00-0 General About this Workshop manual General information
Certified engines
This Service Manual contains technical data, descriptions and maintenance and repair instructions for standard model Volvo Penta products. A list of these products may be found in the section Specifications.
When carrying out service and repair on emission-certified engines, it is important to be aware of the following:
The product designation and the serial number and specification is indicated on the engine decal or type plate. This information must be included in all correspondence regarding the product. The service manual is produced primarily for the use of Volvo Penta workshops and their qualified personnel. It is assumed that any person using the Service Manual has a fundamental knowledge of the product and is able to carry out mechanical and electrical work to trade standard. Volvo Penta continually develops its products; we therefore reserve the right to make changes. All information in this manual is based on product data which was available up to the date on which the manual was printed. New working methods and significant changes introduced to the product after this date are communicated in the form of Service bulletins.
Spare Parts Spare parts for the electrical and fuel systems are subject to various national safety standards. Volvo Penta Original Spare Parts meet these standards. No damage of any kind caused by the use of spare parts not approved by Volvo Penta will be compensated by any warranty undertaking.
Certification means that an engine type has been inspected and approved by the relevant authority. The engine manufacturer guarantees that all engines of the same type are manufactured to correspond to the certified engine. This places special demands on service and repair work, namely: •
Maintenance and service intervals recommended by Volvo Penta must be complied with.
•
Only spare parts approved by Volvo Penta may be used.
•
Service on injection pumps, pump settings and injectors must always be carried out by an authorized Volvo Penta workshop.
•
The engine must not be converted or modified, except with accessories and service kits which Volvo Penta has approved for the engine.
•
No changes to the exhaust pipe and engine air inlet duct installations may be made.
•
No warranty seals (where present on the product) may be broken by unauthorized persons.
The general instructions in the Operator's Manual concerning operation, service and maintenance apply. IMPORTANT! Neglected or poorly-performed care/service and the use of spare parts not approved by Volvo Penta, will mean that AB Volvo Penta no longer guarantees that the engine conforms to the certified model. Volvo Penta accepts no responsibility for damage or costs arising as a result of failure to follow the above mentioned standards.

Repair instructions Introduction
Our Mutual Responsibility
The working methods described in this manual are based on a workshop scenario where the product is mounted in a workholding fixture. Maintenance work is often carried out in situ, in which case - if nothing else is indicated - using the same working methods as the workshop.
Each product comprises a large number of interacting systems and components. A deviation from the technical specification may dramatically increase the environmental impact of an otherwise reliable system. It is therefore critical that the stated wear tolerances be adhered to, that systems which can be adjusted be correctly set up and that only Volvo Penta Original Parts are used. The intervals in the care and maintenance schedule must be followed. Some systems, e.g. fuel systems, often require special expertise and test equipment. A number of components are factory-sealed, for among other things environmental reasons. Warranty-sealed components may not be worked on without authorization to perform such work.
Warning symbols that occur in the service manual. For significance, refer to Safety Information.
DANGER! WARNING! CAUTION! IMPORTANT!, NOTE! are by no means comprehensive since not everything can be foreseen as service work is carried out in the most varied of circumstances. We call attention to risks that may occur due to incorrect handling during work in a well-equipped workshop using working methods and tools tried and tested by us. The service manual describes work operations carried out with the aid of Volvo Penta Special Tools, where such have been developed. Volvo Penta Special Tools are designed to ensure the safest and most rational working methods possible. It is therefore the responsibility of anyone using tools or working methods other than those we recommend to ensure that no risk of personal injury or mechanical damage is present, or that malfunction can result. In some cases, special safety regulations and user instructions may be in force for the tools and chemicals mentioned in the Service Manual. These rules must always be observed, so there are no special instructions about this in the workshop manual. By following these basic recommendations and using common sense it is possible to avoid most of the risks involved in the work. A clean workplace and a clean product will eliminate many risks of personal injury and malfunction.
Remember that most chemical products, incorrectly used, are harmful to the environment. Volvo Penta recommends the use of biodegradable degreasers whenever components are cleaned, unless otherwise specified in the Service Manual. When working outdoors, take especial care to ensure that oils and wash residues etc. are correctly properly for destruction.
Tightening torque Tightening torques for vital fasteners that must be applied using a torque wrench are indicated in the Service Manual, chapter Tightening torques and in the Manual's work descriptions. All torque indications apply to clean threads, bolt heads and mating faces. Indicated torque data apply to lightly-oiled or dry threads. If lubricants, locking fluids or sealants are required for fasteners, the correct type will be indicated in the job description.
Torque, angle tightening When torque/angle tightening, the fastener is tightened to a specified torque, and tightening then continues through a pre-determined angle. Example: For 90° angle tightening, the fastener is turned an additional 1/4 turn in one sequence, after the specified tightening torque has been achieved.
Above all, when working on fuel systems, hydraulic systems, lubrication systems, turbochargers, inlet systems, bearings and seals, it is of the utmost importance that dirt and foreign objects are kept away, as malfunctions or shortened service intervals may otherwise result.

