This manual is part of the aids that the Technical Publications sector makes available to workshop technicians to allow the correct performance of maintenance and/or repair operations and it is also a good way to familiarise with the IVECO product.

The experience acquired over many years in servicing and in editing technical publications has led us to devote a special volume to the electric system fitted on the models in question, considering the particularity and complexity of the subject.

This manual is intended for people with professional preparation in the ”Vehicle Electrician” sector and at the same time avail of adequate and indispensable testing and/or measurement equipment for the main electrical ratings.

In drafting the texts and representing the graphics we have taken account of the particular necessities of the operator technician in some cases stating references or repeating certain diagrams in different places that may be obvious to a design engineer.

The completeness of the information given in the wiring diagrams, the size chosen and the ease with which they can be taken allow the repair operator to avail of all the information exactly where it is needed most, namely, on board the actual vehicle.

General cautions for electric/electronic components NEVER DISCONNECT THE BATTERIES OF THE SYSTEM OR OPEN THE KNIFE SWITCH WITH THE ENGINE RUNNING. DO NOT START THE ENGINE WITHOUT FIRSTLY CONNECTING THE BATTERIES PERMANENTLY. — Before doing any work on the vehicle chock the wheels appropriately.

— Starting from the engine compartment may only be carried out when the cab is firmly fastened on its maximum opening position with the handbrake engaged, gearbox in neutral and wheels chocked.

— Do not use quick chargers to start the engine. Starting must only be carried out with separate batteries or with the special trolley.

— Make sure that the bias of the battery terminals is correct when starting from an auxiliary trolley.

— The incorrect polarisation of the power voltage of electronic control units (for example incorrect polarisation of the batteries) may lead to their destruction.

— When needing to disconnect the batteries from the system, firstly always disconnect the frame earth cable from the negative terminal of the batteries.

— Before connecting the batteries to the system, make sure that it is well insulated.

— The incorrect bias of the supply voltage of electronic control modules (foe example incorrect battery bias) may lead to their breakage.

— When seeking a circuit failure insert a wander fuse between the negative terminal of the battery and the frame earth cable (main current switch on).

— Before removing electric and/or electronic components disconnect the earth cable from the negative terminal of the battery.

— Electrical measurements on electronic components must only be carried out with appropriate measuring equipment.

— Disconnect the batteries from the system when charging them with external equipment.

— Disconnect the external charging equipment from the mains before removing its grippers from the terminals of the batteries.

— Do not insert or remove the connector of electronic control units with the power on.

— With temperatures above 80 °C (drying ovens) remove the electronic control units.

— During electric welding work, disconnect the connectors of electronic control units.

— During connection, tighten the nuts of the connectors (temperature, pressure sensors, etc.) only with the specified tightening torque.

— Carefully make sure that the battery terminal polarity is correct before starting from an auxiliary trolley.

— Do not direct jets of water on fuseboxes and electrical equipment.

— Do not direct jets of water on the batteries.

Measurements in electronic control units, plug connections and electric connections to components may be carried out only on appropriate testing lines, with special plugs and sockets. Never use improper means such as metal wires, screwdrivers, clips or the like. In addition to the danger of a short circuit, damage to the plug connectors may also result and this would subsequently cause contact problems.

INTRODUCTION

CURSOR 8/10/13

Concept of earth and electromagnetic compatibility The electric system is traditionally a single-pole system. The body, the frame, the metal container of electromechanical components act as equipotential return conductor to the generator, as any point of their metal structure or any negative terminal not isolated is at the same reference potential or EARTH. This is why the earth has been chosen as reference to the whole system, conventionally giving it the value of zero.

Due to obvious reasons of construction, in the negative network of the system there are various earth points located on the vehicle in relation to the location of the components on the frame, engine or body.

On the other hand, ideally, all the equipment should be connected to only one earth point in order to provide them, particularly for electronic devices, a clearly defined earth reference.

For the above-mentioned reasons it is necessary to distinguish the supply earth or system earth, characterised by strong direct current intensity (> 1 A for electromechanical components), from the analogue earth, characterised by wave shapes at determinate frequencies and very low current intensity (mA, µA) of electronic systems.

The definition of signal earth or analogue earth depends on the sensitivity of the electronic systems to EMC (electromagnetic compatibility), as parasite signals emitted by the systems on board or outside the vehicle, induce failures and/or deterioration of the systems themselves.

In order to minimise both continuous and transient disturbance or interference generated by parasite radiations, it is of the utmost importance to always bear in mind that the satisfactory efficiency of the reference plane or system earth depends on the excellent conductivity characteristics (contact resistance tending towards zero) in each of its connection points.

