Introduction
I-I-VI Workshop Manual Issue 7, September 2011
Introduction
Welcome
This Workshop Manual is part of a suite of technical manuals
provided for DB9. Other technical manuals include:
• Parts manual
• OBDII Diagnostic manual
• Man hour schedules
Chapters
The DB9 suite of manuals incorporate a new chapter
structure.
Each chapter in this workshop manual is associated with a 4
digit number, i.e. Transmission (07.00). Each chapter is then
further broken into sections, i.e. Automatic Transmission
(07.01).
Chapter Navigation
Example 1:
Previous workshop manuals would have Steering and
Suspension together in one chapter. The new structure now
places Steering and Suspension into their own chapters.
Road wheels are also now included in Suspension.
Example 2:
Fuel, emissions and exhaust is now in three different
chapters. Fuel has its own chapter and includes all fuel
aspects up to the fuel rails (Fuel rails and fuel injection now
come under Engine System). Exhaust, not including
manifolds, has its own chapter and Emissions now come
under the Engine system.
When required references are made out to other chapters.
Numbering
Chapters and sections within chapters are numbered using
the system detailed above. All technical manuals for this
vehicle use the same numbering system. When carrying out
a procedure, the relevant parts illustration and spare parts list
can be found using the same numbering system.
To avoid excessive repetition, each procedure is fully
detailed once in its appropriate chapter. In any other
location where this procedure is required, it is referenced by
its title and chapter / page number.
Special Tools
Where special service tools are required to perform an
operation, the tool number is recorded at the point of use
within the procedure. Where the operation of a special
service tool is complicated or not obvious, refer to the
Appendix and Glossary for detailed operation procedures. A
pictorial list of special service tools available for this vehicle
can also be found in the Appendix and Glossary.
Location References
References to left, right, front or
rear of the vehicle or of a
component are referenced from
sitting in the drivers seat facing
forward. Any such references to
assemblies removed from the
vehicle are to the normal
orientation of the assembly when
installed in the vehicle.
Warnings, Cautions
and Notes
The following Warnings, Cautions
and Notes are used within this workshop manual to call your
attention to specific types of information.
Warnings
Cautions
Notes
Repairs and Replacements
Where replacement parts are required, it is essential that
only genuine Aston Martin parts are used. Your attention is
drawn to the following points concerning repairs and the
fitting of genuine Aston Martin parts and accessories:
• Safety features embodied in the vehicle may be impaired
if other than genuine Aston Martin parts are installed. In
certain territories, legislation prohibits the installation of
parts which are not produced to the manufacturers
specification
• Adhere to torque wrench settings given in this manual
• Locking devices, where specified, must be installed. If the
efficiency of a locking device is impaired during removal,
it must be renewed
• The vehicle warranty may be invalidated by the
installation of other than genuine Aston Martin parts
03. 02.

Safety Precautions
Introduction
Issue 7, September 2011 Workshop Manual I-I-VII
Safety Precautions
All service workshops are a source of potential danger and
repair work should only be performed by technically trained
staff following procedures detailed in this manual. A safety
conscious approach to the performance of all service
procedures must be observed at all times. Statutory
requirements governing all aspects of health and safety at
work including directives for the proper use of materials and
equipment must be implemented.
The following headings highlight particular safety
precautions which should be observed (The list is not
intended to be exhaustive).
Battery Disconnection
Where a procedure requires the vehicle battery to be
physically disconnected (disconnect the vehicle battery
earth (Negative) lead), the following items will have to be
reset or re-learnt on connection:
• Seats memory
•Radio pre-sets
•DTCs will be lost
Air Conditioning (A/C) System
Do not break into the A/C refrigeration system until the
refrigerant has been evacuated using the procedure detailed
in this manual. Do not disconnect any A/C refrigerant system
pipes unless trained and instructed to do so. The refrigerant
used can cause blindness if allowed to contact your eyes.

Safety Precautions
Introduction
I-I-VIII Workshop Manual Issue 7, September 2011
Chemical Handling and Storage
Chemicals used in the servicing of motor vehicles include:
acids, adhesives, antifreeze, brake fluids, coolants, grease,
oil, paint, resin and solvents. Exposure to some chemicals
through direct contact or inhalation can cause injury or
death.
Potential hazards can also be present from the incorrect use,
storage and handling of chemicals. causing a fire risk.
Electrical Equipment
Exhaust Fumes
Engines must only be operated where there is fume
extraction equipment in operation or where there is
adequate ventilation.

Lifting and Jacking
Introduction
I-I-X Workshop Manual Issue 7, September 2011
Lifting and Jacking
Safety
Jacking Points
This vehicle jacking points are at positions shown.
The vehicle may also be jacked with the jack placed on the
front subframe, front crossmember.
Always use a jack with a rubber contact pad. Avoid the use
of jacks with sharp contact pads which could damage the
vehicle floor pan Always chock the opposite road wheels as
well as applying the handbrake when using a hydraulic jack.
To prevent body distortion, avoid single point or one side
jacking with the tunnel shear panel removed.
To avoid any danger of bodywork damage when using a
hydraulic jack, the vehicle must only be lifted at the jacking
points.
Stands
When carrying out work (other than a wheel change) which
requires a wheel to be raised, a stand must be used, located
at the jacking point, to provide a secure support for the
vehicle.
Workshop Hoist
Use of a workshop hoist is recommended for all operations
where vehicles must be raised. Follow manufacturers
instructions. If using an adjustable arm type, ensure lifting
pads are correctly positioned at the four jacking points
before lifting.
WARNING
OBEY THE LOCAL WORKSHOP REGULATIONS WHEN
YOU TOW OR LIFT A VEHICLE.
WARNING
DO NOT USE A JACK TO HOLD A VEHICLE WHEN
YOU DO WORK UNDER IT. ALWAYS USE A VEHICLE
LIFT, RAMP OR PIT WHEN YOU WORK UNDER THE
VEHICLE. IF YOU DO NOT, THE JACK CAN COLLAPSE
AND PERSONAL INJURY OR DEATH CAN OCCUR.
WARNING
WHEN YOU WORK UNDER A VEHICLE, CHOCK THE
WHEELS AND APPLY THE HANDBRAKE.
WARNING
MAKE SURE THAT THE VEHICLE IS ON FIRM, LEVEL
GROUND WHEN YOU JACK OR LIFT IT.
WARNING
DO A CHECK THAT THE LIFTING EQUIPMENT HAS
SUFFICIENT CAPACITY FOR THE LOAD BEING LIFTED.
MAKE SURE THAT THE EQUIPMENT IS IN GOOD
WORKING ORDER.
CAUTION
JACK THE VEHICLE ON THE LOWER SUSPENSION
ARMS (FRONT OR REAR).
Front Crossmember