Lock nuts Removed lock nuts may not be re-used; they must be replaced by new ones, as locking properties are impaired or lost with re-use. In the case of lock nuts with plastic inserts, the tightening torque indicated must be reduced if the nut has the same nut height as a standard, all-metal hexagonal nut. Reduce the torque by 25% for bolt sizes of 8 mm or larger. In the case of lock nuts with plastic inserts with a high nut-height (where the all-metal thread is as high as a standard hexagonal nut), the indicated torque applies.
Strength Classes Nuts and bolts are grouped into different strength classes. Their classification is shown by a marking on the bolt head. Markings of a higher number indicate stronger material. For example, a bolt marked 10-9 is stronger than one marked 8-8. For this reason, it is important that when bolted joints are removed they are returned to their original locations on re-assembly. When replacing bolts, check the applicable Spare parts catalog to ensure the correct bolt is used.
Sealing compounds etc. To ensure service work is correctly carried out, it is important that the correct type of sealants and locking fluids are used on joints where such are required. In each service manual section concerned, the sealants used in product manufacture are indicated. The same sealants, or sealants with equivalent properties, must be used for maintenance work. A service technician should have a basic knowledge of how sealing compounds are handled, and are able to assess the condition of existing seals. Make sure that mating surfaces are dry and free from oil, grease, paint and anti-corrosion agent before applying sealant or locking fluid. Always follow the manufacturer's instructions regarding applicable temperatures, hardening times and such. Two basic types of compound are used: RTV preparations (Room Temperature Vulcanizing). Used most often together with gaskets, e.g. sealing gasket joints, or are brushed on gaskets. RTV sealants are completely visible when the part has been removed. Old RTV sealant must be removed before the component is sealed again. Use denatured alcohol.
4
Anaerobic agents. These agents cure in the absence of air. These preparations are used when two solid components, e.g. two cast components, are fitted together without a gasket. Common uses are also to lock and seal plugs, stud threads, taps, oil pressure monitors etc. Hardened anaerobic preparations are vitreous and for this reason, the preparations are colored to make them visible. Hardened anaerobic preparations are highly resistant to solvents, and old compound cannot be removed. On re-assembly, it is important to carefully degrease and wipe dry components first, before applying new sealant in accordance with the instructions.
Safety regulations for fluorocarbon rubber Fluorocarbon rubber is a common material in seal rings for shafts, and in O-rings, for example. When fluorocarbon rubber is exposed to high temperatures (above 300°C/572°F), hydrofluoric acid can form. This is highly corrosive. Contact with the skin can result in severe chemical burns. Splashes in your eyes can result in corrosive wounds. If you breathe in the fumes, your lungs can be permanently damaged.
WARNING! Seals must never be cut with a torch, or be burnt afterwards in an uncontrolled manner. Risk for poisonous gases.
WARNING! Always use chloroprene rubber gloves (gloves for chemicals handling) and goggles. Handle the removed seal in the same way as corrosive acid. All residue, including ash, can be highly corrosive. Never use compressed air to blow clean. Put the remains in a plastic container, seal it and apply a warning label. Wash the gloves under running water before removing them. The following seals are most probably made from fluorocarbon rubber: Seal rings for the crankshaft, camshaft, idler shafts. O-rings, regardless of where they are installed. Orings for cylinder liner sealing are almost always made of fluorocarbon rubber. Please note that seals which have not been exposed to high temperature can be handled normally.

05-1 Safety Instructions
!
Immobilize the engine by turning off the power supply to the engine at the main switch (switches) and lock it (them) in the off position before starting work. Post a warning notice at the main circuit breaker.
!
Avoid opening the coolant filling cap when the engine is hot. Steam or hot coolant can spray out and system pressure will be lost. Open the filler cap slowly, and release the pressure in the cooling system if the filler cap or valve has to be opened, or if a plug or coolant hose has to be removed when the engine is hot.
!
As a rule, all service operations must be carried out with the engine stopped. However, some work, such as adjustments, will require the engine to be running. Approaching an engine which is running is a safety risk. Bear in mind that loose clothing or long hair can fasten in rotating parts and cause serious personal injury.
!
Hot oil can cause burns. Avoid skin contact with hot oil. Ensure that the lubrication system is not under pressure before any work is begun. Never start or operate the engine with the oil filler cap removed, because of the risk of oil ejection.
!
Be aware of hot surfaces (exhaust pipes, turbos, charge air pipes, starting heaters etc.) and hot fluids in pipes and hoses on an engine that is running or has just stopped. If work is done adjacent to a running engine, a careless movement or a dropped tool may in the worst case lead to personal injury.
!
Never start the engine without installing the air filter. The rotating compressor turbine in the turbocharger can cause severe injury. Foreign objects entering the intake ducts can also cause mechanical damage. Install all protective covers before the engine is started.
!
Ensure that the warning symbols or information decals on the product are always clearly visible. Replace decals which have been damaged or painted over.
!
Only start the engine in a well-ventilated space. When running in a confined space, exhaust fumes and crankcase gases must be led away from the engine bay or workshop area.
!
Avoid getting oil on your skin! Protracted or repeated exposure to oil can cause skin to become dry. Irritation, dryness, eczema and other skin problems may then result. From a health standpoint, used oil is more dangerous than new. Use protective gloves and avoid oilsoaked clothes and rags. Wash regularly, especially before eating. Use suitable barrier creams to counteract drying out of the skin and to aid dirt removal.
!
The majority of chemicals e.g. engine and transmission oils, glycol, gasoline, and diesel oil, together with chemicals for workshop use such as degreasing agents, paints and solvents, are injurious to health. Carefully read the instructions on the product packaging! Always follow a product's safety directions, e.g. use of protective mask, glasses, gloves etc. Ensure that other personnel are not exposed to substances that are injurious to health. Ensure good ventilation. Handle used and leftover chemicals in the prescribed manner.
!
Stop the engine and turn off the electrical supply at the main switch(es) before carrying out work on the electrical system.
!
Clutch adjustments must be carried out with the engine stopped.

