INTRODUCTIONFault Codes and Fault Finding

The tractors have an inbuilt self diagnostic facility.This facility utilises the digital display of theInstrument cluster and Gear display to indicate, incoded format, malfunctions in the electrical andelectronic circuitry and in the micro--processor. Itshould be noted that the self diagnostic capability isgenerally limited to diagnosis of the electrical andelectronic circuitry and related components,however, there are some codes, which can begenerated if pressure switch circuits are not closedbecause of an actual lack of hydraulic pressure. Anymalfunction of the mechanical and hydrauliccomponents must be diagnosed using conventionaltechniques, performance characteristics and tooling,such as pressure testing equipment.

Trouble--shooting and fault finding should always becarried out in a logical and planned sequence, manyapparent faults associated with electroniccomponents are oftenhastily diagnosedand result inthe replacement of expensive components. Anextrafew minutes confirming the apparent fault will resultin a more positive and cost effective repair.

With the use of micro--processors it is often that thisitem is blamed for any malfunction but the real truthis that this item is usually sound and that the fault isdue to poor contacts in the associated connectors.

Each electrical connector illustrated and identified inthe wiring diagrams in Section 55 and referred to inthe following fault finding procedures, has the sameidentification reference. For example, one of theprocessor connectors is referred to as ConnectorC537 in the illustration and also referred to as C537in the fault finding procedure. In the fault findingprocedure the connector, pin and wire colour areshownas, C537pin 25 (U/R/B). If all thewires are thesamecolour, the circuit number is also included toaidin wire identification. For example, C537 pin 25(7000T--U/R/B). This is broken down as follows:

C537 Connector number7000T Circuit numberU/R/B Wire colour

All tests are carried out on the harness side of theconnector, unless otherwise stated.

Refer to Section 55 Chapter 14C for complete wiringdiagrams and how to use them.

Where the fault finding procedure requires checksfor continuity a visual inspection of the wiring shouldbe made prior to conducting tests to ensure thatobvious ‘mechanical’ damage has not occurred tothe harness or the connectors.

A good quality multi--meter is an essential item toperform fault finding. It should be capable ofmeasuring resistance of at least 20,000 ohms andmeasuring voltage and current. When using themulti--meter it is good practice to select a high rangeand work downwards to avoid damaging theinstrument. Refer to the ’Basic Multi--Meter use’section of this chapter for further details.

IMPORTANT: Care should be used when using themulti--meter, only use the instrument as instructed toavoid damage to the internal elements of themicro--processor. When checking the continuity ofwiring, sensors or switches it is necessary to isolatethe electronic micro--processor and ensure thekeystart is turned off to prevent possible furtherdamage. The keystart should only be switched onand the processor connected where specificallyinstructed in the fault finding procedure.

If it is found necessary to clean the connectors acontact spray should be used. DO NOT USE ANYOTHER METHOD FOR CLEANING TERMINALS.Do not use a cleaner that containsTrichloro--ethylene, this solvent will damage theplastic body of the connector. It is preferable to usea cleaner with a Freon T.F. base.

WIRING HARNESS REPAIRS

Temporary Wiring Harness Repair

WARNINGIt is acceptable to use the following repair procedureon the CAN BUS wiring. It is important though toensure that the wire lengths are not altered from theoriginal as this will affect the performance of theCANBUS system.

The following method to repair wiring is a temporaryexpedient only. Wiring should be replaced as soonas possible. Do not attempt to repair the wire on anysystem sensors as these are sealed and should onlybe replaced with a new component.NOTE: When conducting a cable repair it isimportant that only RESIN CORED SOLDER isused. Use of other types of solder may result infurther cable damage.To carry out a temporary repair, proceed as follows:--1. Locate damaged portion of cable then cut away

outer protective cover on both sides of thedamaged area, Figure 1.

12. Using a suitable solvent, clean about 2 inches

(50 mm) from each cover end. Clean the greycable cover and the individual leads.



