100-04-6 Noise, Vibration and Harshness 100-04-6
DIAGNOSIS AND TESTING
2. AccelerationIDeceleration: With slow
acceleration and deceleration, a shake is
sometimes noticed in the steering
wheellcolumn,
seats, front floor panel, front door trim panel or
front end sheet metal. It is a low frequency
vibration (around
9-1 5 cycles per second). It
may or may not be increased by applying the
brakes lightly. REFER to
Idle
BoomIShakeNibration in the Driveline Noise
and Vibration Symptom Chart.
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
powertrainldrivetrain 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.
N0TE: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
c !
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.

I I I Steering gear I
1 2 1 Additional cooling loop I
Independent of the equipment level, all vehicles
have conventional power-assisted rack and pinion
steering with an additional cooling loop.
The steering gear is supplied with hydraulic fluid
by a hydraulic pump.
The hydraulic pump is driven by the accessory
drive belt and has a separate reservoir.
Vehicles with petrol engines have a Power Steering
Pressure (PSP) switch in the pressure line, which
opens as the power steering load increases, thus
signalling to the Powertrain Control Module (PCM)
that it should increase the idle speed.

Principles of Operation
The steering wheel rotational movement is
transferred to the steering gear through the steering
column shaft. The steering gear converts this
rotational movement, through the action of the rack
and pinion gear into lateral movement. This
movement in turn is transferred to the wheel
knuckles through the tie-rods and tie-rod ends.
Hydraulic fluid under pressure is supplied to the
steering gear by the power steering pump. As the
steering wheel is rotated, the hydraulic fluid is
allowed to pass through the steering gear valve to
one side of a double acting piston, dependent on
which direction the steering wheel is rotated. The
fluid moves the piston, which forms part of the
steering gear, giving power assistance to the effort
required to rotate the steering wheel.
Vehicles with petrol engines, due to the extra load
on the engine imposed by the power steering
pump, have a power steering pressure (PSP)
switch. The switch, which is normally closed, sends a signal
to the powertrain control module (PCM)
during low speed parking manoeuvres. The PCM
responds by maintaining the engine idle speed.
lnspection and Verification
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical
or electrical damage.

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.
