disconnected, a Radio Code Saver will allow sufficient current to pass to maintain the radio receiver/cassette player/mini disc
player and compact disc player memory, operate the clock and supply the door operated interior lights while isolating the
battery in the event of a short circuit.

Reconnecting the Battery


WARNING: If the battery has been on bench charge the cells may be giving off explosive hydrogen gas. Avoid creating
sparks, and if in doubt cover the vent plugs or covers with a damp cloth.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or
damage to sensitive electrical equipment.

Always reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the
battery terminals are secure.
Restart the clock (where installed) and set it to the correct time.
Enter the radio receiver/cassette player/mini disc player and compact disc player keycodes and preset' frequencies, if known.

Following reconnection of the battery, the engine should be allowed to idle until it has reached normal operating temperature
as the stored idle and drive values contained within the ECM have been lost. Allow the vehicle to idle for a further three
minutes. Drive the vehicle at constant speeds of approximately 48 km/h (30 mph), 64 km/h (40 mph), 80 km/h (50 mph), 96
km/h (60 mph) and 112 km/h (70 mph) for three minutes each. This will allow the ECM to relearn idle and drive values, and
may cause driveability concerns if the procedure is not carried out.

Connecting a Slave Battery Using Jump Leads


WARNING: If the slave battery has recently been charged and is gassing, cover the vent plugs or covers with a damp
cloth to reduce the risk of explosion should arcing occur when connecting the jump leads.
CAUTIONS:


A discharged battery condition may have been caused by an electrical short circuit. If this condition exists there will be
an apparently live circuit on the vehicle even when all circuits are switched off. This can cause arcing when the jump leads are
connected.


Whilst it is not recommended that the vehicle is jump started, it is recognized that this may occasionally be the only
practical way to mobilize a vehicle. In such an instance the discharged battery must be recharged immediately after jump
starting to avoid permanent damage.
Always make sure that the jump leads are adequate for the task. Heavy duty cables must be used.
Always make sure that the slave battery is of the same voltage as the vehicle battery. The batteries must be connected
in parallel.
Always make sure that switchable electric circuits are switched off before connecting jump leads. This reduces the risk
of sparks occurring when the final connection is made.




WARNING: Make sure that the ends of the jump leads do not touch each other or ground against the vehicle body at any
time while the leads are attached to the battery. A fully charged battery, if shorted through jump leads, can discharge at a rate
well above 1000 amps causing violent arcing and very rapid heating of the jump leads and terminals, and can even cause the
battery to explode.
Always connect the jump leads in the following sequence.
Slave battery positive first then vehicle battery positive.
Slave battery negative next and then vehicle ground at least, 300 mm (12 in) from the battery terminal e.g. engine
lifting bracket. www.JagDocs.com

General Information - Standard Workshop Practices
Description and Operation

Protecting the Vehicle Published: 04-Jul-2014

Always install covers to protect the fenders before commencing work in the engine compartment. Always install the interior
protection kit, wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic
fluid, antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water immediately. Use polythene
sheets in the luggage compartment to protect carpets. Always use the recommended service tool, or a satisfactory equivalent,
where specified. Protect temporarily exposed screw threads by replacing nuts or installing caps.

Vehicle in Workshop

When working on a vehicle in the workshop always make sure that:

The parking brake is applied or the wheels are securely chocked to prevent the vehicle moving forwards or backwards
If the engine is to be run, there is adequate ventilation, or an extraction hose to remove exhaust fumes is installed
There is adequate room to jack up the vehicle and remove the wheels, if necessary
Fender covers are always installed if any work is to be carried out in the engine compartment
The battery is disconnected if working on the engine, underneath the vehicle, or if the vehicle is jacked up


CAUTION: When electric arc welding on a vehicle, always disconnect the generator wiring to prevent the possibility of a
surge of current causing damage to the internal components of the generator.
If using welding equipment on the vehicle, ensure a suitable fire extinguisher is readily available.