05-1 Safety Instructions
!
Always use protective glasses or goggles when carrying out work where a risk of splinters, grinding sparks, splashes from acid or other chemicals is present. Your eyes are extremely sensitive; injury may cause blindness!
!
Never start the engine with the valve cover removed. There is a risk of personal injury.
!
Never use start gas or similar products as a starting aid. They may cause an explosion in the inlet manifold. Danger of personal injury.
!
Stop the engine before working on the cooling system. Marine engines: Close the sea cock / cooling water inlet valve before work on the cooling system is begun.
!
All fuels, as well as many chemicals, are flammable. Do not allow open flames or sparks in their vicinity. Gasoline, some thinners, and hydrogen gas from batteries are extremely flammable and explosive when mixed with air in the correct proportions. No Smoking! Ensure that the work area is well ventilated and take the necessary safety precautions before welding or grinding work is begun. Always ensure that there are fire extinguishers close at hand in the work area.
!
Make sure that oil, fuel-soaked rags, and used fuel and oil filters are stored in a safe manner. Rags soaked in oil can spontaneously ignite under certain circumstances. Used fuel and oil filters are environmentally hazardous waste and must be handed to an approved waste management facility for destruction, as must any used lubrication oil, contaminated fuel, paint residue, solvents, degreasers and wash residue.
!
Batteries must never be exposed to open flames or electric sparks. Never smoke in the vicinity of the batteries; they generate hydrogen gas when charged, which is explosive when mixed with air. This gas is easily ignited and highly explosive. A spark, which can be caused by incorrect battery connection, is sufficient to cause a battery to explode and cause damage.
!
Never work alone when removing heavy components, even when using lifting devices such as locking tackle lifts. When using a lifting device, two people are usually required to do the work - one to take care of the lifting device and the other to ensure that components are lifted clear and not damaged during the lifting operations.
!
The existing lugs on the engine should be used for lifting. Always check that the lifting equipment used is in good condition and has the load capacity to lift the engine (engine weight including gearbox or extra equipment). For safe handling and to avoid damaging components fitted to the top of the engine, the engine must be lifted with a correctly adjusted lifting boom. All chains or wires must run parallel to each other and as perpendicular to the engine as possible. If other equipment attached to the engine has altered its center of gravity, special lifting devices may be needed to obtain the correct balance for safe handling. Never perform any work on an engine that is only suspended from the lifting equipment.
Do not touch the connections during start attempts. Sparking hazard! Do not lean over batteries.
!
28
Never transpose the positive (+) and negative (-) battery posts when installing batteries. Such a transposition can result in serious damage to electrical equipment. Refer to the wiring diagram. Always use protective goggles when charging and handling the batteries. Battery electrolyte contains sulfuric acid which is highly corrosive. Should the battery electrolyte come into contact with unprotected skin, wash it off immediately using soap and copious amounts of water. If you get battery acid in your eyes, flush at once with copious amounts of water and seek medical assistance immediately.

05-1 Safety Instructions
!
The components in the electrical and fuel systems on Volvo Penta products are designed and manufactured to minimize the risk of fire and explosion. The engine must not be run in areas where there are explosive materials.
!
Exercise extreme caution when leak-detecting on the fuel system and testing the fuel injector nozzles. Use eye protection. The jet from a fuel nozzle has very high pressure and great penetration power. Fuel can force its way deep into body tissue and cause severe injury. There is a risk of blood poisoning (septicemia).
!
Only use fuels and lubricating oils recommended by Volvo Penta. Refer to the Operator's Manual for the product in question. Use of fuels that are of a lower grade may damage the engine, the injection pump and the injectors. On a diesel engine, low grade fuel can cause the control rod to bind and the engine to over-rev, with the risk of engine damage and personal injury as a result. Low fuel and oil grades may result in high service, maintenance and repair costs.
!
Never use a high-pressure washer for cleaning the engine. Pay attention to the following when using a highpressure washer on components other than the actual engine: Never direct the water jet at seals, rubber hoses or electrical components.
!
Fuel delivery pipes must not be bent or straightened under any circumstances. Cracks may occur. Damaged pipes must be replaced.
!
When working on the engine; perform leakage and function test as necessary.