604.55.111.02 -- 02 -- 2006

3. Twist two bare leads together for each damagedlead, being careful to match wire colours, thensolder the leads using resin cored solder. Tapeeach repaired lead with vinyl insulation tape,Figure 2.

24. Winda layer of vinyl insulation tape up to thegrey

cable cover at each end of the repair section.Make a paper trough, Figure 3, then applysilicon rubber compound (non hardeningsealant) over the repaired section up to the coverends. Sufficient sealant must be used to fill theends of the cut away area.

35. Allow the compound to cure then cover the area

with insulating tape taking the tape well overeach end of the repair. An overlap of at least 2inches (50mm) of tape at each end is necessary,Figure 4.

6. Check to ensure the repair is satisfactory andsecure the repaired cable so that repeat damageis avoided.

NOTE: This is a temporary repair only. Ensure thedamaged cable is replaced as soon as possible toprevent ingress of water or chemicals.

Harness Wire Replacement

If a wire within the harness is found to be beyondrepair or is open circuit, a jumper wire may beinstalled as a temporary repair until such timewhenanew harness assembly can be installed. Use thefollowing procedure to install an additional wire:

1. Locate the faulty wire using the proceduresdescribed in the fault code charts.

2. Disconnect the affected connectors.3. If fitted carefully roll back the seal between the

connector and harness outer covering.4. Remove the pins from the connector blocks of

the affected wire using the appropriate removaltool found in the harness repair kit.

NOTE: Use the instructions supplied with the kit toensure correct pin removal.

55. From the harness repair kit select the correct pin

for the connectors. Obtain locally the correctcross--sectional size wire and measure out thelength required by following the harness routing.

6. Join the new wire to the new pins as describedin theharness repair kit and install oneof thepinsinto its connector.

7. If possible attempt to run the new wire within theexisting harness outer covering, if this is notpossible run thewire along the harness, securingregularly with suitable ties. With the wirecorrectly routed instal the second terminal into itsconnector block. Replace the connector seal ifremoved.

8. To ensure that the repair has been effectivecheck for continuity of the new wire using asuitable multi--meter.

NOTE: This is a temporary repair only. Ensure thedamaged cable is replaced as soon as possible toprevent ingress of water or chemicals.

THE DIGITAL MULTI--METERNOTE: This section is only intended as a generalguide to using a digital multimeter.Always refer to the manufactures operators manualfor correct operation

A multimeter is an electronic measuring device. Thedifferent types of measurement that can be madedepend upon the make and model of the multimeter.Most types of multimeter have the capacity tomeasure:

• Current (A) ac or dc

• Resistance (Ω)

• Voltage (V) ac or dc

• Continuity (Buzz test)

More expensive multimeters have other functions,such as the capacity to measure frequency (Hz) andtest diodes. 7

General Operation:

Before proceeding with a test, decide on what isgoing to bemeasured (Voltage, Current etc.). Rotatethe dial until the pointer is within the relevant zone.Within each zone there are different scales. Thescale that is selected will represent the maximumvalue that the multimeter will read. Always select ascale which is greater than the value that you intendto measure. If you are unsure of the value to bemeasured, always select the highest scale and thenreduce the scale once you have an idea of themeasured value.

8Why are there different scales ?

The closer that the scale is to the measured value,the more accurate the reading will bee.g. If measuring the voltage of a battery with thescale set at 200V, the display may read 12V.However, if the scale was set to 20V the display mayread a more accurate reading of 12.27V

9



604.55.111.02 -- 02 -- 2006

Measuring Voltage (Volts):

Set the rangedial to either ac or dc volts. Connect theBlack test probe to the ”COM” terminal and the Redtest probe to the ”V/Ω” terminal. Place the test probesacross the component to be measured with thecircuit complete (closed). Read off the display value

10Measuring Current (Amps):

Set the range dial to either ac or dc current. Whenmeasuring current up to 2 amps, connect the Redtest probe to the “A” terminal. When measuringcurrent up to 10 amps, connect the Red test probe tothe 10 “A” terminal. Always connect the Black testprobe to the “COM” terminal. When takingmeasurement of current, always break the circuitand connect the multi meter in series with the circuit.Read off the display value.

