WARNING During rapid charging of batteries, always remove the cell caps. During charging, an explosive mixture of oxygen and hydrogen is formed. A short-circuit, open flame or spark near the battery can cause a powerful explosion. Always turn off the charging current before disconnecting the charging clamps. Ventilate well, especially if the battery is being charged in a confined area.

The battery electrolyte contains corrosive sulphuric acid. Remove spilled electrolyte from the skin immediately. Wash with soap and plenty of water. If electrolyte has splashed into the eyes or on any other sensitive body part, rinse immediately with plenty of water and contact a physician immediately.

WARNING The batteries could explode due to the current surge if a fully charged battery is connected to a completely discharged battery. Since the batteries contain sulphuric acid, this could result in personal injuries.

WARNING Never charge a frozen battery. Explosion hazard! 

Never disconnect the main electric current or disconnect battery cables when the engine is running.

Figure 1 

The battery's minus connection must always be disconnected before removing or installing components and connections in the electrical system. NOTE! Incorrect handling may cause damage to, for example, control unit/ECU which results in downtime.

Figure 2   

Fully charged batteries must be used when checking the electrical system. If the batteries are not fully charged, charge them or replace with new batteries. During battery charging, the battery terminal cables must always be disconnected from the battery. When changing batteries connected in series, the batteries should have the same capacity (for example, 150 Ah). The batteries should be of the same age (equally good). The reason for this is that the charging current required to give the battery a certain charge varies with the age of the battery.



Only batteries may be used as assistant starting devices. An auxiliary starter unit and/or batteries connected in series to assist when starting may result in high (excess) voltage and can seriously damage electronic/electric components.

Electronic control system, description General vehicle electronics The new vehicle electronics, based on the data bus principle, lay the foundation for being able to proceed with development and design of the system. The improved diagnostic possibility makes for easier, faster and safer troubleshooting. Further, the operator’s demand for information is fulfilled, through added functionality of the instrument, with the possibility of obtaining read-outs of important information from the different electronic control units. Conventional control system

Figure 1 Conventional system with connections In principle, a conventional control system is designed in such a way that one or several of the vehicle’s components have their own control unit that receives signals from various sensors (earlier generations of excavators have only been equipped with a vehicle control system). Each control unit serves its own component and sends signals to the other control units and operating controls by way of electrical cabling. For example, an engine control unit that receives signals from various sensors on the engine and eventually from other control units on the vehicle. Engine speed control switch position, travel speed signal, etc. are sent to the engine control unit by way of cabling from different sensors and switches. There must be one or several connections (sockets) in the system, where tools can be plugged in for programming and for read-out of information and eventual error codes. In the future, the individual machine components will require several control units per component, and machine electronics will become increasingly complex. In time, this will limit the possibilities for a conventional control system to handle its task. Data bus system

Figure 2 All control units (ECU) are connected via data buses Volvo CE’s new vehicle electronics are based on the principle that all communication between the control units in the system takes place by way of two data buses. The main vehicle components are equipped with their own control units, that are connected to the buses for communication with each other. Simplified, this can be described as follows; when the operator wants to increase speed, a signal is sent from the engine speed control switch or pedal (T mode) to the vehicle control unit and, through a data bus, the signal is transmitted to the engine control unit. The engine control unit communicates with the other control units by way of the buses, either by asking a question or by receiving direct communication that all is in order to be able to "execute the command". If a malfunction should appear in a system, a signal is sent out on the information bus, which makes it possible to read the information, either on the operator’s instrument, with the Contronic service display unit, or with a VCADS Pro connected to the service connection. The data bus system provides a very flexible solution with extensive add-on possibilities.

General The vehicle electronics are based on the principle that all communication between control units in the system takes place via two data buses. The machine's four control units are connected to the buses to be able to communicate with each other. Communication between the different control units as well as reporting from control units to service sockets takes place on data buses CAN/J1939 and J1708/J1587. The buses adhere to SAE-standard and consist of two pair-twisted cables. The purpose of the twisting is to protect the bus from electrical interference. If a malfunction should occur in the system, a signal is sent on the information bus, making it possible to read the information, either on the operator's instruments or via the service display unit or VCADS Pro. The figure shows the principle for how the control units and service sockets are connected to the buses. CAN/J1939 control bus The system's control signals are sent via this bus. The control bus is very fast, which is a requirement for control of the whole system to function and quickly adapt to varying conditions.

