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 IMMOBILISATION SYSTEM - FROM 02MY
Engine immobilisation is available on all 2002MY engine derivatives, although it is not available in selected
markets. On Td5 models, the immobilisation system is controlled directly by the anti-theft alarm ECU. On 300Tdi
models, the immobilisation system is controlled by an engine immobilisation ECU in conjunction with the anti-theft
alarm ECU.
When immobilisation occurs on Td5 models, engine crank is disabled by the anti-theft alarm ECU breaking the
earth path for the starter relay coil and the ECM disables the fuel pump relay and the glow plug relay.
When immobilisation occurs on 300Tdi models, engine crank is disabled by the anti-theft alarm ECU breaking the
earth path for the starter relay coil and the engine immobilisation ECU disables the fuel cut-off solenoid, the starter
motor solenoid and the glow plug relay.
Two types of immobilisation are available; passive and active.
Engine Immobilised Warning Lamp
The engine immobilised warning lamp is located in the instrument pack. The lamp is used by the anti-theft alarm
ECU to show that the engine is immobilised during an attempted engine start.
The warning lamp receives a battery supply from the ignition switch position I (aux) via the passenger
compartment fusebox. The anti-theft alarm ECU controls the warning lamp. When the warning lamp is not
required, the ECU supplies a battery supply to the warning lamp. When warning lamp operation is required, the
ECU provides an earth for the bulb.
If the ignition switch is moved to the crank position, but operation of the starter motor is prohibited and the engine
immobilised warning lamp flashes, then the anti-theft alarm ECU has not received the correct code from the
remote handset and the vehicle will remain immobilised. Ensure that the remote handset is in the proximity of the
transponder coil. If the remote handset is not available or inoperative, the immobilisation system can be disarmed
using the EKA procedure outlined later in this section.
If the ignition switch is turned to the crank position III and the remote handset is not in the proximity of the
transponder coil, engine immobilisation will remain active and the warning lamp will flash to inform the driver.

DESCRIPTION AND OPERATION CENTRAL DOOR LOCKING (CDL) - FROM 02MY
The Central Door Locking (CDL) system is a new feature for 2002MY Defender.
NOTE: CDL operates all doors on Station Wagon and County Station Wagons. On all other
Defender 2002MY variants, CDL operates on the driver and front and rear passenger doors only.
General
CDL operates on all doors, including the tail door and is operated by pressing the appropriate button on the
remote handset, using the vehicle key in the drivers door lock or using the drivers door sill button.
The CDL system introduces electrically operated door latches which are controlled by the anti-theft alarm ECU,
located behind the instrument pack. The anti-theft ECU receives a permanent power supply from fuse 6 in the
passenger compartment fuse box. Each CDL latch motor is connected by two wires to the anti-theft ECU which
alternately supplies power and earth connections to drive each motor to the lock or unlock positions.
If the latch motors are continually operated in a short period of time, the anti-theft ECU will suspend all CDL latch
motor operation for 15 seconds to prevent the motors from overheating. Before suspension occurs the anti-theft
ECU ensures that all the doors are left in the unlocked condition.
If the vehicle is locked, and the key is in the ignition switch or the ignition is on and the anti-theft alarm ECU inertia
switch is tripped, all doors will be unlocked immediately and the hazard warning lamps will operate. To prevent
accidental relocking, all latch motors will be inhibited until the anti-theft ECU senses that the drivers door is
opened with the key removed from the ignition switch.
Locking of the vehicle using the remote handset is inhibited with the key in the ignition switch.
Slam Locking
With the introduction of CDL, slam locking of the drivers door is disabled. If an attempt is made to slam lock the
vehicle, the anti-theft alarm ECU will unlock all doors.
CDL Using the Drivers Door Sill Button
Each door has a sill button to allow that door to be individually locked from inside the vehicle. The drivers door sill
button has additional functionality which allows all doors to be locked from inside the vehicle from this one button.
When the driver door sill lock button is depressed, the CDL system enters a sill locked state, where all doors are
locked but immobilisation and perimetric and volumetric sensing is suspended. CDL using the drivers sill lock
button can be achieved with or without the key in the ignition switch and without the ignition being on.
If the CDL is in the sill locked state and the lock button on the remote handset is pressed, the volumetric and
perimetric functions of the alarm system will become active and active engine immobilisation will be invoked.

DESCRIPTION AND OPERATION Interior Lamp Functionality
The anti-theft alarm ECU controls the interior lamp functionality. When the lamps are extinguished, they fade out
to the off condition over a 2 second period.
The lamps are turned on by:
Disarming the alarm using the remote handset
Opening any door.
When the lamps are on, they will be extinguished by the following actions:
If all doors are closed, the lamps will be extinguished after a 15 second delay period
If any door is left open, the lamps will be extinguished after an 8 minute delay period
If one of the above delay periods is active and the ignition is switched on or the alarm is armed, the lamps will
be extinguished.
ANTI-THEFT ALARM SYSTEM SELF TEST
The anti-theft alarm ECU has a self test feature which allows all alarm inputs to be tested. To enter self test mode
the following steps must be completed as follows:
1.Ensure that the driver’s door is closed and the driver’s window is open
2.Open the bonnet and with assistance depress and hold the bonnet switch
3.Release the bonnet switch and within 0.5 seconds turn the ignition switch on to position II
4.Quickly open the driver’s door
5.Turn the ignition switch to the off position
6.Turn the ignition switch back to position II
7.If the self test mode has been entered successfully, confirmation will be given by the alarm sounder. If the
ECU has not entered self test mode, repeat the above procedure.
Once in self test mode, the following test inputs will cause the security LED to illuminate and the engine
immobilised warning lamp and the hazard warning lamps to flash. When an input is operated, non illumination of
the security LED, the engine immobilised warning lamp and the hazard warning lamps indicates a fault for that
input.
Perform the following steps to test each input for correct operation:
Close and open the drivers door
Open and close each of the passenger doors and the tail door in turn
Close and open the bonnet (depress switch if bonnet still open)
With drivers door closed, lock and unlock the driver’s door using the vehicle key if spare key available. If spare
key is not available, operate driver’s sill button through open window
Press the unlock button of the remote handset. This enters the volumetric self test mode and all other inputs
will be disabled. Make a movement inside the vehicle. When the volumetric sensor is triggered the security
LED will flash.
To exit the self test mode, turn the ignition switch to the off position.