NOTE:For protection,multimeters are usually fusedat 1OA.

11Measuring Resistance (Ohms):

Set the range dial to the desired Q position. ConnecttheRed test probe to the “V/Ω” terminal. Connect theBlack test probe to the “COM” terminal. If theresistance being measured is connected in a circuit,then turn off the power to the circuit. Connect the testprobes to the measuring point and read off thedisplay value.

12



604.55.111.02 -- 02 -- 2006

Continuity (Buzzer) test:

Set the range dial to the “Buzz” position. Connect theRed test probe to the “V/Ω” terminal. Connect theBlack test probe to the “COM” terminal. Connect thetest probes to the measuring point. In general, if theresistance is less than 50Ω then the buzzer willsound, indicating continuity.

13Note: Buzzers on different multi meters will sound atdifferent ohmic values, depending on the quality ofthe meter. This can often be misleading. Forexample, when checking a corroded earth point. Apoor qualitymulti metermay buzz at 150Ω, indicatingcontinuity and no problem. When using a higherquality multi meter for the same test, it would notbuzz due to the high resistance. When carrying outsuch tests, we should always check the value ofresistance as well as listening out for the buzz.

A good connection gives low resistance.

A bad connection gives high resistance.

14SUMMARY:

When measuring --

Voltage (V):Connect across the component with the circuitclosed.

Current (A):Connect in series with the circuit. Circuit closed.

Resistance (Ω):Connect across the component with the circuit open.

Continuity (Buzz):Connect the meter across the component with thecircuit open. (Always check the value of resistanceas well!!)

ELECTRICAL TEST PROCEDURES

Four electrical tests will be required to properlytroubleshoot electrical concerns on the vehicle.

Each test is described in detail. Ensure that all stepsare reviewed and followed when testing.

1. Continuity Test, Short to ground2. Voltage measurement, short to 12 volts3. Resistance test for components4. Continuity test, Open circuits

ELECTRICAL TEST PROCEDURE 1:CONTINUITY TEST - SHORT TO GROUND

CONDITIONS FOR PERFORMING TESTS:1. Power OFF, KeyswitchOFF, (sometimes battery

disconnected or fuse pulled out if specified inprocedure).

2. Connectors at each end or ends of circuitdisconnected to prevent false readings.

3. Set meter to measure resistance or ohms, andmeasure circuit resistance. Use black lead tomake contact with a plated metal part on thechassis such as a jump start post if fitted. Makesure the surface of the part is not corroded. Usethe red meter lead to touch the connector pins,one pin at a time, and avoid contact with the caseof metal connectors.

4. Determine if measured resistance falls withinguidelines specified in the procedure. 3 to 4ohms indicates a direct short to chassis groundand must be located and repaired. Higherresistances usually indicate circuit paths throughmodules, and that an additional connector needsto bedisconnected to perform the test.More than100K ohms indicates that the circuit is free ofshorts to ground.

ELECTRICAL TEST PROCEDURE 2: VOLTAGEMEASUREMENT OR SHORT TO POSITIVESUPPLY VOLTS

CONDITIONS FOR PERFORMING SHORT TOPOSITIVE SUPPLY TESTS:1. Keyswitch ON (sometimes OFF, if specified in

procedure).2. Connectors at sensor, switch or potentiometer

end disconnected. All other connectors must bereconnected to perform test.

3. Set meter to measure DC VOLTS, andmeasurecircuit voltage as illustrated. Use the red meterlead to touch the connector pins, one pin at atime, and avoid contact with the case of metalconnectors. Use the black lead to make contactwith a plated metal part on the chassis such asa jump start post if fitted. Make sure the surfaceof the part is not corroded.

