INTRODUCTION Battery Voltage Before commencing diagnosis of electrical problems verify the condition of the battery is acceptable by using the open circuit voltage test. Open circuit voltage test 1. Switch off all electrical loads on the vehicle. 2. Adjust digital multimeter to read de volts on the appropriate scale. 3. Connect test probes across battery terminals ensuring that polarity is correct and record the voltage displayed . A reading of 12.3V or more is acceptable; any battery which reads less than this will need charging.
I\
NOTE: If the vehicle has been used within a period of 8 hours prior L..J to the test, surface charge must be removed from the battery by switching the headlamps on for approximately 30 seconds. Wait a further 60 seconds before checking the open circuit voltage. Battery voltage is used as a known reference for ascertaining whether or not circuits are receiving sufficiently high voltage for components to function correctly. This reference is only a guide since most electronic circuits are designed to function over a wide range of voltages . In addition , consideration must be given to readings affected by voltage drop across certain components and fluctuations due to cable lengths.

INTRODUCTION ELECTRICAL PRECAUTIONS General The following guidelines are intended to ensure the safety of the operator whilst preventing damage to the electrical and electronic components fitted to the vehicle . Where necessary, specific precautions are detailed in the relevant sections of this document, reference to which should be made prior to commencing repair operations . Equipment- Prior to commencing any test procedure on the vehicle ensure that the relevant test equipment is working correctly and any harness or connectors are in good condition. This particularly applies to mains lead and connections .
WARNING: Before commencing work on an ignition system all high tension terminals, adapters and diagnostic equipment for testing should be inspected to ensure that they are adequately insulated and shielded to prevent accidental personal contact and to minimize the risk of shock. Wearers of surgically implanted pacemaker devices should not work in close proximity to ignition circuits or diagnostic equipment.
A
Polarity- Never reverse connect the vehicle battery and always observe the correct polarity when connecting test equipment. High Voltage Circuits- Whenever disconnecting live ht circuits always use insulated pliers and never allow the open end of the ht lead to come into contact with other components particularly ECUs. Since high voltage spikes can occur on the terminals of the coil while the engine is running, exercise caution when measuring the voltage at these points.
DEFENDER V8i
1.3
INTRODUCTION Connectors and Harness- The engine compartment of a vehicle is a particularly hostile environment for electrical components and connectors. Always ensure these items are dry and oil free before disconnecting and connecting test equipment. Never force connectors apart either by using tools or by pulling on the wiring harness. Always ensure locking tabs are disengaged before removal and note orientation to enable correct reconnection . Ensure that any protective covers and substances are replaced if disturbed. Before removing a faulty component, refer to the Workshop Manual for removal procedures. Ensure the starter switch is turned to the "OFF" position, the battery is disconnected (see Battery disconnecting) and any disconnected harnesses are supported to avoid any undue strain at terminals . When replacing the component keep oily hands away from electrical connection areas and push connectors home until any locking tabs fully engage.
Battery disconnecting Before disconnecting the battery, switch off all electrical equipment. If the radio is to be serviced, ensure the security code has been deactivated. CAUTION: To prevent damage to electrical components ALWAYS disconnect the battery when working on the vehicle electrical system. The earth lead must be disconnected first and reconnected last. Always ensure that battery leads are routed correctly and are not close to any potential chafing points.
&
Battery charging Recharge the battery out of the vehicle and keep the top well ventilated. While being charged or discharged, and for approximately fifteen minutes afterwards, batteries emit hydrogen gas. This gas is inflammable. Always ensure any battery charging area is well ventilated and that every precautions is taken to avoid naked flames and sparks.

INTRODUCTION Disciplines Switch off ignition prior to making any connection or disconnection in the system as electrical surge caused by disconnecting 'live' connections can damage electronic components. Ensure hands and work surfaces are clean and free of grease, swarf, etc. as grease collects dirt which can cause tracking or high-resistance contacts. When handling printed circuit boards, treat them as you would a brake dischold by the edges only; note that some electronic components are susceptible to body static. Connectors should never be subjected to forced removal or refit, especially inter-board connectors, damaged contacts will cause short-circuit and opencircuit conditions . Prior to commencing test, and periodically during test, touch a good earth, i.e. cigar lighter socket, to discharge body static as some electronic components are vulnerable to static electricity.
Grease for electrical connectors All under bonnet and under body connectors are protected against corrosion by the application of a special grease on production. Should connectors be disturbed in service or repaired or replaced, a grease of this type , available under Part No. BAU 5811 , should again be applied .
6
NOTE: The use of other greases must be avoided as they can migrate into relays, switches etc. contaminating the contacts and leading to intermittent operation or failure.

INTRODUCTION Fault diagnosis When diagnosing an electrical fault follow the steps below: 1. Read the circuit description and study the circuit diagram appropriate to the reported fault to ensure a good understanding of circuit operation. 2. Study the power distribution, fuse details and earth distribution diagrams and identify other circuits which share fuses and/or earth points. Check whether these circuits operate correctly. 3. Using the photographs contained in the Connector section , locate a point on the circuit (approximately half way between supply and earth) which is easily accessible. 4. Check that the pin out details of the connector are correct and that the correct signals exist at the correct terminals. 5. Using the marker pen supplied (or other suitable non-permanent marker pen), mark the parts of the circuit you have verified . 6. Continue to the next point on the circuit which is easiest to access and repeat the above. 7. Continue this approach until a fault is found, rectify the fault and then verify that the circuit operates correctly.

