KENR6224

Electronic Cont rols

The electronic system consists of the following

components: the ECM, the Mechanically Actuated

Electronically Controlled Unit Injectors (MEUI), the

wiring harness, the switches, and the sensors. The

ECM is the computer. The flash file is the software

for the computer. The flash file contains the operating

maps. The operating maps define the following

characteristics of the engine:

• Horsepower

• Torque curves

The ECM determines the timing and the amount of

fuel that is delivered to the cy linders. These decisions

are based on the ac tual conditions and/or on the

desired conditions at any given time.

The ECM compares the desired engine speed to

the actual engine speed. The actual engine speed is

determined through the engine speed/timing sensor.

The desired engine speed is determined with the

following factors:

• Throttle signal

• Other input signals from sensors

• Certain diagnostic codes

If the desired engine speed is greater than the actual

engine speed, the ECM injects more fuel in order to

increase the actual engine speed.

Fuel Injection

The ECM controls the amount of fuel that is injected

by varying the signals to the injectors. The injector will

pump fuel only if the injector solenoid is energized.

The ECM sends a high voltage signal to the solenoid.

This high voltage signal energizes the solenoid. By

controlling the timing and the duration of the high

voltage signal, the ECM can c ontrol injection timing

and the ECM can control the amount of fuel that is

injected.

The ECM limits engine power during cold mode

operation and the ECM modifies injection timing

during cold mode operation. Cold mode operation

provides the following benefits:

• Increased cold weather starting capability

• Reduced warm-up time

• Reduced white smoke

Cold mode is activated whenever the engine

temperature falls below a predetermined value. Cold

mode remains active until the engine temperature

rises above a predetermined value or until a time

limit is exceeded.

The flash file inside the ECM sets certain limits on

the amount of fuel that can be injected. The “FRC

Fuel Limit” is used to control the air/fuel ratio for

control of emissions. The “FRC Fuel Limit” is a limit

that is based on the turbocharger outlet pressure.

A higher turbocharger outlet pressure indicates that

there is more air in the cylinder. When the ECM

senses a higher turbocharger outlet pressure, the

ECM increases the “FRC Fuel Limit”. When the ECM

increases the “FRC Fuel Limit”, the ECM allows

more fuel into the cylinder. The “FRC Fuel Limit” is

programmed into the ECM at the factory. The “FRC

Fuel Limit” cannot be changed.

The “Rated Fuel Limit” is a limit that is based on the

power rating of the engine and on engine rpm. The

“Rated Fuel Limit” is similar to the rack stops and to

the torque spring on a mechanically governed engine.

The “Rated Fuel Limit” provides the power curves

and the torque curves for a specific engine family and

for a spec ific engine rating. The “Rated Fuel Limit” is

programmed into the ECM at the factory. The “Rated

Fuel Limit” cannot be changed.

Once the ECM determines the amount of fuel that

is required, the ECM must determine the timing of

the fuel injection. The ECM uses the signal from the

camshaft position sensor to c alculate the top center

pos ition of eac h cylinder . The ECM decides when

fuel injection should occur relative to the top center

pos ition and the ECM provides the signal to the

injector at the desired time. The ECM adjusts timing

for optimum engine performance, for optimum fuel

economy, and for optimum control of white smoke.

Programmable Parameters

Certain parameters that affect the engine operation

may be changed with the Perkins Electronic

Service Tool (EST). The parameters are stored

in the ECM, and some parameters are protected

from unauthorized changes by passwords. These

pas swords are c alled factory passwords.

Passwords

Several system configuration parameters and most

logged events are protected by factory passwords .

Factory passwords are available only to Perkins

dealers and distributors. Refer to Troubleshooting,

“Factory Passwords” for additional information.

The Electronic Control Module (ECM) contains no

moving parts. Replacement of the ECM can be

costly. Replacement can also be a time consuming

task. Follow the troubleshooting procedures in this

manual in order to ensure that replacing the ECM will

correct the fault. Verify that the suspect ECM is the

cause of the fault.