4. Determine if measured voltage falls withinguidelines specified in the procedure.

16ELECTRICAL TEST PROCEDURE 3:RESISTANCE TEST FOR ELECTRICAL PARTS

CONDITIONS FOR PERFORMING RESISTANCETEST1. Disconnect tractor part by unplugging electrical

CIRCUIT COMPONENTS -- BASICDESCRIPTION

CIRCUIT PROTECTION DEVICES

Circuit protection devices are used to protect wiringand components from excessive current. Threedifferent types of protection are fitted in tractors. Twoof them (fuses and fusible links) are currently used,while circuit breakers are no longer used.

19FUSES, FUSIBLE LINKS

Fuses and fusible links protect circuits with thinpieces of metal and wire which heat up and melt toopen up the circuit when too much current flowsthrough them.

Fuses are used to protect the circuit from overload.This can occur in the event of a short circuit or byconnecting equipment which demands a currentgreater than the circuit is designed to carry.

There are several types of fuses, but they all consistof a metal conductor which is capable of carrying alimited current. If the specified current is exceededthen the metal conductor will overheat, causing it tomelt andbreak. Thiswill in turn causean opencircuit.

The rating of the fuse relates to the current that thefuse can carry continuously.

If a fuse blows, it must be replaced with a fuse of thecorrect rating, and if it blows again, then the causemust be investigated.

20

FUSE LINKS

A fuse link is a wire that acts like a fuse, breakingdown and causing an open circuit when the currentthat passes through it exceeds a certain amperage.For primary fuse protection the main supplies fromthe starter solenoid are fitted with fuse links.

21



604.55.111.02 -- 02 -- 2006

CIRCUIT CONTROL DEVICES

Some of the components in a circuit are used tointerrupt and direct current flow either through anaction of the operator or automatically. The currentinterrupters you are probably most familiar with areswitches.

22SWITCHES

Switches are a vital part of an electric circuit,providing a method of controlling the circuit itself.One switch can control a number of different circuitsat the same time. This is achieved by having severalseparate connections and/or multi--connectorswitches (several switch ’positions’).

There are several types of switch, and they mayincorporate a warning light.

Switches can be as simple as that used to turn on animplement lamp or as complex as the ones used tooperate the starting and lighting systems. Checkingthe operation of switches is usually just a matter oftesting for power going into the switch and for powerleaving the switch at the appropriate contacts whenthe switch is operated.

One of the most common type of switches is thepressure switch (Fig. 23), a switch opened or closedby a fluid pressure. An example of this type of switchis the engine oil pressure switch, a simple on/offdevice that opens (or closes) when oil pressure risesabove 10 psi.

23



604.55.111.02 -- 02 -- 2006

FLASHERS

Flashers work automatically to interrupt and connectthe flow of current. Their operation is similar to that ofthe circuit breaker described earlier.

In the flasher, a heating element warms a bimetallicstrip. The strip bends, breaking contact with thepower source.When it cools, thebimetallic strip onceagain makes contact and the process begins again.

24DIODES

Some components use a semiconductor materialinstead of moving parts to direct current. Diodes forexample, allow current flow in one direction only.

They are essential in converting the alternatingcurrent that an alternator produces to the directcurrent that the tractor electrical systemcomponentsuse.

25RESISTANCE DEVICES

A number of electrical components alter or makeuseof electricity through their resistance to current flow.Resistors are components which are generally usedto regulate the supply of voltage and current to otherelectrical components.

In some cases, the purpose of resistance in anelectrical circuit is to provide light or heat. Lampsandcigar lighters are examples. Lamps convertelectricity into light, and cigar lighters convert it intoheat. Both lamps and lighters make use of the samephysical principle, that is Ohms Law.

26POTENTIOMETERS

Potentiometers are variable resistors which aredependant on mechanical movement, i.e. Lateralfloat movement, to vary the resistance of thecomponent and therefore alter the output voltage.

In order to verify the correct operation of apotentiometer, the resistance should bemeasuredatthe minimum and maximum positions and a smoothand continuous change of resistance should beobserved between. As the resistance varies withtemperature, the test specifications are usually givenat 20 °C.

