DESCRIPTION OF MANUAL

Circuit Operation And Diagram

The Circuit Operation information at the beginning
of the section will give you an overview of how the
circuit works.
The Circuit Diagrams should always be your
starting point in using this Electrical
Troubleshooting Manual. The diagram shows the
electrical current paths when a circuit is operating
properly. It is essential to understand how a circuit
should work before trying to figure out why it
doesn't. Diagrams are shown with the Ignition
Switch in the OFF position and other switches in the
OFF or 'at rest' position.
Notes are provided after certain switches to clarify
switch positions. Abbreviations found in the notes
are explained in the Abbreviation Table found in the
SYMBOLS section of this chapter.
Circuit Diagrams (schematics) break the entire
electrical system into individual circuits. Electrical
components that work together are shown together.

connected to the output of the fuse. The Fuse
Details diagrams are extremely helpful in locating a
short circuit that causes a fuse to blow. These
diagrams also aid in troubleshooting an inoperative
circuit by showing a second circuit using the same
fuse. If the second circuit works, then the fuse and
certain wires of the inoperative circuit are good.

Ground Distribution
The Ground Distribution diagrams are found in
Section Y5. These diagrams show which
components share each ground point. This
information can often be a time-saver when
troubleshooting a poor ground.
For example, if the Fuel Pump does not run, you
may suspect an open in its circuit to ground.
However, if the Number Plate Lamps work, and they
share the same ground point as the Fuel Pump, you
know that the ground and the wire up to the
common splice are good. You have learned this
just by inspecting the diagram and knowing the
vehicle's symptoms.

shared wiring is OK. The cause must be within the
wiring used only by the problem circuit. If several
circuits fail at the same time, chances are the power
(fuse) or ground circuit is faulty.
(3) Find the Cause
• Narrow down the possible causes.
• Before you replace a component, check power,
signal, and ground wires at the component
harness connector.
(4) Repair the Problem
Once the specific problem is identified, make the
repair. Be sure to use the correct tools and safe
procedures.
(5) Check the Repair
Check the operation of the repaired circuit in all
modes to make sure you fixed the entire problem.
If the problem was a blown fuse, be sure to test all
of the circuits on that fuse. Make sure no new
problems are present.

TEST EQUIPMENT
Where applicable, Land Rover recommended
testers should be used.

Voltmeter and Test Light

Use a voltmeter or test light to check for voltage.
While a test light shows whether or not voltage is
present, a voltmeter indicates how much voltage
there is.
CAUTION: A number of circuits include solid-state
devices. Voltages in these circuits should be tested
only with a 1O-megohm or higher impedance

II INTRODUCTION

CAUTION: Never use a self-powered test light on

circuits that contain solid-state devices. Damage
to these devices may result.
Diodes and solid-state devices in a circuit can
make an ohmmeter give a false reading. To find out
if a component is affecting a measurement, take
one reading, reverse the leads, and take a second
reading. If the readings differ, the component is
affecting the measurement.
Circuits that contain solid-state devices should
only be tested with a 10-megohm or higher
impedance digital multimeter.
A self-powered test light consists of a light bulb,
Battery and two leads. If the leads are touched
together, the bulb will go on.
A self-powered test light is only used on an
unpowered circuit. First, disconnect the battery or
remove the fuse that feeds the circuit you are
working on. Select two points along the circuit
through which there should be continuity. Connect
one lead of the self - powered test Iight to each
point. If there is continuity, the test light's circuit will
be completed and the bulb will go on.

Fused Jumper Wire

Use a fused jumper wire to bypass an open circuit.
A fuse jumper wire is made up of an in-line fuse
holder connected to a set of test leads. Never use
a jumper wire across any load. This direct battery
short will blow the fuse.
The following symbol represents a fused jumper:

CIRCUIT OPERATION
Camshaft Position Sensor (Z262)
This is a Hall Effect sensor producing one pulse for
Sensors every two revolutions. The Signal is used in two
Engine Fuel Temperature Sensor (X128) areas: Injector timing corrections for fully sequential
fuelling and active knock control.
This is a resistive sensor, located on the fuel rail and
measuring the temperature of the rail rather than the Camshaft operation is essential to continue normal
fuel. The signal is used to increase the injection ignition, i.e. actuate the fuel injectors in the normal
pulse times when undergoing hot restarts. When the sequential order, timing the injection correctly with
fuel is hot, vaporisation occurs in the rail and a respect to top dead centre. In this way the sequential
"bubble" could form within the injectors. Increasing fuelling will either be correct, or one engine

the fuel rail with fuel from the tank.
Knock Sensors (X309, X31 0)
The knock sensor is a "Piezo-electric
accelerometer," i.e. it produces an output voltage
proportional to mechanical vibration produced by the
engine. The Engine Control Module (ECM) (Z132)
receives the signal, filters out any noise and
calculates if the engine is knocking. Due to the cam
and crank signals supplying information regarding
the position of the engine in it's cycle, the ECM
(Z132) can work out exactly which cylinder is
knocking and retards the ignition on that particular
cylinder until the knock disappears. It then advances
the ignition again to find the optimum ignition point
for that cylinder for those conditions (i.e. fuel type,
air temperature etc.). The ECM (Z132) will be able to
adjust cylinder timing for knock simultaneously, so
that all eight cylinders could have different advance
angles at the same time.
Coolant Temperature Sensor (X126)
A temperature dependant resistive metal component
is the major constituent of this sensor, i.e. the
resistance of the metal strip varies quite
considerably with temperature. The coolant sensor
signal is vital to correct engine operation, as the
injected fuel quantity is dependant upon the engine
temperature, i.e. richer mixture at low temperatures.
Intake Air Temperature Sensor (X311)
This is a resistive sensor, i.e. the change in
resistance is related to change in air temperature.
The signal from the Intake Air Temperature Sensor
(X311) is used to retard the ignition timing if the air
temperature rises above 55°C.
Crankshaft Position Sensor (X250)
The Crankshaft Position Sensor (X250) is a very
important sensor, as the signal it produces tells the
ECM (Z132) that the engine is turning, how fast it is
turning and at which stage the engine is at in the

Mass Air Flow Sensor (X105)

