Repairs and Replacements Published: 28-Dec-2012

When service parts are required, it is essential that only genuine Jaguar/Daimler replacements are used.

Attention is drawn to the following points concerning repairs and the installation of replacement parts and accessories:

Safety features embodied in the vehicle may be impaired if other than genuine parts are installed. In certain territories,
legislation prohibits the installation of parts which are not produced to the vehicle manufacturer's specification.
Torque wrench setting figures given in this manual must be strictly adhered to. Locking devices, where specified, must
be installed. If the efficiency of a locking device is impaired during removal it must be renewed.
Owners purchasing accessories while travelling abroad should make sure that the accessory and its installed location on
the vehicle conform to mandatory requirements existing in their country of origin.
The vehicle warranty may be invalidated by the installation of other than genuine Jaguar/Daimler parts. All
Jaguar/Daimler replacements have the full backing of the factory warranty.
Jaguar/Daimler dealers are obliged to supply only genuine service parts.

Vehicle Specifications

Purchasers are advised that the specification details set out in this manual apply to a range of vehicles and not to any specific
one. For the specification of a particular vehicle, purchasers should consult their dealer.

The Manufacturer reserves the right to vary the specifications, with or without notice, and at such times and in such manner as
the Manufacturer thinks fit. Major as well as minor changes may be involved, in accordance with the Manufacturer's policy of
continuous improvement.

Whilst every effort is made to make sure the accuracy of the particulars contained in this manual, neither the Manufacturer nor
the Dealer, by whom the manual is supplied, shall in any circumstances be held liable for any inaccuracy or the consequences
thereof.

Service Repair Operation Numbering

A master index of numbered operations has been compiled for universal application to all vehicles manufactured by Jaguar
Land Rover Limited.

Each operation is allocated a number from the master index and cross-refers with an identical number in the Repair Operation
Times schedule. The number consists of six digits arranged in three pairs.

Each maintenance procedure in this manual is described in the sequence necessary to complete the operation in the minimum
time, as specified in the Repair Operation Times schedule.

References to Bank-1 and Bank-2

References to Bank-1 and Bank-2 are made with regard to the engine. When viewed from the flywheel the right-hand bank will
be Bank-1 and the left-hand bank will be Bank-2.

Special Tools

Any special tools and equipment required to perform a maintenance procedure, are shown at the beginning of each procedure.
When possible, illustrations are given to assist in identifying the tool needed.

Disconnecting/Connecting the Battery

Always stop the engine before disconnecting the battery negative lead and make sure the battery positive lead is isolated i.e.
wrapped in a suitable cloth.


WARNING: Radio code saving devices must not be used when conducting work on Air Bag or Fuel systems. It must be
noted that, when using these devices, the vehicle electrical system is still live albeit with a reduced current flow.


NOTE: Before disconnecting the battery make sure that the radio receiver/cassette player/mini disc player and compact
disc player keycodes are known and, that no data is required from the Engine Control Module (ECM) as battery disconnection
will erase any fault codes and idle/drive values held in the Keep Alive Memory (KAM).
Always disconnect the battery before commencing repair operations which require:
The vehicle to be jacked up
Work on the engine
Work underneath the vehicle
Arc welding
Alternatively a Radio Code Saver may be used, when not working on the Air Bag or Fuel systems. With the battery

Always reduce the engine speed to idle before disconnecting the jump leads.

Before removing the jump leads, switch on the heater blower (high) or the heated rear screen, to reduce the voltage peak
when the leads are removed.

Always disconnect the jump leads in the reverse order to the connecting sequence and take great care not to short the ends of
the leads.

Do not rely on the generator to restore a discharged battery. For a generator to recharge a battery, it would take in excess of 8
hours continuous driving with no additional loads placed on the battery.

Component Cleaning

To prevent 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 wire brushes
Scraping dirt off with a piece of metal or wood
Wiping off with a rag

CAUTION: Compressed air is sometimes wet so use with caution, especially on hydraulic systems.
Blowing dirt off with compressed air (Eye protection should be worn when using this method)
Removal of dry dust using vacuum equipment. This method should always be used to remove friction lining material
dust (asbestos particles)
Steam Cleaning

Calibration of Essential Measuring Equipment


WARNING: Failure to comply may result in personal injury or damage to components.

It is of fundamental importance that certain essential equipment e.g. torque wrenches, multimeters, exhaust gas analysers,
rolling roads etc., are regularly calibrated in accordance with the manufacturers instructions.

Use of Control Modules

Control modules may only be used on the vehicle to which they were originally installed. Do not attempt to use or test a
control module on any other vehicle.

Functional Test

On completion of a maintenance procedure, a thorough test should be carried out, to ensure the relevant vehicle systems are
working correctly.

Preparation

Before disassembly, clean the surrounding area as thoroughly as possible. When components have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oil ways, exposed
by component removal, with tapered hardwood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a separate container for each component and its associated parts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the materials
within the component. Clean the bench and obtain marking materials, labels, containers and locking wire before dismantling a
component.

Dismantling

Observe scrupulous cleanliness when dismantling components, particularly when parts of the brake, fuel or hydraulic systems
are being worked on. A particle of dirt or a fragment of cloth could cause a dangerous malfunction if trapped in these systems.
Clean all tapped holes, crevices, oil ways and fluid passages with compressed air.