Note: Ensure that the ECM is receiving power and

that the ECM is properly wired to the negative battery

circuit before a replacement of the ECM is attempted.

Refer to Troubleshooting, “Electrical Power Supply

Circuit - Test”.

A test ECM can be used to determine if the ECM is

faulty. Install a test ECM in place of the suspect ECM.

Flash program the correct flash file into the test ECM.

Program the parameters for normal operation of the

engine. The parameters must match the parameters

in the suspect ECM. Refer to the following test steps

for details. If the test ECM resolves the fault, connect

the suspect ECM. Verify that the fault returns. If the

fault returns, replace the suspect ECM.

Note: When a new ECM is not available, you may

need to remove an ECM from an engine that is not

in service. The interlock code for the replacement

ECM mus t match the interlock code for the suspect

ECM. Be sure to record the parameters from the

replacement ECM on the “Parameters Worksheet”.

Use the “Copy Configuration/ECM Replacement”

feature that is found under the “Service” menu on

Every generated code is stored in the permanent

memory of the ECM. The codes are logged.

Logged codes may not indicate that a repair is

needed. The fault may have been temporary. The

fault may have been resolved since the logging of

the code. If the system is powered, it is possible

to generate an active diagnostic code whenever a

component is disconnected. When the component is

reconnected, the code is no longer active. Logged

codes may be useful to help troubleshoot intermittent

faults. Logged codes can also be used to review

the performance of the engine and of the electronic

system.

Event Code

An event code is generated by the detection of an

abnormal engine operating condition. For example,

an event code will be generated if the oil pressure is

too low. In this case, the event c ode indicates the

symptom of a fault.

Self-Diagnostics

i02548823

The Electronic Control Module (ECM) has the ability

to detect faults with the electronic sys tem and with

engine operation. When a fault is detected, a code is

generated. An alarm may also be generated. There

are two types of codes:

• Diagnostic

• Event

Diagnostic Code – When a fault with the electronic

system is detected, the ECM generates a diagnostic

code. This indicates the specific fault with the

circuitry.

Diagnostic codes can have two different states:

• Active

• Logged

Active Code

An active diagnostic code indicates that an active

fault has been detected. Activ e c odes require

immediate attention. Always service active codes

prior to servicing logged codes.

ratings within the ECM will vary with the type of

engine and the specification of the engine.

currently selected rating. The following list gives the

possible configurations:

• Standby power

• Limited time prime power

• Prime power

• Continuous or baseload power

For definitions of these ratings, refer to ISO8528.

This parameter is read only.

Note: Not all of the above rating configurations will

be available in the software files of every ECM.

E xternal Speed Selection Switch Enable

For dual s peed applications with an external

speed selection switch, this parameter enables the

functionality of the speed selection switch within

the s oftware. Changing this parameter requires a

customer password.

Engine Startup Acceleration Rate

This parameter enables the ac celeration rate of

the engine in RPM per second to be programmed.

The parameter can be programmed from idle speed

to rated speed. Control of this parameter enables

any overshoot in speed on start-up to be limited.

Changing this parameter requires a c ustomer

pas sword.

Droop/Isochronous Switch Enable

This parameter determines whether the external

droop/isochronous switch is enabled or disabled.

Changing this parameter requires a c ustomer

pas sword.

KENR6224

27

Troubleshooting Section

Droop/Isochronous Selection

The engine will normally be run in isochronous mode.

This means that the engine speed will not change,

regardless of the load. If the engine needs to operate

in parallel with another genset or the engine needs

to operate in parallel with the grid, it is nec essary to

operate the engine in droop mode in order to ensure

the stability of the system. This parameter enables

droop/isochronous running selection. Changing this

parameter requires a customer pass word.

Note: If an external droop/isochronous switch is

enabled, the position of this switch will override the

“Droop/Is ochronous” selection.

