Alhambra â&#x20AC;&#x2122;01 The SEAT Alhambra has been subjected to a general re-styling in the areas of bodywork, interior trim, instrument panel and powertrain units. Externally, the most notable changes are in the front and rear zones, continuing the trend set by the Toledo 99, which was later applied to various SEAT models. Safety continues to play an important role in Brand strategy, with the advent of the ESP technology, side airbags and 3-point seat belt anchorage for all seats. Another area drawing close attention, is that of driving comfort which is directly related to safety. Improvements here come with the introduction of features such as, Xenon headlights, parking aid, wipers with rain sensor, anti dazzle mirror and the new instrument panel screen. The majority of the new features can be found on the drivetrain, providing engines with power ratings up to 240 HP, matched to 6 speed manual gearboxes or automatic boxes with either 4 or 5 speeds and a Tiptronic function. Finally, a four wheel drive (4WD) option can also be chosen. Furthermore, the maintenance operations have been reduced since all the mechanical assemblies have extended service intervals.

The central area contains the air conditioning and other controls as well as the radio or the optional navigation system. The controls for the rear electric windows have been transferred to the driver’s door and those for the rear quarterlights to the central console.

Many components have been redesigned in the interior of the vehicle. Those which have undergone the most significant changes are: – The dashpanel. – The seats. – The instrument panel. – The central console. – The door panels. The dashpanel repeats the frontal design trend by transmitting the same robust feeling introduced on the Toledo 99.

The worldwide air pollution due to contamination from vehicle exhausts can now be determined. Legislation has been enacted to force the automobile manufacturers to comply with reductions in noxious gas emissions. In Europe, it is obligatory to comply with the EU III legislation from the year 2000 onwards. Despite the fact that different legislation is in force in several countries, there is a general tendency towards the need to comply with the strict USA legislation (OBD II) for exhaust gas emissions. The severe exhaust emission controls make it necessary that all the components involved in the reduction of noxious gas emissions work perfectly. Incorrect operation or faulty engine management components could lead to a considerable increase in pollution emission. To prevent this, the EOBD system has been introduced on all Alhambra petrol engines. Protected by copyright.

The ME7 Motronic is fitted to all petrol engines, and this system complies with the severe EU IV legislation by respecting the pollution limits shown on the chart for this legislation.

D80-06

DIAGNOSIS / POLLUTION WARNING LIGHT K83 The warning light can be found in the instrument panel and its task is to warn the driver of an engine malfunction, which could lead to an increase in the emission of noxious exhaust gases. The warning light has an auto check function, remaining on for a few seconds when the ignition is switched on. If the warning light comes after starting the engine, this could indicate two different faults: – Blinking light, if the vehicle is driven in this condition, the catalyser could be damaged. To avoid damage, the vehicle should only be driven under low power. – The light remains on; in this case we have an increase in the emission of noxious gases. In both cases, the customer should go to his nearest Dealer.

The warning light is monitored directly by the engine control unit and the faults relating to its operation are registered in the engine fault memory.

1.9 TDi ENGINES The 1.9 TDi engines fitted with pump injectors (PD) belong to the EA188 engine family and are presented with two different power ratings of 66 and 85 kW. Both these engines are turbocharged, and the 85 kW version uses a variable geometry turbo. The main new feature on these engines is the injection system incorporating a pump injector assembly. This technique has already been fitted to the 1.4 TDi engine on the Arosa. The above technology has led to the elimination of the conventional diesel components such as the injection pump and the high pressure injection pipes. The most notable aspects of this new injection system, are the high injection pressure developed and its totally electronic control of both the injected volume and the advance.

CRANKSHAFT PULLEY In order to reduce the load on the crankshaft belt, the crankshaft pulley has two sets of cogs with greater spacing than the remainder. During the injection cycle, the high pressures required to operate the pump injectors place very heavy loads on the belt. The forces required to operate the pump injectors retard the rotation of the belt, while the start of injection forces the crankshaft pulley to increase the speed of rotation. Due to these phenomena, the belt is submitted to a stretching effect, which momentarily increases its tooth spacing. This effect occurs periodically according to the firing order, and the same cogs on the pulley will always be in the driving position. At these two points the spacing between the cogs has been increased, in order to compensate for the stretching of the belt and thus reduce its wear.