27



604.55.111.02 -- 02 -- 2006

ELECTROMAGNETIC DEVICES

In general, they use the magnetic field created byflowing current to move metal parts within thecomponents.

RELAYS

The relay is an electromagnetic switch that uses asmall amount of current to switch a larger amount onand off.

When the operator closes a switch, current flowsthrough the relay’s control circuit. In this circuit thereare windings surrounding an iron core which is fixedin place (see Fig. 28).

Current turns the iron core into an electromagnet.The core then attracts an arm which has a contactpoint on it. When the point on the arm contacts thestationary point, current flows through the powercircuit.

Relays are basically electrically operated switches.They are used to switch a circuit on/off in similar wayto a manual switch.

Two circuits are connected to the relay:

• A work circuit, which is switched on/off bythe relay, and provides the supply for theequipment to be operated, i.e., bulbs,solenoids, etc.;

• A control circuit, switched on/off by manualswitches, used to operate the relay.

Thepart of the relaywhich is connected to the controlcircuit consists of the winding of an electro--magnet.When the control circuit is switched off, the contactsare kept apart by a return spring. When the controlcircuit is switched on, a current flows through the coiland a magnetic force is produced. This force, whichis stronger than the spring pressure, pulls thecontacts of the relay together, causing the workcircuit to operate.

28



604.55.111.02 -- 02 -- 2006

A switch--relay system has two main advantagesover a simple switch:

• The current that flows through the switch isnot the same as all the current requested bythe equipment to be operated, but usuallybya smaller current: this allows the usageofsmaller and less expensive switches;

• The distance from the supply, to theequipment, can be made as short aspossible to minimise voltage drop.

There are several types of relays. They can benormally open or normally closed. They may haveinternal electronic circuits to give special operatingfeatures. For example, they can turn the switchon/off at timed intervals (flasher relay), be sensitiveto current, temperature, etc. The relay cover usuallygives information about the features of the relay.

On the relay cover there are usually 4 or 5 terminalmarkings :

• 30: input terminal direct from batterypositive, normally live.

• 85: winding output terminal, usually toground.

• 86: winding input terminal.

• 87: output terminal for normally closedcontact.

• 87a: output terminal for normally opencontact.

Brown relays are normally open relays, blueones arenormally closed.

29

SOLENOIDS

Solenoids (Fig. 30) work in much the same way asrelays, except that the iron core is not fixed in place.As a result, the windings in the control circuit causethe iron core to move.

In the starting system, for example, themovement ofthis core is used to send large amounts of current tothe starter motor.

A solenoid is basically a winding around an iron core.In the centre of the core there is a plunger which isfree to move through the core. When an electricalcurrent passes through the winding anelectro--magnetic force is produced which causesthe plunger tomove through the core. If the current isswitched off, the magnetic force is stopped and theplunger is returned by a spring.

30



604.55.111.02 -- 02 -- 2006

The solenoid plunger may have different uses: themost common are moving a hydraulic spool or amechanical lever.

The use of solenoids to control hydraulic pressureinstead of the hydraulic valves is highlyrecommended wherever there is a long distancebetween the control panel and the valve (more than10 meters) or a fast action is required.

A coil should:

• Be non--sensitive to vibrations;

• Be silent in operation

• Have large frequency of activation (30--35 timesper second)

• It should be possible to fit it in any position.

• Be insulated, in order to function correctly for awide range of temperatures (--40 to +85°C), andwith high humidity conditions.

The MOST COMMON FAULTS that can occur are:

• Short circuit winding: if a section of the windingallows the current to pass directly from positive(+) to negative (--) terminals without passingthrough the winding, this will cause the relevantcircuit fuse to blow.

• Broken winding: causing an open circuit, it willnot allow the current to pass through thewinding,so the solenoid will not operate.

• Seizedplunger (and/or connected components):the solenoid will only move the plunger if allcomponents are free to move.