Engine Speed Droop

If droop operation is selected, this parameter

allows the setting of percentage droop. This is the

percentage of speed reduction with an increase in

load. This parameter has no effect when the engine

is running in isochronous mode. Changing this

parameter requires a customer pass word.

Digital Speed Cont rol Installed

This parameter determines whether input from the

raise/lower switch controls the speed of the engine.

If digital speed control is not installed, the speed of

the engine is controlled by inputs from the analog

throttle or the PWM throttle. This depends on the

input that is selected in the desired speed input

configuration. Changing this parameter requires a

customer password.

Digital S peed Control Minimum Speed

This setting determines the minimum speed range of

both the raise/lower control and the analog control.

For example, if this is set to 100 RPM and the

nominal engine speed is s elected to 1500 RPM, the

minimum speed setting is 1400 RPM. This parameter

does not affect the range of the PWM speed control

as this control has a fixed minimum limit and a fixed

maximum limit. Changing this parameter requires a

customer password.

Digital S peed Control Maximum Speed

This setting determines the maximum speed range of

both the raise/lower control and the analog control. If

this is set to 100 RPM and the nominal engine speed

is selected to 1500 RPM, the maximum speed setting

is 1600 RPM. This setting does not affect the range

of the PWM speed control as this c ontrol has a fixed

minimum limit and a fixed maximum limit. Changing

this parameter requires a customer password.

Digital Speed Control Ramp Rate

This setting determines the rate of change of engine

speed in RPM when the raise/lower switch inputs are

closed. Changing this parameter requires a customer

pas sword.

Crank Terminate Speed

This parameter is used to set the engine speed that

is required before the output from the crank terminate

relay is switched. Changing this parameter requires a

customer password.

Desired Speed Input Arrangement

If a digital speed control is not installed, this

parameter enables selection of either an analog

throttle, a PWM throttle or an ex ternal CAN Bus

speed control. The inputs from the analog throttle,

the PWM throttle or the CAN Bus speed control

are normally used with genset load sharing and

synchronizing controllers. Changing this parameter

requires a customer password.

Note: If a PWM throttle, an analog throttle or a CAN

Bus speed control is selected but there are no inputs

to the terminals for the selected speed control, the

engine will default to running at 1100 RPM.

If a PWM throttle, an analog throttle or a CAN Bus

speed control is not used, the digital s peed control

should be selected.

Fuel Enable Input Configuration

This parameter enables the selection of switch to

battery positive or CAN input for the control of the

injector On and injector Off.

Governor Gain Parameters

The following items are the adjustable parameters for

gov ernor gain:

• Governor Gain Factor

• Governor Minimum Stability Factor

• Governor Maximum Stability

Note: No engineering units are associated with these

numbers.

Note: The programmable range is wide for flexibility.

Values of 1 to 40000 are valid. The full range of this

Determine the desired scenario in order to tune

the engine. For example, check if the engine has

poor response during specific load assignments

or specific load dumps.

Perform the desired load change that is detailed

in step 4. Check the response of the engine by

viewing the following parameters.

• The engine speed on the control panel on the

genset

• The frequency response of the system bus to

the load change

• Listening to the response of the engine

nec essary to bring the error to zero. The additional

fuel will cause the engine speed to overshoot and

the engine to produce excessive combustion noise.

stability gain is set too low, excessive time is taken

in order to stabilize the engine s peed.

Tuning Procedure

1. Turn the keyswitch to the OFF/RESET position.

Before the tuning procedure is started, connect

the electronic serv ice tool and then check

that engine overspeed protection is enabled.

Engine overspeed is configured on the

“Service\Monitoring System” sc reen on the

electronic service tool.,

NOTICE

Performing engine governor tuning without engine

overspeed protection could result in serious engine

damage.  Ens ure  that this  parameter is  ON while

performing this proc edure.

Note: Usually, the gain factor of the governor should

be lower than the minimum stability fac tor of the

gov ernor in order to obtain optimum performance.

The maximum stability factor is typically a smaller

value than the minimum stability gain and the

gov ernor gain factor.