The sensing element of a Mass Air Flow Sensor Idle Air Control Valve (M112)
(X105) is a "hot wire anomometer" consisting of one The Idle Air Control Valve (M112) controls the idle
heated wire. The air flows across the hot wire, speed of the engine by moving the plunger a set
cooling the wire and thereby altering its resistance. distance, known as a step. Fully open is 200 steps
The ECM (Z132) measures this change in resistance and fully closed is 0 steps. The motor moves each
and so calculates the amount of air flowing into the step by sequentially changing the polarity to each of
engine. the two coils.
If the Mass Air Flow Sensor (X105) fails, the engine
will start and then die as the engine reaches 550 rpm
before the ECM (Z132) looks for the Mass Air Flow
Sensor (X105) signal.
Throttle Position Sensor (X171)
This sensor is a variable resistor. The signal informs
the ECM (Z132) of the actual position of the throttle
plate. Failure of the Throttle Position Sensor (X171)
will result in poor idle and lack of throttle response. If
the Throttle Position Sensor (X171) fails in the
"closed" mode, then the engine will only rev up to
1740 rpm when the ECM (Z132) will initiate "over run
fuel cut-off".
Heated Oxygen Sensors (X139, X160, X289, X290)
The heated oxygen sensor consists of a titanium
metal sensor surrounded by a gas-permeable
ceramic coating. Oxygen in the exhaust gas diffuses
through the ceramic coating on the sensor and
reacts with the titanium wire, altering the resistance
of that wire. From this change in resistance, the
ECM (Z132) can calculate the percentage of oxygen
in the exhaust gas and adjust the injected fuel
quantity that as to achieve the correct air/fuel ratio.
This reduces the emissions of Carbon Monoxide
(CO), Hydrocarbons (HC) and oxides of Nitrogen
(NOX) to acceptable levels.
Presently, two heated oxygen sensors are used, one
in each exhaust down pipe just before the catalyst.
In the event of sensor failure, the system will default
to "open loop". Operation and fuelling will be
calculated using signals from the remaining ECM
inputs. The fault is indicated by illumination of the
malfunction indicator lamp (MIL). ECM diagnostics
also uses heated oxygen sensors to detect catalyst
damage, misfire and fuel system faults.
North American vehicles have two extra heated
oxygen sensors mounted one after each catalyst.
These are used to determine whether the catalysts
are operating efficiently.

system (MPI) i.e. one injector for each cylinder no fuel, sparks, tacho reading, etc.
(compared to "single point" injection or throttle body
injection which uses one injector only). A fuel injector
consists of a small solenoid which is activated by the
ECM (Z132), allowing fuel to pass into the
combustion chamber. Due to the fuel pressure in the
rail and the shape of the injector orifice, the fuel
squirts into the cylinder in a fine spray to aid
combustion.

Relays
The engine management system uses four relays:
- Starter motor, ECM (Z132) power supply (main
relay), ignition and fuel pump, all located within the
fuse box.
Main Relay
This relay supplies the power feed to the ECM
(Z132) with a tap off to feed the fuel injectors and air
flow meter. This relay is controlled by the ECM
(Z132) itself, so that the ECM (Z132) remains
powered up after the ignition is removed and the
ECM (Z132) can record all temperature readings and
motorise the Idle Air Control Valve (M112) to the fully
open position. This is known as the "ECM (Z132)
power down routine". Failure of this relay will cause
the ECM (Z132) to not be switched on, resulting in
absence of fuel and spark and therefore a failed
start.

as well as slight fuelling effects. These symptoms
may not be noticeable.
CIRCUIT OPERATION
Air Temperature Sensor (X311)
This sensor is another thermistor, located in the inlet
Sensors manifold, just after the intercooler, and measures the
Engine Speed Sensor (X255) actual temperature of the turbo booster air entering
the engine. To calculate the maximum amount of

of the strategies within the 'DOE' (Digital Diesel bulky, heavy and expensive air flow meter is
Electronics) and its Engine Control Module (ECM) necessary, but the ECM (Z132) can calculate the air
(Z132). Through this sensor, the ECM (Z132) knows flow from the air temperature and air pressure, so

sensed on the flywheel (the flywheel has six 'teeth').
If the sensor fails, then the warning lamp is activated
and the ECM (Z132) enters a 'limp home' mode
where the ECM (Z132) looks at the signal from the
needle lift sensor in one of the injectors. The needle
lift sensor gives one pulse per injection, i.e. one
pulse per twelve engine speed sensor pulses. The
response of the ECM (Z132) to changes in engine
parameters will, therefore, be considerably slower,
and a higher idle speed is initiated to try to
compensate at low engine speeds.
Needle Lift Sensor (X318)
The engine has six diesel fuel injectors, one of which
has a sensing element at the tip which informs the
ECM (Z132) exactly when the injector fires (the
'beginning of injection' signal). The ECM (Z132) uses
this to correct the injection timing and also to back
up the engine speed signal in case that sensor fails.
If this sensor fails, the warning lamp will switch on
and the vehicle will enter 'limp home' mode with
reduced engine power/performance and lack of
throttle response (as there is a lack of feedback on
the injection timing).
Engine Coolant Temperature Sensor (X126)
This sensor is a 'thermistor' (a temperature
dependent resistor) where the voltage output varies
in proportion to coolant temperature. The ECM
(Z132) uses this information in many strategies, i.e.
to correct the injected fuel quantity and timing
(especially during cold starts), length of glow plug
timing, etc. The sensor is located in the top of the
engine block. In case of a failure, the warning lamp
is not activated and the ECM (Z132) selects a
substitute value of 50°C for glow plug and ignition
timing and uses the fuel temperature to correct the
fuel quantity, glow plug timing will not be correct,
possibly resulting in long crank times in cold weather

Boost Pressure Sensor substitute value of 60°C and only slight effects on
fuelling may possibly be noted.
The boost pressure sensor signal is used in
conjunction with the air temperature signal to Fuel Quantity Feedback Sensor

Throttle Position Sensor (X171) sensor, also takes place.
The DOE system is a 'Drive by Wire' system i.e. the
throttle pedal does not directly control a throttle disc
or the amount of fuel injected into the engine, but
accelerator movements or 'drivers request' are
sensed and the information is passed to the ECM
(Z132). The ECM (Z132) calculates the maximum
allowable fuel quantity from the air flow into the
engine, engine speed, temperature, etc. It also
includes information from strategies such as smoke
limitation, active surge damping, automatic gear
change, fuel reduction, etc. to calculate the final
figure. When driving, if the 'drivers request' signal is
smaller than the maximum allowable quantity, then
the requested quantity is injected. However, if the
requested quantity is greater than the maximum
allowable, then the latter quantity is injected rather
than the driver's demand. Therefore the Throttle
Position Sensor (X171) is very important to the
system. It is located within the cab, close to the
pedal assembly itself. The unit consists of a
potentiometer and has three outputs:
1. Throttle Position - pin 37 ECM (Z132)
The sensor outputs the pedal position to the ECM
(Z132), which uses the information as described
above.
2. Idle Position Switch - pin 25 ECM (Z132).
The sensor has a separate idle position switch which
informs the ECM (Z132) of the pedal status in the
form of a simple on/off signal. This information is
used by the ECM (Z132) to implement 'idle speed
control' and other strategies i.e. 'overrun fuel
shut-off'.
3. Kick Down Switch.
This switch is currently not used.
Fuel Temperature Sensor
A thermistor is also located inside the injection
pump. The fuel temperature sensor signal is used to
adjust the quantity of injected fuel, especially during
temperature extremes. The signal is also used to
back up the Engine Coolant Temperature Sensor
(X126). If this sensor fails, the ECM (Z132) uses a