The starter motor is installed in the flywheel housing, on the right-hand side of the engine. The starter motor relay is connected between battery positive and EMS2. When the relay is to be activated during the starting sequence EMS2 alter the potential of the output. The starter motor solenoid is engaged via the starter relay, which is activated when the starter key is turned to position III. The starter relay (1) is installed on the side of the starter motor solenoid. If there is no power module installed, a first-start relay is also included in the starter motor circuit. This is located underneath the plastic housing beside the stop button bracket. Overheating protection The starter motor circuit is automatically cut for 30 seconds to protect the starter motor against overheating. Leave the starter motor to cool for at least five minutes (if possible) before making a new start attempt.

Unit injector The unit injectors are installed on the cylinder head, underneath the valve cover. The amount of fuel injected and injection duration is controlled by the control unit, via electromagnetically controlled fuel valves in the unit injectors. This means that the engine always receives the correct volume of fuel in all operating conditions, which offers lower fuel consumption, minimal exhaust emissions etc. The unit injectors are made and classified by tolerance. Each unit injector is marked with a code on the top side of the electric connection. If an injector is replaced, the new code must be programmed for the cylinder concerned using VODIA.
Piston cooling switch (D12, D16) A valve is installed in the oil filter bracket which opens or closes the oil supply for piston cooling, depending on oil pressure. If the oil pressure is below 240 kPa (35 PSI), the valve closes the oil supply for piston cooling. The piston cooling pressure is monitored by a pressure monitor. The output signal from the pressure monitor can only have two distinct positions, on/off, in the same way as a relay output. The monitor is supplied with current from the EMS2. A preset pressure limit of 150 kPa (22 PSI) determines when the monitor switches on. The monitor opens if the pressure exceeds this value. At idle, the monitor can be closed without a fault code being set.
Sensor, piston cooling (D11) The sensor measures piston cooling pressure and is located in front of the engine. The sensor is an active sensor, i.e. the sensor requires a supply voltage of +5 Volt. The sensor provides an output signal whose voltage is proportional to the pressure that the sensor measures.
Sensor, fuel pressure The sensor measures fuel pressure and is located on the fuel filter bracket. The sensor is an active sensor, i.e. the sensor requires a supply voltage of +5 Volt. The sensor provides an output signal whose voltage is proportional to the pressure that the sensor measures.

Sensor, air inlet pressure / intake manifold temperature The air inlet pressure and intake manifold temperature are measured by a combined sensor, which is located in the inlet manifold. The sensor is supplied by a 5 Volt reference voltage from the engine control module.
D11, D13, D16
The air inlet pressure sensor measures the absolute pressure, which is the sum of the air inlet pressure and atmospheric pressure. 300 kPa (44 PSI) corresponds with a charge pressure of 200 kPa (29 PSI) when atmospheric pressure is 100 kPa (15 PSI)). The sensor provides a voltage signal which is proportional to absolute pressure. The intake manifold temperature sensor consists of a non-linear resistor, whose resistance varies with charge air temperature. The resistance falls as the temperature rises.

Sensor, oil pressure / oil temperature, engine Oil temperature and oil pressure are measured by a combined sensor. The sensor is supplied with 5 Volt from the engine control module. The sensor is installed on the oil filter bracket and measures the pressure in the main oil gallery. The oil temperature sensor consists of a non-linear resistor, whose resistance varies with engine oil temperature. The resistance falls as the oil temperature rises. The pressure signal gives an output signal whose voltage is proportional to the pressure that the sensor measures. D9, D12, D16
Sensor, camshaft position The camshaft position sensor is located furthest back on the right side of the engine and is identical with the engine speed sensor. The sensor is inductive. The sensor reads a toothed wheel with seven teeth (six of which have the same spacing) on the camshaft. The impulses from the cam position sensor provide the control unit with information about the cylinder which is next in line for fuel injection.
Sensor, engine speed (flywheel) D11, D13
The sensor is located on top of the flywheel housing and is identical with the camshaft position sensor. The sensor is inductive. This reads the crankshaft angle and speed by means of grooves in the flywheel. The signal is sent to the control unit, which calculates the injection advance and the amount of fuel to be injected.

Engine control unit (EMS2) The control unit checks and controls the unit injectors, to ensure that the correct volume of fuel is injected into each cylinder. It also calculates and adjusts the injection advance. Regulation is mainly done with the aid of the engine speed sensors and the combined sensor for air inlet pressure / intake manifold temperature. The EMS2 system processor is located in the control unit, unit, protected from water and vibration. The processor receives continuous information about:
• Engine Speed • Throttle opening • Oil pressure • Oil temperature • Crankcase pressure • Air inlet pressure / intake manifold temperature • Fuel pressure • Fuel alarm, water in fuel • Camshaft position • Coolant level / oil level • Coolant temperature • Piston cooling pressure The information provides information about current operation conditions and allows the processor to calculate the correct fuel volume, monitor engine status etc.
Sensor, crankcase pressure The sensor that is measuring the crankcase pressure is located on the valve housing. The sensor provides an output signal whose voltage is proportional to the pressure that the sensor measures. The sensor is supplied with 5 Volt from the engine control module.
Switch, lube oil level (optional) (D9, D11, D12) The switch is located on the left-hand side of the oil pan. The switch can assume two states, on/off. When the oil level is correct, the monitor is on, i.e. a current flows to the EMS2.

