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 conditions 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 luggage compartment 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 miles/h): With light acceleration, a moaning noise is heard and possibly a vibration is felt in the
front floor pan. 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 Symptom Chart.
2. Acceleration/deceleration: With slow acceleration and deceleration, a shake is sometimes noticed in the steering
wheel/column, seats, front floor pan, 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 brakes lightly. Refer to Idle Boom/Shake
/Vibration in the Symptom Chart.
3. High speed: A vibration is felt in the front floor pan 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 or shift control selector lever in
neutral 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 High Speed Shake in the 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 torque converter which turns at engine speed
when the vehicle is stopped. Refer to High Speed Shake in the Symptom Chart.
5. Noise/vibration while turning: Clicking, popping, or grinding noises may be due to a worn, damaged, or incorrectly
installed front wheel bearing, rear drive half shaft or CV joint.
6. Noise/vibration that is road speed relative: This noise/vibration can be diagnosed independent of engine speed or gear
selected (engine speed varies but torque and road speed remain constant). The cause may be a rear drive
axle/differential whine.
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 the condition has been corrected, make sure all components removed have been installed.
Lift Test
After a road test, it is sometimes useful to do a similar test on a lift.
When carrying out the high-speed shake diagnosis or engine accessory vibration diagnosis on a lift, observe the following
precautions:
WARNING: If only one drive wheel is allowed to rotate, speed must be limited to 55 km/h (35 miles/h) indicated on the
speedometer since actual wheel speed will be twice that indicated on the speedometer. Speed exceeding 55 km/h (35 miles/h)
or allowing the drive wheel to hang unsupported could result in tire disintegration, differential failure, constant velocity joint

Upper Control Arm
The forged-aluminum upper control arm is a wishbone design and connects to the vehicle body through two plain bushes, and
links to the swan neck wheel knuckle by an integral ball joint. The upper control arm is inclined to provide anti-dive
characteristics under heavy braking, while also controlling geometry for vehicle straight-line stability.
Lower Control Arm
The forged aluminum lower control arms are of the wishbone design; the arms separate to allow for optimum bush tuning:
The rear lateral control arm is fitted with a bush at its inner end which locates between brackets on the subframe. The
arm is secured with an eccentric bolt which provides the adjustment of the suspension camber geometry. The outer end
of the control arm has a tapered hole which locates on a ball joint fitted to the wheel knuckle. An integral clevis bracket
on the forward face of the lateral control arm allows for the attachment of the forward control arm. A bush is fitted
below the clevis bracket to provide for the attachment of the stabilizer bar link. A cross-axis joint is fitted to a
cross-hole in the control arm to provide the location for the clevis attachment of the spring and damper assembly.
The forward control arm is fitted with a fluid-block rubber bush at its inner end which locates between brackets on the
subframe. The arm is secured with an eccentric bolt which provides adjustment of the castor and camber geometry. The
outer end of the control arm is fitted with a cross-axis joint and locates in the integral clevis bracket on the lateral
control arm.
Wheel Knuckle
The cast aluminum wheel knuckle is a swan neck design and attaches to the upper control arm and lower lateral control arm.
The lower lateral control arm locates on a non serviceable ball-joint integral with the wheel knuckle. The lower boss on the
rear of the knuckle provides for the attachment of the steering gear tie-rod ball joint.
The wheel knuckle also provides the mounting locations for the:
wheel hub and bearing assembly
the wheel speed sensor (integral to the wheel hub and bearing assembly)
brake caliper and disc shield.
Stabilizer Bar
The stabilizer bar is attached to the front of the subframe with bushes and mounting brackets. The pressed steel mounting
brackets locate over the bushes and are attached to the cross member with bolts screwed into threaded locations in the
subframe. The stabilizer bar has crimped, 'anti-shuffle' collars pressed in position on the inside edges of the bushes. The
collars prevent sideways movement of the stabilizer bar.
The stabilizer bar is manufactured from 32mm diameter tubular steel on supercharged models and 31mm diameter tubular
steel on diesel and normally aspirated models and has been designed to provide particular characteristics in maintaining roll
rates, specifically in primary ride comfort.
Each end of the stabilizer bar curves rearwards to attach to a ball joint on a stabilizer link. Each stabilizer link is secured to a
bush in the lower lateral arm with a bolt and locknut. The links allow the stabilizer bar to move with the wheel travel providing
maximum effectiveness.
The only difference between the front stabilizer bars, in addition to the diameter, is in the shape to accommodate engine
variant:
a slightly curved bar, between bush centers, for V6 diesel (31 mm dia) and V8 gasoline supercharged (32 mm dia),
a straight bar, between bush centers, for V6 and V8 normally aspirated gasoline engines (31 mm dia).
Spring and Damper Assembly
The spring and damper assemblies are located between the lower lateral arm and the front suspension housing in the inner
wing. Dependant on vehicle model there are three types of coil spring and damper available:
a standard oil passive damper (All models except supercharged),
an adaptive damper, also known as Computer Active Technology Suspension (CATS) on 4.2L supercharged vehicles up to
2010MY, For additional information refer to Vehicle Dynamic Suspension 4.2L.
a continuously variable adaptive damper, also known as Adaptive Dynamics System on 5.0L supercharged vehicles from
2010MY. For additional information refer to Vehicle Dynamic Suspension 5.0L.
The dampers are a monotube design with a spring seat secured by a circlip onto the damper tube. The damper's lower
spherical joint is an integral part of the lateral lower control-arm, and the damper takes the form of a clevis-end, which
straddles the spherical joint.
The damper piston is connected to a damper rod which is sealed at its exit point from the damper body. The threaded outer
end of the damper rod locates through a hole in the top mount. A self locking nut secures the top mount to the damper rod.
The damper rod on the adaptive damper has an electrical connector on the outer end of the damper rod.
Supercharged 4.2L vehicles up to 2010MY: The adaptive damper functions by restricting the flow of hydraulic fluid through
internal galleries in the damper's piston. The adaptive damper has a solenoid operated valve, which when switched allows a
greater flow of hydraulic fluid through the damper's piston. This provides a softer damping characteristic from the damper. The
adaptive damper defaults to a firmer setting when not activated. The solenoid is computer controlled and can switch between
soft and hard damping settings depending on road wheel inputs and vehicle speed.
Supercharged 5.0L vehicles from 2010MY: The variable damper functions by adjustment of a solenoid operated variable orifice,
which opens up an alternative path for oil flow within the damper. When de-energized the bypass is closed and all the oil flows