Briefly, we can say that the earth understood as equipotential electrical conductor, i.e. as potential reference for all the electric/electronic components on board, is subdivided into system earth and analogue earth.

The system earth points are those foreseen by the Manufacturer and must, of course, be free of paint, oxidation, grease, dust, etc.

Should it be necessary to disconnect the earth cables from the frame, when restoring the connection it is necessary to completely remove the old conduction paint and coat with an even layer of paint BH44D which meets IVECO Standard 18-1705, proceeding as follows: 1° Remove the paint on both the frame and terminal side mechanically or using a suitable chemical product.

2° Brush on the paint, if in can, or spray.

3° Connect the earth cables within a maximum of 5 minutes from painting.

4° If a new earth contact is fitted, file around the terminal fastening hole to completely remove the anaphoretic paint of the frame creating a perfectly flat resting surface.

Practical advice The negative cables connected to an earth point must be as short as possible and connected to one another in a “star” connection, trying to tighten them neatly and adequately (Fig. I.4 ref. M).

Additionally, for electronic components the following instructions should absolutely be followed: — Electronic control units must be connected to the system earth when they have a metal container.

— The negative cables of control units must be connected to both a system earth point, for example the dashboard earth (avoiding “serial” or “chain” connections), and to the negative terminal of the battery/ies.

— Though they are not connected to the system earth/battery negative terminal, analogue earths (sensors) must be perfectly insulated. Therefore, particular care should be given to the parasite resistances of the terminals: oxidation, clinching defects, etc.

— The metal braiding of screened circuits must be in electrical contact in each of its ends with the components of the system.

— Only one end of the screening braid must be connected to the system earth.

— In the presence of connectors the unscreened section d, near them, should be as short as possible (Fig. I.5).

— The cables should be laid on parallel with the reference plane, i.e. as near as possible to the frame/body structure.

— Additional electromechanical systems should be carefully connected to the system earth and must not be set at the side of the cables of electronic components.

Concept of CAN LINE Over the past few years electronic systems on industrial vehicles have developed rapidly and they determine satisfactory operation of the vehicle.

What before was a complementary science has now become a key sector of technology. Currently electronic systems make the vehicle work and determine the effectiveness with which the single components interact with one another. Increasingly often we meet the term CAN used in this context.

The term CAN means Controller Area Network. This is a dedicated wiring that connects the control units of a vehicle (ECU) to one another, thereby creating a structure similar to a nervous system.

This system enables the instantaneous exchange of large quantities of data between the various electronic systems on board the vehicle.

It is a TWO-WAY communication mode that is becoming increasingly widespread in the field of vehicles, owing to the reduction of the number of leads and interferences.

The information travels respecting a protocol which defines the conversation modes: — Synchronisation of the information — Call and answer mode between the various systems — Identification and correction of any transmission errors — Etc.

Operating features To obtain new operating features it is important that the various electronic systems communicate with one another.

One of these operating features, for instance, is the reduction of torque during gearshifting, which is the result obtained from interaction of the engine and transmission control units.

The connection between the different control units may take place either grouping them in a single main unit (solution rejected due to the complexity of the management programme and because the system would be too rigid and expensive in the case of alterations and updates) or using a communication network capable of transferring the data quickly and reliably. Fast data transfer is fundamental for efficient management of vehicle driving, while reliability must be guaranteed for applications connected with safety (transmission, engine controls and control units) and there must not be any communication problems especially in the presence of electromagnetic influences.

About 60% of the problems concerning the electronics of a vehicle involve connection technology and can be identified in the corrosion of the contacts of a connector and in the connections of cables, wear of the insulating sheath or faulty assembly.

Another third of these problems is caused by operating faults in the sensors and actuators. Sing a lower quantity of cables and reducing the number of sensors, the stoppage time due to vehicles out of service will be minimised, resulting in lower operating costs. A wiring with less components will make it possible to diagnose the electronic system more easily.

The total length of the cables can reach several kilometres and, as mentioned previously, the higher number of components increases the risk of faults. The Multiplex systems offer better communication between the systems and simplify trouble-shooting.

The Multiplexer unit receives the information about the status of the switches. A coded value which is different for every switch, is transmitted to the Databus. The De-Multiplexer decodifies the values and activates the voltage to supply the appropriate lamp.

In Multiplexer systems various types of cables are used: the most cost-effective alternative is that of single cables. Further alternatives are: double or dual cable, twisted pair cables, optical fibres. The choice of the cable depends on the following requirements: signal speed, signal noise and interferences and this choice affects the overall cost of the system.