Oil level/temperature sensor (D9CC, D13, D16) The sensor is located in the oil sump. The purpose of the level sensor is to detect if the oil level becomes too low. A current is passed through the sensor and the voltage measured across it is then proportional to the oil level. A alarm signal is sent when the oil level is too low. The temperature sensor consists of a non-linear resistor, where the resistance is dependent on the temperature of the resistor body. The resistance drops as temperature rises.
Switch, coolant level The switch is located under the coolant expansion tank. The level monitor comprises two parts, the actual monitor and a magnetic float built into the expansion tank. The monitor senses the position of the magnetic float. When coolant level drops, the float acts on the level monitor whose resistance drops to zero whereupon a circuit either closes (old model) or opens (new model).

Water switch, secondary fuel filter A switch is located underneath the secondary fuel filter in the water trap. Its task is to discover water in the fuel system. The switch consists of two copper pins, between which resistance is measured. When the resistance falls below a limit value (which happens when water gets into the fuel), the control module receives an alarm signal.

SDU (Shutdown Unit) The shutdown unit is an independent safety system to stop the engine in case of serious malfunction. The SDU is designed to fulfill all classification societies demands on safety system for propulsion engines and generator sets. On D9 and D16 engines the SDU controls a fuel cutoff valve which activates in case of shutdown. D13 engines have a power relay that opens and cuts power to EMS2 in case of shutdown. P0011559
The sensors to the SDU are type approved switches for oil pressure, gear oil pressure and coolant temperature. The switch level is designed to be activated after the EMS2 normal alarm and derate operation. The SDU can be overridden and will therefore temporarily not shut down the engine if the operator activates this function. Over speed shut down is not affected and is always active. Overspeed pickup (unique sensor) is placed on the flywheel to measure over speeding of engine, 15% over nominal speed. When replacing the SDU it must be configured manually. The SDU only consists of hardware, no software. The SDU indicates status on its outputs. In an MCC system the SDU is connected to an MCU panel. In an EVC system the SDU is connected to an SDU panel.

Fuel control The amount of fuel injected into the engine and the injection advance are fully electronically controlled, via fuel valves and the unit injectors, once the control unit has analyzed the engine’s fuel requirements. This means that the engine always receives the correct volume of fuel in all operating conditions, which offers lower fuel consumption, minimal exhaust emissions etc. The control unit checks and monitors the unit injectors to ensure that the correct volume of fuel is injected into each cylinder, and it calculates and adjusts the injection advance. Regulation is mainly done with the aid of the engine speed sensors and the combined sensor for air inlet pressure / intake manifold temperature. The control unit controls the unit injectors via a signal to the electromagnetically operated fuel valve in each injector, which can be opened and closed. When the fuel valve is open, fuel flows through the holes in the unit injectors and out through the fuel duct. Fuel is not injected into the cylinders in this phase. When the fuel valve is closed, pressure is built up by the mechanically driven pump piston in the unit injector. When enough pressure has been built up, fuel is injected into the cylinder via the nozzle part of the unit injector. The fuel valve is re-opened and pressure in the unit injector falls at the same time as fuel injection to the cylinder ceases. The control unit receives signals from various sensors on the engine, which allow it to decide when the fuel valve should be opened and closed.
Calculation of fuel quantity The quantity of fuel to be injected into the cylinder is calculated by the control unit. The calculation gives the time when the fuel valve is closed (fuel is injected into the cylinder when the fuel valve is closed). The parameters which govern the amount of fuel injected are:
• Demanded engine speed • Engine protection functions • Intake manifold temperature • Air inlet pressure Normal start Both the camshaft sensor and flywheel sensor function normally. The engine is cranked until the engine control unit discovers that cylinder 1 is next in line for injection. Fuel is injected and the engine starts.

Starting without the camshaft sensor If the engine control unit discovers that the camshaft signal is not available, the engine control unit will still attempt to start the engine. When the engine control unit detects a break in the pulse train from the flywheel sensor, one of the cylinders is in the position for injection, but the engine control unit does not know which one. The engine control unit guesses which cylinder is next in line, and injects fuel at the same time as it monitors engine speed to see if it increases. If engine speed does not increase, the guess was wrong and the engine control unit tries again. It will take a bit longer time to start the engine, but it will start with no problems apart from setting a fault code.
Starting without the flywheel sensor If the engine control unit discovers that the flywheel signal is not available, the engine control unit will still attempt to start the engine. Injection will be monitored using information from the camshaft sensor. Injection will not be as exact as normal, and the engine will have reduced power. If the engine starts, idling speed will be unstable. The engine control unit will not be able to do any cylinder balancing.
Cylinder balancing During idling, the control unit can provide the cylinders with different amounts of fuel. This is to give the engine more even idling. At higher engine speeds, all cylinders receive the same amount of fuel.
Diagnostic Function The EMS system has a built-in diagnostic function which can discover any faults in the engine and sensors. The function of the diagnostic function is to discover and localize any function faults in the EMS system, to protect the engine and guarantee continued operation if a serious function fault should occur.
Idling adjustment (low idle) Idling speed can be adjusted to a value between 500– 750 rpm.

