Description and Operation
WARNINGS:

Cured polyurethane (PU) adhesive can degrade if subjected to high temperatures. Isocyanide compounds can be released
when grinding or welding in close proximity to cured PU adhesive.


SKIN CONTACT: Prolonged exposure to polyurethane (PU) adhesive may cause skin irritation. If PU adhesive comes into
contact with the skin, remove any contaminated clothing. Immediately wash the skin with soap and water. Seek medical
attention for any persistent skin irritation or abnormality.


EYE CONTACT: Polyurethane (PU) adhesive may cause severe irritation or damage. If PU adhesive comes into contact with
the eyes, immediately flush eyes with plenty of running water for at least 15 minutes. Seek immediate medical attention.


SWALLOWED: If polyurethane (PU) adhesive is swallowed, flush the mouth thoroughly. Do not induce vomiting. Provide
rest, warmth and fresh air. Seek immediate medical attention.


INHALED: Persons having a respiratory allergy may have an allergic reaction when handling polyurethane (PU) adhesive.


INHALED: Polyurethane (PU) adhesive can cause asthma like symptoms. Isocyanate vapor from primer or PU adhesive can
cause allergies in the respiratory tract.


INHALED: If polyurethane (PU) adhesive fumes are inhaled, move victim to fresh air. Provide oxygen if necessary. If
breathing stops, provide artificial respiration. Keep a victim warm and at rest. Seek immediate medical attention.
CAUTIONS:


Make sure that the direct glazing for bonded glass cutting blades are changed where the cutting depth changes to avoid
damage to the body and trim panels.


During the curing period of the PU adhesive, the door windows must be left open to avoid a build up of pressure when the
doors are opened and closed.

Hum

Continuous sound of varying frequencies, like a wire humming in the wind.

Knock

Heavy, loud repeating sound like a knock on a door.

Ping

Similar to knock, except at higher frequency.

Rattle

A sound suggesting looseness, such as marbles rolling around in a can.

Roar

Deep, long, prolonged sound like an animal, or winds and ocean waves.

Rumble

Low, heavy continuous sound like that made by wagons or thunder.

Scrape

Grating noise like one hard plastic part rubbing against another.

Squeak

High-pitched sound like rubbing a clean window.

Squeal

Continuous, high-pitched sound like running finger nails across a chalkboard.

Tap

Light, hammering sound like tapping pencil on edge of table. May be rhythmic or intermittent.

Whirr/Whine

High-pitched buzzing sound, like an electric motor or drill.

Whistle

Sharp, shrill sound, like wind passing a small opening.

Specific Steering System Noise Types
Belt Squeal
Belt squeal is a high frequency air-borne noise generated by slippage of the ribbed Vee belt on the power steering pump
pulley. Squeal increases with system loading and at full lock.

Clonk

Clonk is a structure-borne noise heard as a loose-sounding rattle or vibration coming from the steering column. Clonk can be
identified by driving and turning over cobblestones, rough roads, or high frequency bumps such as 25-50 mm tall tar strips.
Clonk requires a tie-rod load impact.

Column Knock

Column knock is a loose-sounding rattle or vibration generated by the steering column shaft contacting other portions of the
column assembly. The noise is both audible and tactile. Column knock is generated by driving over cobblestones or rough
pavement. It is not necessary to turn the steering wheel to create this noise.

Column Rattle

Column rattle is a metallic sounding noise created when applying a highly impulsive force to the steering wheel. Column rattle
is often used to combine the more general group of column noises including clonk and column knock. Column rattle noises can
be caused by clonk, knock, loose column components, bonus parts etc. A series of parked, straight-line driving, and cornering
tests should be carried out to isolate the source/sources.

Grinding/Scrape

Grinding is a low frequency noise in the column when the steering wheel is turned. It is generally caused by interference

ECM ADAPTIONS System Operation

The ECM (engine control module) has the ability to adapt the input values it uses to control certain outputs. This capability
maintains engine refinement and ensures the engine emissions remain within the legislated limits. The components which
have adaptions associated with them are:

The APP (accelerator pedal position) sensor
The heated oxygen sensors
The MAFT (mass air flow and temperature) sensors
The CKP (crankshaft position) sensor
Electronic throttle.

OXYGEN AND MAFT SENSORS

There are several adaptive maps associated with the fueling strategy. Within the fueling strategy the ECM calculates short-term adaptions and long term adaptions. The ECM will monitor the deterioration of the heated oxygen sensors over a period of time. It will also monitor the current correction associated with the sensors.

The ECM will store a fault code in circumstances where an adaption is forced to exceed its operating parameters. At the same time, the ECM will record the engine speed, engine load and intake air temperature.
CRANKSHAFT POSITION SENSOR

The characteristics of the signal supplied by the CKP sensor are learned by the ECM. This enables the ECM to set an adaption and support the engine misfire detection function. Due to the small variation between different drive plates and different CKP sensors, the adaption must be reset if either component is renewed, or removed and refitted. It is also necessary to reset the
drive plate adaption if the ECM is renewed or replaced. The ECM supports four drive plate adaptions for the CKP sensor. Each adaption relates to a specific engine speed range. The engine speed ranges are detailed in the table below:

Adaption Engine Speed, rev/min 1 1800 - 3000 2 3001 - 3800 3 3801 - 4600 4 4601 - 5400 MISFIRE DETECTION

Legislation requires that the ECM must be able to detect the presence of an engine misfire. It must be able to detect misfires at two separate levels. The first level is a misfire that could lead to the legislated emissions limit being exceeded by a given
amount. The second level is a misfire that may cause catalytic converter damage.

The ECM monitors the number of misfire occurrences within two engine speed ranges. If the ECM detects more than a predetermined number of misfire occurrences within either of these two ranges, over two consecutive journeys, it will record a
fault code and details of the engine speed, engine load and engine coolant temperature. In addition, the ECM monitors the number of misfire occurrences that happen in a 'window' of 200 engine revolutions. The misfire occurrences are assigned a
weighting according to their likely impact on the catalytic converters. If the number of misfires exceeds a given value, the ECM stores catalytic converter damage fault codes, along with the engine speed, engine load and engine coolant temperature.

The signal from the CKP sensor indicates how fast the poles on the drive plate are passing the sensor tip. A sine wave is generated each time a pole passes the sensor tip. The ECM can detect variations in drive plate speed by monitoring the sine wave signal supplied by the crankshaft position sensor. By assessing this signal, the ECM can detect the presence of an engine misfire. At this time, the ECM will assess the amount of variation in the signal received from the CKP sensor and assign a roughness value to it. This roughness value can be viewed within the real time monitoring feature using Jaguar approved
diagnostic equipment. TheECM will evaluate the signal against a number of factors and will decide whether to record the occurrence or ignore it. The ECM can assign a roughness and misfire signal for each cylinder.