The main communication alternative is the CAN/J1939 bus. However, for E–ECU, some control data is only sent on the J1708/J1587 bus. J1708/J1587 information bus The information bus is connected to the control units and service socket. Information and diagnostic signals are sent on this bus. In addition, some control data is sent from the engine control unit via this bus. The bus also functions as "back-up" for the control bus if it doesn't work for some reason. Via the information bus, the system's status is updated continuously and is available for reading. By connecting the service display unit or VCADS Pro to service sockets, it's possible to read error codes, perform tests, empty logged information, upload parameters and upload software.

Data buses, function

Figure 1 The oscilloscope display shows voltage level on the data bus Data buses constitute a way to transmit information between different components. In conventional systems, primarily analogue signals have been used. Analogue signals mean that different voltage levels represent different values. A simplified example of analogue signals: 1 Volt = 10 °C (50 °F), 2 Volt = 20 °C (68 °F), 3 Volt = 30 °C (86 °F), etc. Data buses use digital communication. This means that voltage only varies between two different values, either "high" or "low". By combining these high and low signals, it is possible to describe different values. The illustration shows an oscilloscope display where voltage is measured on the data bus. As is evident in the illustration, the greatest part of the time is "silent" on the bus, but every so often, a number of fast impulses can be seen. A collection of impulses is called a message. The enlarged oscilloscope display shows a message that consists of a combination of high and low voltage levels. Messages and information content

Figure 2 Information content The different voltage levels are represented by the different digits in the binary number system. The binary number system only has two digits, ones and zeros. The ones normally represent a high voltage, and the zeros represent a low voltage. Note in the example from the oscilloscope display, in this case, ones are shown as low voltage and zeros are shown as high voltage, and this depends on which bus and on which cables the measurement is performed. Every individual binary digit is called a "bit". This message consists of four groups of binary digits. The start and stop bits are shaded since they do not contain any information. Each group constitutes 1 Byte = 8 bits. One Byte can represent a value between 0 (0+0+0+0+0+0+0+0) and 255 (128+64 +32+16+8+4+2+1). Figure shows the information content in the four different parts of the message. The square in the illustration shows the different binary and decimal values that the information in the message contains. NOTE! The information is sent out on the bus with the "lowest" digit first of the binary digits. The normal way of noting binary numbers is shown in the square in the illustration.

Figure 3 Voltage levels binary data The purpose of the start and stop bits is only to function as markers for where the group begins and ends. In figure, only the start and stop bits are marked, the other information is shaded. Identification number

Instrument control unit I-ECU, function description

Figure 1 I-ECU, position The Instrument electronic control unit (I-ECU) is located in the cab on the right side of the steering wheel. The I-ECU displays the information received from the sensors and switches of the machine to alert the operator of any abnormality. All control lamps should be checked daily and replaced if burnt-out because the indicators alert the operator of a failure in the machine. The I-ECU contains a coolant temperature gauge, fuel gauge and alert indicators to show machine conditions.

Figure 2 I-ECU The I-ECU receives information on the data bus. The information is processed and presented on the information display. Functions

 

The engine speed and the actual work mode (P-, T-, W-mode) are shown on the display window. Values for battery voltage, hammer operating hour (option) and error codes can also be shown on the display window and in some cases changed.

I-ECU, checking Before engine starting  

Before starting the engine, if you turn the start switch to the ON position all lamps are turned ON for 3 seconds. At the same time the buzzer is operated 2 times with the cycle of 1.0 second ON and 1.0 second OFF. Check if all indicator lights come on, and if not, check for burnt-out light bulbs, and the plug–in connectors (connector A, B) of the printed circuit board.

After engine starting   



Before start–up, the battery charge warning lamp and engine oil pressure warning lamp remain ON. Once the engine starts, the above indicators should go out. When the engine is run at very low speed, the battery charge warning lamp may remain ON. If this happens, increase the engine speed, and check if the light goes off. If it remains ON, it is necessary to check the charging system. If the engine oil pressure warning lamp remains ON for 2 ~ 3 seconds after the engine is running, stop the engine and check the engine lubricating system.

