DE SCRIP TION AND OPERATIONANTI-THEFT ALARM AND CENTRAL DOOR LOCKING (CDL)
DESCRIPTION
Anti-Theft Alarm
The anti-theft alarm system fitted to New Range Rover consists three main areas:

Perimetric protection.

Volumetric protection.

Vehicle angle monitoring.
Perimetric Protection
The Body Control Unit (BCU) protects the outside of the vehicle by monitoring the condition 
of all four door switches, the bonnet switch, and the upper tail door switch and sounds the 
alarm if any are triggered.
Volumetric Protection
The BCU protects the inside of the vehicle via an volumetric sensor mounted in the centre 
of the headlining. If the volumetric sensor detects movement within the passenger 
compartment, it informs the BCU to sound the alarm. When the alarm is first armed, the BCU 
allows 15 seconds for the air within the passenger compartment to stabilise. The alarm will 
then become fully armed after a further 15 seconds.
Vehicle Angle Monitoring
The BCU protects against the vehicle being illegally towed away, or any of the wheels being 
stolen by measuring the longitudinal and transverse angle of the vehicle. The angle of the 
vehicle is monitored by the tilt sensor, which is located beneath the front passenger seat. 
When the vehicle is first armed, the tilt sensor stores the angle of the vehicle it its memory. 
If the angle changes more than 1.2° (longitudinal) or 1.4° (transverse), the tilt sensor informs 
the BCU to sound the alarm. After the alarm has been triggered once, the threshold is 
lowered to 1.1 ° and 1.3 ° to make the alarm even more sensitive to vehicle angle movement.
NOTE: If the upper tail door is unlocked using the RF transmitter, the tail door switch, 
volumetric sensor, and tilt sensor will be disabled. These will be reactivated 30 seconds after 
the tail door is closed and locked.
An anti-theft alarm LED is mounted in the rear view mirror to act as a visual deterrent. The 
flashing sequence of the LED is dependent upon the status of the anti-theft alarm system. 
For detailed information on the anti-theft alarm system, refer to the  Anti-theft Alarm and 
Central Door Locking  section of the Description and Operation Workshop Manual. 
						

							DESCRIPTION AND OPERATION
4.2RANGE ROVER
Central Door Locking (CDL) and Superlocking
Two levels of locking are available; Central Door Locking (CDL) and Superlocking. CDL 
locks all doors, the tail door and the fuel filler flap. Superlocking carries out the same function 
as CDL but also inhibits operation of the interior door handles and sill buttons.
Superlocking is activated when either the Radio Frequency (RF) handset or the key is used 
to lock the vehicle. CDL is activated if the CDL master switch mounted on the fascia is 
pressed.
The RF handset, which is incorporated into the head of the ignition key, has three buttons. 
Pressing the large Land Rover button once locks all doors and the tail door. This is followed 
by a single confirmation flash of the hazard warning lamps to inform that the vehicle has 
been locked successfully.
Pressing and holding the Land Rover button for longer than 2 seconds locks all the doors 
and tail door and also closes any open windows (including the sunroof). Completion of this 
is again followed by a single confirmation flash of the hazard warning lamps to inform that 
the vehicle has been locked successfully.
Pressing the unlock Arrow button once unlocks the drivers door. Pressing the unlock Arrow 
button a second time unlocks the remaining three doors and the tail door. Pressing and 
holding the Arrow button for longer than 2 seconds opens all the windows and the sunroof.
NOTE: Automatic opening and closing of the windows and sunroof is suspended if the lock 
or unlock button is released before the operation has been completed.
A third button on the handset operates the upper tail door lock. A single press of this button 
will unlock the upper tail door and temporarily suspend operation of the anti-theft alarm 
system. Once the tail door has been closed the tail door is automatically locked and the anti-
theft alarm system reinstated. This is confirmed by a single flash of the hazard warning 
lamps.
For a detailed description of the CDL system, refer to the   Anti-theft Alarm and Central 
Door Locking  section of the Description and Operation Workshop Manual. 
						

							DESCRIPTION AND OPERATION
RANGE ROVER 4.3
OPERATION
Anti-Theft Alarm
Power Distribution
Feed from the positive battery terminal (C0192) is supplied to fusible link 1, fuse 15, fuse 43, 
and fuse 53 (C0632) on an R wire. All are located in the passenger compartment fuse box. 
Fuse 15 (C0586) provides a constant battery feed to the Body Control Unit (BCU) (C0660) 
on an RS wire. The BCU (C0660) is earthed on an NB wire.
Fusible link 1 (C0588) provides a constant battery feed to fuse 14 of the rear fuse box 
(C2024) on an R wire. Fuse 14 (C2022) provides a constant battery feed to the radio 
frequency (RF) receiver (C0674) on an RB wire.
Fuse 43 of the passenger compartment fuse box (C0586) provides a constant battery feed 
to the following:

The Battery Backed-Up Sounder (BBUS) (C0666) on an RN wire.

The volumetric sensor (C0359) on an RW wire.