DESCRIPTION AND OPERATION ENGINE IMMOBILISATION DESCRIPTION The engine immobilisation system fitted to the Defender 50LE works in conjunction with the alarm system . The Alarm ECU sends a coded signal to the Engine Control Module (ECM) . If the signal does not match the one expected by the ECM, the ECM will immobilise the engine. Passive immobilisation is also fitted, with a passive coil fitted around the ignition barrel. This will activate 30 seconds after the ignition is turned off and the drivers door is opened. Alternatively, passive immobilisation will occur 5 minutes after the vehicle is unlocked, or the ignition is turned off. When attempting to restart the vehicle, passive immobilisation can be switched off using either the RF handset or EKA code .
OPERATION Feed from the positive battery terminal is supplied to fusible link 5 in the engine compartment fuse box (C1217-1) on a brown wire. Fusible link 5 (C570-2) then supplies a feed to the ignition switch (C28-1) on a brown wire, and fuse 3 of the passenger compartment fuse box (C580-3), also on a brown wire. The ignition switch a fuse 3 are connected in parallel. Fuse 3 of the passenger compartment fuse box (C580-6) supplies a constant battery input to the Alarm ECU (C61-25) on a purple wire. The Alarm ECU (C57-11) is earthed on a black wire. When the ignition switch is turned to position 'II', a feed is supplied to both fuse 1 (C580-1) and fuse 17 (C581-13) of the passenger compartment fuse box. These two fuses are connected in parallel via white wires . Fuse 17 (C581-14) supplies an ignition feed to the Alarm ECU (C61-10) on a green wire .
DEFENDER V8i
4.1
DESCRIPTION AND OPERATION Fuse 1 (C580-2) is connected to the engine lmmobilisation warning lamp (C1192-1) by a white/green wire. The lamp is controlled by the Alarm ECU. The warning lamp (C1193-1) is connected to the ECU (C61-11) by a red/slate wire . To illuminate the lamp, the ECU provides an earth. To extinguish the lamp, the ECU provides a feed equal to that provided by fuse 1, creating a 0 volts potential difference. In this way, the ECU can control the flashing sequence of the lamp. When an ignition feed is received by the Alarm ECU (C61-1 0), it sends a coded signal (C61-15) to the ECM (C636-26) on a black wire. If the signal does not match the one expected by the ECM, the ECM will immobilise the engine. The Alarm ECU (C57) is also connected to the starter inhibitor/reverse light switch (C69-4) by a black/orange wire . The Alarm ECU can be interrogated via the diagnostic socket using TestBook. The socket (C40-8) is connected to the ECU (C61-17) by an orange/light green wire . In addition to the features directly controlled by the Alarm ECU , a passive coil is fitted around the ignition barrel. This is a user friendly way of re-mobilising the engine. The passive coil (C672-1) receives a power supply from the Alarm ECU (C57-7) on an orange/green wire. The passive coil is only energised when the ignition switch is in position 'II' and the engine is in an immobilised state. The coil creates a magnetic field that excites a coil in the RF handset. This causes the handset to transmit a code to the Alarm ECU to re-mobilise the engine.
4.2
DEFENDER V8i
DESCRIPTION AND OPERATION ANTI-THEFT ALARM DESCRIPTION Although a key is used in the normal way to lock and unlock the vehicle, this will not fully arm the alarm system. The system is fully armed with an RF handset, which transmits a rolling code. This code is received by the alarm ECU. If a door is opened without the alarm ECU receiving the correct signal from the handset, the alarm will sound . The Alarm ECU also immobilises the engine, failing to provide a feed to the starter relay, immobilising the engine. See Engine lmmobilisation. OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. Fusible link 5 (C570-2) provides a feed to the following; • The ignition switch (C28-1) on a brown wire. • Fuse 2 (C580-3) of the passenger compartment fuse box on a brown wire . • Fuse 3 (C580-3) of the passenger compartment fuse box on a brown wire . Fuse 2 and 3 are connected in parallel. Fuse 3 (C580-6) supplies a constant battery feed to the Alarm ECU (C61-25) on a purple wire. The Alarm ECU is supplied a permanent earth (C57-11) by a black wire. The alarm ECU (C57-8) also receives a constant battery feed from fuse 2 (C580-4) on a purple wire. This feed is then used to power the hazard warning lamps (C57-1 & C57-6) on green/white and green/red wires . When alarm is armed , the Alarm ECU receives a number of inputs. The RH door switch (C265-1) is connected to the Alarm ECU (C61-16) by a purple/blue wire . When the door is closed, the switch is open. In this condition , the Alarm ECU (C57-5) supplies the BBUS (C666-3) with battery voltage. When the door is opened, the door switch closes, providing a short to earth. The Alarm ECU responds by supplying the BBUS with a reduced voltage . Sensing this drop in voltage, the BBUS sounds.
DEFENDER V8i
4.3
DESCRIPTION AND OPERATION The same principle is true of the LH door switch, the tail door switch, and the bonnet switch . The LH door switch (C106-1) is connected to the Alarm ECU (C61-5) by a slate/white wire. The tail door switch (C615-1) is connected to the Alarm ECU (C61-16) in parallel with the RH door switch on a purple/blue wire. The bonnet switch (C?-2) is connected to the Alarm ECU (C61-9) on a orange/blue wire, and is provided an earth (C?-1) on a black wire . All 3 switches interact with the BBUS in exactly the same way as the RH door switch. In addition to being supplied with a constant battery feed (C666-2) from fuse 2 (C580-6) of the passenger compartment fuse box, the BBUS also has its own internal power supply, and is earthed (C666-4) on a black wire. The Alarm ECU (C61-20) also provides a feed for the ultrasonic sensor (C359-1) on a black/brown wire . The sensor is earthed (C359-2) on a black wire . When the module detects movement within the vehicle, it supplies the Alarm ECU (C61-3) with a short series of pulses on a white/black wire. Once the Alarm ECU detects these pulses, the BBUS is sounded. To disarm the alarm system, the RF handset is used. The signal transmitted by the handset is received by the aerial. The aerial is connected to the Alarm ECU (C61-26) by an orange/slate wire.
4.4
DEFENDER V8i
DESCRIPTION AND OPERATION The anti-theft alarm LED is used as a visual deterrent, and is connected to the Alarm ECU (C57-4) by a pink wire. To illuminate the LED, the Alarm ECU provides a path to earth (C57-11) on a black wire. To extinguish the LED, the Alarm ECU provides it (C240-1) with a voltage equal to that provided by fuse 3 of the passenger compartment fuse box. As the potential difference across the LED is now 0 volts, the LED is extinguished . In this way the Alarm ECU can control the flashing sequence of the LED . The Alarm ECU also controls the interior lamps. The ECU (C61-1) provides a feed to the both the front (C355-1) and rear (C356-1) interior lamps on purple/white wires . An earth is provided for both lamps on black wires. The alarm system can be interrogated through the diagnostic socket (C40-8), which is connected to the Alarm ECU (C61-17) by an orange/light green wire.