Figure 1 Engine control unit of D10B and D12C engine

Figure 2 Engine control unit of D12D engine The engine’s unit injectors are controlled entirely by electronics, with regards to injected fuel amount and injection timing. The system is called EMS (Engine Management System). This section describes, in brief, the parts that are mounted on the engine. There are a number of other parts that affect the system, for example, the engine speed sensor. The central part in the system, the control unit is located on the left side of the engine. All cable connections for the engine sensors have connectors with DIN-standard and are gathered in a so-called cable box.

Figure 3 Engine control unit, position Control unit The control unit is the central part of the injection system. It is located on the left side of the engine and mounted in brackets with rubber dampers. The control unit receives continuous information from V-ECU (requested target engine speed) and a number of sensors on the engine, and calculates the fuel amount and at what time the fuel should be injected into the cylinders. The control signals to the unit injectors run through electrical cabling to the unit injector fuel valves. Since the control unit, through the flywheel sensor, senses the engine speed and also differences in engine speed during the revolution, the control unit makes sure that each unit injector receives exactly the right amount of fuel. The control unit stores information if a malfunction should occur, or if something in the system is abnormal. Even malfunctions that occur sporadically are stored in the control unit and can thus be traced at a later time. Functions

Troubleshooting, general WARNING During all troubleshooting and work on the electrical system, follow all the safety instructions in the section Safety. The “Troubleshooting” section describes how troubleshooting is performed for symptoms and malfunction related to the machine’s electrical system. There is also information about the functions of the different electrical components, measuring values and possible malfunction detection. The starting point of all troubleshooting is that there is some type of trouble symptom or malfunction. Malfunctions can be indicated by:     

red central warning flashes buzzer sounds amber flashes error codes shown on the machine display unit detection of a malfunction symptom

Depending on how the malfunction is indicated, a number of different actions should be performed.  

In case that generate: Flashing amber warning - investigate the cause at the next stop. In cases that generate: Flashing red central warning - stop the machine immediately and investigate the malfunction cause!

When a malfunction is suspected or has been confirmed, it is important to identify the cause as soon as possible. The first step in troubleshooting is to gather information from the operator concerning the malfunction symptoms. Then, attempt to pin-point the cause by performing checks in a certain order. The different checking steps are:     

Check error codes Check parameters Perform basic check Troubleshoot using a symptom guide Performance check

In order to make troubleshooting easier and more effective, a number of assistant devices are available. For example, VCADS Pro service tool and contronics service display unit.

The basis for all troubleshooting is some type of symptom or malfunction. In order to arrive at a basis for troubleshooting, a collection of data concentrated around the symptom/function disruption should be done. A checklist for collecting this data is also available in the form of " Collection of basis data". The error codes give a clear indication of what has caused the symptom or malfunction. Therefore, read out error codes before any troubleshooting is started. Check if there are any error codes generated in the machine’s control units. The error codes can be read from the contronics service display unit or using VCADS Pro. A. B. C.

D.

3. 4.

If an error code has been generated, troubleshooting should be performed according to the reference from "Error code, troubleshooting". The existing error codes are noted and then compared to any new or reappearing error code. When the problem has been solved, the error codes should be erased. In order to confirm that the malfunction has been corrected, the machine components/functions in question must be activated so that the control unit can perform a new self-diagnosis, and generate eventual new or reappearing error codes. The error codes are read to confirm that the symptom/malfunction has been corrected and to make sure that no subsequent problems have occurred in connection with repair work.

Check that the parameters are set correctly. A list of all parameters and parameter values are found in the form of a parameter list. The basic check is divided into three tests, which should be performed in the order that they are presented. See section 2, Basic check engine.

Collection of basic data General Collection of basic data is the first step in all troubleshooting. This is done to quickly get an improved overall picture of how the problem shows up. In addition to information about the excavator and customer, it is important to gather as much information as possible with regards to the circumstances and sequence of events when the malfunction occurred. Often, the operator can provide valuable information regarding the circumstances when the malfunction occurred. The operator is almost always the one who notices a malfunction first. Since it is seldom possible to recreate the experienced problems, without having exactly the same conditions, the information from the operator is of great importance in order to be able to make correct evaluations for continued troubleshooting. Interview the operator using the following questions. Note the answers in writing and keep them together with the work order. The operator should be able to answer the following questions: General data    

Customer information Information about the dealer Operator Machine specifications:       



Machine Serial number Operating hours Engine type Engine number Model year Delivery date

Have any error codes been generated?

