Procedure Numbering
The workshop manual procedures
are
numbered using
the
parts list numbers
as a key. The
first
two
digits
oi a
workshop manual procedure number
are
also
the
parts list number
(e.g.
1.5.01
Sump Removal relates
to PL 1.5 Oil
Pump
and
Sump). Thus when carrying
out a
procedure,
you can
quickly locate
the
relevant parts illustration
and
spare parts list.
To avoid excessive repetition, each procedure will
be
fully detailed once
in its
appropriate place
in the
manual.
In
any other location where this procedure
is
required,
it
will
be
referenced only
by its
title
and its
procedure 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.
An
index
and
illustrated list
is
provided
in
this section
for the
purpose
of
identifying special
tools.
References
References
to the
left, right, front
or
rear
of
the vehicle
or of
a component
are
always made as
if
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 fitted
in the
vehicle.
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
fitted.
In certain territories, legislation prohibits
the
fitting
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
fitted.
If the
efficiency
of a
locking device
is
impaired during
removal,
it
must
be
renewed.
•
The
vehicle warranty
may be
invalidated
by the
fitting
of
other than genuine Aston Martin parts.

Central Locking System
Description
Thecentral locking system consistsofmotoroperated lock
actuators in both doors, the boot and the fuel flap
mechanism. The central locking control module is located
inside the drivers side 'A' post.
Each motordriven lock actuator incorporatesa microswitch
which will signal a change of state when any motor runs
to drive the actuator. The microswitches are of the
changeover type and provide an earth for the lock or
unlock signals to the control unit.
The two door lock inputs to the control unit are connected
together so that operation of either door lock with the
ignition key will simultaneously operate the other door
lock. Similarly, the unlock inputs to the control unit are
also connected together for simultaneous operation.
The boot will remain locked or will be unlocked
simultaneously with the doors dependant on the boot lock
position.
With the boot key turned clockwise, the boot
lock operates in unison with the doors. With the boot key
turned anticlockwise, the boot lock cannot be unlocked
using the central locking system.
The boot can be opened at any time using the ignition key
irrespective of the central locking status.

Electric Windows - Fault Analysis / Window Motor Removal
[n:m3^^
Electric Windows
Description
Power to the window wind circuits is available
when the ignition switch is on and is supplied
through a thermal cut-out to the left and right
window switches. The switches are double pole
plus earth so that the current through a window
motor may be switched in either direction to raise
or lower the window.
DB7 uses frameless door windows which seal
against rubber strips around the body shell door
opening.
To avoid damaging these seals during
door opening, the door glass must be lowered
before the door can be opened. This function is
controlled by the window control units. The units
are mounted on the inside of each door frame and
will sense if a door handle is pulled to open the
door. Before releasing the door lock, the control
unit will drive the window wind motor briefly to
lower the door window glass down until it clears
the window seals. Similarly, after closing a door,
the window motor will be run to raise the door glass
to seat the glass against the body seals.
Fault Analysis Procedure
a) If a window fails to operate, check for fuse failure
and the connectors for poor or open contacts.
b) Check the thermal cut-out by shorting across it and
operating either window. If the windows operate
with the short
ci rcu
it but not without, the cut-out is
faulty.
c) With the ignition on, battery voltage should be
available between the inputterminalsof the switches
and chassis. Operate each switch and ensure that
battery voltage is available between the switch
output terminals and chassis.
d) Measure voltagefrom each switch inputterminalto
the switch earth return terminal. If no voltage is
measured,
the earth return line is open circuit.
e) Measure continuity through the wiring from the
switches to each motor. If continuity is correct,
remove the motor for bench testing.
6.7.04 Door Window Motor
Procedure
1.
Remove the door trim panel and the glass inner
sealing
trim.
Figure!. Window Securing Screws
2. Position the window to gain access to the slider
bracket and glass securing screws.
3. Disconnect the battery earth
lead.
4.
Remove two screws securing the glass to each of
the two slider brackets. Loosen the two screws
securing the glass to the elevator
rail.
6. Slide the elevator rail forwards until the glass
securing screws are opposite the wide opening of
the rail keyhole slots and remove the glass from the
top of the door.
7. Disconnect the window motor multiplug.

