DESCRIPTION AND OPERATION SECURITY AND CENTRAL DOOR LOCKING
SYSTEM - FROM 02MY
The following description details the functionality and operation of the 10AS Security and Central Door Locking
(CDL) System fitted to 2002MY Defender. The system contains some new features and also retains some
features from previous Defender models. The alarm system and CDL system are controlled by the 10AS anti-theft
alarm ECU.
New door lock barrels are introduced and use the same key as the ignition switch barrel, thereby eliminating the
requirement for a separate key for the doors.
NOTE: Some markets will only have some of the features described and some will have no
security or central door locking functions.
The security system comprises the following components:
10AS anti-theft alarm ECU
Remote handset transmitters
Transponder coil
Volumetric sensor
CDL actuators
Bonnet switch
Driver’s door key barrel switch
Door switches
Bonnet switch
Battery Backed-Up Sounder (BBUS) or alarm sounder
Security LED
Engine immobilised warning lamp
Direction indicators

DESCRIPTION AND OPERATION ANTI-THEFT ALARM - FROM 02MY
The alarm and immobilisation system on 2002MY Defender is similar to that used on Discovery Series I (LJ)
models from 1996MY. The alarm system comprises the anti-theft alarm ECU, bonnet and door switches and a
volumetric sensor.
Anti-Theft Alarm ECU
The anti-theft alarm ECU is located behind the instrument pack and receives a permanent battery supply via fuses
6 and 7 in the under seat fuse box. The ECU also receives a battery supply via the ignition switch position II and
fuse 1 in the passenger compartment fuse box. The ECU is connected to the various supporting components by
two harness connectors.
The ECU controls the alarm system (perimetric and volumetric security), CDL system, engine immobilisation
system (Td5 only) and various other vehicle functions including direction indicators and interior lamps.
The anti-theft alarm ECU incorporates an RF receiver and antenna for reception of RF signals from the remote
handset for locking and alarm arming. The antenna is unterminated at one end, and for optimum performance the
antenna must not be wound around adjoining harnesses.
The anti-theft alarm ECU operates at one of two frequencies which are identified by a label on the unit. The
frequencies are:
433 MHz - Europe, Gulf States, South Africa
315 MHz - North America, South East Asia, Japan, Australia.
The anti-theft alarm ECU also incorporates an integral inertia switch. In the event of an impact of sufficient severity
to trigger the inertia switch when the ignition is on, the ECU will unlock all doors and operate the hazard warning
lamps. The ECU will remain in this condition for a pre-programmed period of 2 minutes. To reinstate CDL
functionality and to deactivate the hazard warning lamps, the ignition should be turned off and then on after the 2
minute timer has expired.
NOTE: There is a separate inertia switch for fuel cut off.

DESCRIPTION AND OPERATION Alarm Sounders
1.Battery Backed Up Sounder (BBUS)
2.Alarm sounder
Two types of alarm sounder are available, dependant on the vehicle market configuration.
A Battery Backed-Up Sounder (BBUS) is used in some markets and located in the LH front wing, behind the
headlamp. This is a tamper proof sounder with its own power supply which allows it to continue operating even if
disconnected from the vehicle power supply. The BBUS is connected to a permanent battery supply via fuse 7 in
the under seat fuse box. Two further connections are made to the anti-theft alarm ECU and a fourth connection is
to an earth header. If the BBUS is disconnected without first being disarmed by the anti-theft alarm ECU, it will
operate for 4.5 minutes.
To disarm the BBUS, when the battery is to be disconnected for instance, the ignition must be turned on to
position II and back to the off position , after which a 17 second delay is initiated to allow the battery or BBUS
connector to be disconnected. If the BBUS sounds, it can be disarmed by unlocking the vehicle with the remote
handset.
Where a BBUS is not specified, a standard vehicle horn is used for the alarm sounder and is located in the LH
front wing, behind the headlamp. The sounder is operated by an alarm relay which is controlled by the anti-theft
alarm ECU. The relay receives a permanent battery supply via fusible link 6 in the under seat fuse box. The relay
coil is connected to the anti-theft alarm ECU which provides an earth for the coil when horn operation is required.
This operates the relay contacts and supplies battery voltage to the sounder, causing it to operate.

DESCRIPTION AND OPERATION Visual and Audible Warnings
Audible and visual warnings are dependant on market legislation. The hazard warning lamps are controlled by two
outputs from the anti-theft alarm ECU; one for the LH lamps and one for the RH lamps. To illuminate the warning
lamps the output from the ECU is at battery voltage. When the lamps are off, the output is driven to earth.
When the alarm is armed the hazard warning lamps will flash three times to indicate that the system is active.
When the alarm is triggered the sounder will operate in either a pulsed or continuous tone (dependant on market
legislation) and the hazard warning lamps will flash at 0.5 second on/off intervals for 30 seconds. The alarm
system can be triggered for up to three times in any one alarm armed cycle. When the alarm system is disarmed
confirmation will be by one single flash of the hazard warning lamps for 0.3 seconds.
If the hazard warning lamps are active when an alarm trigger is active or the alarm is armed, the visual alarm
active visual warning using the hazard warning lamps will be cancelled.
In addition to the visual and audible warnings, the security LED in the instrument pack also displays alarm system
status information.

DESCRIPTION AND OPERATION Security LED
The security LED has a number of functions to indicate anti-theft alarm system status. The LED is located in the
speedometer housing in the instrument pack. The LED receives a permanent battery supply via fusible link 6 in
the under seat fuse box. The LED is connected to the anti-theft alarm ECU which earths the connection when LED
operation is required. When the LED is not required to be illuminated, the anti-theft alarm ECU holds the
connection at battery voltage, keeping the LED extinguished.
When the system is armed and the bonnet and all doors are closed, the LED flashes quickly for a 10 second
confirmation period and confirms that perimetric and volumetric systems are armed. After the 10 second
confirmation period the LED flash changes to a slow flash to confirm that the alarm and immobiliser systems are
armed and to act as deterrent to thieves.
The LED also conveys CDL system information and this functionality is described in the Central Door Locking
(CDL) section.