DESCRIPTION AND OPERATION STARTING AND CHARGING DESCRIPTION The charging system consists of a generator containing a rectifier pack and regulator to maintain a constant direct (de) voltage in the system. The generator is belt driven from the crankshaft and is cooled by a fan mounted behind the pulley. The generator has a fixed coil wound stator in which a field coil rotor rotates. Slip rings conduct current to and from the field coils via 2 carbon brushes. The regulator senses output voltage and controls this to approximately 14 volts. CHARGING- OPERATION Feed from the positive battery terminal is connected to fusible link 5 (C1217-1) of the engine compartment fuse box by a brown wire. Current flows from fusible link 5 (C570-2) to the ignition switch, also on a brown wire. With the ignition switch in position 'II', current flows to fuse 1 (C580-1) of the passenger compartment fuse box on a white wire . Fuse 1 (C580-2) supplies a feed to the ignition/no charge warning lamp (C233-2) on a white/green wire . The warning lamp (C233-5) is earthed via a diode and generator field windings (C185-1) on a brown/yellow wire . The flow of current through the warning lamp and field windings partially magnetises the rotor. A resistor is wired in parallel with the warning lamp to ensure continued exciter voltage in the event of a bulb failure. When the engine starts, the magnetised rotor rotates within the stator windings, generating a 3 phase alternating current (ac) and voltage which rises rapidly with rotor speed. The field diodes convert the ac current to direct current (de) and the generated voltage is fed back to the field windings. As the feed back voltage increases, the magnetic influence of the rotor also increases, resulting in self excitation of the rotor. Generated current and voltage increases with rotor speed until the generator is fully excited . When the generator outputs a voltage equal to that supplied by the battery, the warning lamp is extinguished as the potential difference across the lamp is 0 volts. The diode between the generator and warning lamp prevents reverse flow.
4.6
DEFENDER V8i
DESCRIPTION AND OPERATION The regulator functions as an electronic control switch on the earth side of the field coils. The regulator rapidly switches the earth circuit off and on to control the generated voltage and current to safe limits. If the battery is in a low state of charge or current draw from the electrical system is high and causes a voltage drop, the generator charges at its maximum rate until 14 volts is generated . As battery voltage rises, the generator current output voltage reduces .
STARTING- OPERATION With the ignition switch in position 'II ', current flows to fuse 20 (C581-13) of the passenger compartment fuse box on a white wire. Fuse 20 (C581-20) is connected to the fuel pump relay coil (C157-2) in the engine management relay module by a white/green wire. The fuel pump relay coil (C157-1) is earthed through the ECM (C634-24) on a blue/purple wire. The ECM earths the fuel pump relay for a short period of time when the ignition switch is in position 'II', and continuously during cranking and while the engine is running. With the fuel pump relay energised , current from fuse 6 (C574-2) of the engine compartment fuse box can flow across the relay (C154-7 & C154-4) to the inertia switch (C123-3) on a white/purple wire . Assuming the inertia switch is closed, current flows across the switch (C123-1) to the fuel pump (C113-4) on a white/purple wire. The fuel pump is earthed (C113-3) on a black wire. When the ignition switch is turned to the 'crank' position , current flows across the switch (C94-1) to the starter relay coil (C151-85) on a white/red wire. The relay coil (C151-86) is connected in series to the inhibitor switch (C69-5) by a black/yellow wire . Assuming the gear selector lever is in the 'Park' or 'Neutral ' position , a route to earth is provided from the inhibitor switch (C69-4) to the Alarm ECU (C57-10) on a black/orange wire .