is used. Surging will reduce so as to be hardly
noticeable.
Fuel Quantity Actuator
Once again located within the injection pump, this is
a moving magnet actuator, failure of which will cause Theft Alarm
the engine to stall or not start as the ECM (Z132) will The ECM (Z132) has a simple on/off input regarding
activate the Fuel Shut-Off Solenoid (K111). the theft alarm. The ECM (Z132) will not allow the
engine to start once activated and will kill the engine
if activated up to 300 RPM (programmable). Over
Injection Timing (Solenoid Valve Injection Timing 300 RPM, the engine is unaffected.
Device (K229))
This is another actuator within the injection pump.
The ECM (Z132) receives a signal from the needle Relays
lift sensor and attempts to correct the injection timing The DOE engine management system on the diesel
accordingly. If a change does not occur, then the vehicles uses four relays:
ECM (Z132) assumes a fault exists, activates the
ECM (Z132) power supply (main relay), glow plug
warning lamp and reduces the quantity of injected
relay, starter motor relay and fuel pump relay. Two
fuel.
are located in the fuse box and two in the ECM
(Z132) box behind the battery.
Fuel Shut-Off Solenoid (K111)
The Fuel Shut-Off Solenoid (K111) shuts the engine
down if the ECM (Z132) detects a major fault.
Failure of the valve itself does not activate the
warning lamp, although if a short circuit occurs, the
engine will shut down.

Cruise Control
Due to the DOE system being 'drive by wire', a
cruise control feature is supplied in the ECM (Z132)
itself. Activation is via the steering wheel switches to
a converter box and on a single line to the ECM
(Z132). Failure of the signal results in cruise control
not working.

Brake Switches
The ECM (Z132) has two brake inputs, each of
opposite polarity. Comparison of the polarity states
provides the ECM (Z132) with a brake sense (i.e. if
switch 1 high and switch 2 low going to switch 1 low
and switch 2 high) and so cancels cruise control. If
both switches are the same polarity, the ECM (Z132)
senses a fault and does not allow cruise control.

Vehicle Speed Signal

The ECM (Z132) takes this signal from the
Anti-Lock Brake System ECU (Z108) and uses the
information for cruise control and 'active surge
damping'. Failure of the signal results in cruise
disallowed and temporary lack of surge damping (i.e.
hard acceleration will cause the vehicle to surge
slightly). After 10 sec. a substitute value of 150 km/h

CIRCUIT OPERATION •
ED _D_IE_S_E_L _

Main Relay
Located in the ECM (Z132) box, this relay supplies
the power feed to the ECM (Z132). It is controlled via
the Ignition Switch (X274) in position II.

Glow Plug Relay (Z135)

The Glow Plug Relay (Z135) takes a feed directly
from the battery and, on initialisation via the ECM
(Z132), supplies current to each of the six glow plugs
(one per cylinder) to aid cold starting. The glow time
is controlled via the ECM (Z132) which also monitors
the relay and illuminates the glow plug indicator lamp
for the duration of the glow time. This relay is
relatively large and is located with the main relay
next to the ECM (Z132).

Starter Motor Relay

This relay is also ignition key controlled, activated
with the key in the ignition III position only. Releasing
the key after cranking cuts supply to the relay and
switches off the starter motor.

Fuel Pump Relay

The fuel pump relay is pulled in when the starter
motor is activated, the earth path provided by the
alternator output. When the engine is running, the
starter motor is deactivated, supplying an earth path
while the generator supplies a feed i.e. a polarity
reversal.

ECM (Z132)
If the ECM (Z132) itself is not working, the entire
engine management system will cease to operate,
i.e. no fuel, tacho reading, etc.

CIRCUIT OPERATION

Starting System
When the Ignition Switch (X274) is switched to
position III, the BeCM (Z238) grounds the starter
solenoid relay inside the Engine Compartment Fuse
Box (P125) which then energizes, applying battery
voltage to the Starter Solenoid (K136) and Starter
(M134).

Charging System
When the Ignition Switch (X274) is in position II, the
BeCM (Z238) turns the charge warning light on via
the datalink connection to the Instrument Pack
(Z142)
When the Generator (Z1 06) starts to produce power,
the BeCM (Z238) gets an input signal on Pin 15 and
turns off the charge warning light.
For the Diesel engine this signal is also used as an
input signal for the fuel pump relay inside the Engine
Compartment Fusebox (P125) to make sure that the
Fuel Pump (M109) is only supplied with power when
the engine is running.
If the Generator (Z1 06) fails to produce power, the
charge warning light remains illuminated.

• The brake pedal is depressed. With the brake
pedal depressed, the Brake Switch Vent Valve
(X112) moves to position 1 and the circuit is in-
terrupted.
• The transfer gear box is not in Hi range.
• The vehicle speed does not exceed 28 mph (45
km/h).
• The vehicle is not in a forward gear (P, R, or N)
(Automatic Transmission).
• The clutch pedal is depressed (Manual Trans-

• The engine rpm rises above 5000 ± 10% (Ma-
nual Transmission).
The BeCM (Z238), which monitors these signals, will
then remove power from C255/Pin 18.

Diesel Engine
For vehicles equipped with a manual transmission,
cruise control can only be activated when the Cruise
Control Switch (X115) is depressed and the clutch
pedal is not depressed. The Diesel Engine Control
Module (Z132) will not allow the engine to overs peed
if a cruise control speed is requested that is beyond
the capability of the engines speed range.
For vehicles equipped with an automatic

depressed under these conditions, the
Inverter/Converter (Z249) is suppplied with a ground
signal. This signal is transmitted via the OY wire to
the Engine Control Module (ECM) (Z132) causing
the vehicle to accelerate. When the SET/ACCEL
Switch is released, the signal is removed signalling
the Engine Control Module (ECM) (Z132) to set the
speed.

RES
When the RES Switch is depressed, a signal is
applied to the ECM (Z132) and the vehicle will return
to the previously set speed.

Speed Input
The BeCM (Z238) receives the vehicle speed signal
from the Anti-lock Brake System ECU (Z108). The
BeCM (Z238) then provides the vehicle speed signal
to the Engine Control Module (ECM) (Z132). This
signal is a pulsing voltage and its frequency changes
with the vehicle speed.