7. Repeat steps 5, 6 and 7 until a desired engine

response can be met. Use large adjustments

(10% of original gain) initially to generally tune the

engine in the proper manner. As the response

gets closer to the desired value, increase the

gains in smaller increments (1% of total gain).

Engine monitoring

Perkins provides an engine monitoring system that

is ins talled at the factory. The system monitors the

following parameters:

• Engine oil pressure

• Coolant temperature

Diagnostic codes that are stored in memory are

called Logged diagnostic codes. The fault may have

been temporary or the fault may hav e been repaired

since the fault was logged. For this reason, logged

codes do not necessarily mean that something needs

to be repaired. Logged diagnostic codes are meant

to be an indication of probable causes for intermittent

faults.

The monitoring system has three levels of operation.

The levels are described below.

Warning Operation

In the Warning condition, the ECM causes the

warning lamp to come ON. The warning lamp

indicates that a fault has been detected by the engine

monitoring system. No further action by the ECM or

the engine occurs.

Action Alert Operation

In the Action Alert condition, the ECM causes the

action alert lamp to come on. The Action Alert lamp

indicates that a fault has been detected by the engine

monitoring system. This condition is normally wired

in order to cause a shutdown and the shutdown is

controlled by the control panel on the mac hine.

Shutdown Operation

If the fault reaches the Shutdown c ondition, the ECM

causes the shutdown lamp to come on. Unless the

engine is in a Critical Override condition, the engine

will shut down.

Monitoring the Fuel Temperature

The fuel temperature sensor monitors the fuel

temperature. The signal from the sensor allows

the ECM to compensate for changes in the fuel

temperature by adjusting the fuel rate for constant

power.

The sensor is also used to warn the operator of

exces sive fuel temperature with a diagnostic event

code. Excessive fuel temperatures can adversely

affect engine performance.

Self-Diagnostics

The electronic system has the ability to diagnose

faults. When a fault is detected, a diagnostic code

is generated and the diagnostic code is stored

in permanent memory (logged) in the ECM. The

diagnostic lamp is also activated.

When diagnostic codes occur, the diagnostic codes

are referred to as Active diagnostic codes. Active

diagnostic c odes indicate that a fault of some kind

currently exists.

Diagnostic codes that identify operating conditions

outside the normal operating range are called Events.

Event codes are not typically an indication of a fault

with the electronic system.

Note: Some of the diagnostic codes require

pas swords to clear the code.

Effect of Diagnostic Codes on

Engine Performance

The diagnostic lamp comes on when a specific

condition exists. When the ECM detects an engine

fault, the ECM generates an active diagnostic code

and the diagnostic code is logged. The diagnostic

code is logged in order to record the following

information:

• The date

• The time

• The number of occurrences of the fault

The two types of diagnostic codes are Fault codes

and Event codes.

Fault Codes

Fault codes are provided in order to indicate that

an electrical fault or an electronic fault has been

detected by the ECM. In some cases, the engine

performance can be affected by the condition that is

causing the code. More frequently, there is no effect

on engine performance.

Event Codes

Event codes are used to indicate that some

operational fault has been detected in the engine by

the ECM. This does not usually indicate an electronic

malfunction.

The ECM also provides a cloc k in order to add the

date and the time to the following critical event codes:

• 360-3 Low oil pressure shutdown

• 361-3 High coolant temperature shutdown

1. Crank the engine and observe the engine speed

on the status screen of the electronic service

tool. If the electronic service tool indicates zero

rpm, refer to the Troubleshooting Guide, “Engine

Position Sensor Circuit - Test”.

Note: Upon initial cranking, the status for engine

speed may indicate that the engine speed signal is

abnormal. This message will be replaced with an

engine s peed once the ECM is able to calculate a

speed from the signal.

2. If an engine s peed is present, check the sensor

ins tallation. If the sensor is not properly installed,

the ECM may read engine speed, but the ECM

cannot determine the tooth pattern. The ability for

the ECM to read the tooth pattern is necessary

to determine the cylinder position. Engine speed

is present when engine speed is greater than 50

rpm. Refer to the Troubleshooting Guide, “Engine

engine oil at the interval that is recommended by the

Operation and Maintenance Manual.