DESCRIPTION AND OPERATION If the engine has been re-mobilised, the Alarm ECU will provide an earth (C57-11) for the starter relay on a black wire. Now the starter relay has been energised , a battery feed from fusible link 5 (C570-2) on a brown wire will flow across the relay (C151-87 & C151-30) to the starter motor (C179-1) on a brown/red wire. This feed will energise the starter motor solenoid, allowing a battery feed to flow across the solenoid switch and power the motor. An earth is provided by the starter motor casing .

DESCRIPTION AND OPERATION GENERIC ENGINE MANAGEMENT SYSTEM (GEMS) DESCRIPTION GEMS is the engine management system utilised by Defender V8i models, controlling both the electronic ignition and fuel injection systems. It is able to alter ignition and fuelling settings to ensure the engine is operating at its optimum performance for the prevailing conditions. The ECM receives signals from sensors located around the engine and uses the data to control the fuel quantity, fuel injection timing and ignition timing in order to achieve optimum combustion of the fuel mixture in each cylinder. The main features of the system are as follows: • A single engine control module (ECM) controls the fuel injection system and ignition system. The ECM incorporates short circuit protection and can store intermittent faults on certain inputs. TestBook can be used to interrogate the ECM for the stored fault codes . • Fuel is injected sequentially. That is, when the relevant piston is on the inlet stroke and the intake valve is open. • The ECM is electronically coded and prevents the engine being started unless it receives the correct code from the Alarm ECU. • Detection and correction of engine knock on individual cylinders. The ignition timing of each cylinder can be varied independently to the other cylinders and ensures that knock on one cylinder is eliminated without a detrimental effect on the ignition timing of the other cylinders. • A diagnostic connector, located below the passenger compartment fuse box, allows engine tuning or fault diagnosis to be carried out using TestBook. • If certain inputs to the ECM fail, a back-up facility enables the engine to continue running, although at a reduced level of performance.

DESCRIPTION AND OPERATION IGNITION SYSTEM The ignition system utilises a direct ignition system (DIS) negating the need for a distributor. The system comprises 4 double ended coils operating the wasted spark principle. The circuit to each coil is controlled by the ECM. When a coil fires, a spark is produced in two cylinders , however, as the resistance is higher in the cylinder on the compression stroke, more spark energy is dissipated in this cylinder.
The ECM determines the optimum ignition timing based on signals from the following sensors: • Crankshaft position (CKP) sensor- engine speed and crankshaft position • Camshaft position (CMP) sensor- camshaft position • Intake air temperature (IAT) sensor- inlet air temperature • Knock sensors- engine vibration, detonation The engine management system uses no centrifugal or vacuum advance, timing is controlled entirely by the ECM.
Crankshaft position (CKP) sensor The CKP sensor signal is used as the basis for ignition timing. It informs the ECM that the engine is turning, the speed the engine is turning and position of the engine in its cycle. The sensor uses the principle of magnetic induction to generate the signal. A reluctor ring , attached to the engine flywheel, has a series of teeth spaced at 1oointervals, with one tooth missing at 20° after TDC . The reluctor ring rotates with the flywheel, in close proximity to the CKP sensor. As each tooth of the reluctor ring passes the sensor, it disturbs the magnetic field of the sensor and a voltage is induced in the sensor coil. The ECM calculates engine speed by counting pulses per second from the CKP sensor. Engine position is calculated by counting pulses after the missing pulse.

DEFENDER V8i
DESCRIPTION AND OPERATION Camshaft position (CMP) sensor The CMP sensor is used in conjunction with the CKP sensor to inform the ECM of the position of the engine in the 4 stroke cycle . Using the CKP sensor alone, the ECM is unable to determine whether a cylinder is on its compression stroke or exhaust stroke. The sensor uses the principle of magnetic induction to generate the signal. The cam wheel has four gaps, one smaller than the others, which pass in close proximity to the CMP sensor as the camshaft rotates. The lobes disturb the magnetic field of the sensor and induce a voltage in the sensor coil. In the event of a sensor failure, the ECM will continue to operate normal ignition timing and sequential fuel injection using the CKP sensor signal. The sequential fuel injection may be 180째 out of phase . Engine knock detection and correction will be disabled.
Inlet air temperature (IAT} sensor The basis of the IAT sensor is a temperature dependent resistive metal strip. The resistance of the metal strip varies considerably with temperature. When an inlet temperature of 55째C or higher is detected, the ECM retards the ignition timing . If the sensor fails, the ECM assumes an inlet temperature or 50째C. Knock sensor The knock sensor is a piezo-electronic accelerometer, which produces an electronic signal related to the vibration of the engine. A knock sensor is located in each bank of cylinders. The signal from each knock sensor is transmitted to the ECM. The ECM is able to filter out normal engine vibrations and detect vibrations induced by engine knock.
DEFENDER V8i
4.11
DESCRIPTION AND OPERATION Using the signal from the knock sensor in conjunction with the CKP and CMP signals enables the ECM to identify which cylinder is producing the knock and hence retard the ignition timing of that cylinder only. The ignition timing of the cylinder producing the knock is retarded until the knock disappears. The ECM then advances the ignition timing to find the optimum advance angle for that cylinder. The ECM is able to perform a similar function for each of the 8 cylinders simultaneously. It is therefore possible for all 8 cylinders to have different advance angles at any one time . FUELLING SYSTEM Engine fuelling is by a fully sequential, electronic fuel injection system, controlled by the ECM. The ECM determines the timing and quantity of fuel to be injected based on information received from the following sensors. • Crankshaft position (CKP) sensor- engine speed and crankshaft position • Camshaft position (CMP) sensor- camshaft position • Mass air flow (MAF) sensor- quantity of air entering the engine • Throttle position (TP) sensor- position of throttle and rate of change of throttle • Engine coolant temperature (ECT) sensor- engine coolant temperature • Fuel temperature sensor- temperature of fuel rail • Heated oxygen sensor (H02S) -oxygen content of exhaust
Crankshaft position (CKP) sensor The CKP sensor signal is used as the basis for fuel injection timing. It informs the GEMS that the engine is turning , the speed the engine is turning and position of the engine in the cycle. The sensor uses the principle of magnetic induction to generate the signal. A reluctor ring , attached to the engine flywheel, has a series of teeth spaced at 1oointervals, with one tooth missing at 20° after TDC . The reluctor ring rotates with the engine, in close proximity to the CKP sensor. As each tooth of the reluctor ring passes the sensor, it disturbs the magnetic field of the sensor and a voltage is induced in the sensor coil. The ECM calculates engine speed by counting pulses per second from the CKP sensor. Engine position is calculated by counting pulses after the missing pulse.