System Disable
The cruise control system can be disabled in two
ways:
1. The Cruise Control Switch (X115) is put in the 0
position, causing the BeCM (Z238) to remove
power from the Engine Control Module (ECM)
(Z132) and erasing the set speed memory.
2. The Voltage applied via the Inverter/Converter
(Z249) to the Engine Control Module (ECM)
(Z132) terminal 20 is interrupted, causing the
Engine Control Module (ECM) (Z132) to disenga-
ge the system. This voltage path is interrupted
when:
• The brake pedal is depressed. The Engine Con-
trol Module (ECM) (Z132) has two Stop Lamp
Switch (X168) inputs, each of opposite polarity.
The ECM (Z132) compares the polarity states to
determine when the brake pedal has been de-

dule (ECM) (Z132) memory.
CAUTION: DO NOT ENGAGE CRUISE CONTROL
WHEN VEHICLE IS BEING USED IN LOW
TRANSFER GEARS.
WARNING: The use of cruise control is not
recommended on winding, snow covered or slippery
roads, or in heavy traffic conditions where constant
speed cannot be maintained.
1. Start the engine and depress the Cruise Control
Switch (X115) to activate the cruise control
system. Accelerate to approximately 30 mph (50
km/h) and press the SET/ACCEL Switch. Imme-
diately release the switch and remove foot from
the accelerator pedal. The vehicle should main-
tain the speed at which the SET/ACCEL Switch
was pressed.
2. Press the SET/ACCEL Switch and hold at that
position. The vehicle should accelerate smoothly
until the switch is released. The vehicle should
now maintain the new speed at which the SETI
ACCEL Switch was released.
3. Press the RES/DECEL Switch while the vehicle
is in the cruise control mode. The cruise control
should disengage. Slow to approximately 35 mph
(55km/h) and press the RES/DECEL Switch.
Immediately release the switch and remove foot
from the accelerator. The vehicle should
smoothly accelerate to the previously set speed.
Increase speed using the accelerator pedal. Re-
leasing the pedal should return the vehicle to the
previously set speed.
4. Depressing the brake pedal should immediately
disengage the cruise control system and return
the vehicle to driver's control at accelerator pe-
dal. Press the RES/DECEL Switch and the vehi-
cle should accelerate to the previously set speed
without operation of the accelerator pedal.
5. Press the RES/DECEL Switch and allow the ve-
hicle to decelerate to below 26 mph (42 km/h).
Press the RES/DECEL Switch and remove foot
from the accelerator pedal. The vehicle should
smoothly adjust to the previously memorized
speed.
6. Press the SET/ACCEL Switch below 28 mph
(45km/h) and the cruise control system should
remain disengaged. Accelerate the vehicle abo-
ve 28 mph (45 km/h), press the RES/DECEL
Switch and remove foot from the accelerator pe-
dal. The vehicle should smoothly adjust to the
previously memorized speed.
7. Pressing the Cruise Control Switch (X115)
should immediately disengage the cruise control

2. If the cruise control system does not operate cor-

rectly and the vehicle is equipped with a Diesel
TROUBLESHOOTING HINTS Engine, do Test E.
8. If the interior lights operate but the cruise control
switch light does not illuminate, check the bulb, B
wire and RW wire. If the cruise control system
operates but the cruise control switch light does
not illuminate, check bulb and OW wire.
9. Inspect vacuum hoses for kinks and restrictions.
10. Inspect actuator linkage for restrictions and ad-
justment.
11. Check the following two input signals to the
BeCM (Z238): Signal from Clutch Pedal Position
Switch (X200) for vehicles equipped with a ma-
nual transmission, or the X, Y, and Z switch sig-
nals from the Gearbox Position Switch (X294) for
vehicles equipped with an automatic transmis-
sion.
12. For vehicles equipped with a Petrol Engine,
check the following input signal to the BeCM
(Z238): Transfer box in Hi range signal from
Transfer Gear Box ECU (Z256).
13. For vehicles equipped with a Diesel engine,
check the Stop Lamp Switch (X168) inputs to the
Engine Control Module (ECM) (Z132).
14. Note: For vehicles equipped with a manual trans-
mission, cruise control can only be activated
when the Cruise Control Switch (X115) is de-
pressed, the transfer gear box is in Hi range (Pe-
trol only), and the clutch pedal is not depressed.
Also, the BeCM (Z238) will deactivate cruise
control if the engine rpm rises above 5000 +/- 10
percent, due to the possibility of selecting ma-
nual without the use of the clutch (Petrol only).
For vehicles equipped with an automatic trans-
mission, cruise control can only be activated
when the Cruise Control Switch (X115) is de-
pressed, the transfer gear box is in Hi range (Pe-
trol only), and the transmission is in one of the
forward gears. The Transfer Gear Box ECU
(Z256) provides the BeCM (Z238) with transfer
gear box Hi range status. The Transfer Gear Box
Position Switch (X294) provides the BeCM
(Z238) with X, Y, Z switch status (PRND321 po-
sition information).

the gearbox and the transfer box then, after a five
second safety delay, the transfer box moves to
neutral and the lights on both side of the "H" are
extinguished.

Interface to Auto Gear Box Control Unit (Z255)

- pin 35
The High/Low signal to the Auto Gear Box Control
Unit (Z255) comes from the High range status lamp.
If the Auto Gear Box Control Unit (Z255) does not
receive the range information, then an incorrect gear
change mode could be selected, i.e. Manual rather
than Sport in High range and vice versa in Low
range. Also, the shift strategy is different between
the Economy modes of High and Low and so poor
shift quality could result.

Automatic Selector Park Interlock

When the gear selector lever is in the park position,
the shift interlock solenoid is deenergized and
prevents the selector from being moved to another
gear. To free the selector, the Ignition Switch (X134)
must be in position II and the brake pedal must be
depressed.

Interface to Petrol Engine Control Module (ECM)

(Z132)
The Auto Gear Box Control Unit (Z255) takes the
engine torque, engine speed and throttle angle
signals from the ECM, calculates which gear is
required, outputs to the solenoid valves and sends a
torque reduction signal back to the ECM, thereby
retarding the ignition point on each of the cylinders
and so giving a reduction in engine power during
gear changes that result in a smooth change.
The engine torque is received by the Auto Gear Box
Control Unit (Z255) on its pin 21, the engine speed
on pin 3 and the throttle angle on pin 47. The torque
reduction signal is sent to the ECM from the Auto
Gear Box Control Unit (Z255) via its pin 32.

Interface to Diesel Engine Control Module (ECM)

(Z132)
The functionality of the interface is similar to the
petrol interface, except for the format of the signal.

The gear position switch is mounted on the side of
the gearbox and contains five internal switches,
although only 3 are connected to the Auto Gear Box
Control Unit (Z255)via pins 50, 14, and 33. By
analysing the status of these 3 switches, the Auto
Gear Box Control Unit (Z255) calculates which gear

a screen over the cable attached to pin 20. It is
important that this signal is screened correctly.

wheel. The fault code can be retrieved using a diagnostic
tester.
Anti-Lock Brake System ECU (Z108)
The Anti-Lock Brake System ECU (Z108) is a
computer that controls ABS system operation by
consistently monitoring the vehicle's 4 wheel speeds
when the ignition is in position II. If an impending
wheel lock up is detected during this monitoring, the
Anti-Lock Brake ECU (Z108) will apply voltage to
the various inlet and outlet valve solenoids contained
in the ABS Booster Unit (Z103). Operation of the
solenoid valves regulates the pressure applied to
each wheel brake calliper and therefore prevents
wheel lock-up.
Electronic Traction Control (ETC) is an extension to
the Anti-Lock Brake System ECU. In addition to
monitoring the rear wheel speeds for lockup, the
Anti-Lock Brake System ECU also monitors wheel
speed for traction control. When rear wheel slip is
detected (one wheel spinning faster than the other),
the Anti-Lock System ECU will apply the brake to
the spinning wheel, causing additional torque to be
applied to the non-spinning wheel.
The Anti-Lock Brake System ECU applies the brake
by operating various inlet and outlet solenoid valves
in the ABS Booster.
The ETC warning light will be on for up to 60
seconds while the system is active, and the
message TRACTION is displayed. After 60 seconds
of ETC operation, the ETC warning light will begin to
flash to inform the driver that the system has been
shut down to allow the brakes to cool. Also the
message TRACTION OVERHEAT is displayed.
If the ETC warning light stays on continuously for
more than 60 seconds, a fault in the system is
indicated. The message TRACTION FAILURE is
also displayed.
The Anti-Lock Brake System ECU (Z108) also has
diagnostic capabilities that allow it to detect faults
that may impair the system's efficiency. If a fault