Contaminat ed Engine Oil

Drain the crankcase and refill the crankcase with

clean engine oil. Ins tall new engine oil filters. Refer to

the Operation and Maintenance Manual.

If the oil filter bypass valve is open, the oil will not

be filtered. Check the oil filter bypass valv e for a

weak spring or for a broken spring. If the spring is

broken, replace the spring. Refer to the Disassembly

and Assembly manual. Make sure that the oil bypass

valve is operating correctly.

Contaminated Air

Inspect the air inlet system for leaks. Inspect all of

the gaskets and the connections. Repair any leaks.

Inspect the air filter. Replace the air filter, if necessary.

Contaminated Fuel

Inspect the fuel filter. Replace the fuel filter, if

nec essary.

Contaminants in the fuel such as hy drogen sulfide

and sulfur can lead to the formation of acids in the

crankcase. Obtain a fuel analysis.

Low Oil Pressure

When some components of the engine show bearing

wear in a short time, the cause can be a restriction in

a passage for engine oil.

An indicator for the engine oil pressure may indicate

sufficient pressure, but a component is worn due to a

lack of lubrication. In s uch a case, look at the passage

for the engine oil supply to the component. Refer

the Troubleshooting Guide, “Diagnostic Code Cross

Reference” for a cross-reference between J1939

Diagnostic Code and diagnostic codes.

Do not confuse diagnostic codes with event codes.

Event codes alert the operator that an abnormal

operating condition such as low oil pressure or high

coolant temperature has been detected. Refer to

the Troubleshooting Guide, “Troubleshooting with

an Event Code” for additional information on event

codes.

Diagnostic Codes

Diagnostic codes alert the operator that a fault in

the elec tronic system has been detected. Diagnostic

codes also indicate the nature of the fault to the

service technician. The electronic service tool is

a software program that is designed to run on a

personal computer. Diagnostic codes may be viewed

on a personal computer that has the electronic

servic e tool s oftware. Diagnostic codes consist of

the component identifier (CID) and the failure mode

identifier (FMI).

Component Identifier (CID) – The CID is a number

with three or four digits. The CID indicates the

component that generated the code. For example,

the CID number 0001 identifies the fuel injector for

the number one cylinder.

Failure Mode Identifier (FMI) – The FMI is a two

digit code that indicates the type of failure.

Active Diagnostic Codes

Reference

Code

Cross

i02558820

An active diagnostic code represents a fault in the

electronic control system. Correct the fault as soon

as possible.

When the ECM generates an active diagnostic code,

the “Active Alarm” indicator (“Engine Control Alarm

Status” on the electronic service tool) is activated

in order to alert the operator. If the condition that

generated the code is momentary, the message

disappears from the list of active diagnostic codes.

The diagnostic code becomes logged.

Logged Diagnostic Codes

When the ECM generates a diagnostic code, the

ECM logs the code in permanent memory. The

ECM has an internal diagnostic clock. Each ECM

will record the following information when a code is

generated:

• The hour of the first occurrence of the code

• The hour of the last occurrence of the code

• The number of occurrences of the code

This information is a valuable indicator for

troubleshooting intermittent faults.

A code is cleared from memory when one of the

following conditions occur:

• The service technician manually clears the code.

• The code does not rec ur for 100 hours.

• A new code is logged and there are already ten

codes in memory. In this case, the oldest code is

cleared.

Some diagnostic codes may be easily triggered.

Some diagnostic codes may log occurrences that did

not result in complaints. The most likely cause of an

intermittent fault is a faulty c onnection or damaged

wiring. The nex t likely cause is a c omponent failure.

The least likely cause is the failure of an electronic

module. Diagnostic codes that are logged repeatedly

may indicate a fault that needs special investigation.

Note: Always clear logged diagnostic codes after

investigating and correcting the fault which generated

the code.