DESCRIPTION AND OPERATION Camshaft position (CMP) sensor The CMP sensor is used in conjunction with the CKP sensor to inform the ECM of the position of the engine in the 4 stroke cycle . Using the CKP sensor alone, the ECM is unable to determine whether a cylinder is on its compression or exhaust stroke. The sensor uses the principle of magnetic induction to generate the signal. The cam wheel has four lobes which pass in close proximity to the CMP sensor as the camshaft rotates . The lobes disturb the magnetic field of the sensor and induce a voltage in the sensor coil. In the event of a sensor failure, the ECM will continue to operate sequential fuel injection using the CKP sensor signal. It is possible that the injection timing will be one engine revolution out of sequence.
Mass air flow (MAF) sensor The MAF sensor is used to measure the quantity of air being drawn into the engine and hence give an indication of the quantity of fuel to be injected to provide a stoichiometric mixture strength. The MAF sensor is an anemometer located in the inlet air flow and consisting of two wires, one heated and one not. The non heated wire is at ambient temperature and has a resistance which is used as a reference . The heated wire is maintained at a constant temperature difference above the non heated wire . As air flows over the heated wire, current is applied to the wire to maintain the temperature difference, the faster the air flow, the greater the cooling effect and the greater the current required to maintain the temperature difference. The current supplied to the hot wire is converted to a voltage signal and sent to the ECM. The ECM uses the voltage signal to calculate the quantity of air being drawn into the engine. If the sensor fails, the ECM calculates a value dependent on throttle position, engine speed and air temperature.
DEFENDER V8i
4.13
DESCRIPTION AND OPERATION Throttle position (TP) sensor The TP sensor measures the angle of throttle opening and the rate of change of throttle position. The angle of throttle opening gives an indication of the quantity of air being drawn into the engine. The rate of change of throttle angle gives an indication of rate of acceleration demanded. The sensor is a rotary variable resistor mounted to the throttle butterfly spindle giving an output of 0 to 5 volts.
Engine coolant temperature (ECT) sensor The coolant temperature sensor measures the temperature of the engine coolant. The signal from the coolant sensor is used by the ECM to adjust the fuelling mixture. The engine requires a richer mixture at lower temperatures. The sensor relies on a temperature dependent resistive metal strip. The resistance of the metal strip varies considerably with temperature and is immersed in the engine coolant. If the sensor fails, the ECM assumes an engine coolant figure of 80째C. The fault could be noticable during the engine warm up period .
Fuel temperature sensor The fuel temperature sensor measures the temperature of the fuel rail. The signal from the sensor gives the ECM a warning of fuel vapourisation and the possibility of bubbles forming in the injectors. If the ECM receives a high fuel temperature signal during starting, the fuel injector opening period is increased to clear any vapourisation bubbles from the injectors and correct the fuelling. When the engine is running, fuel circulation from the fuel tank keeps the fuel rail cool and flushes away any bubbles.

