Safety Precautions
Safety Precautions (continued)
Electrical Equipment

1.
Ensure that electrical equipment is in safe working order before use.

2.
Inspect power leads of all mains electrical equipment for damage and security, and check that it is properly

earthed.

3. Ensure that electrical equipment is protected by a fuse of the correct current rating.

4.
Disconnect the battery before commencing repair operations to the electrical system, fuel system and engine
or when working beneath the vehicle.
Exhaust Fumes
Engines should not be run in confined spaces, exhaust fumes contain harmful and toxic substances including carbon
monoxide which can prove fatal if inhaled. Engines must only be run where there is fume extraction equipment in
operation or where there is adequate ventilation.
Fire Precautions

1.
Ensure that a suitable form of fire extinguisher is conveniently located near the work area.

2.
Keep oils, solvents and combustible materials away from naked flames and other sources of ignition.
3. Ensure that NO SMOKING signs are posted around areas where combustible materials and vapour may be
present and ensure that the warnings are strictly observed.

4.
Ensure that dry sand is available to soak up any spillage of fuel or other flammable solutions.
5. Fume extraction equipment must be available and in full working order to remove combustible and toxic
vapours.
6. All personnel should be aware of the fire drill procedures and precautions.
Jacking and Lifting

1.
The recommended procedures for lifting, jacking and towing are included latefin this seetion-and must be
strictly observed to ensure personal safety.

2.
Always use a vehicle hoist, ramp or pit for working beneath the car in preferencetd^&^cking
3. Never rely on a jack to support a car independently, use axle stands or blocks carefully pJaQed at the jacking
points to provide rigid support.

4.
When working beneath a vehicle, chock the wheels as well as applying the handbrake.
5. Ensure that the vehicle is standing on firm level ground before jacking or lifting.
5. Check any lifting equipment used has adequate capacity for the load being lifted and is ih"fdll working order.
Tools and Equipment

1.
Do not leave tools, equipment, spilt oil, etc. around or on the work area.

2.
Ensure that tools and equipment used are in good condition; do not use damaged or defective tools or
equipment.
3. Do not apply heat in an attempt to free stiff nuts or fittings; as well as causing damage to protective coatings,
there is a risk of damage to electronic equipment and brake lines from stray heat.

4.
Use the recommended service tool where instructed to do so.

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.
6.7.03 Door Central Locking Motors

1.
Remove the door inner panel.

2.
Disconnect two plugs on the central locking motor
unit and one plug on the door closed switch.

mechanism.

4.
Disconnect the outer lock operating rod.
5. Remove three lock securing screws from the door
rear edge.
6. Remove the motor and lock through the access

hole.

7. Remove the motor securing screws and remove the
motor from the lock assembly.

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.