The 2 isolation valves consist of 2 solenoid valves
that control fluid inlet and outlet. Their function is to
disconnect or isolate the master cylinder from the
servo cylinder and to connect the servo cylinder to
the reservoir return during ABS functions.

Wheel Speed Sensors (X137, X140, X158, X161)

A wheel speed sensor is located at each wheel. The
speed sensors generate an AC voltage signal as a
toothed ring rotates past the stationary sensor
pickup. The Anti-Lock Brake System ECU (Z108)
calculates the wheel speed by measuring the
frequency of the AC voltage signal generated by the
sensors.

ABS Hydraulic Pump (M102)

The hydraulic boost for the system is provided by the
ABS Hydraulic Pump (M102), which is controlled by
the ABS Pump Relay (K1 02) and the ABS Pressure
Switch Unit (Z104).
The Pressure Switch unit incorporates three
electro- mechanical switches. The first operates the
pump, two more illuminate the low pressure
condition and signal that ABS and ETC functions
should be curtailed. The Hydraulic Pump includes a
hydraulic accumulator and non-return valve, as well
as a pressure relief valve to protect the system.
When low pressure occurs in the brake system, a
switch in the pressure switch unit closes to ground
the coil of the pump relay. The pump relay now
energizes and applies battery voltage from the fuse
to the hydraulic pump through the closed relay
contacts. The hydraulic pump runs to increase
pressure in the hydraulic accumulator. When
sufficient pressure is developed in the system, the
pressure switch opens to de-energize the pump
relay and to turn off the hydraulic pump.

Audible Warning
CIRCUIT OPERATION
Receipt of an audible warning request signal from a
vehicle parameter/message condition shall cause the
Engine Coolant Temperature Gauge BeCM (Z238) to generate the required number of
warning tones. The actuator sounder unit is located
The engine coolant temperature gauge sensor has

the capability to sense from -40°C to +130°C. Petrol
and Diesel resistance valves are different. See message listing for categories/priority and levels
of audible warnings.
Both Petrol and Diesel sensors are interfaced to the
Instrument Cluster (Z142) via the BeCM (Z238). The
resistance value then being represented by an AID
data transfer generating the required angular
deflection on this gauge. [AID = Analog to Digital]

Fuel Gauge
When the fuel tank level is low ("E"), the resistance
value of the gauge sensor is 27011 for petrol and
diesel engines. As the fuel level increases, the
resistance of the sensor decreases. When the fuel
tank is full, the resistance value of the sensor for
petrol engines is 1911 and for diesel engines 25.811 .
When the fuel gauge sensors resistance value
increases to 17511 (9 liters/2.25 US gallons, the low
fuel warning light will illuminate to warn of the fuel
status. Both Petrol and Diesel sensors are interfaced
to the Instrument Cluster (Z142) via the BeCM
(Z238). The resistance values then being
represented by an AID data transfer generating the
required angular deflection on the gauge.

Speedometer
The signal to activate the gauge is originated at the
ABS wheel sensors, transmitted to the ABS ECU
(Z1 08) which then puts out a usable signal to the
Instrument Cluster (Z142) of 8000 pulses per mile or
4972 pulses per kilometer. The signal is also
transmitted to other ECU's, such as the Engine
Control Module (ECM) (Z132) and the Cruise Control
ECU (Z121).

Tachometer
The tachometer will display the engine speed in
RPM. It will derive the engine speed from the
engine speed pulse train transmitted from the Engine
Control Module (ECM) (Z132).
The pulse rate for petrol engines will be 4 pulses per
engine revolution.
The pulse rate for diesel engines will be 3 pulses per
engine revolution.

buttons illuminate. On some models, when the park tweeter incorporates a capacitor to filter the signals.
lamps or headlamps are turned on, a voltage signal
is sent through the RW wire to dim the LCD display
and control buttons for night driving.
Radio (Z111) signals are received via a coaxial cable
from the side screens and antenna amplifiers. The
amplifiers filter and boost the signal from the side
screen, using power supplied on WO wires,
whenever the Ignition Switch (X274) is in position I
or II.
The CD Changer (Z114) is permanently supplied
with power through the P wire via the radio and a
DIN cable.
For the new Range Rover, three levels of
factory-fitted in-car entertainment are available.
The mid/low line radio has the following features:
Electronically tuned AM/FM cassette radio (Z111),
RH antenna amplifier (Z178) for AM/FM signals and
6, 8 or 10 speakers.
The high line (NAS/JAPAN) radio has the following
features: Electronically tuned AM/FM cassette radio
(Z111), RH antenna amplifier (Z178) for AM/FM
signals, LH antenna amplifier (Z177) for FM signals
only, 4 door speaker amplifiers (Z241 , Z242, Z245,
Z246), a subwoofer amplifier (Z176), a CD changer
(Z114) and 10 speakers plus a subwoofer speaker
(K146).

Subwoofer
The subwoofer amplifies frequencies between 20
and 150 Hz to give an enhanced bass sound.

Subwoofer Amplifier
The Subwoofer (K146) is supplied with power and
ground from the Subwoofer Amplifier (Z176) via two
separate channels which consist of 4 BW/B wires.
The subwoofer amplifier (Z176) is permanently

CIRCUIT OPERATION •

Side Screen Antenna

The antenna is printed into the rear side screen. For
NAS and Japan, the element is fitted in both rear
side screens. This is referred to as a diversity
antenna system. Other markets have a single
element in the right hand screen only. Diversity
reception means that as vehicle movement results in
loss of signal due to reflections from buildings
(known as multipath distortion), the radio will switch
to the antenna receiving the strongest signal. This
results in less interference and better stereo
performance.

Antenna Amplifier
Antenna amplifiers are in the LH and RH side of the
luggage compartment behind trim panel.The FM and
AM amplifier would be located on the right hand
side, and the FM only amplifier is located on the left
hand side.

Speakers
Trim level 1/2 - The low/midline radio is equipped
with 6, 8 or 10 speakers fitted in the doors. The
midrange speakers (K200, K201, K211, K212) are
filtered by capacitors in the wires (K239, K240,
K247, K248) and the tweeter speakers (K197, K198)
filter the signals by built-in capacitors.
Trim level 3 - the high line is equipped with 10
speakers like the trim level 1/2, but they all receive
power and ground via 4 additional speaker
amplifiers. The signals for the tweeter speakers
(K197, K198) are filtered by their internal capacitors,
similar to the mid/low line tweeters.