Repair Instructions General advice on working with EMS engines The following advice must be followed to avoid damage to the engine control unit and other electronics. IMPORTANT! The system must be switched off and the system current disconnected when any of the connectors on the engine control unit is connected or disconnected. •
Never disconnect the current with the main switches when an engine is running.
•
Never undo a battery cable when the engine is running.
•
Turn the main switches off or disconnect the battery cables during quick charging of the batteries. NOTICE! During normal trickle charging, it is not necessary to turn the main switches off.
•
Only batteries may be used for start help. A help start device can produce a very high voltage and damage the control unit and other electronics.
•
If damage is discovered in a cable harness the two 36-pin connectors for the enginecontrol unit and the 8-pin connector between the engine and the EVC system must be disconnected.
•
If a connector is disconnected from a sensor, be very careful to avoid allowing the contact pins to come into contact with oil, water or dirt.
Electrical Welding IMPORTANT! Undo all connectors from the engine control unit before you start electric welding. IMPORTANT! Cut the engine current before the control unit connector is disconnected. Cut the current with the main switches. Then disconnect all connections to the alternator. Undo the connector from the engine control unit and from the power supply unit. Please refer to more detailed instructions in the ”Workshop manual group 21–26, ”Control unit, changing”. Connect the welder earth clamp to the component to be welded, or as close as possible to the weld site. The clamp must never be connected to the engine or in such a way that current can pass through a bearing. IMPORTANT! After welding is completed, the disconnected components, such as alternator cables and battery cables must be connected in the correct order.

Fault tracing of cables and connectors Special Tools: 9812519, 9998482.
Check all connectors visually Check the following:
Contact problems Intermittent contact or temporary recurring faults can be difficult to fault trace, and are frequently caused by oxidation, vibration or poorly terminated cables.
•
Look for oxidation, which can impair contact in connectors.
Wear can also cause faults. For this reason, avoid disconnecting a connector unless it is necessary.
•
Check that terminals are undamaged, that they are correctly inserted into their connectors, and that the cable is correctly terminated in the terminal.
Other contact problems can be caused by damage to pins, sockets and connectors etc.
•
•
Check that there is good mechanical contact in the connector. Use a loose pin to check this. IMPORTANT! The multi-pin connectors for the engine control unit must only be checked with gauge 9998482. Carefully insert gauge 9998482 into the multipin connector. Pull and push the connector in and out a few times and feel whether the terminal socket grasps the tool. If the terminal socket does not grasp, or if it feels slack, the connection pins should be changed. Please refer to ”Joining electrical cables for multi-connector” Check the secondary locking in the connector.
Shake cables and pull connectors during measurement, to find where the cable is damaged. Contact resistance and oxidation Resistance in connectors, cables and junctions should be close to 0 Ω. A certain amount of resistance will occur, however, because of oxidation in connectors. If this resistance is too great, malfunctions occur. The amount of resistance that can be tolerated before malfunctions occur varies, depending on the load in the circuit. Open circuit Possible reasons for faults could be chafed or broken cables, or connectors which have come undone. Use the wiring schedule to check the cable harnesses which are relevant to the function. Start off with the most probable cable harness in the circuit. Check the following:
•
If possible, shake the cables and pull the connectors during measurement to discover whether the cable harness is damaged.
•
Check that the cables are not damaged. Avoid clamping cables in tight bends close to the connector.
•
Check the function of the secondary locking.
62
•
Disconnect the relevant connector at each end of the cable harness.
•
Use multimeter 9812519 to measure the resistance between the ends of the cable. Nominal value close to 0 Ω.
•
If possible, shake the cables and pull the connectors during measurement to discover whether the cable harness is damaged.
•
Check the next cable harness in the wiring schedule if no fault has been found.

Fault tracing the charging system
Special Tools: 9812519.
Battery
Generally about alternators: The voltage output from an alternator must be limited to prevent the elecrolyte in the battery to evaporate. The alternator output is regulated (limited) by the voltage regulator in the alternator. The maximum current that the alternator can deliver at regulated voltage output depends on the alternator revolution. To make the alternator charging more efficient a sense cable between the alternator and the battery+ can be added to compensate if there is a voltage drop in the cable between the alternator and the battery+.
1 Check that all connectors at the battery is correctly assembled.
When the engine is started an excitation current is needed to “wake up” the alternator. NOTICE! It is the consumers (batteries included) which decides the output current from the alternator.
Measurements
2 Check the conditions of the cables to the battery. 3 Check the water level in the battery. 4 Check, if possible, the specific gravity of all cells. when no charge 1 Check the alternator belt tension. 2 Check that all connectors at the alternator and at the battery is correctly assembled. 3 Check the condition of all cables in the charging system. 4 Check the brushes length and condition. 5 Change, if possible, the regulator.
1 Engine off.
when undercharge
2 Use multimeter 9812519 to do a voltage measurement over the battery. The nominal voltage over a full loaded battery is approx. 12.6V or 25.2V.
1 Check the alternator belt tension.
3 Engine on. Run at 1500 rpm. 4 Use multimeter 9812519 to do a voltage measurement over the battery. The nominal charging voltage over the battery should be approx. 13.6–14.4 V or 27.8–28.6 V (if the sense cable is connected).
2 Check that all connectors at the alternator and at the battery is correctly assembled. 3 Check the condition of all cables in the charging system. 4 Check the brushes length and condition. 5 Change, if possible, the regulator. when overcharge 1 Change, if possible, the regulator.