Screw Threads

Damaged nuts, bolts and screws must always be discarded. Attempting to recut or repair damaged threads with a tap
or die impairs the strength and fit of the threads and is not recommended.
NOTES:

During certain repair operations, it may be necessary to remove traces of thread locking agents using a tap. Where this
is necessary, the instruction to do so will appear in the relevant operation and it is essential that a tap of the correct size and
thread is used.


New Taptite bolts when used cut their own threads on the first application.

Some bolts are coated with a thread locking agent and unless stated otherwise, they must not be reused. New bolts
having the same part number as the original must always be installed. When nuts or bolts are to be discarded, the
repair operation and relevant torque chart will include an instruction to that effect. Do not use proprietary thread
locking agents as they may not meet the specification required. See also Encapsulated ('Patched') Bolts and Screws.
Always make sure that replacement nuts and bolts are at least equal in strength to those that they are replacing.
Castellated nuts must not be loosened to accept a split pin except in recommended cases when this forms part of an
adjustment.
Do not allow oil or grease to enter blind holes, the hydraulic action resulting from tightening the bolt or stud can split
the housing and also give a false torque reading.
Always tighten a nut, bolt or screw to the specified torque figure, damaged or corroded threads can give a false torque
reading.
Nut and bolt loosening and tightening sequences, where given, must ALWAYS be followed. Distortion of components or
faulty sealing of joints will result if the sequences are not followed. Where an instruction is given to tighten in stages,
these stages must be adhered to; do not attempt to combine stages particularly where certain stages involve
tightening by degrees.
To check or re-tighten a fixing to a specified torque, first loosen a quarter of a turn, then retighten to the specified
torque figure.
Unless instructed otherwise, do not lubricate bolt or nut threads prior to installing.
Where it is stated that bolts and screws may be reused, the following procedures must be carried out:
Check that threads are undamaged.
Remove all traces of locking agent from the threads.

CAUTION: DO NOT use a wire brush; take care that threads are not damaged.
Make sure that threads are clean and free from oil or grease.
Apply the specified locking agent to the bolt threads.

WARNINGS:


When handling an inflatable tubular structure (ITS) airbag module, hold by the gas generator housing, DO NOT hold by
the airbag. Do not wrap the thumb around the gas generator while holding. Do not drape airbag over shoulder or around neck.
For seat buckle type pre-tensioners, hold by the piston tube, with the open end of the piston tube pointing towards the ground
and the buckle facing away from your body. Do not cover the end of the piston tube. DO NOT hold buckle type pre-tensioners
by the bracket assembly or cable. Never point the piston tube towards your body or other people.


Airbag modules and seat belt pre-tensioners are classed as explosive devices. For overnight and longer term storage,
they must be stored in a secure steel cabinet which has been approved as suitable for the purpose and has been registered
with the local authority.


Store airbag modules or seat belt pre-tensioners in a designated storage area. If there is no designated storage area
available, store in the locked luggage compartment of the vehicle and inform the workshop supervisor.


CAUTION: Improper handling or storage can internally damage the airbag module making it inoperative. If you suspect
the airbag module has been damaged, install a new module and refer to the deployment/disposal procedures for disposal of
the damaged module.
SRS harness and connectors

Always observe the following precautions with regards to SRS system electrical wiring:



Never attempt to modify, splice or repair SRS wiring.
Never install electrical equipment such as a mobile telephone, two-way radio or in-car entertainment system in such a
way that it could generate electrical interference in the airbag harness. Seek specialist advice when installing such
equipment.


NOTE: SRS wiring can be identified by a special yellow outer sleeve protecting the wires (black with yellow stripe
protective coverings are sometimes used). www.JagDocs.com

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.

Front Airbag Deployment - Driver and Passenger

CAUTION: If the front airbags are deployed, the following components must be replaced:
Driver airbag module
Passenger airbag module
Fly leads (where applicable) connecting front airbag modules to SRS harness
Front seat belt buckle pre-tensioner

General Information - Diagnostic Trouble Code (DTC) Index DTC: Adaptive
Damping Module (SUMB)
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

he table below lists all diagnostic trouble codes (DTCs) that could be logged in the adaptive damping module, for additional
diagnosis and testing information refer to the relevant diagnosis and testing section