 HEATED FRONT SCREEN 1m
CIRCUIT OPERATION

This operates only with the engine running, which is

determined by the HEVAC panel. In the off state, the
signal is at 12 volts. When the Heated Front
Windscreen is activated, the signal is switched to 0
volts. This provides the ground required for relay 5 to
be pulled in, as there is an ignition feed on the other
side of the coil provided by relay 15. This relay
energises one half of the heated screen elements.
Once relay 5 has been energised, a 12 volt signal is
provided to the coil of relay 4. The other side of the
coil is connected directly to ground, thereby
energising the relay and switching on the other half
of the elements.
There is also a feed spliced from the harness which
provides the petrol Engine Control Module with a
signal that tells the unit there will be a large electrical
load turned on/off.

CIRCUIT OPERATION

Side lamps:
Activation of the side lamp switch, when the ignition
key is in, when the ignition is on, or when the head
lamp switch is on, will result in the operation of the
following; front LH and RH side lamps, rear LH and
RH side lamps, number plate lamps, lamps on warn-
ing lamp and the rear door switch pack illumination.
The following lamps will also operate through the
activation of the side lamp switch:
Clock, fascia switch pack, console switch pack, gear
select assembly, instrument pack, front cigar lighter,
Hevac panel switches and I.C.E. (remote telephone
dial, when fitted).

Parking lamps:
With the ignition and auxiliary off, the key out and the
headlamp switch in the side lamp position, the park-
ing lamps will be activated according to the position
of the direction indicator switch as follows:
• If the indicator switch is in the central position,
then all the side lamps will be on.
• If the indicator switch is in the RH position, then
the front right and rear right side lamps will be
on.
• If the indicator switch is in the LH position, then
the front left and rear left side lamps will be on.
If the headlamp switch is set to the headlamp posi-
tion, then normal side lamps will operate in conjunc-
tion with the headlamps.

Side lamp Warning lamps:

The side lamp warning lamp will be active whenever
the side lamp switch is on and the side lamps are
operating in side lamp mode, but not when the key is
removed and the parking lamp mode is on.

illumination bulb will operate at the specified rate,
regardless of the ignition switch position. The indica-
tor warning lamps within the instrument pack will
also operate under this condition.
If the inertia switch is operated and the ignition is on,
all indicator bulbs, side repeaters, warning lamps
and the hazard switch bulb will flash at the specified
rate.
In addition to the operation of the indicator bulbs
there will be an audible tick generated by the SeCM,

CIRCUIT OPERATION

Front Fog lamps

With the ignition switch and side lamp or headlamp
switch on, a momentary operation of the front fog
lamp switch will activate the front fog lamps. A fur-
ther momentary operation of the fog lamp switch, or
switching off of the headlamps/side lamps or ignition,
will cause the front fog lamps to be extinguished.
N.B. The front fog lamps will always be inactive
when the ignition is turned on.

Rear Fog lamps

With the ignition on, the headlamp switch on or front
fog lamps on, a momentary operation of the rear fog
lamp switch will activate the rear fog lamps. Opera-
tion of the rear fog lamps will also activate a bulb
within the fog lamp switch. A further momentary op-
eration of the fog lamp switch, switching off the head
lamps and front fog lamps, or switching off the igni-
tion, will cause the rear fog lamps to switch off. N.B.
The rear fog lamps will always be inactive when the
ignition is turned on.

• rear left courtesy lamp
• rear right courtesy lamp
• load space lamps
• front left footwell lamp
• front right footwell lamp
• ignition ring illumination
• rear right footwell lamp
• rear left footwell lamp
If any door is left open, the lamps will fade out after a
time of approximately 10 minutes. During the 10
minute time out, if any other door is opened the timer
will be reset.
If all doors are closed prior to the end of this 10
minute period then all specified lamps will fade out
after a delay of 15 seconds.
If the ignition is switched on before the end of the 15
second time out period, the specified lamps will
begin to fade out after a delay of 1 second.
If the ignition is then switched off and no door
opened, the 15 second time out of the lamps will not
be resumed.
If an unlock signal is received from the remote key,
or if a key unlock is received from either of the front
doors while all the doors are closed, then the
courtesy lamps will fade to on in 0.5 seconds and
begin a 15 second time out period.
If any of the doors or the tailgate are opened during
this delay, then the time out period will be restarted.
If all the doors are closed and a lock signal is
received from the remote key or either of the front
door COL switches while the courtesy lamps are in
their 15 second time out period, then the time delay
will be cancelled and the lamps immediately faded
out.

Panel Dimmer:
Operation of the panel dimmer switch, with the side
lamps on, will alter the level of panel illumination be-
tween approximately 6 and 94%. Depressing the
switch momentarily will cause the illumination to in-
crease or decrease to the next level. Holding the
switch closed will cause the illumination to ramp to-
wards fully on or fully off.
The illumination level selected will be stored in the
SeCM's non-volatile memory whenever the driver's
seat store sequence is completed successfully, pro-
vided the side lamp switch is on. If the side lamp
switch is not on and a successful memory store se-
quence is completed, then the previously stored illu-
mination level will remain unchanged.

Puddle lamps
With any door open and the automatic courtesy lamp
feature enabled, the puddle lamp within the relevant
door will be illuminated, either until the door is closed
or a time period of approximately 10 minutes has
elapsed. If any puddle lamp is on, momentary
operation of the courtesy lamp master switch will
extinguish all puddle lamps on release of the switch.
Further operation of the switch or reopening a door
(if automatic courtesy lamps are enabled) will again
activate the puddle lamps for those doors that are
open. If the courtesy lamp switch is held on for
longer than 2 seconds, the automatic operation of
the puddle lamps from the door open switches will
switch between enabled and disabled.

