racks, trim panels and
transmission.
Therefore, make sure that none of the following
conditions are the cause of the noise before
proceeding with a driveline teardown and
diagnosis.
• In certain conditions, the pitch of the exhaustmay sound very much like gear noise. At other
times, it can be mistaken for a wheel bearing
rumble.
• Tires, especially snow tires, can have a high pitched tread whine or roar, similar to gear
noise. Radial tires may have this characteristic.
Also, any non-standard tire with an unusual
tread construction may emit a roar or whine
noise.
• Trim panels can also cause whistling or whining noise.
• Clunk may be a metallic noise heard when the automatic transaxle is engaged in "R"
(REVERSE) or "D" (DRIVE) or it may occur
when the throttle is applied or released. It is
caused by backlash somewhere in the driveline.
• Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a
damaged wheel bearing.

sometimes noticed in the steering wheel/column,
seats, front floor panel, front door trim panel or
front end sheet metal. It is a low frequency
vibration (around 9-15 cycles per second). It
may or may not be increased by applying the
brakes lightly. REFER to Idle
Boom/Shake/Vibration in the Driveline Noise
and Vibration Symptom Chart.
3. High Speed: A vibration is felt in the front floor panel or seats with no visible shake, but with
an accompanying sound or rumble, buzz, hum,
drone or booming noise. Coast with the clutch
pedal depressed (manual transmission) or shift
control selector lever in "N" (NEUTRAL)
(automatic transmission) and engine idling. If
vibration is still evident, it may be related to
wheels, tires, front brake discs, wheel hubs or
front wheel bearings. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
4. Engine rpm Sensitive: A vibration is felt whenever the engine reaches a particular rpm.
It will disappear in neutral coasts. The vibration
can be duplicated by operating the engine at
the problem rpm while the vehicle is stationary.
It can be caused by any component, from the
accessory drive belt to the clutch or torque
converter which turns at engine speed when the
vehicle is stopped. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
5. Noise and Vibration While Turning: Clicking, popping or grinding noises may be due to the
following:
• worn, damaged or incorrectly installed front wheel bearing.
• damaged powertrain/drivetrain mounts.
Road Conditions
An experienced technician will always establish a
route that will be used for all NVH diagnosis road
tests. The road selected should be reasonably
smooth, level and free of undulations (unless a
particular condition needs to be identified). A
smooth asphalt road that allows driving over a
range of speeds is best. Gravel or bumpy roads
are unsuitable because of the additional road noise
produced. Once the route is established and consistently used, the road noise variable is
eliminated from the test results.
NOTE:
Some concerns may be apparent only on
smooth asphalt roads.
If a customer complains of a noise or vibration on
a particular road and only on a particular road, the
source of the concern may be the road surface. If
possible, try to test the vehicle on the same type
of road.
Vehicle Preparation
Carry out a thorough visual inspection of the
vehicle before carrying out the road test. Note
anything which is unusual. Do not repair or adjust
any condition until the road test is carried out,
unless the vehicle is inoperative or the condition
could pose a hazard to the technician. After
verifying that the condition has been corrected,
make sure all components removed have been
installed.
Power Steering Conditions
Check for the noise in the following conditions to
verify the customer concern.
• Check for the noise in several temperature conditions.
• Is the noise from when the vehicle was new?
• Can the noise be repeated constantly or is it random?
• Check the condition of the vehicle age, mileage and service record.
• Interview the customer to find the operating condition in which the noise will occur. Test the
vehicle based on the detail(s) from the customer
interview.
• Follow the power steering operation noise condition tables below, to find which condition
the noise will occur.
Power Steering Operation Noise Check
Step 1: Check for NVH concerns from non-steering
components, which may sound like noises coming
from the steering system.