location and electrical wiring diagrams.
Component Index
The following list details all of the functional
electrical components of the DB7. The list is given
in alphabetical order with component location and
wiring diagram references for each component.
Component Location on the vehicle
To locate a component on the veh
icie,
find its name
in the component index and note the component
location reference.
The component location reference gives the figure
number and item number for each component so
that you can find the component on the following
location diagrams and in the car.
Component Location on the Wiring Diagrams
The wiring diagram reference gives the wiring
diagram number and the location coordinates so
that you can locate the component and its wiring
on the wiring diagrams.
Wiring Diagrams
Each diagram covers a complete loom or section of
a major loom.
Continuations of a loom on another sheet and
connections to other looms are indicated by the
continuation arrow »* and the Sheet Number and
Co-Ordinateswherethecontinuation or connection
is located.
Each connector is illustrated with an end view of
the mating face of the connector. A table beside
each connector gives the pin number, wire colour
and destination of each wire.
Wire Colours
The following key is used to denote wire colours in
the connector wiring tables
B = Black P = Purple G = Green
K = Pink S = Slate LG = Light Green
N = Brown W = White O = Orange
R = Red U = Blue Y = Yellow
Wire Splices
Many wire runs are spliced within the loom
wrapping and additional information is required to
aid in fault analysis. All splices are noted on the
wiring diagrams (e.g. SPL1 = Splice 1). On the
facing page for each wiring diagram, a splice list
gives the splice number and the wire colours and
destinations for each wire coming from the splice.

Airbag System
Eye Protection
Chemical protective goggles are recommended
where there is a possibility of eye contact with the
propellant. Safety glasses with side shields are
recommended for all other operations.
Protective Clothing
Approved protective gloves, overalls and shoes/
boots should be worn.
Handling and Storage Precautions
Do not store airbag modules near live electrical
equipment or circuitry. Store in a dry environment
at ambient temperatures.
Good housekeeping and engineering practices
should be employed to prevent the generation and
accumulation of
dusts.
Store in compliance with all
local state and federal regulations.
Driver and Passenger Airbag Modules
Assembly/Removal/Service Instructions
WARNING: In the event of a vehicle impact where the
airbags and the seatbeltpretensioner (if fitted) are
deployed, the following actions MUST be
performed:
Check the condition of the seatbelts, steering
wheel,
steering column, all connections to airbags,
and the column switchgear connectors for integrity
and damage. If in any
doubt,
replace suspected
parts for new parts.
Replace both crash
sensors,
the
safing sensor
and
the seatbelt pretensioner module (if fitted).
On completion of all repair procedures, switch on
the ignition and check that the
Airbag/SRS
warning
light comes on when the ignition is switched on
and extinguishes after approximately six seconds
indicating satisfactory completion of the airbag
and pretensioner
system
self
tests.
WARNING: Before starting
work,
ensure
that the ignition
switch is in position 'O' and the ignition key is
removed.
Disconnect the battery negative lead
within 12 seconds of switching off the ignition to
prevent the alarm system triggering.
As the airbag control module is equipped with a
back-up power source and due to the risk of the
airbag being inadvertently deployed, wait one
minute or longer after disconnecting the battery
before starting work on the airbag module.
• Disconnectingthe battery negative cable cancels
the memory for the 'one-touch' window down
system and stops the vehicle clock. Reset the
window memory and the clock when work is
completed.
• Never use airbags from other vehicles, always
use new parts.
• After work is completed, reconnect the battery
and perform the airbag warning light check
• Never use electrical probes to check voltage or
electrical resistance of the airbag modules.
• Disconnect the airbag before carrying out any
work on, or in the vicinity of the module, or
when using electric welding equipment.
• Always ensure that the battery negative lead has
been disconnected for at least one minute before
commencing any removal procedure.