Energizing sequence 1
When the main switch is closed, the engine control unit pin A8 (main relay hold) gets battery potential. Main relay is not activated. The PCU and HCU are energized (via the engine connector pin 4).
2
When the starter key is turned to position I (terminal 15a on the starter switch is connected to pin 30), the engine control unit pin A58 receives an activation signal from the PCU via pin 5 in the engine connector. Pin A8 alter its potential to approx. 0.8 V and the main relay activates. When the ignition is switched, the EVC equipment such as the control panels and instruments are activated. All relays connected to the starter switch and start / stop panels are activated to supply current to equipment which does not belong to the EVC.

NOTICE! The following must be done before fault tracing continues, to avoid changing functional sensors: •
If there is an active / inactive fault code Remove the connector from the sensor. Check that there is no oxidation and that the connector pins are not damaged. If there is a fault, please refer to ”Fault Tracing the Cables and Connectors”. NOTICE! Some fault codes become inactive when the engine is stopped. Start the engine to check whether the fault code is still inactive with the engine running.
•
After an action with the connector Put the connector* back. Check if the fault code becomes inactive. If the fault remains, measure the cables and sensors to check them, as instructed. NOTICE! * No grease in the connector.
Problems in identifying the engine control unit (MID 128) In normal cases, VODIA identifies the engine control unit (MID 128) and the PCU (MID 187) automatically when the choice of engine installation is done. The HCU must be in service mode to allow it to be identified. If VODIA is not able to identify the engine control unit (MID 128), this will not be visible under ”Vehicle information”. NOTICE! If the engine control unit has not been identified, it can not be programmed.
Stop The system can not be shut down although the starter key is turned to position 0. This can be caused by a short circuit in the cables between the HCU and the key switch, by a short circuit in the key switch or a fault in the stop/start panel. Shut the system off with the AUX stop button. The starter motor is activated with the ignition on. If the starter motor is activated as soon as the switch is turned, the diode in the key switch cable harness might be short circuited. Fault trace the diode in accordance with the ”Checking the key switch diode” section.
One reason why identification can not be done is that the PCU contains the wrong engine software or that the J1708A and J1708B data buses between the engine control unit and the PCU are short circuited to each other. In this case, Vodia can not identify a control unit.

Circuit description
a
A water-in-fuel monitor is located in the water separator beneath the fuel filter. The monitor senses the resistance between two copper pins. The copper pins are in contact with the fuel. When there is no water in the fuel the resistance between the pins is very high. If any water is present in the fuel, the resistance falls. At a threshold resistance (water detected) the monitor output signal (yellow cable) to engine control unit pin 8 is reduced to zero by a transistor. Engine control unit pins 57 and 60 supply the 3-pin monitor with battery voltage. The monitor is connected to the battery negative terminal via engine control unit pin 10.

Circuit description D9CC, D13, D16 The oil temperature and oil level sensor is a combined sensor. The oil level sensor is supplied by a pulse of approximately 250 mA for approx 600 ms, and the voltage drop over the sensor is read off three times during this interval. In order to obtain oil level, oil temperature must be used as a reference because oil level sensor output changes depending on oil temperature.

Air inlet pressure/intake manifold temperature
D11, D13, D16 a
The intake manifold temperature sensor comprises a thermistor that forms a closed circuit with an internal resistor in the engine control unit (EMS2). Thermistor resistance changes non-linearly depending on intake manifold temperature. EMS2 supplies the circuit with a reference voltage of +5 volts. EMS2 measures the voltage drop across the thermistor via EMS2 pins 47 and 11. Sensor pin 1 is connected to battery negative via EMS2 pin 11. When intake manifold temperature is cold thermistor resistance is high and EMS2 detects a high voltage drop. As intake manifold temperature rises thermistor resistance falls and voltage drop is reduced. Refer to the Resistance/temperature table in this fault code chapter.

The coolant temperature sensor consists of a thermistor that forms a closed circuit with the engine control unit. A thermistor characteristic is that its resistance changes non-linearly in relation to the temperature of the medium it measures. Engine control unit B, pin 27, supplies sensor pin 1 with a reference voltage of +5 volts. Sensor pin 2 is connected to battery negative via engine control unit connector pin 18. When the coolant is cold thermistor resistance is high and the control unit senses a voltage close to the reference level. As coolant temperature rises thermistor resistance falls and the voltage drop is reduced. Refer to the resistance/temperature table.

Oil temperature sensor
Circuit description The oil temperature sensor is a combined sensor that also measures oil pressure. A thermistor characteristic is that its resistance changes non-linearly in relation to the temperature of the medium it measures. If the oil in the engine is cold, thermistor resistance is high. If the oil temperature rises, thermistor resistance drops. The voltage drop across the thermistor changes as oil temperature changes. The voltage drop is detected via pin 31 on the engine control unit. Engine control unit pin 7 supplies sensor pin 1 with +5 volts. Sensor pin 4 is connected to battery negative via engine control unit connector pin 11. Refer to the "resistance/temperature, engine" table.