Faults in the electronic control system are reported

via thes e types of codes: flash codes, CID/FMI

diagnostic codes, and event codes.

For information on flash codes, refer to

Troubleshooting, “Flash Codes”.

For information on CID/FMI codes, refer to

Troubleshooting, “Diagnostic Codes”.

For information on event c odes, refer to

Event Codes

i02564763

Event codes alert the operator that an abnormal

engine operating condition such as low oil pressure or

high coolant temperature has been detected. When

the event code is generated, the event is active.

Active Event Codes

An active event code represents a fault with engine

operation. Correct the fault as soon as possible.

Active event codes are listed in ascending numerical

order. The code with the lowest number is listed first.

Illustration 11 is an example of the operating range of

a temperature sensor. Do not use the illustration to

troubleshoot temperature sensors.

Illustration 11

g01138880

Example of the typical operating range of a temperature sensor

(1) This area represents the normal operating range of the

parameter. The normal output voltage of the sensor is between

0.2 VDC and 4.2 VDC.

(2) In this area, the temperature above 107 °C (225 °F) is higher

than normal. The output voltage of the sensor will generate an

event code. The sensor does not have an electronic fault.

(3) In these areas, the output voltage of the sensor is too high

or too low. The voltage is outside of the normal range. The

elec tronic fault will generate a diagnostic code. Refer to

Troubleshooting, “Troubleshooting with a Diagnostic Code” for

additional information on diagnostic codes.

Events are represented in two formats. In the first

format, the “E” means that the code is an event

code. The “XXX” represents a numeric identifier for

the event code. This is followed by a description of

the code. If a warning, a derate, or a shutdown is

applicable, the numeric identifiers are different. Refer

to the following example:

• E004 Engine Overs peed Shutdown

In the second format, the “E” means that the

code is an event code. The “XXX-X” represents a

numeric identifier for the event code. The fourth “X”

identifies the event as a warning, an ac tion alert, or

a shutdown. This is followed by a description of the

code. Refer to the following example:

Troubleshooting

For basic troubleshooting of the engine, perform the

following steps in order to diagnose a fault:

1. Obtain the following information about the fault:

The definition for a warning, an action alert and a

shutdown are defined below:

Warning – This condition represents a serious fault

with engine operation. However, this c ondition does

not require an action alert or a s hutdown.

Action Alert – For this condition, the OEM control

panel may shut down the engine.

Shutdown – For this condition, the ECM should shut

down the engine.

Logged Event Codes

The event and the time of the event

Determine the conditions for the event. The

conditions will include the engine rpm and the

load.

Determine if there are any systems that were

installed by the dealer or by the customer that

could cause the event.

Determine whether any additional events

occurred.

When the ECM generates an event code, the ECM

logs the code in permanent memory. The ECM has

an internal diagnostic clock. The ECM will record

the following information when an event code is

generated:

• The hour of the first occurrence of the code

• The hour of the last occurrence of the code

• The number of occurrences of the code

Logged events are listed in chronological order. The

most recent event code is listed first.

This information can be helpful for troubleshooting

intermittent faults. Logged codes can als o be used to

review the performance of the engine.

Clearing Event Codes

2.

3.

4.

Verify that the fault is not due to normal engine

operation. Verify that the fault is not due to error of

the operator.

Narrow the probable cause. Consider the operator

information, the conditions of operation, and the

his tory of the engine.

Perform a visual inspection. Inspect the following

items:

• Fuel supply

• Oil level

• Oil supply

• Wiring

• Connectors

A code is cleared from memory when one of the

following conditions occur:

• The code does not recur for 100 hours.

• A new code is logged and there are already ten

codes in memory. In this case, the oldest code is

cleared.

• The service technician manually clears the code.

Always clear logged event codes after investigating

and correcting the fault which generated the code.

Be sure to check the connectors. This is very

important for faults that are intermittent. Refer to

Troubleshooting, “Electrical Connectors - Inspect”.

