1999 LAND ROVER DISCOVERY lock

ALARM SYSTEM AND HORN
DESCRIPTION AND OPERATION 86-4-23
In order for speed related locking to activate the following conditions must be met:
lAll doors unlocked.
lEngine running.
lVehicle speed greater than 4 mph (7 km/h).
Acclimatisation related locking
Acclimatisation related locking allows the engine to be started and then the vehicle locked with a spare key and left
unattended to allow the vehicle interior to reach the desired temperature.
There are two configurations for acclimatisation related locking:
lAcclimatisation related locking not active.
lAcclimatisation related locking active.
Once the engine is started, the vehicle is locked with a spare key at the driver's door while the engine is running.
During these conditions the alarm is not armed.
In order to activate acclimatisation related locking the following conditions must be met:
lEngine running.
lAll doors closed.
Visual warnings
The direction indicators serve as a visual indication when the alarm is triggered. The direction indicators are also used
as a visual indication during lock/unlock procedures.
There are three configurations of alarm armed/disarmed indication:
lNo direction indicators on, alarm armed/disarmed/trigger.
lDirection indicators on, alarm trigger only.
lDirection indicators on, alarm armed/disarmed/trigger.
Dependent on system configuration the direction indicators flash one short pulse to confirm that the alarm is armed
and flash two short pulses to confirm that the vehicle is super locked. If the alarm is triggered the direction indicators
operate in phase with the audible warning. When the alarm is disarmed, the direction indicators flash one long pulse.
Audible warning
An audible warning device is used to indicate that the alarm has been triggered, or a mislock has occurred, or an EKA
request has occurred, or the EKA code has been entered.
There are six audible warning configurations:
lNo sound (audible warnings disabled).
lAlarm sounder only.
lVehicle horn only.
lAlarm sounder and vehicle horn.
lBBUS only.
lAlarm sounder, vehicle horn and BBUS.
Depending on which market the vehicle is sold, either the vehicle horn, a specific alarm sounder, or a BBUS operates
in phase with the direction indicators when the alarm is triggered. The audible warning device operates for
approximately 30 seconds at 0.25 second on, and 0.25 second off. The BCU allows the alarm to be triggered up to 3
times in any armed period.
Theft deterrent LED
An LED located in the instrument pack indicates the status of the alarm system.
There are eight theft deterrent alarm configurations:
lNo handset low battery warning.
lHandset low battery warning.
lNo passive immobilisation.
lPassive immobilisation.
lEngine immobilised (ignition off, LED off).
lEngine immobilised (ignition off, LED flashes).
lNo alarm tampered indication.
lAlarm tampered indication.

ALARM SYSTEM AND HORN
86-4-24 DESCRIPTION AND OPERATION
The theft deterrent LED utilises a particular flash to show the status of the following:
lAlarm armed.
lEngine immobilised.
lAlarm tampered.
lHandset low battery warning.

To prevent excessive battery drain during transportation to overseas markets, the vehicle is placed in a transit mode
at the end of line test.
The following functions are disabled when the vehicle is in transit mode:
lVolumetric sensors.
lPassive immobilisation.
lMobilisation of the vehicle by use of door lock.
lIgnition key interlock.

DESCRIPTION AND OPERATION 86-6-27
Operation
DVD Player Functionality
The following defines the functionality of the unit. Further details of system operation can found in the DVD System
Owner's Manual, Publication Part No. LRL0482, supplied with the system.
DVD Region Selection
The DVD player is capable of playing discs from any region. The DVD can only be set to play discs of one region at
a time. A code is entered using the remote control handset to set the unit to the required region. The unit is set to the
correct region on production and therefore this will not be required by either the dealer or the customer.
If the unit region is required to be changed for any reason, Land Rover Special Vehicles must be contacted for the
required code and procedure.
NOTE: The unit can be re-configured for region up to five times. After the fifth attempt to re-configure the region, the
unit will be locked in the fifth region that was programmed. This will require the unit to be returned to the manufacturer
to be reset. The manufacturer will charge a fee for this service.
DVD Player CD Audio Function
The DVD player can play audio CD's through the vehicle audio system. This allows the user to play additional CD's
without having to remove the CD autochanger cartridge.
The overhead console LCD monitor must be open to play audio CD's.. Normal audio CD functionality such as repeat,
random and track select etc. can be accessed using the remote control handset.
The DVD player in the overhead console will also function independently of the vehicle audio system, and operate as
an additional CD player. The rear seat passengers can listen to audio CD's via the three headphone sockets on the
overhead console and via the two radio/headphone amplifier units (if fitted), while the front seat passengers
simultaneously listen to CD's played on the vehicle audio system and CD autochanger.
DVD/CD Output using the Vehicle Audio System
To play the DVD/CD audio output from the overhead console through the vehicle audio speakers, the speaker button
on the overhead console or remote control handset must be pressed. 'Speaker On' appears on the LCD monitor and
the head unit CD functionality is suspended. The audio output from the overhead console will now be played from the
vehicle speaker system. The head unit volume control, tone control, Navigation announcements and mobile phone (if
fitted) will function as normal and override the DVD output. A second press of the speaker button will switch the audio
output back to the head unit. 'Speaker Off' will be displayed on the LCD monitor.
The overhead console will remember the selected speaker condition if the overhead console is switched off by closing
the monitor, the console switched off using the handset or accessory power removed from the overhead console.
Power Up Conditions
On application of accessory power, the overhead console will perform the following:
lIf no disc is in the DVD player, the LCD monitor will display a blue screen and enter 'AUX' input mode.
When a DVD or CD is inserted in the DVD player, the system will change to DVD input mode. The disc will
attempt to play but may be limited by the disc media. Some discs will play automatically, some will display a menu
and others require the user to start playback.
lIf a disc was in the DVD player and the system was in 'Play', 'Pause', 'FF' or 'Rew' when powered down, playback
will start when power is re-applied.
lIf a disc was in the DVD player and the system was in 'Stop' when powered down, the system will enter DVD
mode and a blue screen will be displayed on the LCD monitor.
lSpeaker selection will remain in the same state as when the accessory power was removed.
Engine Cranking
If the unit is playing a DVD or CD when the ignition switch is moved to position III (engine crank), the system will stop
playing while the engine is cranking. Playback will resume at the point the playback was stopped when the ignition
switch is returned to position I or II.
