Pressure values are given as guidelines. The values given are for a fully laden vehicle or for motorway driving. Forvehicles with a chassis to be fitted with equipment which is likely to alter the axle loads, refer to the manufacturer'sinformation relating to the type, brand and operation of the vehicle.
Tyre pressures must be checked when cold. The increase in temperature during driving increases the pressure by0.2 to 0.3 bar .
If the pressure is checked when the tyres are warm, take this increase into account and never deflate the tyres.

Special notes
The high-pressure direct injection system is intendedto deliver a specific quantity of diesel to the engine at aspecific time.
DESCRIPTION
BOSCH 86-track computer controlling the injectionsystem.
The system consists of: a fuel pre-filter, a low-pressure pump, a fuel filter, a high-pressure pump, a pressure regulator mounted on the pump, an injector rail fitted with a diesel pressure sensor,
four solenoid injectors, an engine speed sensor, a camshaft sensor, a turbocharger air temperature and pressure sensor, a coolant temperature sensor, a diesel temperature sensor, an accelerator pedal potentiometer, a declutchable engine cooling fan control.
The common rail direct high-pressure injectionsystem works sequentially (based on the operation ofmultipoint injection for petrol engines).
This new injection system reduces operating noise,reduces the volume of pollutant gases and particlesand produces high engine torque at low enginespeeds thanks to a pre-injection procedure.
The high-pressure pump generates the high-pressure sent to the injector rail. The pressureregulator located on the pump controls the pressureaccording to the requirement determined by thecomputer. The rail supplies each injector through asteel pipe.
The injection computer receives information fromvarious sensors. It calculates the injectioncharacteristics (advance, pre-injection, injectiontime) and controls the opening of the injectors.
The computer: determines the value of injection pressure necessary
for the engine to operate correctly and then controlsthe pressure regulator. It checks that the pressure
value is correct by analysing the value transmitted bythe pressure sensor located on the rail, determines the injection time necessary to deliver the
right quantity of diesel and the moment wheninjection should start,
controls each injector electrically and individuallyafter determining these two values.
The high-pressure pump consists: three pumping pistons, a pressure regulator which controls the output
pressure, a piston cut-off solenoid valve which modulates the
pressure in accordance with the computer.
The computer controls: the idle speed regulation, the fuel supply (advance, flow and rail pressure), the fan assembly control, the authorisation to engage the air conditioning
compressor clutch, the control of the intake air heater.
Injection computer switches on the engine coolingfan and the coolant temperature warning light on theinstrument panel.

CHECKING SEALING AFTER REPAIR
Re-prime the circuit. To do this, start the low-pressurepump by switching on the ignition several times.
The system injects the diesel fuel into the engine at apressure of up to 1350 bar . Check that the injectorrail is depressurised before any work.
It is absolutely vital that you observe the tighteningtorque:
of the high-pressure pipes, of the injector flange, of the pressure sensor and pressure regulator.
When the high-pressure pump, injectors, supplyand return unions are removed, the ports should
be fitted with new and appropriate blanking piecesto prevent contaminants from entering.
Dismantling the interior of the high-pressure pumpis prohibited.
The fuel return pipe fitted to the injectors must bereplaced when it is removed.
Loosening a high-pressure pipe connection whenthe engine is running is prohibited.
You must respect the cleaning and safety advicespecified in this document when working on thehigh-pressure injection system.
After any operation, check that there are nodiesel leaks. Run the engine at idle speed untilthe engine cooling fan starts up, then accelerateseveral times with no load.
WARNINGThe engine must not run with diesel containing morethan 10% diester.
WARNINGALL PIPES REMOVED MUST BE REPLACED.

Cleanliness
INSTRUCTIONS TO BE FOLLOWED BEFOREOPENING THE FUEL CIRCUIT
Use new thinner for each operation (used thinnercontains impurities). Pour it into a clean receptacle.
For each operation, use a clean brush in goodcondition (the brush must not shed its bristles).
Use a brush and thinners to clean the connections tobe opened.
Blow compressed air over the cleaned parts (tools,cleaned the same way as the parts, connections andinjection system zone). Check that no bristles remainadhering.
Wash your hands before and during the operation ifnecessary.
When wearing leather protective gloves, cover themwith latex gloves.
INSTRUCTIONS TO BE FOLLOWED DURING THEOPERATION
As soon as the circuit is open, all openings must beplugged to prevent impurities from entering thesystem. The plugs to be used are available from theParts Stores. They must not, under anycircumstances, be reused .
Close the resealable bag, even if it has to bereopened shortly afterwards. The ambientatmosphere carries impurities.
All components removed from the injection systemmust be stored in a hermetically sealed plastic bagonce the plugs have been inserted.
The use of a brush, thinner, bellows, sponge ornormal cloth is strictly prohibited once the circuit hasbeen opened. In fact, these tools are liable to causedirt to enter the system.
If a component is being replaced, the newcomponent must not be removed from its packaginguntil it is ready to be fitted to the vehicle.