Description of malfunction or symptom         

Describe the malfunction. When did the malfunction occur? How was the malfunction noticed and what happened just before it was noticed? Does the malfunction reappear? How often does the malfunction occur? For how long does the malfunction last when it occurs? Does the malfunction always occur during the same conditions, and what are those conditions? Does the operator have an idea of what may be the probable cause of the malfunction? Does the problem still exist?

Service Information Document Title: Function Group: Checking electrical cabling 302 and connectors

Information Type: Service Information

Profile: EXC, EC360B LC [GB]

Checking electrical cabling and connectors General When troubleshooting the electrical system, checking of electrical cabling and connectors is important, since causes of a malfunction often can be attributed to loose connections or damaged cabling. NOTE! Before troubleshooting of cabling and connectors, the affected circuit fuses should be checked. Checking is performed using multi-meter, multi-pin breaker box and cable adapters. See "Special tools for troubleshooting". To find suitable checking points, see wiring diagrams. NOTE! The following should be observed when working on electrical systems. 

 

After dismantling connectors, certain connectors should have, for example, contact grease applied to reduce the risk of oxidation and loose connections. See installation information for respective component under heading "Components, troubleshooting and specifications". Do not perform measurements by penetrating the cable insulation. Work carefully when measuring with test cord in the connectors so that connector pins and sockets are not damaged or expanded.

Connectors and cable terminals, checking When measuring and checking where connectors are dismantled, the connectors and cable terminals should be checked visually according to the following. 1. 2.

3.

Look for oxidation on the cable terminals. Oxidation may impair contact. Check that the cable terminals are not damaged, that they are correctly inserted in the insulator, and that the electrical cabling is securely connected in the cable terminals.

Figure 1 Connector, checking mechanical contact Check that the cable terminals have good mechanical contact. Use a test cable terminal when checking.

Figure 2 Connector engine ECU, checking mechanical contact NOTE! For engine ECU connector, a special gauge is used. Open circuit, checking Open circuits in electrical cabling and cable harnesses are caused by, for example, chafing, crushing, or pulling forces. Check for open circuits according to the following. 1.

2.

3.

Unplug the connectors in question at both ends of the cable harness.

Figure 3 Checking for open circuit with resistance measurement Measure the resistance between the ends of the electrical cabling. The resistance should be ≈0 Ω for cabling without an open circuit.

Figure 4 Shaking and pulling to find open circuit Shake the cable harness and pull lightly on the connectors while measuring to find eventual open circuits.

Short-circuited to frame ground, checking Short-circuited between voltage-conducting cabling and frame ground often leads to a fuse blowing. Checking of shortcircuited to frame ground is performed according to the following. 1.

Key position to ON.

2. 3. 4.

Figure 5 Checking short-circuiting to frame ground with resistance measurement Activate all switches and sensors in the circuit and check if any fuses blow. Unplug all connectors in question for the components in the circuit so that these do not affect measurements. Measure resistance between the electrical cabling and frame ground. The resistance should be ∞ Ω for electrical cabling without short-circuit to frame ground.

Figure 6 Principle for checking short-circuiting to frame ground by measuring Short-circuited to voltage, checking Short-circuited between a cable and voltage conducting cable with resistance often leads to a blown fuse when the cable is supplied with voltage. 1.

2.

Measure voltage with a multi-meter at suitable points in the circuit at the same time as the switch and sensor are activated. The voltage value depends on several parameters. See wiring diagram, signal description and component information.

Figure 7 Checking short-circuiting to voltage conducting cable with resistance measurement Unplug the connectors in question at both ends of the cable harness. Measure resistance between electrical cabling that may be short-circuited to each other. Resistance should be ∞ Ω for cabling not short-circuited to each other.

Figure 8 Principle for checking short-circuiting to voltage by measuring Connector resistance and oxidation, checking Loose connections or temporary, repeated malfunctions can be difficult to troubleshooting and often occur due to oxidation, vibrations or by poorly connected cables. Moisture in the connectors may also be a cause of contact problems, such as damaged pins or sockets. The resistance in the connectors and cabling should be ≈0 Ω. Some resistance may be present due to oxidation on the cable terminals. If too much connector resistance is encountered, there will be disruptions of the function. The amplitude of the resistance may vary, without any disruptions occurring, depending on how great the load is in the circuit.