DESCRIPTION AND OPERATION Heated oxygen sensor (H02S) 2 H02S's are fitted to the vehicle, 1 before each catalyst. A H02S comprises a titanium metal sensor surrounded by a gas permeable ceramic coating . Oxygen permeating the ceramic coating reacts with the titanium wire, altering its resistance . The resistance of the sensor is directly related to the quantity of oxygen around the sensor. The H02S does not function correctly until it reaches a temperature of approximately 300째C and so a heating element is incorporated into the sensor to provide rapid warm up after a cold start. The signals from the H02S's are used by the ECM to correct the fuelling to each bank of cylinders independently. The 2 sensors measure the oxygen content of the gasses exhausted from the engine, indicating a rich or weak mixture strength. The ECM alters the pulse width of the injectors to correct the mixture strength and achieve a stoichiometric air/fuel ratio.
Injectors The fuel injection system has 8 fuel injectors, 1 for each cylinder. Each injector comprises a solenoid with a needle valve held in position by a spring. The route to ground for the solenoid is controlled by the ECM . When energised , the solenoid lifts the needle valve from its seat and pressurised fuel from the fuel rail flows through the injector. The injector orifice is shaped to produce a fine spray of fuel which aids combustion.
DEFENDER V8i
4.15
DESCRIPTION AND OPERATION Fuel pressure regulator The fuel pressure regulator is a mechanical device mounted to the fuel rail. Its purpose is to control the fuel rail pressure with respect to the inlet manifold depression. The fuel rail pressure must be reduced at high manifold depressions to avoid excess fuel being drawn through the injector nozzles. The fuel regulator contains a spring loaded diaphragm valve with pressurised fuel on one side of the diaphragm and manifold vacuum acting on the other. When fuel rail pressure, assisted by manifold depression, overcomes the diaphragm spring load , fuel flows past the diaphragm valve to the fuel tank, reducing fuel rail pressure. With manifold depression low, during hard acceleration, the fuel rail pressure must be high to overcome the diaphragm spring load . With manifold depression low, during coast down, the vacuum acting on the diaphragm valve acts against the spring load and a lower fuel rail pressure lifts the valve from its seat.
Idle air control valve (IACV) Engine idle speed is maintained by the IACV, connected to the stepper motor and controlled by the ECM. With the throttle butterfly fully closed, a small quantity of air is able to by-pass the throttle butterfly via the base idle passage . The ECM monitors engine speed and load via sensors around the engine. Should extra air be required to maintain a steady idle speed, the ECM signals the stepper motor to operate a number of steps and open the IACV to allow air through the throttle by-pass. The stepper motor operates over a range of 180 steps with the IACV fully open at 0 steps and fully closed at 180 steps.

DESCRIPTION AND OPERATION Purge valve The vehicle is equipped with an evaporative emission control system designed to prevent vapour loss from the fuel tank. Fuel tank vapour is passed through a charcoal canister which traps fuel vapour. The vapours trapped by the charcoal canister is drawn in to the engine through the purge valve and burnt in the combustion chamber. The ECM controls the opening of the purge valve to allow venting of the charcoal canister. The ECM pulses the purge valve open for short periods when the engine has reached normal operating temperature and is turning at a speed over 1700 rpm. This is done to ensure that the fuelling of the engine is not adversely affected during warm up or at idle. During purge valve operation, the ECM monitors H02S signals. If opening the purge valve causes the H02S signal to indicate a leaner mixture, the ECM assumes that the charcoal canister is empty. When the charcoal canister is monitored to be empty, the purge valve is opened to prevent a build up of fuel vapour in the canister. With the purge valve open, unmetered air is drawn into the engine through the charcoal canister. The ECM uses the signal from the H02S's to corrects the fuelling .
Inertia switch Power to the fuel pump is supplied via the inertia switch. In the event of extreme deceleration, as would be experienced in a collision , the inertia switch trips, isolating electrical supply from the fuel pump. The switch is reset by pressing the rubber button on top of the switch.

DESCRIPTION AND OPERATION DIAGNOSTIC SOCKET DESCRIPTION The diagnostic socket is located below the passenger compartment fuse box. The connector is constructed to ISO standard and allows the attachment of TestBook or any other ISO standard scantool. The diagnostic socket allows diagnostic information stored in any of the vehicle's ECU's to be retrieved. It also allows engine tuning and fault diagnosis to be carried out via the engine control module (ECM). OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. A constant battery feed is provided to the diagnostic socket (C40-16) by fuse 4 (C573-1) of the engine compartment fuse box on a purple wire . An earth is provided for the socket (C40-4) on a black w1re . To allow TestBook to interact with the Alarm ECU, the diagnostic socket (C40-8) is connected to the ECU (C61-17) by an orange/light green wire. To interact with the ECM, 2 pins are set aside (C40-7 & C40-15). The ECM is connected to the diagnostic socket by white/pink (C636-20) and white/light green wires (C636-23).

DESCRIPTION AND OPERATION AIR CONDITIONING DESCRIPTION The air conditioning (A/C) system fitted to the Defender 50LE operates independently of the standard heating and ventilation system. Controlled by 2 switches mounted in the centre of the fascia, the A/C system will only operate when the engine is running and the blower control is in at least position 1. The blower control is a 3 position switch, and works in conjunction with the temperature control. Temperature control is by a variable resistor. The cooled and dehumidified air produced by the A/C system is directed through vents located in the lower fascia bezel. The A/C system can be used in conjunction with the standard heating and ventilation system. By combining the two separate systems, virtually any required interior condition can be met. OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. Current flows across fusible link 1 and fusible link 2, which are connected in series. From fusible link 2 (C570-1 ), current flows to fuse 15 and 16 (C581-5) of the passenger compartment fuse box on a brown/purple wire . Fuses 15 and 16 are connected in parallel. Fuse 15 (C581-10) supplies a feed to the blower relay switch (C817-30) on a brown/slate then purple/slate wire. Fuse 16 (C581-12) supplies a feed to both the condenser fan relay switch (C1212-30) on a brown/white wire , and the compressor clutch relay switch (C1213-30), also on a brown/white wire . When the ignition switch is turned to position 'II', current is allowed to flow from the ignition switch (C90-1) to fuse 17 (C581-13) of the engine compartment fuse box on a white wire .