Circuit description D13
The oil temperature and oil level sensor is a combined sensor. The oil temperature sensor comprises a thermistor that forms a closed circuit with an internal resistor in the EMS. Thermistor resistance changes according to a non-linear characteristic depending on oil temperature. The EMS supplies the circuit with a reference voltage of +5 V via pin A31. The EMS measures the voltage drop across the thermistor via pin B10 and A31 for D16 and pin A11 and A31 for D13. Sensor pin 4 is connected to battery negative via the EMS. When oil temperature is cold thermistor resistance is high and the EMS detects a high voltage drop. As coolant temperature rises thermistor resistance falls and the voltage drop is reduced.

Circuit description There is a valve in the oil filter bracket that opens and closes piston cooling oil supply depending on oil pressure. If oil pressure is below 240 kPa (D12) or 300 kPa (D16) the valve closes piston cooling oil supply. Piston cooling pressure is overseen by a pressure monitor. The monitor output signal – engine control unit pin 1 – can only have one of two distinct potentials, high or low. The monitor is supplied with power by engine control unit pin 10. A specified pressure limit of 150 kPa determines when the monitor switches potential. Monitor potential is low when piston cooling pressure exceeds this value. At idle the monitor may have high potential without any fault code being triggered.

•
Poor compression.
•
Fault in injector.
•
Asymmetric engine load*.
* If the engine is asymmetrically loaded and a fault code is triggered it is not possible to remedy the fault code as there is no mechanical fault. At idle the engine control unit will attempt to compensate for the uneven running by supplying more or less fuel to the injectors, so-called cylinder balancing. If the asymmetric load is too great engine control unit compensation will be insufficient. The engine will run unevenly and a fault code will be triggered. Suitable action:
1 Do a compression test and a cylinder balance test, using VODIA, to localize the fault source. 2 Check the injector by changing it. The injectors are manufactured with tolerance specifications. When an injector is changed an injector trimming procedure must be carried out. The trim value is specified as a 6-character code on the injector's electrical connector. The trim value is entered in VODIA only for the cylinder that has the replacement unit injector.

The camshaft sensor is an inductive sensor. The camshaft sensor is used in the first instance to determine which cylinder is next in line for injection. A reluctor wheel installed on the camshaft is used to determine which cylinder is next in line for injection. The reluctor wheel has 7 teeth, one for each cylinder plus an extra tooth for cylinder 1. When the camshaft and reluctor wheel rotates, impulses are generated in the sensor. The impulses generate a pulsed signal in the sensor which the engine control unit uses to determine which cylinder is next in line for injection.

The flywheel sensor is an inductive sensor. The flywheel sensor is used for monitoring engine rpm It is also used to measure cylinder acceleration. The flywheel has 3 x 18 depressions per revolution. These depressions are detected by the flywheel sensor which generates a pulsed signal. The engine control unit uses the pulsed signal to determine flywheel rpm. Two cylinders each share one flywheel depression sector (cylinders 1 and 6, 2 and 5, 3 and 4). This means that it is not possible to know which cylinder is in line for injection, without the camshaft sensor.

An electronically governed control valve is used by the engine control unit to control the level of air pressure supplied to the wastegate valve. When air pressure supplied to the wastegate valve by the control valve increases, the valve opens more. When the wastegate valve is fully open, exhaust gas flow to the exhaust turbine is at its lowest.

As soon as the power module receives power from the primary battery or the secondary battery, with main battery switches on, the 30 supply output is powered (connected to key switch and MCC / EVC). If the power module receives a +15 ignition signal it will activate EMS2 and extra power outputs (engine mounted instruments such as EasyLink, External stop and Water in fuel).

Injector trim The electronic trimming strategy is used to ensure that all injectors work with nominal injection times and fuel quantities. This is achieved by adjusting the beginning and end of the electronic wave pattern for every actuator. In this way compensation is made for the spread of activation and deactivation times of the two actuators in each injector, and deviations in fuel delivery due to variations between the different nozzle flows are also corrected. NOTICE! Write down the new injector codes before installation. The codes comprise 6 characters on 2-pin injectors and are located on the injector's electrical connector below the SN number. On 4 pin injectors the code comprises 9 characters located on the injector's electrical connector below the SN number.

39-0 General Adjustment parameters for lowspeed or trolling function The lowspeed or trolling function can be fine-tuned using VODIA. Go into “parameter programming” and adjust the parameters given below. For Volvo Penta Lowspeed FYE (Maximum slip factor for VP Lowspeed - gives the value for maximum speed reduction). Enter a value within the range specified for the parameter. FYF (Upper lever limit for slip function at forward specifies within how large a part of the lever movement the function will be active when forward gear has been selected). Enter a value within the range specified for the parameter. FYG (Upper lever limit for slip function at reverse specifies the amount of lever travel in which the low speed function is active, when reverse gear has been selected). Enter a value within the range specified for the parameter. For Volvo Penta Trolling HAZ (Maximum slip factor for VP Trolling - specifies the value for maximum speed reduction). Enter a value within the range specified for the parameter.