Print 603.93.121

CURSOR 8/10/13

Different classes exist depending on the different data transmission speed on the Databus: - class A: low speed (example: windscreen wiper and vehicle lights control).

- Class B: medium speed (example: air conditioning and sound systems).

- Class C: high speed (example: ABS and Traction Control systems).

All in all the advantages of a Multiplex system can be summarised in: lower costs due to the lower length of the cables, higher functionality, sharing of the signals of the sensors by the various systems and better diagnostic functions. Against this however, the overall number of connections increases, technical training requisites are higher, function reading is not possible through the wiring diagram and above all higher costs compared with a conventional system.

INTRODUCTION

I.13

Since all the components that take part in communication can send messages simultaneously on the bus, the receiving component concerned will firstly receive the message with the highest priority while the others will return to the sender and be transmitted again: for example concerning vehicle driving are of primary importance and therefore the vehicle must react immediately to changes of the pedal position; it is also true that if important messages are transmitted constantly, the less important information will rarely or never reach its destination.

For this reason different buses are used.

The different manufacturers use their own standards on their vehicles. In Germany BOSCH has developed the Bus CAN (Control Area Network).

All the nodes, i.e. electronic control units, are connected on the Databus.

The structure of the BusCAN is extremely flexible; one or more nodes may be added or removed easily and continue working in the event of a fault of one or more of them.

If node 2 sends a message, node 3 which is concerned accepts the message, while node 1 ignores it. It is important to know that the messages have been received correctly on the Databus; in the case of an error the message is sent again: the receiving node confirms reception of the message.

BUS MULTIPLEX (CAN)

The units or nodes can share the information of many sensors.

As for any form of communication certain conditions must be met. CAN communication needs the right hardware, a task that was initially performed by a single microchip but which lately has been increasingly integrated in microcontrollers: the Can-Chip developed by Bosch makes the various control units communicate with one another with CAN protocol through the same ”language” via bus; as transmitter it confers the messages to everyone and as receiver it is capable of identifying the messages addressed to it among many messages.

CURSOR ENGINE DESCRIPTION Configuration of engines belonging to family 2 and family 3 (Cursor) The engines to be installed on medium-heavy and heavy vehicles, to replace traditional engines gradually, belong to “families” 2 and 3.

The cylinder displacements are different since they cover different power ranges.

The injection system of these engines is of high pressure type with pump - injector actuated by the head camshaft, with different dimensions and capacity between F2 and F3, but similar operation.

The electronic control unit is physically the same on all versions, but it contains a specific software for each engine family and, inside each family, for different power calibrations. During service operations it is not possible to work on each control unit software, save for entering certain configuration data, if required (e.g., to replace pump - injectors), through Modus.

POWER NETWORK Never disconnect the batteries from the system with the engine running.

When needing to disconnect the batteries from the system, always firstly disconnect the frame earth cable from the negative terminal of the batteries.

Before connecting the batteries to the system, make sure that the system is well insulated.

Disconnect the batteries from the system when charging them.

M1

The purpose of the electric system is to generate, regulate, store and distribute the energy needed to make the vehicle components work.

For this reason the supply of the base electric system is ensured by a generator (28V - 60A -90A alternator) and two batteries, each with 12 V 110 Ah (143 Ah - 170 Ah) connected in series.

EARTH POINT OF BATTERIES ON LEFT SIDEMEMBER

Negative network The batteries are connected to the frame earth with a brown 70 mm2 cable, at earth point M1 on the left sidemember (Fig. II.8).

The starter motor is connected to the frame earth (M2/1) through a 70 mm2 cable, fastened on the right sidemember (Fig. II.9), near the actual motor. The same cable serves for connecting the whole engine unit to the frame earth.

M2/1

The vehicle cab is given the same negative electrical equipotential as the frame through a braid (Fig. II.10) connected to the cab front and on the right front sidemember.

CURSOR 8/10/13

Earth points on the vehicle (EuroTech - EuroStar) The main causes of voltage drop in the electric system of a vehicle are chiefly due to two factors: 1. the negative network; 2. earth points To minimise the above factors the following have been introduced on the vehicle: a. the length of the cab/frame negative lead has been reduced and an appropriate cross-section has been defined according to the load; b. the already existing earth points M1 and M2 have been confirmed; c. earth points M3-M4-M5 have been subdivided to create individual earth, signal and power nodes; d. an earth point (M11) has been provided on the frame (right side) for the tail lights; e. an earth point has been inserted on the engine (M10); With equipment increasingly more consisting of analogue/digital components on vehicles, the above factors (Points 1 and 2) are tending to become more important.