Figure 9 Shaking and pulling on the connectors NOTE! Shake the cable harness and pull lightly on the connectors while measuring to find eventual loose connections. Pins and sockets, cleaning 1. 2.

Turn OFF the master switch. Blow clean the connectors with compressed air.

3. 4.

Figure 10 Connector, spraying with contact spray Spray the connectors with contact spray. Again, blow clean the connectors with compressed air.

In service tool VCADS Pro, error codes of the SAE-type are used. SAE-error codes are designed with identification numbers under, for example, MID, PID and FMI. Abbreviation

Explanation

MID

Message Identification D escription (identification of control unit). There is a unique number for each control unit.

PID

Parameter Identification D escription (identification of parameter/value). There is a unique number for each parameter.

PPID

Proprietary Parameter I dentification Description (Volvo-uniqueidentification of parameter / value). There is a Volvo-unique number for each parameter.

SID

Subsystem Identification D escription (identification of component). The SID-number depends on which control unit (MID) that they are sent from. Each control unit has it’s own number series for SID. The exceptions are SID-numbers 151-255 which are general for all systems.

FMI

Failure Mode I dentifier (identification of failure type).

Troubleshooting information in this service manual is based on error codes from Volvo excavators. When reading error codes from VCADS Pro, the SAE-error codes must be converted to Volvo excavator error codes for further troubleshooting. The following are conversion tables from SAE-error codes to Volvo excavator error codes.

parameters Incorrectly set parameters may cause malfunction symptoms. Check the parameter values so that these are reasonable by comparing them to the correct values and limit values. Use VCADS Pro to check the program parameters. There are two types of parameters that can be programmed, machine parameters and customer parameters. Machine parameters are of the accessory type or legal requirements, and requires on-line connection to the Volvo data base VDA (Vehicle Data Administration) to enable programming. Customer parameters do not require on-line connection, they can be programmed directly. Parameter list The tables are not final, they may be updated as new functions are introduced.

NOTICE Take great care when attaching test cables to connectors so as not to damage or expand the pins and sleeves.

NOTICE When measuring directly in connectors, good lighting and access is required to avoid short-circuiting between the leads. Carefully follow all instructions in Electrical system, work instructions. See also 302 Special tools for troubleshooting and 302 Component fault diagnosis, general. Active testing of component and circuit Active testing implies testing of a closed circuit. The adapter cable is connected between the cable harness and the component. Tools: 302 Adapter cable 999 8534, 302 Multimeter 981 2519

Profile: EXC, EC330B LC, EC360B LC [GB] Go back to Index Page

Error code information, general An error code is generated when the system detects an error on input to / output from a control unit (ECU). This occurs when the signal to / from a component is outside the range that has been defined as the signal’s limit values. The machine’s control units have integrated diagnostic programs which monitor input and output signals for components. All control units can generate error codes. NOTE! An error code indicates that there is an error somewhere in the circuit that is connected to the input / output. That is, component, cable or connector. The following describes which error codes can be generated, brief information about the error codes and references to troubleshooting information.

Figure 1 Error code of machine display unit (MDU), power shift proportional valve error General The SAE-codes are generated automatically by the electronic controllers. The SAE-code is generated according to SAEstandards and are given a designation depending on which control unit (MID) that generates the SAE-code, which component (PID) it applies to, as well as what type of error / malfunction (FMI) that the control unit has detected. Thus, that is the appearance of the SAE-code which is read by the service tool VCADS Pro. The SAE-code which is generated by the electronic controllers and can be read with VCADS Pro, is converted in the software to VOLVO EXCAVATOR error codes. Thus, the SAE-code generated by the electronics , for example, MID187 PPID1190 FMI3. The error code for the above example is ER31 - 03, which means that the control unit detects that the power shift proportional valve is giving a voltage that is high, but machine display unit (MDU) only displayed ER31. Control units The control units generate SAE-codes according to how they perceive the signals from / to components. This means that an open circuit in a signal line (from “5 V sensor”) does not always has to be given an SAE-code with FMI 04 (low voltage). The reason for this is the design of the control units, which sometimes have inputs connected to voltage, and sometimes ground. For this reason, an open circuit in a signal line, connected to voltage in the control unit, can give an SAE-code which ends with FMI 03 (high voltage). The above example applies to inputs that read off voltage. For inputs / outputs that read off current, open circuits give low current, short-circuiting to ground gives high current, etc. Each component can have max. three error codes. For this reason, FMI 11 (other error) is given for the errors that are not included in the interpretation of the first two FMI’s for each component. Example of error code interpretation