PWM SOLENOID VALVES

Whenever it is necessary to provide proportionalcontrol to the solenoid valves, it is much better to usea principle of operation called pulsewidthmodulation(PWM). PWM is a variable DC voltage signal that isused to control the solenoid valves. The voltagesignal is pulsed on and off many times a second (at aconstant frequency of 500 Hz) at a constant supplyvoltage of 12 V.

31



604.55.111.02 -- 02 -- 2006

The processors contain transistors that are suppliedwith a constant input voltage which is switched onand off to achieve the variable input range. In thisway the control module is able to limit the armaturemovement, so the hydraulic output flow of thesolenoid is proportional to the average DC voltage.The lower voltage alsoallows the solenoid to operatewith less residual magnetism and so the entire circuitwill operate smoother.

The variableDC voltage signal level is determinedbyvarying the duration of the ON pulse relative to theOFF pulse (see Fig. 32). The ratio between the ONtime and the cycle time is called duty cycle and isstated as a percentage of one complete cycle.

With reference to Fig. 32, diagrams 1 to 3 show thenormal operating range of the PWM valve, anddiagram 4 shows the initial 12V programming and filltime only. The diagrams in column A show thevoltage signal that is sent to the valve, whereascolumn B shows the relevant spring pressure andcolumn C the reading on a voltmeter connected tothe solenoid valve.

Diagram 1 shows the OFF position: no signal isdirected to the valve, which means no springpressure in the valve at all and results in a zerovoltage reading. Increasing the duty cycle causessomepressure to bemadeon the circuit (Diagram2),which results in a voltmeter reading increase.Diagram 3 shows the maximum signal that is usedduring thenormal activity of the valve: its duty cycle isaround 0.5, which results in a spring pressure for thehalf of its run and in an indication of a 6 volt averageDC current.

The electrical circuit to the solenoids can be checkedby using a digital or analogue DC voltmeter, whichwill indicate the average voltage readings.

604.55.111.02 -- 02 -- 2006

SENSORS

A sensor is the primary component of ameasurement chain that converts the input variable(temperature, capacitance, reluctance) into a signalsuitable for measurement. The relationship betweenthe input variable and the measured signal is acharacteristic of the sensor.

In the above mentioned measurement chain thesignal is filtered and treated in order to adapt it to itsuse. It consists of three elements: the sensor itself;the converter, which converts the output signal fromthe sensor (in most of the cases into an electricsignal); and the conditioner, which transforms theoutput signal from the converter in the most suitableform. Generally the term sensor indicates the entiremeasurement chain.

TEMPERATURE SENSORS

Generally based on a simple circuit with a thermistor.A thermistor is a resistor that changes its resistanceaccording to the temperature.

There are two groups of thermistors: NTC (NegativeTemperature Coefficient) and PTC (positiveTemperature Coefficient). In the first case the higherthe temperature, the lower is the resistance, and forthe PTC the higher the temperature, the higher theresistance. The NTC are often used as sensors toindicate temperature change in fluids, such as theengine coolant fluid.

An example of these type of senders is the coolanttemperature sender. The changes in its resistance(which varies with temperature) are relayed to theInstrument Cluster, which operates the bargraphandthe warning indicators accordingly.

33

PRESSURE SENDER

A pressure sender receives a supply signal and itvaries it according to the (oil) pressure. An exampleis the oil pressure sender, which receives a 5 voltsignal and varies it according to the oil pressure. TheInstrument Cluster keeps track of these variationsand changes its readouts and warnings accordingly.

34



604.55.111.02 -- 02 -- 2006

SPEED SENSOR

Thespeedsensor is typically a reluctance sensor. Anexample is the axle speed sender, which is fitted intothe transmission and gets pulses off the gears,counting the gear teeth. The sender uses a pickupcoil close to four wheel drive coupling. The action ofthe gear close to the pickup creates pulses whicharerelayed to the Instrument Cluster. The InstrumentCluster converts the frequency of the pulses intoground speed.