EXHAUST GAS RADIATOR

Inlet manifold

On the 85 kW engine, a radiator for the recirculated exhaust gases is bolted to the inlet manifold and its task is to cool the gases passed from the exhaust to the inlet manifold. This radiator uses the engine coolant to reduce the exhaust gas temperature. The reduction in temperature of the exhaust gases means that a greater mass of gas can be passed to the combustion chamber thus reducing NOx emissions.

02N GEARBOX

Transfer case (only on 4WD versions)

The 02N manual gearbox has two notable characteristics, which are its 6 speed configuration and high torque rating (up to 350 Nm.). The gearbox has one mainshaft and two layshafts, thus enabling the overall length to be reduced considerably. This gearbox can be combined with all engines presently available on the Alhambra. The advantage of the 6 speed gearbox is related to the reduction in fuel consumption thus lowering pollution levels and causing less harm to the environment. This gearbox can also be fitted with the 4WD option.

This function is accomplished with the aid of a “u shaped” central tube to which the differential assembly is bolted. A new set of metal/rubber mountings alter the reaction of the axle in relation to that fitted on front wheel (FWD) versions, thus adapting its movements to the specific characteristics of a vehicle fitted with 4WD. Finally, a driveshaft had to be fitted to transmit traction to the rear axle.

The front drivetrain has no major changes although we should point out the new calipers and large dimension disks for the V6 engine model. The rear drivetrain is modified when fitted with the 4WD option.

FOUR WHEEL DRIVE The four wheel drive can only be fitted in combination with the 02N 6 speed gearbox. The rear axle of the Alhambra has been redesigned in order to allow the 4WD option to be fitted. The new axle Subchassis has to retain the longitudinal arms, and at the same time provide a mounting support for the rear differential assembly and the Haldex clutch.

The phase III immobiliser is characterised by use of a variable code for mutual recognition of the engine control unit and the immobiliser control unit. The communication between the immobiliser Emitter and the control unit is through the â&#x20AC;&#x153;Engine Drivetrainâ&#x20AC;? CAN Bus line. In order to simplify the following explanations, we will use these abbreviations: VIN - (Vehicle identification number) Chassis number.

IMMOBILISER MODULE The main new feature on the phase III immobiliser module is its method of communicating with the engine control unit, which is now done using the CAN Bus line. The permanent key codes, the Â¨VINÂ¨ and Â¨SKCâ&#x20AC;? codes are all stored in the module. The modules also have an identification number, enabling their corresponding â&#x20AC;&#x153;PINâ&#x20AC;? to be determined. The module identification number will be altered when it is adapted to a new vehicle using the fault reader.

ENGINE CONTROL UNIT The control unit is an integral part of the immobiliser operating system. The engine control unit memories the â&#x20AC;&#x153;VINâ&#x20AC;?, the immobiliser identification number and its corresponding â&#x20AC;&#x153;PINâ&#x20AC;? and â&#x20AC;&#x153;SKCâ&#x20AC;? codes.

Reader coil

OPERATION The operating procedure of the immobiliser is divided into three parts; the first of these consists in the recognition of the key, which has nothing new in relation to the phase II immobiliser. The second, consisting in the mutual recognition of the immobiliser and engine control units has modifications on this system. The mutual recognition is done by the exchange of variable codes and these will only be recognised when both units already know the â&#x20AC;&#x153;VINâ&#x20AC;? and â&#x20AC;&#x153;SKCâ&#x20AC;? codes.

communication with the instrument panel through the cable “K”. The radiocassette transmits a code which is memorised in the instrument panel. In the event of power supply cut off, when the ignition is switched on again, the radiocassette communicates with the instrument panel, and thus checks to ensure that the same instrument panel was fitted before power cut off. If the check is affirmative, the radiocassette will become operational again within a few seconds, without the need to reintroduce the 4 digit code. However, if the radiocassette is fitted to another vehicle or if the battery was disconnected and the instrument panel replaced, the code will have to be reintroduced.

– When the radio is off, the recording mode can be activated. The maximum duration of the recording function is 24 hours and it will be automatically deactivated when the radio is switched on. – The station has different volume levels depending on the programme content. The radio compensates the basic volume setting by automatic volume adjustment. The stations need to be pre-tuned in order to accomplish this function.

Another new feature which can also be found on the “HIGH” version is the possibility to display indications relating to the navigation system on the central screen of the instrument panel (the navigation system is only available with the “high” version of the instrument panel).

