Jacking and Lifting - Jacking
Description and Operation

Safety Precautions Published: 11-May-2011

WARNING: The jack provided with the vehicle is intended to be used in an emergency for changing a deflated tire. To
avoid damage to the vehicle, never use the jack to raise the vehicle for any other purpose. Refer to the Driver Handbook when
using the jack supplied with the vehicle. Failure to follow these instructions may result in personal injury.
The following safety precautions must be observed when raising the vehicle to carry out service operations:
Never rely on a jack alone to support a vehicle. Always use suitable vehicle stands to provide rigid support.
When working beneath a vehicle, whenever possible use a vehicle hoist instead of a jack and vehicle stands.
Make sure that the vehicle is standing on firm, level ground before using a jack.
Do not rely on the parking brake alone; chock the wheels and put the automatic transmission into Park if possible.
Check that any lifting equipment used has adequate capacity for the load being lifted and is in correct working order.

Noise, Vibration and Harshness - Noise, Vibration and Harshness (NVH)
Description and Operation

Noise, vibration and harshness (NVH) is becoming more important as vehicles become more sophisticated and passenger
comfort levels increase. This section is designed to aid in the diagnosis, testing and repair of NVH concerns.

Noise is defined as sounds not associated with the operation of passenger compartment equipment that interface with
customer satisfaction.
Vibration is defined as impulses felt by the customer that are not caused by road surface changes.
Harshness is a ride quality issue where the customer feels that the vehicle response to the road surface is sharply
transmitted to the customer.

Diagnostic Theory

Diagnosis is more than just following a series of interrelated steps in order to find the solution to the specific condition. It is a
way of looking at systems that are not functioning the way they should and finding out why. Also it is knowing how the system
should work and whether it is working correctly.

There are basic rules for diagnosis. If these rules are followed, the cause of the condition is usually found the first time
through the system.

Know the System

Know how the parts go together.
Know how the system operates as well as its limits and what happens when the system goes wrong.
Sometimes this means checking the system against one that is known to be working correctly.

Know the History of the System
A clue in any one of these areas may save time:
How old or new is the system?
What kind of treatment has it had?
Has it been repaired in the past in such a manner that might relate to the present condition?
What is the repair history?

Know the History of the Condition

Did it start suddenly or appear gradually?
Was it related to some other occurrence such as a collision or previous part renewal?
Know how the condition made itself known; it may be an important clue to the cause.

Know the Probability of Certain Conditions Developing

Look for the simple rather than the complex.
For example:
- Electrical conditions usually occur at connections rather than components.
- An engine no-start is more likely to be caused by a loose wire or small adjustment rather than a sheared-off
camshaft.
Know the difference between impossible and improbable. Certain failures in a system can be improbable but still
happen.
New parts are just that, new. It does not mean they are always good functioning parts.

Do Not Cure the Symptom and Leave the Cause

Lowering the pressure in a front tire may correct the condition of a vehicle leaning to one side, but it does not correct the
original condition.

Be Positive the Cause is Found

Double check the findings.
What caused a worn component?
A loose transmission or engine mount could indicate that other mounts are also loose.

Diagnostic Charts

Charts are a simple way of expressing the relationship between basic logic and a physical system of components. They help
discover the cause of a condition in the least time. Diagnostic charts combine many areas of diagnosis into one visual display:
probability of certain things occurring in a system
speed of checking certain components or functions before others
simplicity of carrying out certain tests before others
elimination of checking huge portions of a system by carrying out simple tests
certainty of narrowing down the search to a small portion before carrying out in-depth testing
The fastest way to find a condition is to work with the tools that are available. This means working with proven diagnostic
charts and the correct special equipment for the system.

Diagnosis and Testing

Principle of Operation

For a detailed description of Noise, Vibration and Harshness issues, refer to the Description and Operation section of the
workshop manual.
REFER to: Noise, Vibration and Harshness (NVH) (100-04 Noise, Vibration and Harshness, Description and Operation).
Inspection and Verification

1. Verify the customer's concerns by operating the vehicle to duplicate the condition.

2. Visually inspect the vehicle to determine any obvious cause(s) of the concern(s).

3. If the inspection reveals obvious causes that can be readily identified, repair as necessary.
4. If the concern(s) remains after the inspection, determine the symptom(s) and refer to the Symptom Chart.

How To Use This Diagnostic Procedure Section

Noise, vibration and harshness (NVH) concerns have become more important as vehicles have become more sensitive to
these vibrations. This section is designed as an aid to identifying these situations
The section provides diagnostic procedures based on symptoms. If the condition occurs at high speed, for instance, the
most likely place to start is under High Speed Shake
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 is 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 concerns and will provide
direction to the correct starting point for diagnosis.