Possible failures are due to vibration, open circuits.

35FLUID LEVEL SENDER

It operates by varying resistance through themovement of a float. An example is the fuel levelsender.

36



604.55.111.02 -- 02 -- 2006

ELECTRONIC MODULES (XCM, DIC, EMU)

The electronic modules are the ”black boxes” thatprovide control on many of the functions of thetractor. These functions may vary according to theoptions that are fitted on the tractor.

Inside these ”black boxes” there is a processor, the”thinking part” of the module, and inside some ofthem there is one or more memories, which mayallow the module to store calibration values, theconfiguration of the vehicle (which optional tools ordevices have been installed) and the error codes.

37A processor has a series of pins, which are electricalcontacts (seeFig. 38). There are threemain types ofpins: for the inputs of the signals, for the outputs andfor the processor supply.

The processor, the memories and the link betweenthem form the hardware of the module, its ”physical”part.

Then some software is needed, to handle thecommunication between the processor and thememories and to manage the various signals goinginto and out of the processor. The software isdesigned to operate in a different way for everymodule, and is called functional code. 38A serial data link is a kind of communication wheredata is sent along a single wire, so the informationregarding different functions of the same processorare sent to the Instrument Cluster in differentmoments.

To provide a continuous control on components, theprocessor continuously scans all the inputs in atime--sharing mode, with a cycle lasting 1Oms. Thismeans that all the components controlled by theprocessor are checked one by one, and that everycomponent is checked 100 times per second.

The electronic modules are often blamed asresponsible for most of the problems of the moderntractors, while they are for certain among the mostprotected parts of the tractor. In fact, the pins of themodule are protected against spikes (high pulses) ofcurrent, and the signals are filtered by the hardwareand by the software in input and in output to give thebest handling of information.

CONTROLLED AREA NETWORK (CAN)SYSTEMThe Semi Powershift model uses a conventionaltype of wiring harness to connect togethercomponents and processors.A CAN (Controlled Area Network) is used in additionto the standard wiring harnesses to connect thedisplay of gears module to the central controller(XCM). The CAN is a 2--wire system which uses aseries of numeric values sent at very high speed totransmit data between processors and components.A CAN system has the advantage of being able touse one component for many applications withoutthe need for hard wiring to each application, as in aconventional system.Processors are used to control transmissions,hydraulic lift, PTO systems, four wheel drive,differential lock, creeper engagement, enginecoolant fan and fuel injection pump.

FAULT DISPLAY LOGIC -- RANGECOMMAND TRANSMISSIONSRangeCommand errors are displayedon thedisplayof gears (DOG) and are prefixed with an F.Fault codes always flash.There are four types of errors: Disabling, N, CP, andHidden.Disabling errors disable the transmissionpermanently (until the next power-up).Disabling and hidden errors are accompanied by asteady alarm for 5 seconds. After 5 seconds, theerror code continues flashing on the LCD, but thealarm stops. If the error clears during the 5 secondperiod, the alarm will stop when the error clears, andthe LCD will return to normal display.If there are multiple disabling or hidden errors todisplay, they will be displayed sequentially. Example,for codes F2A, F2b and F2C:LCD: | F2A------ | F2b------ | F2C------ | F2A | F2C |F2A |Time: | 5 sec | 1 s | 5 sec | 1 s | 5 sec | 1s | 5 sec | 5sec | 5 sec | 5 sec | etc...Alarm: |steady |off|steady |off|steady |off|off--------------------------------------

40

NOTE: The display sequence may not always startwith the lowest error number, and the errors may notbe displayed in numerical order at first. There issome randomness depending on the exact timingand sequence of events.N and CP errors are accompanied by a pulse alarmand require action from the driver. The alarm willcontinue and the transmission is disabled until thedriver takes action.

CP can be cleared by cycling the clutch pedal. Insome cases, CP can also be cleared by cyclingthe shuttle lever.N can be cleared by shifting the shuttle lever toneutral.N and CP can result from improper action by thedriver, or they can result from faults in the systemwhich require action from the driver to re-startoperation.