DESCRIPTION AND OPERATION Fuse 17 (C581-14) supplies a feed to the blower relay coil (C817-86) on a green wire, and the compressor clutch relay coil (C1213-86), also on a green wire . The blower relay coil (C817-85) is earthed on a black wire. The earth path for the compressor clutch relay coil (C1213-85) is controlled by the ECM (C634-1), which is connected to the relay by a blue/black then black/slate wire . The now energised blower relay (C817-87) allows current to flow to the blower motor switch (C275-5) on a brown wire. The blower motor switch is a 3 position switch. Slow speed is attained by turning the switch to position 1. A feed can now flow from the switch (C275-3) to the blower motor (C848-1) on a blue wire. As the current has to flow through the 2 in-line resistors before reaching the motor itself, a slow motor speed is attained. The motor is earthed (C1215-1) on a black wire. Turning the blower switch to position 2 allows a feed to flow from the switch (C275-1) to the blower motor (C844-1) on a green wire . As the current now only has to flow through 1 in-line resistor, a medium speed is attained. For high speed operation, turning the blower switch to position 3 (C275-2) allows current to flow direct to the motor (C845-1) on a red wire without having to flow through the in-line resistors . As in the case of low speed and medium speed operation, the blower motor (C1215-1) is earthed on a black wire . Once the blower motor switch has been turned to position 1, it also allows current to flow (C275-4) to the interlock relay coil (C153-4) on a blue/yellow wire . The relay coil is earthed (C153-2) on a black wire . The interlock relay is also energised when the blower switch is in position 2 and 3. Although the blower will operate with the ignition on, the air conditioning system itself will not operate until the engine is running, and a number of conditions are met.

DESCRIPTION AND OPERATION Fuse 7 of the engine compartment fuse box (C574-1) supplies a feed to the main relay coil within the engine management relay module (C154-6) on a brown/light green wire. If the engine is running, the ECM (C635-17) provides an earth path for the main relay (C157-3) on a blue/red wire. This energises the main relay and allows a feed (C154-3) to flow to the condenser fan relay coil (C1212-85) on a brown/orange then slate/blue wire . The earth path for the condenser fan relay (C1212-86) is again controlled by the ECM (C634-3), this time on a slate/black then green/white wire. This energises the condenser fan relay, and allows the feed from fuse 16 of the passenger compartment fuse box (C581-12) to flow across the relay (C1212-30 & C1212-87) and onto the condenser fan (C280-1) on a blue/purple wire. The condenser fan is earthed (C280-2) on a black wire . The compressor will only operate if a number of conditions are met, and is controlled by the compressor clutch. The clutch will only allow the compressor to operate if: • The engine is running. • The refrigerant pressure in the high pressure line is within the set limits. • The temperature within the system is within the set limits. • Excessive engine temperatures are not reached. Assuming all these conditions are met, the compressor clutch relay will be energised by the ECM. Current will flow from the relay (C1213-87) to the compressor clutch (C182-1) on a brown/pink wire. The clutch is earthed (C182-2) on a black wire . This engages the compressor clutch and drives the compressor.

DESCRIPTION AND OPERATION HEATER BLOWER DESCRIPTION The heater is operated by three sliding controls attached to the instrument binnacle. Two of the controls regulate the temperature and air flow distribution. The third control operates the two speed heater blower. The heater blower operates with the ignition switch in position 'I', and is completely independent of the air conditioning system. OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. Current passes through fusible link 5 (C570-2), which is connected to the ignition switch (C28-1) by a brown wire . With the ignition switch in position 'I', power flows across the switch (C99-1) to fuse 4 (C580-7) of the passenger compartment fuse box on a white/orange wire . Fuse 4 (C580-8) then supplies a feed to the blower motor (C431-3) on a purple/green wire . When the blower switch is in the 'Off' position, the blower motor has no route to earth and does not run . Moving the blower switch to position '1', connects the blower motor (C431-2) to the blower switch (C58-2) on a green/yellow wire. Power flows through the blower motor and resistor to the switch , which is earthed (C58-3) on a black wire . The blower motor will now operate at low speed. Moving the blower switch to position 'II', connects the blower motor (C431-1) directly to the blower switch (C58-1) on a green/slate wire. Again, the switch is earthed (C58-3) on a black wire. The blower motor now operates at high speed.

DESCRIPTION AND OPERATION HEATED REAR WINDOW (HRW) DESCRIPTION The heated rear window (HRW) is operated by a latching switch mounted on the dash panel. When the switch is set to the 'On' position, the instrument panel warning lamp will illuminate to indicate the HRW is operating. The HRW only operates when the ignition switch is turned to position 'II'. OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. Current passes through fusible link 1 and fusible link 5, which are connected in parallel. Fusible link 5 (C570-2) is connected to the ignition switch (C28-1) by a brown wire. Fusible link 1 is connected in series with fuse 3. Fuse 3 (C571-1) supplies a feed to the heated rear window relay switch (C44-87) on a brown/slate wire . With the ignition switch in position 'II', current flows from the switch (C90-1) to fuse 1 of the passenger compartment fuse box (C580-1) on a white wire. Fuse 1 (C580-2) is connected to the heated rear window switch (C72-4) by a white/green wire. When the switch is depressed, current is allowed to flow across the switch (C72-2) and energise the heated rear window relay (C44-85 & C44-86) on a white/green wire. The relay is earthed on a black wire. The energised relay (C44-30) now allows current to flow to both the heated rear window (C381-1) and the instrument pack warning lamp (C1051-1).