The synoptic chart shows all the components, which make up the navigation system. With regard to the present system, we only need to point out one difference which consists in the elimination of the signal from the ABS wheel senders to the control unit. The navigation system does not use the signals from the ABS wheel senders to locate the position of the vehicle; this function is accomplished by basing the calculations on the speed of the vehicle.

Note: For more information, consult the Self Study Program No. 69 “Radionavigation system”.

LAYOUT The Xenon headlights use (GDL) gas discharge light bulbs for the dipped beams. The advantages of these new generation lights in relation to the existing halogen ones are: â&#x20AC;&#x201C; A light output up to three times more than conventional bulbs, making it possible to use bulbs as low as 35 watts. â&#x20AC;&#x201C; The useful life is approximately 1500 hours, which is more than the average life of a vehicle. Slave control â&#x20AC;&#x201C; By using a special configuration for the unit J344 reflector, lens and glass, greater beam travel is achieved and better light dispersion occurs close to the vehicle. This makes it possible to improve road edge illumination and thus reduce driver vision fatigue. The mounting of Xenon lights makes it obligatory to fit headlight reach adjustment and a headlight washer system. The components which are found in each Protected by copyright.

These senders are required to determine the inclination of the body under load. One sender is mounted on the front stabiliser bar to determine the height of the front part of the vehicle, and another on the longitudinal arm of the rear right hand side wheel for the rear vehicle height.

Note: The gas discharge lamps are supplied with high voltage, making it essential to take precautions when working on this system.

SYNOPTIC CHART The functions assumed by the system are: â&#x20AC;&#x201C; Lighting the gas discharge bulb â&#x20AC;&#x201C; Adjustment of light reach â&#x20AC;&#x201C; Self diagnosis

On the contrary, the signals needed for light reach adjustment are received directly from the master control unit on the left headlight. At the same time, the calculation is sent to the slave control unit fitted on the right headlight, which in turn governs the operation of the servomotor on this light. Both units have a self diagnosis system which can be consulted using the fault reader.

Each control unit assumes the function of lighting the gas discharge bulb when it receives the signals needed to correctly carry out this operation.

Electrode

GAS DISCHARGE LIGHT BULBS L13/14

Gas filled glass bulb

Light is created in gas discharge bulbs by passing a voltage arc between two electrodes in a glass bulb. The bulb size is about the size of a bean and is filled with gas. Due to the chemical composition of the gas, the light which is generated has a high percentage of blue and green colours.

Voltage arc

Electrode

ENERGISING The capacitor is responsible for providing the electrical supply to the bulb. The voltage arc is necessary in order to ignite the gas discharge bulb, which requires a high voltage of several thousand volts (approx. 28kV). Once the bulb is lit, it can then be supplied with alternating current having a frequency of approximately 400Hz.

D80-35

CAPACITOR J426/427 The capacitor has two connectors, one input with three terminals from the control unit, and the other is an output having two terminals for the bulb holders. The capacitor has two circuits, one of which is Protected by copyright.

ENERGISING The control unit supplies the two capacitor circuits using three cables, one of which is common for both circuits. The ignition circuit is energised with an alternating voltage exceeding 500 V. The lights are kept on by an energising voltage which could vary between 30 and 112 V.

If a stop is made (v < 1 km/h) while the ignition is switched on and a change in vehicle load is detected (for example, another person gets into the vehicle), the time interval adjustment will be reset to the initial value. This ensures that the headlight reach adjustment will be immediately adapted to the new load conditions. If the load does not change, (for example, when stopping before traffic lights) the adjustment will continue with the greater time interval. This method ensures stability in the headlight reach adjustment, since it will only react when load conditions are changed, and not due to dynamic effects, such as when braking or accelerating.

The control unit makes a basic setting according to the inclination of the body. When the vehicle is started, a theoretical value for the operation of the headlight adjustment servomotors is transmitted, regardless of whether the dipped beams are on or not. Afterwards, the modifications to the theoretical figure for headlight reach adjustment will only be sent to the servomotors if the dipped beams are on. The vehicle inclination is calculated by determining the difference between the readings from the front and rear levelling senders. When the initial calculation has been completed, new readings will only be taken when the vehicle is driven at a constant speed. At first, the readings are taken at short time

High voltage circuit, up to 28 kV

D80-39

BULB LIGHTING The heating phase remains active for about 5 seconds after bulb illumination. The control unit will supply the capacitor with approximately 30 V at 400 Hz. The approximate consumption of the bulb during this phase could reach 17 A. The normal operating supply period begins after heating phase. The voltage will vary from 68 to 112 V at a frequency of 400 Hz. During this phase, the control unit will supply the capacitor with a regulated voltage, whose variation will be affected by the bulb voltage consumption, in other words, its internal resistance.