Figure 2 Input connected to ground (GND) FMI 04 = Low voltage Open circuit in a signal line, input connected to ground. Gives FMI 04 (low voltage). This FMI can be generated even when the signal line is intact, but 5 V supply to the component is below 5 V (for example, voltage drop due to loose connection or open circuit in supply cable). An open circuit in the input (when connected to ground) on the control unit also gives this FMI.

Figure 3 Input connected to voltage (+DC) FMI 03 = High voltage Open circuit in a signal line, input connected to voltage. Gives FMI 03 (high voltage). This FMI can be generated even when the signal line is intact, but 5 V supply to the component exceeds 5 V (for example, short-circuiting to higher voltage). An open circuit in the input (when connected to voltage) on the control unit also gives this FMI.

Components, troubleshooting and specifications WARNING During all troubleshooting and work on the electrical system, follow all the safety instructions in the section Safety. NOTE! Checking of electrical cabling and connectors is used to check short-circuiting, open circuits and loose connections as a first action before components are checked.

Contact / cable defects are more common than component malfunction. Therefore, always check the connector and cabling before checking the component in question.

See "Checking electrical cabling and connectors". Measuring, general Measurements for checking components and cabling should be performed when an error code for component has been generated. Measurements are performed to check component, cabling, output signals from ECU’s and frame ground connections. NOTE! Resistance measurement is an uncertain method, and that is the reason behind only a two-digit accuracy for resistance values. If possible, use voltage measurement. The following is a description of troubleshooting on a component and the connected cabling. Component troubleshooting, description

Battery, description The battery consists of two 12 V batteries connected in series, which together give 24 V. The batteries are used to start the engine, supply the current to the electrical components and store the current from the alternator. The batteries should be in good condition when troubleshooting the electrical system. If needed, charge the batteries with a battery charger. If the batteries do not take a charge, check the electrolyte in the battery cell.

WARNING If a tool touches a cable connected between the positive terminal and the chassis, there is danger that it will cause sparks. Battery post clamps must be tightly connected. If loosely connected, the terminal may burn or be eroded by sparks caused by defective contact. Battery acid can burn or blind you. If acid gets on your skin or in your eyes, immediately wash with plenty of clean water and consult a doctor immediately. NOTE! When removing the battery, first disconnect the cable with the black tube from the ground (normally, from the negative (–) terminal). NOTE! Battery power may be lowered under severe cold weather. In this case, warm up the batteries and start the engine.

Battery, charging WARNING During battery charging, hydrogen gas is formed. Hydrogen gas is flammable and may be explosive. A short-circuit, open flame or spark near the battery can cause a powerful explosion. Therefore, ventilate well. Never smoke near batteries. Op nbr 31104

1. Batteries must only be charged using a battery charger. 2. Check the battery terminal connections and make sure that they are adequately tightened and free from corrosion and dirt. 3. Check the battery voltage when the batteries are at rest, that is, before starting. Each battery must be at least halfcharged. NOTE! Always disconnect the electric power to the battery charger before the charging clamps are removed.

Battery, storage Batteries gradually lose their charge through self-discharge, which is dependent on storage temperature and charge level. A fully charged battery stored in a cool place loses insignificant capacity in a three-month period. A battery that is partially charged and/or is stored at room temperature loses capacity faster. Therefore, always store batteries fully charged and as cool as possible, however, not at freezing temperature. During longterm storage, the battery should be checked periodically and trickle-charged if needed.

Charging, description When the starter motor is activated and the engine starts:    

The alternator generates current to activate all the electrical systems, and the extra current charges the battery. The current flows to the safety start relay to cut off the operation of starter motor and prevent accidentally reengaging the starter. After the engine starting, the battery charge warning lamp is turned off because the signal from "L" goes to the VECU and the V-ECU communicates with I-ECU about the charging status. The current flows to the hour meter, which operates in the start switch ON position.

Starting operation Power supply 

The negative terminal (–) of battery is grounded to the machine. When the master switch is in the OFF position, the power supply is disconnected.