Identify the Condition
NVH problems usually occur in a number of areas:
tires
engine accessories
suspension
driveline
air leakage (wind noise)
squeaks and rattles
heating ventilation and air conditioning (HVAC)
electrical (e.g. motor noise)
transmission
engine

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.

Noise Diagnostic Procedure

Non-Axle Noise

The five most important sources of non-axle noise are exhaust, tires, roof racks, trim and mouldings, and transmission.

Therefore, make sure that none of the following conditions are the cause of the noise before proceeding with a driveline tear
down and diagnosis.

Under certain conditions, the pitch of the exhaust may 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, to some
degree, have this characteristic. Also, any non-standard tire with an unusual tread construction may emit a roar or
whine type noise
Trim and mouldings can also cause whistling or a whining noise
Clunk may be a metallic noise heard when the automatic transmission is engaged in reverse or 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

Noise Conditions

Gear noise is typically a howling or whining due to 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 approximately 64 km/h (40 miles/h) 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 tear down will
disclose what has to be corrected
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 the driving conditions.

Vibration Conditions


wear. NOTE: New Constant Velocity (CV) joints should not be installed unless disassembly and inspection revealed unusual

Clicking, popping or grinding noises may be caused by the following:

Cut or damaged CV joint boots resulting in inadequate or contaminated lubricant in the outboard or inboard CV joint
bearing housings
Loose CV joint boot clamps
Another component contacting the rear drive half shaft
Worn, damaged or incorrectly installed wheel bearing, suspension or brake component
Vibration at highway speeds may be caused by the following:
Out-of-balance front or rear wheels
Out-of-round tires
Driveline imbalance
Driveline run-out (alignment)


NOTE: Rear drive half shafts are not balanced and are not likely to contribute to rotational vibration disturbance.
Shudder or vibration during acceleration (including from rest) may be caused by the following:
Driveline alignment
Excessively worn or damaged outboard or inboard CV joint bearing housing
Excessively high CV joint operating angles caused by incorrect ride height. Check ride height, verify correct spring rate
and check items under Inoperative Conditions
Excessively worn driveshaft components

Leakage Conditions

1. Inspect the CV joint boots for evidence of cracks, tears or splits.

2. Inspect the underbody for any indication of grease splatter in the vicinity of the rear drive half shaft, outboard and
inboard CV joint boot locations, which is an indication of CV joint boot or CV joint boot clamp damage.
3. Inspect the inboard CV joint bearing housing seal for leakage.

Inoperative Conditions

If a CV joint or rear drive half shaft pull-out occurs, check the following:

suspension components for correct location, damage or wear
bushings for wear
subframe for damage
bent or worn components
- Stabilizer bar link
- Left-hand rear suspension lower arm and bushing
- Right-hand rear suspension lower arm and bushing
- Rear wheel hub and rear drive half shaft

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 blacktop 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 piece of information, because

and drive half shaft failure, which could cause serious personal injury and extensive vehicle damage. Failure to follow these
instructions may result in personal injury.


CAUTION: The suspension should not be allowed to hang free. When the CV joint is run at a very high angle, extra
vibration as well as damage to the seals and joints can occur.

The rear suspension lower arm should be supported as far outboard as possible. To bring the vehicle to its correct ride height,
the full weight of the vehicle should be supported in the rear by floor jacks. REFER to: (100-02 Jacking and Lifting)

Jacking (Description and Operation), Lifting (Description and Operation).
1. Raise and support the vehicle. REFER to: (100-02 Jacking and Lifting)
Jacking (Description and Operation), Lifting (Description and Operation).
2. Explore the speed range of interest using the Road Test Quick Checks as previously described.

3. Carry out a coast down in neutral. If the vehicle is free of vibration when operating at a steady indicated speed and
behaves very differently in drive and coast, a transmission concern is likely.

Note, however, that a test on the lift may produce different vibrations and noises than a road test because of the effect of the
lift. It is not unusual to find vibrations on the lift that were not found in the road test. If the condition found on the road can
be duplicated on the lift, carrying out experiments on the lift may save a great deal of time.

Exhaust Neutralization Procedure

1. Raise vehicle on lift and slacken all exhaust fixings.

2. With all fixings loose, neutralize the exhaust system.

3. Tighten all fixings to correct torque, starting at the rear-most point working towards the front of the vehicle.

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.