WARNING: Do not permit compressed air to enter an open wound. Always use eye protection when using compressed air.

Make sure that any O-rings used for sealing are correctly reinstalled or renewed if disturbed. Mark mating parts to make sure
that they are replaced as dismantled. Whenever possible use marking materials which avoid the possibilities of causing
distortion or the initiation of cracks, which could occur if a center punch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed for reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not discard a part which is due for renewal until it has been compared with the new part, to make sure

be replaced as soon as possible to make sure full SRS protection.


If the SRS components are to be replaced, the part number/bar code of the new unit must be recorded.

SRS component testing precautions

The SRS components are triggered using relatively low operating currents, always adhere to the following :


WARNING: Never use a multimeter or other general purpose equipment on SRS components. Use only approved JLR
diagnostic equipment to diagnose system faults.




WARNING: Do not use electrical test equipment on the SRS harness while it is connected to any of the SRS components,
it may cause accidental deployment and injury.
Handling and storage

Always observe the following precautions when handling SRS components:



Never drop an SRS component. The airbag diagnostic control unit is a particularly shock sensitive device and must be
handled with extreme care. Airbag modules and seat belt pre-tensioners could deploy if subjected to a strong shock.
Never wrap your arms around an airbag module. If a module has to be carried, hold it by the cover with the cover
uppermost and the base away from your body.
Never transport airbag modules or seat belt pre-tensioners in the passenger compartment of a vehicle. Always use the
luggage compartment of the vehicle for carrying airbag modules and seat belt pre-tensioner units.
Never attach anything to an airbag cover or any trim component covering an airbag module. Do not allow anything to
rest on top of an airbag module.
Always keep components cool, dry and free from contamination.
Never apply grease or cleaning solvents to seat belt pre-tensioner units, component failure could result.
Always store an airbag module with the deployment side uppermost. If it is stored deployment side down, accidental
deployment will propel the airbag module with sufficient force to cause serious injury.
Keep new airbag modules in their original packaging until just prior to installing. Place the old module in the empty
packaging for carriage.

Deployment procedures and precautions as detailed in this manual should be strictly adhered to. Only personnel who have
undergone the appropriate training should undertake deployment of airbag and pre-tensioner modules. The following
precautions must be complied with:
Only use deployment equipment approved for the intended purpose.
Deployment of airbag / pre-tensioner modules must be performed in a well ventilated area which has been designated
for the purpose.
Make sure airbag / pre-tensioner modules are not damaged or ruptured before attempting to deploy.
Where local legislation exists, notify the relevant authorities of intention to deploy airbag and pretensioner units.
When deploying airbag pre-tensioner units, make sure that all personnel are at least 15 metres (45 feet) away from the
deployment zone.
Make sure deployment tool is connected correctly, in compliance with the instructions detailed in the SRS section of this
manual. In particular, make sure deployment tool is NOT connected to battery supply before connecting to airbag
module connector.
When deploying seat belt pre-tensioners, make sure pre-tensioner unit is secured correctly to the seat.
When removing deployed airbag modules and pre-tensioner units, wear protective clothing. Use gloves and seal
deployed units in a plastic bag.
Following deployment of any component of the SRS system within the vehicle, all SRS components must be replaced.
DO NOT reuse or salvage any parts of the SRS system.
Do not lean over an airbag module when connecting deployment equipment.

If a vehicle is to be scrapped, undeployed airbag modules and pre-tensioner units must be manually deployed. In this case
airbags can be deployed in the vehicle. Before deployment, make sure the airbag module is secure within its correct mounting
position. Deployment of the driver's airbag in the vehicle may damage the steering wheel; if the vehicle is not being scrapped,
deploy the module outside of the vehicle.

SRS Component Replacement Policy

CAUTIONS:


The Restraints Control Module (RCM) will log a crash fault after every impact which is severe enough to cause airbag
deployment. It is possible to have three crashes/impacts logged after one event where, for example, a front, side and
rollover has occurred. After the third fault is logged, the SRS warning lamp will be illuminated and the RCM must be
installed. After any airbag deployment a new RCM must be installed.


The SRS side impact sensor must be replaced if there are any signs of physical damage or if the restraints control module
(RCM) is registering a fault.
The following information details the policy for replacement of SRS components as a result of a vehicle accident.

Impacts which do not deploy the airbags or pre-tensioners

Check for structural damage in the area of the impact paying particular attention to bumper armatures, longitudinals and
bracketry.
Impacts which deploy the airbags or pre-tensioners

The replacement and inspection policy is dependent on the type and severity of the crash condition. The following guidelines
are the minimum that should be exercised as a result of the deployment of specific SRS components.

Check for structural damage in the area of impact paying particular attention to bumper armatures, longitudinals and
bracketry.

Description and Operation

Adaptive Damping Module (SUMB)


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle
NOTES:


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
warranty policy and procedures manual, or determine if any prior approval programme is in operation, prior to the installation
of a new module/component


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system)


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places and with a
current calibration certificate. When testing resistance, always take the resistance of the digital multimeter leads into account


Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion


If diagnostic trouble codes are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent
concern may be the cause. Always check for loose connections and corroded terminals


Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the
manufacturers approved diagnostic system


Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