The control unit energises the capacitor with alternating current, adapting the voltage and frequency in such a way that during the different operating phases, there will always be a correct voltage arc generated in the bulb. Three different phases of bulb operation can be distinguished: – Initial illumination – Heating – Operating supply The initial illumination period is limited to approximately 500 ms. During this phase, the control unit will supply the capacitor with approximately 500 V. The output voltage from the capacitor at the moment of illumination reaches 28 kV.

LAYOUT In this situation, the warning light will remain on permanently. The system will warn of the presence of an object when the distance is less than 160 cm, by emitting an intermittent acoustic signal. The closer the vehicle is to the object, the greater the frequency of the acoustic signals. When the distance is reduced to 20cm, the intermittent warning becomes continuous. There is one buzzer located at the front and another at the rear. The buzzer nearest to the object emits the warning signal.

The parking aid system operates with the aid of ultrasonic signals and assists the driver during parking manoeuvres, by giving a warning when the vehicle approaches an object. The system consists of: â&#x20AC;&#x201C; Four senders in the front bumper. â&#x20AC;&#x201C; Four senders in the rear bumper. â&#x20AC;&#x201C; Two warning buzzers â&#x20AC;&#x201C; A button for connection and disconnection with an integrated warning light. â&#x20AC;&#x201C; A control unit.

on when the trailer connector is plugged in. The control unit also uses the signal from this switch to deactivate the rear parking aid system when the trailer connector is plugged in.

SPEED SIGNAL The speed is used to determine when the vehicle begins to move. The control unit deactivates the parking aid system when the vehicle speed is greater than 20 km/h. D80-47

PARKING AID SENDERS The senders G203-206 are integrated in the front bumper and the G252-255 are in the rear bumper. Their task is to recognise the presence of objects in their monitoring zone (160 â&#x20AC;&#x201C; 0 cm). This is done by the emission of electrosonic waves (eco), which are reflected off an object back to the sender. The parking aid control unit J466 decides when the senders should emit the ultrasonic waves (eco). The senders capture the waves coming from an object and transform them into digital signals, which are then transmitted to the control unit.

Integrated circuit

SIGNAL APPLICATION The control unit calculates the distance to the object by analysing the eco travel time, in other words, the time elapsed between the instruction to transmit electrosonic waves and the reception of the digital signals from the sender. The distance is calculated by the application of the triangulation method. According to the distances, the object is known to be between the senders 2 and 3. The Pythagoras theory is used to determine the distance h (h = 44 cm). If the distance between the senders at the edges and an object does not change, the system will realise that we are driving parallel to a wall. In this case, the warning buzzer will be deactivated after 3 seconds and it will only be reactivated if the distance is reduced.

REPLACEMENT FUNCTION If the signal from any of the senders is missing, the control unit will deactivate the system. This will be indicated by the blinking of the warning light and the sound of the buzzers for a period of 3 seconds.

SWITCH E266 AND WARNING LIGHT K136 FOR PARKING AID The switch and the warning light for the parking aid are integrated in one single unit in the central console. Each action on the switch will cause it to send a negative signal to the parking aid control unit. The warning light will receive a positive signal from the parking aid control unit when the system is activated. If a fault is detected, the control unit will energise the warning light by sending positive pulses, causing it to blink twice per second (2 Hz).

SIGNAL APPLICATION The negative signal from the switch is used by the control unit to activate or deactivate the parking aid system REPLACEMENT FUNCTION If the switch signal is missing or shorted to earth, it will be impossible to activate or deactivate the system manually.

WARNING BUZZERS H15 AND H22

There are two warning buzzers, one (H15) is located at the front next to the control unit under the left seat. The other (H22) is located at the rear in the base of the left D pillar.

ENERGISING The buzzers receive a 12 V signal whose frequency varies according to the distance from the object (160cm 1Hz, 20cm 25 Hz, and at less than 20 cm, the signal is continuous). Note: When a fault is detected in the system, the control unit energises the buzzers for a period of 3 seconds.