41



604.55.111.02 -- 02 -- 2006

Normal error display mode:If there are any disabling errors, only disablingerrors will be displayed.If there are no disabling errors and at least oneN error is active, N will flash.If there are no disabling errors and no N errors,and at least one CP error is active, CP will flash.Hidden errors will not be displayed.

42Hd in the diagnostic menu will enable ‘display allerrors‘ mode. Also, a new module (or an old moduleafter the memory has been reset using H8) willautomatically be in ‘display all errors‘ mode untilthere are no errors to display for 6 minutes. The sixminutes must be during one power-on cycle, i.e.turning off the key switch zeros the timer.

43If there are any disabling errors. ALL errors will bedisplayed sequentially. N and CP will not bedisplayed; instead, the error codes associated withthe N or CP fault will be displayed.If there are no disabling errors and there is at leastone N error, the first N error will be displayed. Thedisplay will alternate at one second each between N(to tell the driver what to do) and the associated errorcode (to assist with trouble shooting).

44If there are no disabling errors or N errors, and thereis at least one CP error, the first CP error will bedisplayed. The display will alternate at one secondeach between CP (to tell the driver what to do) andthe associated error code (to assist with troubleshooting).If there are nodisabling errors, Nerrors, orCPerrors,any hidden errors will be displayed sequentially.

604.55.111.02 -- 02 -- 2006

A new module, or an old module after the memoryhas been reset using H8, will automatically be in”display all errors” mode until there are no errors todisplay for 6 minutes. The 6 minutes must be duringone power-on cycle, i.e. turning off the key switchzeros the timer. After six minutes with no errors, themodule switches automatically to normal errordisplay mode, and all stored error codes are erased.

Possible failure modes:1. Faulty connector2. Faulty harness3. Faulty vistronic fan4. Faulty central controller (XCM)

Solution:NOTE:When the cause of the error code has been rectified, clear the error code and test the system for normaloperation.1. Check the vistronic fan connector C275, the inline harness connector C001 and the central controller

connector (XCM) C537.A. Ensure the connectors are connected, not damaged, the pins are in the correct position and that the fitis tight. Repair or replace as required.B. If the connectors are okay, continue to step 2.

2. Check for +5 Volts.A. Disconnect connector C275. Turn the keysart ON. Measure the volatge between connector C275 pin 5(N/Y/S) and ground. If +5 volts is not indicated, repair or replace the hraness as required..B. If +5 volts is indicated, continue to step 3.

3. Check the vistronic fan.A. Turn the keystart OFF. Measure the resistance between the component side of connector C275 pin 4(N/W/S) andC275 pin 3. If the resistance indicated is not approximately 6.8 Ohms, remove and replace thevistronic fan.B. If the resistance indicated is approximately 6.8 Ohms, continue to step 4.

4. Check for a short to groundA. Check between connector:C275 pin 1 (N/U/S) and groundC275 pin 4 (N/W/S) and groundIf a short to ground is indicated, repair or replace the harness as required.B. If a short to ground is not indicated, continue to step 5.

5. Check for a short to +Ve voltage.A. Turn the keystart ON. Measure the voltage between connector:C275 pin 1 (N/U/S) and groundC275 pin 4 (N/W/S) and groundIf a volatge is indicated, repair or replace the harness as required.B. If a voltage is not indicated, continue to step 6.

6. Check for an open circuit.A. Turn the keystart OFF. Disconnect connector C537. Check between connector:C275 pin 1 (N/U/S) and C537 pin 19 (N/U/S)C275 pin 2 (B) and groundC275 pin 3 (B) and groundC275 pin 4 (N/W/S) and C537 pin 8 (N/U/S)If an open circuit is indicated, repair or replace the harness as required.B. If the harness is okay, remove and replace the vistronic fan. If the fault re--occurs, download the correctlevel of software. If the the fault is still present, remove and replace the central controller (XCM).