CIRCUIT OPERATION
Ignition position 1 (Accessories)
This feed is obtained from the BeCM via fuse 8 and
is shared with the Radio, Front cigar lighter, Aerial
amplifier and car phone (if fitted). The Ignition 1 is
essential to the control panel as it provides power to
the ECU although no functions or display on the LCD
are possible.
Ignition position 2
This feed is obtained from the BeCM via fuse 17.
Battery feed
This feed is obtained from the fuse box via fuse 42.
Ground Connection
This feed runs down to a spliced joint, joining the
main earth run down to fascia earth point 1.
Dimmer Line
This Pulse Width Modulated signal is provided by the
BeCM.
LCD Dimmer line
This line is a input to the HEVAC and the signal is a
inverse Pulse Width Modulated signal which is
determined by the instrument pack.
Alternator Charge signal
This signal is given to the HEVAC ECU to inform it
that the engine is running. This signal is active low.
Diagnostic Kline
This line is used to communicate with the diagnostic
equipment (TESTBOOK) and is normally held at 12V
when not active
Left/Right Recirculation motors
These motors control the flaps on the blower motor
modules. The flaps should be in one of two
positions, either fully open or fully closed.
Left/Right Blower modules
The blowers have a permanent 12V feed to them.
The speed of the motors is determined by the control
lines which go to the motors. The motors also
provide a voltage feedback to the HEVAC ECU to
determine the actual voltage at the motors but also
to show if there are any faults.
Left/Right Blend and Distribution Motors
These motors are controlled by the HEVAC ECU
which provides power to the motors, which in turn
report back their actual positions to the HEVAC
ECU.

inverse Pulse Width Modulated signal which is
determined by the instrument pack.
Compressor Clutch
The clutch line provides a 12 volt power feed to the
compressor clutch via pressure switch 1.
Condenser Fans
The HEVAC panel provides a signal normally at 12
volts for "off" condition and 0 volts for the "on"
condition, which in the case of petrol vehicles is fed
into the ECM and diesel vehicles directly onto the
coil of relay 18. In line is the Air-Conditioning
pressure switch 2, which turns the fans on/off.
When relay 18 is energised, it provides connection
between relays 13 and 14 (fan 1 and 2) in series or
parallel with each other. This is dependent upon the
state of the air-conditioning pressure switch 1.
For the petrol option, when the signal enters the
ECM, the ECM will switch the output on/off to the
fuse box. The ECM will switch the output on
sometimes for engine cooling reasons even though
the engine has been turned off.
Aspirator
There are two parts of this sensor, one of which is a
fan which draws cabin air onto the temperature
sensor. The temperature sensor then sends the
signal back to the HEVAC ECU.

131 HEATING AND VENTILATION (WITH Ale)

AlC Request
This signal is active low and sends a request to the
ECM to switch on the air-conditioning system.
AlC Grant
This signal is active low and sends a signal to the
HEVAC ECU to acknowledge the request signal and
that it is ready for the load to be switched on by the
HEVAC system.
Pressure switch 1 (Trinary switch)
This switch is in parallel with two components, the
condensor fans and the compressor clutch which are
both normally short circuit. If the pressure is too high
or too low, the switch will open and cut the feed to
the clutch to prevent damage to the system. With the
third setting, at a specific pressure the switch is
shorted and changes the condenser fan mode from
series to parallel.
Pressure switch 2 (Single switch)
The switch is normally open circuit. At a specific
pressure, the switch is shorted and allows the
condenser fans to turn on.
Left/Right Recirculation motors
These motors control the flaps on the blower motor
modules. The flaps should be in one of two
positions, either fully open or fully closed.
Left/Right Blower modules
The blowers have a permanent 12V feed to them.
The speed of the motors is determined by the control
lines which go to the motors. The motors also
provide a voltage feedback to the HEVAC ECU to
determine the actual voltage at the motors but also
to show if there are any faults.
Left/Right Blend and Distribution Motors
These motors are controlled by the HEVAC ECU
which provides power to the motors, which in turn
report back their actual positions to the HEVAC
ECU.

There will be trap detection on sunroof close and on

If a trap is detected whilst the sunroof is closing from
the slide position, then the sunroof will back off 20cm

the sunroof is closing from the tilt position then the
sunroof will back off to the fully tilt open position.
These conditions will also activate a message on the
instrument pack which will be accompanied by three
audible beeps.
With the sunroof in the closed or partially tilted open
position, operation of the sunroof forward switch will
cause the roof to operate in the tilt open direction.
This will continue until the switch is released, or until
a stall condition is detected.
If the sunroof back switch is operated while the
sunroof is in the tilt open position, the roof will
operate in the tilt close direction. This will continue
until the switch is released, a trap is detected or until
the sunroof is in the closed position.
If the sunroof back switch is operated with the
sunroof in the closed or partially open position, the
sunroof will operate in the open direction. This
movement will continue until the switch is released
(unless in the one touch mode), the sunroof forward
switch is operated, or a stall condition is detected.
With the sunroof in an open position, operation of the
sunroof forward switch will cause the sunroof to
operate in the close direction. This will continue until

 HEATED SEATS em
CIRCUIT OPERATION
Driver and passenger seat heaters are PTC
regulated. Heated seat activation requests and
timing functions are generated by the Hevac ECU
while the Ignition Switch (X274) is in position II. The
SeCM (Z238) provides power switching only for this
function. In the case of both rear windows and the
sunroof being operated at the same time or an
uninitialised rear window or sunroof function being
operated, the seat heaters will be inhibited to
maintain current demand within a safe operating
area.
The signals are sent from the HEVAC ECU to the
SeCM (Z238) and are active low. Therefore the lines
are normally held at 12V.

• CIRCUIT DIAGRAM
 MEMORY MIRRORS _

Vehicles fitted with automatic transmission will have

a 0.5 sec delay following the selection of reverse
CIRCUIT OPERATION gear prior to the mirror dip position being recalled.

General
The following combinations of seat and mirror
adjustment method will be available:
11. Memory driver's seat, memory passenger seat
and memory mirrors.
12. Memory driver's seat, electric passenger's seat
and memory mirrors.
13. Mechanically adjusted driver's and passenger's
seats, electric mirrors.
The memory mirror system will store the horizontal
and vertical position of each mirror. Storage and
recall functions will be controlled by the driver's
memory seat control switches, each seat memory
position having a mirror memory position associated
with it.
Memory mirror enable and one touch enable will
occur under the same conditions as memory seat
enable and one touch enable.

Reverse dip position

Reverse mirror dipping will be enabled when the
presence of a driver's side seat memory outstation is
detected.
If a driver's seat memory store sequence is executed
whilst auxiliary is selected and the transmission is in
reverse, then the stored mirror position will be the
position that the mirrors will dip to when reverse gear
is next selected and that memory number is
currently recalled. To protect against accidental
setting, the mirror position will only be stored if it has
been altered since reverse was selected and a
message on the instrument pack will inform the
driver that the mirror position has been stored.
The function may be toggled on and off by holding
the memory store button for at least 2 seconds whilst
in reverse gear with auxiliary or ignition selected.
Successful toggling of the function will be
accompanied by the message "Mirror dip on"I"Mirror
dip off" as described in the message parameter
table.
Successful toggling of the function will result in the
mirrors moving immediately to the dipped/undipped
position as appropriate.
Storing a new reverse dip position will automatically
toggle the function on.

 TRAILER AUXILIARY SOCKET III
CIRCUIT OPERATION
Accommodation within the system has been made
for the addition of a trailer lighting system to consist
of 2 side lamps, 2 fog lamps, 2 reverse lamps, 2
brake lamps, 1 LH indicator and 1 RH indicator.
In addition to these loads, there is also a provision
for a 10 amp battery feed to the trailer.