7 Initiators 8 TPMS module 9 Instrument cluster
Tire Pressure Monitoring System (TPMS) System Operation
The controlling software for the Tire Pressure Monitoring System (TPMS) is located within a Tire Pressure Monitoring System
Module. The software detects the following:
When the tire pressure is below the recommended low pressure value - under inflated tire.
The location of the tire on the vehicle that is below the recommended pressure.
Malfunction warning.
The TPMS system comprises:
Tire pressure monitoring system module located below the right-hand front seat.
Tire pressure receiver located near the gear shifter within the floor console.
Two front initiators positioned forward of the wheels and behind the fender splash shields.
Two rear initiators positioned rearward of the wheels and assembled on dedicated brackets located behind the fender
splash shields.
Four sensors, each sensor is integral with a tire valve and located within the tire; the space saver spare wheel is not
fitted with a sensor.
The four initiators are hard wired to the TPMS module. The initiators transmit 125 KHz Low Frequency (LF) signals to the tire
pressure sensors which respond by modifying the mode status within the Radio Frequency (RF) transmission. The 315 or 433
MHz RF signals are detected by the tire pressure receiver which is connected directly to the TPMS module. The received RF
signals from the tire pressure sensors are passed to the TPMS module and contain identification, pressure, temperature and
acceleration information for each wheel and tire.
The TPMS module communicates with the instrument cluster via the medium speed CAN bus to provide the driver with
appropriate warnings. The TPMS module also indicates status or failure of the TPMS or components.
Tire Location and Identification
The TPMS can identify the position of the wheels on the vehicle and assign a received tire pressure sensor identification to a
specific position on the vehicle, for example front left, front right, rear left and rear right. This feature is required because of
the different pressure targets and threshold that could exist between the front and rear tires.
The wheel location is performed automatically by the TPMS module using an 'auto-location' function. This function is fully
automatic and requires no input from the driver. The TPMS module automatically re-learns the position of the wheels on the
vehicle if the tire pressure sensors are replaced or the wheel positions on the vehicle are changed.
The TPMS software can automatically detect, under all operating conditions, the following:
one or more new tire pressure sensors have been fitted
one or more tire pressure sensors have stopped transmitting
TPMS module can reject identifications from tire pressure sensors which do not belong to the vehicle
two 'running' wheels on the vehicle have changed positions.
If a new tire pressure sensor is fitted on any 'running' wheel, the module can learn the new sensor identification automatically
through the tire learn and location process.
The tire-learn and location process is ready to commence when the vehicle has been stationary or traveling at less than 12
mph (20 km/h) for 15 minutes. This is known as 'parking mode'. The learn/locate process requires the vehicle to be driven at
speeds of more than 12 mph (20 km/h) for 15 minutes. If the vehicle speed reduces to below 12 mph (20 km/h), the learn
process timer is suspended until the vehicle speed increases to more than 12 mph (20 km/h), after which time the timer is
resumed. If the vehicle speed remains below 12 mph (20 km/h) for more than 15 minutes, the timer is set to zero and process
starts again.
Low Pressure Monitoring
The tire low pressure sensor transmits by RF (315 MHz or 433 MHz depending on market) signal. These signals contain data
which corresponds to tire low pressure sensor identification, tire pressure, tire temperature, acceleration and tire low pressure
sensor mode.
Each time the vehicle is driven, the tire pressure monitoring system module activates each LF antenna in turn. The
corresponding tire low pressure sensor detects the LF signal and responds by modifying the mode status within the RF
transmission.
The system enters 'parking mode' after the vehicle speed has been less than 20 km/h (12.5 miles/h) for 12 minutes. In parking
mode the tire low pressure sensors transmit a coded signal to the tire pressure monitoring system module once every 13
hours. If the tire pressure decreases by more than 0.06 bar (1 lbf/in²) the tire low pressure sensor will transmit more often as
pressure is lost.
As each wheel responds to the LF signal from the tire pressure monitoring system module, it is assigned a position on the
vehicle and is monitored for the remainder of that drive cycle in that position.

Description and Operation
OVERVIEW
Adaptive Dynamics - Supercharged Vehicles from 2010MY
The adaptive dynamics system, is an electronically controlled suspension system which constantly adjusts the damping
characteristics of the suspension dampers in reaction to the existing driving conditions. The adaptive dynamics system is
available on specified models.
The system is controlled by an Adaptive Damping Module (ADM), located beneath the right-hand front seat. The module
receives signals from three dedicated vertical accelerometers; two at the front of the vehicle and one at the rear, which,
together with four suspension height sensors, determine the state of the body and wheel motions. In addition to these inputs,
further signals from other vehicle electronic system components to determine vehicle state and driver inputs are monitored by
the adaptive damping module. These combined signals are used by the adaptive damping module to continuously adjust the
damping characteristics of each of the suspension dampers in reaction to the current driving conditions to give the optimum
body control and vehicle ride.