Though generally protected by the effect of the current of the services on board, electronic components still remain particularly sensitive to problems of electromagnetic compatibility.

These problems may be of different nature.

1. generated by the vehicle; 2. of an outside source.

To minimise these phenomena a flexible electrolytic copper braid of appropriate size has been adopted on vehicles in order to re-conduct the main structures of the vehicle (cab - frame) to the equipotential state.

For this purpose, earth point ”T1” has been introduced between the frame and cab.

Starting During starting from the driver’s seat, the safety devices (handbrake, gearbox in neutral) normally present, with the cab tilted, when starting from the engine compartment, are cut off.

Before working on the vehicle, chock the wheels to prevent the vehicle from moving accidentally. Before tilting the cab, make sure that the space in front of the vehicle is sufficient. Starting from the engine compartment may only be carried out when the cab is firmly fastened on its maximum opening position, with the handbrake engaged and the gearbox in neutral.

A

As shown in fig. II.24, the two starting systems (from engine compartment with cab tilted and from the driver’s seat with the cab coupled) cut one another out.

Starting from the driver’s seat (Cab coupled) Starting from the driver’s seat (synoptic of Fig. II.24 ref.

A) is done by taking the ignition switch 52502 to position 50; this way, through the normally closed contact between terminal 30 and 87b of the enable relay for starting outside the vehicle 25204, the engagement is controlled of the relay for starting 25200 (terminal 86), which, by closing the contact between terminals 30 and 87, takes the supply (+30) to terminal 30 of relay 25224 which in turn supplies terminal 50 of the starter motor 08000 from terminal 87.

NB To make the working contacts 30 and 87 of relay 25224 close, relay 25874 must receive a negative signal from terminal L of the alternator at terminal 85, and a positive signal from fuse 13 of the UCI under 15 at positive terminal 86. At this point, closing the work contacts of the relay, terminal 85 of relay 25224 is supplied with a negative signal from terminal 30 and as terminal 86 is already supplied by fuse 13 (+15), the work contacts 30 and 87 close, thereby supplying terminal 50 of the starter motor.

Speed regulator (Cruise Control) (Function active starting from 20 km / h up to the vehicle maximum speed) This system automatically maintains the vehicle travelling speed without using the accelerator pedal.

Should the vehicle speed raise by 2 km / h compared to the set speed (e.g. because driving on a slope) the engine brake is automatically activated to slow down the vehicle.

The Cruise Control must not be used in the traffic jam and on roads where it is difficult to keep the speed constant (e.g. on hills).

This function shall be activated only in the following conditions: Engine brake control off “when releasing the accelerator”.

Vehicle moving with gear engaged.

Vehicle speed higher than 20 km / h.

Brake pedal not depressed.

Clutch pedal not depressed.

Engine brake disengaged.

Should the brake, the engine brake or the clutch pedal be depressed, the Cruise Control is disengaged. The same happens if the set minimum speed is not reached. The speed maximum limit is stored by the programme inside the control electronic module and cannot be adjusted.

Cruise — Control disengagement The system can be disengaged: Manually and in a permanent way (by pressing the button to OFF).

Automatically and in a permanent way by pressing the brake, the engine brake and the clutch pedal. With automatic transmission, it is disengaged during gearshifting Automatically and in a permanent way by pressing the accelerator pedal (thus requesting a speed higher than the set one) for more than 30 seconds.

After disengagement, it is possible to restore the previously set vehicle cruise speed by pressing the switch to RES. The system is temporarily deactivated when a speed higher than the set one is requested with the accelerator pedal (for no more than 30 seconds). As soon as the accelerator pedal is released, the function is automatically restored with the last stored value.

A. The SET + switch has the following functions: - pressed only once, it activates the function and maintains the speed set by the accelerator pedal in that moment. From now on it is possible to release the accelerator pedal and the vehicle will maintain the set cruise speed: - when the speed has already been set, it is used to raise the vehicle speed without pressing the accelerator pedal.

B. The SET — switch has the following function: - when the speed has already been set, it is used to reduce the vehicle speed without engaging the service brake.

C. When the switch is pressed on the right (RES) it has the following function: - it activates the function and automatically adjusts the vehicle speed to the last value stored after starting the engine (last set value before disengagement), on the basis of the selected gear.

D. When the switch is pressed on the left (OFF), it deactivates the function.