The tilt sensor (C0960) on an RB wire.
Fuse 53 of the passenger compartment fuse box (C0583) provides a constant battery feed 
to the ignition switch (C0099 on Td6 vehicles, C0028 on V8 vehicles) on an R wire. When 
the ignition switch is turned to the ignition position, current flows across the switch (C0099 
on Td6 vehicles, C0028 on V8 vehicles) to fuse 6 of the passenger compartment fuse box 
(C0585) on a G wire. Fuse 6 (C0587) provides an ignition feed to the interior mirror (C0698) 
on a GW wire.
RF Receiver
The RF receiver (C0674) is located at the top of the upper tail door, and is provided a 
constant battery feed from fuse 14 of the rear fuse box (C2022) on an RB wire. The RF 
receiver is connected to an element in the rear screen via a pair of B wires. The RF receiver 
uses the rear screen element as an aerial.
NOTE: The B wires connecting the RF receiver to the rear screen element are not shown on 
the system circuit diagrams as they are fly leads incorporated into the manufacture of the 
rear screen.
The RF receiver converts high frequency wave forms transmitted by the remote handset into 
bi-phase, pulsed signals that can be understood by the BCU. The RF receiver (C0674) is 
connected to the BCU (C0660) by a WY wire. 
						

							DESCRIPTION AND OPERATION
4.4RANGE ROVER
Volumetric Sensor
The volumetric sensor monitors the inside of the vehicle by emitting a series of ultrasound 
pulses, and measuring the profile of the returned echo. The sensor (C0359) is located the 
centre of the headlining, and is provided a constant battery feed from fuse 43 of the 
passenger compartment fuse box (C0586) on an RW wire. 
When the anti-theft alarm is armed, the BCU (C0661) switches on the volumetric sensor by 
providing a pulsed voltage signal to the tilt sensor (C0960) on a BS wire. This signal is 
relayed to the volumetric sensor (C0359) on a BW wire. If the volumetric sensor detects 
movement within the passenger compartment, it provides a feed to the BCU (C0661) on a 
BY wire. The volumetric sensor (C0359) is earthed on an N wire.
Tilt Sensor
The tilt sensor monitors the angle of the vehicle. If the angle of the vehicle moves more than 
the thresholds outlined in the  Description  section, the alarm will be triggered. The sensor 
(C0960) is located beneath the front passenger seat, and is provided a constant battery feed 
from fuse 43 of the passenger compartment fuse box (C0586) on an RW wire. When the 
anti-theft alarm is armed, the BCU (C0661) switches on the tilt sensor (C0960) by providing 
a pulsed voltage signal on a BS wire.
When the anti-theft alarm system is activated, the tilt sensor (C0960) provides a voltage 
pulse to the BCU (C0661) on a BU wire. If this isnt received within a set time, the BCU 
determines that the unit is defective.
If the tilt sensor is triggered, it provides a voltage pulse to the BCU (C0661) on a BU wire. 
Recognising this signal, the BCU (C0661) returns a pulsed voltage signal to the tilt sensor 
(C0960) on a BS wire. 
						

							DESCRIPTION AND OPERATION
RANGE ROVER 4.5
Battery Backed-Up Sounder (BBUS)
The BBUS (C0666) is mounted adjacent the brake servo, and is provided a constant battery 
feed by fuse 43 of the passenger compartment fuse box (C0586) on an RN wire. Dependant 
upon market configuration, the BBUS can emit one of three tones:

Continuous.

Pulsed.

Modulated.
When the anti-theft alarm is armed, the BCU (C0661) switches on the BBUS by providing 
a pulsed voltage signal to the tilt sensor (C0960) on a BS wire. This signal is relayed to the 
BBUS (C0666) on a BG wire.
When the alarm is triggered, the BBUS (C0662) provides a feed to the BBUS (C0666) on a 
BU wire. The BBUS (C0666) is earthed on an N wire. 
Perimetric Protection
The BCU (C0660) is located beneath the front passenger seat, and is provided a constant 
battery feed from fuse 15 of the passenger compartment fuse box (C0586) on an RS wire. 
The door, bonnet, and tail door switches are all normally open switches. When any of these 
panels are opened, the switch contacts close and an earth path is created. The BCU 
(C0660) monitors the condition of door bonnet and tail door switches as follows:

The BCU monitors the condition of the drivers door switch (C1449) via the drivers door 
module (C2058) on a UR then NW wire. The drivers door switch (C1449) is earthed on 
an N wire.

The BCU monitors the condition of the front passenger door switch (C1451) via the 
passenger door module (C2057) on a UR then NW wire. The passenger door switch 
(C1451) is earthed on an N wire.

The BCU monitors the condition of the LH rear passenger door (C0442) on an NS then 
NG wire. The LH rear passenger door switch (C0442) is earthed on an N wire.

The BCU monitors the condition of the RH rear passenger door (C0442) on an NW 
then NG wire. The RH rear passenger door switch (C0442) is earthed on an N wire.

The BCU monitors the condition of the bonnet switch (C0007) on a PG wire. The 
bonnet switch (C0007) is earthed on an N wire.

The BCU monitors the condition of the upper tail door switch (C0383) on an SW wire. 
The upper tail door switch (C0383) is earthed on an N wire.
NOTE: The LH rear and RH rear passenger door switches have the same connector number 
as they utilise the same harness.
Anti-theft Alarm LED
The anti-theft alarm LED is located in the rear view mirror. The flashing sequence of the LED 
(C0698) is controlled by the BCU (C0661) on an SBY wire.