Bulb Failure Diagnosis With Trailer

The diagnosis of external bulb failures will be
modified by the presence of a trailer as follows:
Brake lamps
• Diagnosis of the RH vehicle and trailer lamps will
only detect a failure of all the filaments.
• Diagnosis of the LH vehicle brake light is unaf-
fected.
Rear side lamps
• Diagnosis of the LH rear side lamps will only de-
tect the failure of both the vehicle filament and
the trailer filament.
• Diagnosis of the RH rear side lamps will only de-
tect the failure of both the vehicle filament and
the trailer filament.
Reverse lamps
• Diagnosis of the RH vehicle reverse light and the
LH and RH trailer reverse lamps will only detect
failure of all of the filaments.
• Diagnosis of the LH vehicle reverse light is unaf-
fected.
Fog lamps
• Diagnosis of the RH vehicle rear fog light and the
LH and RH trailer fog lamps will only detect failu-
re of all of the filaments.
• Diagnosis of the LH vehicle rear fog light is unaf-
fected.

CIRCUIT OPERATION •
III TRAILER AUXILIARY SOCKET

Direction indicators
The indicator warning lamp and trailer warning lamp
will diagnose the status of the vehicle's rear
filaments, and trailer direction indicator filaments
according to the following table:

Indicator wll Trailer wll Vehicle filament Trailer filament

Flash Flash Good Good
Flash Extinguished Good Faillnot fitted
Flash Flash Fail Good
Flash wi double rate Extinguished Fail Faillnot fitted

In the case of hazard light operation with trailer

lamps fitted, the failure of a trailer direction indicator
light will cause the trailer warning light to flash at
double rate, while the direction indicator light will
flash at the "standard" rate.

air within the air springs located next to each wheel.
It should be noted that the system is not intended to
control the roll or dive of the vehicle whilst cornering
or braking. The accuracy of height control achieved
is sufficient to ensure that no additional driver
controlled means of adjusting the headlamp beam is
required to compensate for different vehicle loading
conditions.
The system can operate in anyone of five heights or
modes: Access, Low Profile, Standard Profile, High
Profile and Extended Profile. All heights with the
exception of Extended Profile can be selected by the
driver using the ride height switches on the fascia.
When Inhibit is selected (indicated by the Inhibit
switch tell-tale lamp being illuminated), automatic
height changes between Standard and Low Profile
are disabled; it is recommended that Standard
Profile Inhibit mode is selected whenever a trailer is
being towed.
The ride height of the vehicle is displayed to the
driver by the LEOs in the ride height display adjacent
to the ride height switches on the fascia. The LED
for the current ride height is continuously illuminated
whenever the engine is running. When a height
change is taking place, the LED for the new target
height flashes and the LED for the old height
remains continuously illuminated until the new target
height is reached whereupon the old height LED is
extinguished and the new height LED is continuously
illuminated.
It should be noted that if any of the side doors or the
tailgate are open when the vehicle speed is less than
5 mph (8 km/h), all height changes are suspended
until the doors and tailgate are closed. If a door has
been open for more than 30 seconds, then the
system will need "reminding" of the new height after
the door has been closed. This condition is indicated
by the LEOs for the old and new heights both being
continously illuminated.
Application of the footbrake also causes any height
changes to be suspended whilst it is pressed. If the
footbrake has been applied continously for more
than 3 minutes, then height changes are allowed to
resume.
The ride height of the vehicle is correctly maintained
only whilst the engine is running. To compensate for
any changes in load after parking (e.g. driver or
passengers getting out),the EAS system will lower

buttons.

Basic Overview - Alarm

All new Range Rovers are equipped with a
sophisticated intergrated security system.
The alarm system offers the following forms of
protection:
• Perimetric protection against unauthorised ope-
ning of any of the hinged "slam" panels.
• Engine crank inhibit against unauthorised engine
crank.
• Electronic engine immobilisation against unau-
thorised engine start.
• Volumetric protection against intrusion into the
passenger compartment.

Basic Overview - Lazy Locking

An additional feature of the new Range Rover's
security system is Lazy Locking.
Lazy Locking enables the driver to close any open
glass panel (window or sunroof) from outside the car
using either the key or the remote handset.
Lazy Locking can be carried out either when locking
or super locking the vehicle, or when the vehicle is
already in a locked state.
N.B. Activation of a lazy locking sequence will be
dependent on market requirements.

In this state the alarm remains inactive (provides no

Sill locking can be achieved independently of key-in
and ignition switch status.
• Slam Locking:
Depressing either of the front door sill buttons with
either front door open, will result in all the doors and
the tailgate locking and the vehicle entering a slam
locked state.
Following a slam locking operation, the alarm will
enter the perimetric mode, engine crank will be
disabled and electronic engine immobilisation will be
activated.
Attempting to slam lock the vehicle with either the
key in the ignition, or the ignition on, will cause
unlocking of all the doors.
• Key Locking
A single turn of the key towards the front of the
vehicle will result in all the doors and tailgate locking.

ton on the remote handset has been released.
• In dead man's handle mode, closure of the win-
dows and sunroof will only continue for as long
as the key is held to the lock position, or the lock
button is pressed on the remote handset. In this
case, failure of any of the apertures to be fully
closed upon release of the key/button will result
in a mislock.

Mislock
A mislock condition is indicated by either two short
"beeps" from the alarm sounder, or by three short
flashes of the courtesy lights, depending on the
market legislation.

Partial Arming Of The Perimetric Alarm

If the perimetric alarm is armed with one (or more) of
the doors, or the tailgate, or the bonnet open, then
the remaining panels are all protected by the alarm.
If any of the open panels are subsequently closed,
then they too will be protected by the alarm.
Security LED
The security LED has two functions:
• Firstly for the initial ten seconds after a lock re-
quest, it provides visual confirmation of the lock
status.
• Secondly, after this confirmation period, it acts as
a deterrent to any theft attempt, (flashing at a
slower rate).
Volumetric Protection
Volumetric protection, (protection of the vehicle's
interior), is provided by an Ultrasonic Sensor and
an Ultrasonic detector.
If the vehicle has been successfully superlocked with
the key, then provided all the windows are closed, a

Engine Immobilisation (Diesel)

The electronic engine immobilisation feature fitted to
the diesel engine derivatives is different to the
system fitted to the petrol versions.
The engine immobilisation output will be low if the
alarm is set. If a crank signal is detected with the
alarm set (armed), the "Engine Immobilised"
message sequence will be transmitted to the
instrument pack.
Alarm Triggering
The perimetric alarm will be triggered by any of the
doors opening, the tailgate opening, the bonnet
opening, the ignition key being inserted, the ignition
being turned on, or the inertia switch being tripped.
The volumetric alarm will be triggered by any
movement within the passenger compartment.
The alarm will be triggered a maximum of three
times during any set/unset period. Any further
triggers after this will be ignored.
AudibleNisual Warnings
A disc horn, mounted under bonnet, is used as the
alarm sounder. The output from the sounder is either
pulsed or a continuous tone, depending on market
legislation. If the output is pulsed, then its status will
be synchronised with that of the visual indicators.
The lamps used for external visual indication are
dependent upon market legislation, but will be either
Hazards, or Side and Tail, or Dip and Tail.