DESCRIPTION AND OPERATION WIPERS AND WASHERS DESCRIPTION The front windscreen wipers are controlled from the column switch and operate when the ignition switch is in position 'II '. The wipers have 2 speed settings, along with a flick wipe and single wipe facility. An intermittent wipe function and programmed wash wipe facility is controlled by the front wiper delay unit. Moving the wiper switch down from the off position initiates the intermittent wipe function . Moving the wiper switch up one position from the off position, operates the wipers at slow speed . Moving the wiper switch up two positions from the off position, operates the wipers at fast speed. Pushing the wiper switch up from the off position, not allowing it to latch, and then releasing it causes the wipers to perform a single wipe cycle at slow speed. Pushing and holding the wiper switch up from the off position, not allowing it to latch, causes the wipers to operate at slow speed until the wiper switch is released. Pressing the end of the wiper switch, initiates the programmed wash wipe sequence . The windscreen washers operate while the switch is pressed and the wipers continue to operate for a number of cycles after the switch is released. The rear screen wiper and wash facilities are controlled by a switch mounted on the dash panel. Pressing the switch causes the rear washer to operate until the switch is released. The rear wiper does not operate automatically with the rear wiper. Turning the switch clockwise causes the rear wiper to operate until the switch is turned back to the off position.

DESCRIPTION AND OPERATION OPERATION Feed from the positive battery terminal is connected to the engine compartment fuse box (C1217-1) by a brown wire. Current passes though fusible link 5 (C570-2) which is connected to the ignition switch (C28-1) by a brown wire . With the ignition switch in position 'II' (C90-1 ), a feed is supplied to fuse 17 and 18 of the passenger compartment fuse box (C581-13) on a white wire. Fuse 17 (C581-14) supplies power to the rear wash/wipe circuit, while fuse 18 (C581-16) supplies power to the front wash/wipe circuit.
Front Wipers and Washers Fuse 18 of the passenger compartment fuse box (C581-16) supplies the front wiper relay (C39-8) a feed on a green wire when the ignition switch is in position 'II'. Slow and Fast Speeds Fuse 18 also provides a feed to the wash/wipe switch (C278-6) on a green wire . Moving the switch to the slow speed position allows power to flow across the switch (C278-1) to the wiper motor (C30-3) on a blue/light green wire . This feed into the wiper motor also has to travel through an internal resistor. This extra resistance causes the motor to operate at slow speed. The wiper motor is earthed (C30-1) on a black wire. Moving the wiper switch to the fast speed position allows power to flow through the switch (C278-5) to the wiper motor (C30-5) on a red/light green wire. This time the feed from the switch does not have to flow through the internal resistor, causing the motor to operate at fast speed . Again, the motor is earthed (C30-1) on a black wire. Operating the flick wipe function outputs a feed from the wash/wipe switch (C278-5) and onto the wiper motor (C30-5) for as long as the switch is held against spring pressure. The wipers operate at fast speed .

DESCRIPTION AND OPERATION Park Circuit Positioning the wash/wipe switch to the 'off' position cuts power to the wiper motor on the blue/light green or red/light green wire . The park circuit operates to return the wipers to their park position. The park switch (C30-4) is integral to the wiper motor. It receives a feed from fuse 18 of the passenger compartment fuse box (C581-16) on a green wire. The park switch is closed with the wipers in any position other than their park position . With the park switch closed, power flows across the switch (C30-2) to the front wiper relay (C39-5) on a brown/light green wire. The front wiper relay (C39-2) is connected to the wash/wipe switch (C278-4) by a yellow/light green wire. Power flows through the wash/wipe switch (C278-1) to the wiper motor (C30-3) on a blue/light green wire. The wiper motor is earthed (C30-1) on a black wire. The wipers operate until their park position is reached and the park switch opens, cutting the power supply to the wiper motor.
Intermittent Wipe Moving the wash/wipe switch to the intermittent wipe position allows power to flow across the switch (C278-3) to the front wiper relay (C39-1) on a white/green wire. When this signal is received by the relay, it switches the route to earth (C39-4) on and off approximately every 5 seconds on a black wire . An intermittent feed is then supplied from the relay (C39-2) to the wash/wipe switch (C278-4) on a yellow/light green wire. Power flows through the switch (C278-1) and supplies the wiper motor (C30-3) on a blue/light green wire. The wipers operate at slow speed. Programmed Wash/Wipe Depressing the end of the wash/wipe switch operates the programmed wash/wipe function. The washer switch (C278-6) is supplied a feed by fuse 18 of the passenger compartment fuse box (C581-16) on a green wire . When the switch is closed, power flows across the switch (C278-2) to the front wiper relay (C39-6) and the windscreen washer pump (C8-2). Both are supplied a feed on light green/black wires. The washer pump is earthed (C8-1) on a black wire .

DESCRIPTION AND OPERATION When the front wiper relay (C39-6) receives a feed from the wash/wipe switch (C278-2), it outputs a feed (C39-2) back to the wash/wipe switch (C278-4) on a yellow/light green wire. Power flows across the wash/wipe switch (C278-1) and onto the wiper motor (C30-3) , which operates at slow speed. When the washer switch is released, the relay will operate the wipers for a further 3 cycles . Once this has been completed , feed to the wash/wipe switch is cut by the relay and the park circuit is initiated.
Rear Wiper The rear wiper switch (C1197-1) is supplied a feed by fuse 17 of the passenger compartment fuse box (C581-14) on a green wire. When the switch is in the 'on' position (C1194-1 ), power is fed to the rear screen wiper motor (C388-2) on a red/light green then brown/light green wire. The wiper motor is earthed (C388-1) on a black wire .