If the master switch is turned to the ON position and the start switch to the OFF position, the current flows in the following circuits.  

Battery (+) → Starter motor terminal (B+) → Battery relay Battery (+) → Slow blow fuse (FU51, 40A) → 



Fuse box (FU16, 15A) → Start switch terminal (B+)

Battery (+) → Slow blow fuse (FU50, 40A) →      

Fuse (FU17, 5A) → Room lamp switch (SW3503) Fuse (FU18, 10A) → DC-DC converter → Cassette & radio Fuse (FU19, 20A) → Air conditioner relay Fuse (FU20, 10A) → DC-DC converter → Power socket (12V) Fuse(FU21, 15A) → Fuel filler pump (option) Auto greasing controller (option)

When the start switch is turned to the ON position, current flows in the following circuits. 

Start switch terminal (B+) → ACC terminal →    



V-ECU Fuse (FU1, 10A) → Instrument panel Air conditioner switch EMS Power relay

Start switch terminal (B+) → BR terminal → Battery relay coil → Ground

When the battery relay is operated: 

Battery relay  

Safety start relay Slow blow fuse (80A)  



Alternator B+ terminal. So, the current flows to the fuse box, and all electrical systems can be used.

Fuse box (FU1, 10A) → Battery charge warning lamp on the Instrument panel→ Alternator terminal D+→ Field coil → regulator IC → Ground. So the low voltage warning lamp comes on and excites the alternator.

Engine starting If the start switch is turned to the START position, the current flows in the following circuits. 

Start switch terminal (B+)

 

Terminal R2 → V-ECU(JB2) Terminal C  

Safety start relay pin 1 The safety start relay is activated.

When safety start relay is operated: 

Battery relay → Safety start relay → So, the current flows to the starter motor terminal S to rotate the starter motor and the engine starts.

Starter safety lockout If the start switch is in the START position continuously:  

Alternator terminal D+→ current flows to the safety start relay pin 2 and the safety start relay is cut off. Therefore, the starter motor stops. While the engine is running, the starter motor can not engage even if the start switch is turned to the START position.

Stop 

If the start switch is released, it automatically returns to the ON position. When the start switch is turned to the OFF position, the current to the EMS power cut off relay from start switch terminal ACC is shut off. Request engine stop from V-ECU is sent to E-ECU until engine is stopped.

The V-ECU releases the PEAK load on the electrical system when the engine stops. 

V-ECU → Diode → so, the electric current flows to the battery relay coil to temporarily activate the battery relay. At this time, the V-ECU sets the engine speed into the low idling condition to reduce the load, and then cuts off the battery relay.

Profile: EXC, EC360B LC [GB]

Fuel/Coolant temperature sensor, description

Figure 1 Coolant/fuel temperature sensor The coolant is also supplied to the engine integrated oil cooler. Thus the coolant temperature sensor indirectly monitors the engine oil temperature at the same time so that usually separate engine oil temperature sensor will not be necessary. The temperature sensor senses temperature by the resistance variation according to temperature changes within the thermistor. The sensor provides information necessary to E-ECU.

Figure 2 Coolant temperature sensor location, engine flywheel side view 1.

Coolant temperature sensor

As the fuel temperature increases, the engine performance drops. This is due to the fact that the thickness of the fuel decreases, and there is an increase in leakage losses in the injection pumps. This sensor monitors the fuel temperature, and

E-ECU will make a corresponding control adjustment to compensate the fuel amount.

Instrument panel, checking Before engine starting  

Before starting the engine, if you turn the start switch to the ON position all lamps are turned ON for 3 seconds. At the same time the buzzer is operated 2 times with the cycle of 1.0 second ON and 1.0 second OFF. Check if all indicator lights come on, and if not, check for burnt-out light bulbs, and the plug–in connectors (connector A, B) of the printed circuit board.

After engine starting   



Before start–up, the battery charge warning lamp and engine oil pressure warning lamp remain ON. Once the engine starts, the above indicators should go out. When the engine is run at very low speed, the battery charge warning lamp may remain ON. If this happens, increase the engine speed, and check if the light goes off. If it remains ON, it is necessary to check the charging system. If the engine oil pressure warning lamp remains ON for 2 –3 seconds after the engine is running, stop the engine and check the engine lubricating system.