DIESEL INJECTIONFault finding - Introduction
FAULT FINDING PROCEDURE:
Use one of the diagnostic tools to identify the system fitted to the vehicle (reading the computer family,program No., Vdiag No., etc.).
Locate the Fault finding documents corresponding to the system identified. Take note of information contained in the Introduction sections. Read the faults in the computer memory and use the Interpretation of faults section of the documentation.
Reminder: Each fault is interpreted by a particular type of storage (fault present, fault stored in memory, faultpresent or stored). The checks specified for dealing with each fault are therefore only to be carried out if the faultshown by the diagnostic tool is described for its type of storage. The storage type should be considered when usingthe diagnostic tool following ignition switch-off and switch-on.
If a fault is interpreted when it is declared as stored, the conditions for applying fault finding appear in the notes box.If the conditions are not satisfied, use the fault finding strategy to check the circuit of the faulty part since the fault isno longer present on the vehicle. Perform the same operation when a fault is declared as stored by the diagnostictool but is only interpreted in the documentation as a present fault.
Carry out the conformance check (appearance of possible faults not yet identified by the system's self-diagnosticprocedure) and implement the associated fault finding strategies according to the result.
Confirm the repair (customer complaint disappears). Use the diagnostic procedure for each customer complaint according to the fault finding chart if the problem
persists.
TOOLING REQUIRED
To enter into dialogue with the injection computer: NXR and CLIP (Optima).
For miscellaneous electrical checks: Optima 5800 with optional garage multimeter and temperature sensor.
Connector A carries the Engine harness wires.
Connector A carries the Passenger Compartment harness wires.
WARNING:
Any fault finding procedure requiring work to be carried out on the high pressure injection system requiresfull understanding of the cleanliness and safety instructions in Section 13 of the Workshop Repair Manualfor the vehicle concerned.
This document introduces the generic fault finding procedure applicable to all:
Bosch MS6.3, Electronic version: MS6.3, Engine type number: 140 (bhp).
A Fault Finding Special Features Technical Note is available for every vehicle fitted with this computer.It covers all the fault finding special features in this document for the vehicle concerned.The following are required for carrying out fault finding on this system:
the fault finding special features Technical Note for the vehicle,
the wiring diagram of the function for the vehicle concerned,

NOTES The fault is detected:
if the measured pressure is more than 2300 mbar , when the + after ignition is switched on.
3.DEFThe measured pressure is outside the manufacturer's specification. Check that theturbocharger wastegate valve is operating correctly and check with a pressuregauge that the turbocharging pressure never exceeds 2.2 bar .
Checking the inlet manifold pressure sensor / air temperature sensor:
The sensor delivers a voltage proportional to the manifold pressure:
2.5 bar absolute ( 1.5 bar relative) = 4.65 V
0.2 bar absolute ( - 0.8 relative) = 0.4 V
Check first that the sensor is correctly fed with a voltage of + 5 V across tracks 1and 3 with the sensor connected.
Use a vacuum pump connected to the sensor's vacuum coupling to check that thesignal corresponds to the graph. Disconnect track 4 linking the computer to thesensor and connect the "+" lead of a multimeter (set at between 5 and 10 V ) totrack 4 of the sensor and the "-" lead to track 1 of the sensor (sensor earth stillconnected to the computer).
At atmospheric pressure, the voltage should be approximately equal to 1.7 V .
At a pressure close to 2.5 bar absolute, the voltage should be approximately equalto 4.65 V .
At a pressure close to 0.2 bar absolute, the voltage should be approximately equal
to 0.4 V .If the voltages do not correspond to the pressures, replace the sensor.

NOTES The fault is detected if:
the fuel temperature sensor voltage is less than 0.250 V . the + after ignition is switched on.
CC.0Disconnect the injection computer connector and the fuel temperature sensorconnector.
Check the resistance of the fuel temperature sensor and its earth insulation (seeconformity check): the resistance should be 2575 at 20 C .
Check the continuity and insulation of the following tracks:track 1 of the fuel temperature sensor track A15 of the injection
computer track 2 of the fuel temperature sensor track A30 of the injection
computer
If the fault is still there, contact the Techline.
AFTER REPAIR
Deal with any other possible faults.Clear the fault memory.Switch off the ignition.Carry out a road test, then a check with the diagnostic tool.