If these steps do not resolve the fault, identify the

procedures in this manual that best describe the

event. Check each probable cause according to the

tests that are recommended.

Trip Points for the Monitoring

System

The monitoring system determines the level of action

that is taken by the ECM in response to a condition

that can damage the engine. When any of these

conditions occur, the appropriate event code will trip.

KENR6224

Table 11 contains the conditions that are monitored

and the default trip points for each condition.

Each condition has an associated parameter. The

settings for each parameter can be viewed with the

the engine components. If the engine oil level is

low, add engine oil in order to obtain the correct

engine oil level.

B. Check the following faults that may occur to the

engine oil pump:

a. Air leakage in the supply side of the oil pump

will also cause cavitation and loss of oil

pressure. Check the supply side of the oil pump

and make necessary repairs.

tube that is drawing in air. Check the joints of the

oil pickup tube for cracks or a damaged O-ring

seal.

D. If the engine oil bypass valves are held in the

open position, a reduction in the oil pressure can

be the result. This may be due to debris in the

engine oil. If the engine oil bypass valves are

stuck in the open position, remove each engine

oil bypass valve and clean each bypass valve in

order to correct this fault. You must also clean

each bypass valve bore.

E. Engine oil that is c ontaminated with fuel or coolant

will cause low engine oil pressure. High engine

oil level in the crankcase can be an indication of

contamination.

F.  Excessive clearance at engine bearings will

cause low engine oil pres sure. Check the engine

components for excessive bearing clearance.

G. An oil line that is open, broken, or disconnected

E361-3 (Shutdown)

• The engine will be shut down.

Troubleshooting:

There may be a fault in the engine cooling system.

Check the Engine’s Cooling System

A. Verify that the cooling sy stem is filled to the proper

lev el. If the coolant level is too low, air will get into

the cooling system. Air in the cooling system will

cause a reduction in coolant flow.

B. Check the radiator or the heat exchanger for a

restriction to coolant flow.

a. Check for debris or damage between the fins

of the radiator core. Debris between the fins of

the radiator core restricts air flow through the

radiator core.

b. Check internally for debris, dirt, or deposits on

the radiator core. Debris, dirt, or deposits will

restrict the flow of coolant through the radiator.

C. Check the concentration of the Extended Life

Coolant (ELC). Make sure that the coolant

mixture meets recommendations. Refer to the

Operation and Maintenance Manual, “Fluid

Recommendations”.

E. Check the water pump. A water pump with a

damaged impeller does not pump enough coolant.

Remove the water pump and check for damage

to the impeller.

F.  If the cooling system for this application is

equipped with a fan, check the operation of the

fan. A fan that is not turning at the correct speed

can cause improper air speed across the radiator

core. The lack of proper air flow across the

radiator c ore can cause the coolant not to cool to

the proper temperature differential.

G. Check for air in the cooling system. Air can enter

the cooling s ystem in different ways. The most

common causes of air in the cooling system are

the incorrect filling of the cooling system and

combustion gas leakage into the cooling system.

Combustion gas can get into the system through

inside cracks, a damaged cylinder head, or a

damaged cylinder head gasket.

H. Check the cooling system hoses and clamps.

Damaged hoses with leaks can normally be seen.

Hoses that have no visual leaks can soften during

operation. The soft areas of the hose can become

kink ed or crushed during operation. These areas

of the hose can restrict the coolant flow. Hoses

become soft and/or get cracks after a period of

time. The inside of a hose can deteriorate, and the

loose particles of the hos e can restrict the coolant

flow.

I.  If the cooling system for this application is

equipped with an expansion tank, check the s hunt

line for the expansion tank. The shunt line must be

submerged in the expansion tank. A res triction of

the shunt line from the expansion tank to the inlet

of the jacket water pump will c ause a reduction in

water pump efficiency. A reduction in water pump

efficiency will result in low coolant flow.

J. If the cooling system for this application

is equipped with an aftercooler, check the

aftercooler. A restriction of air flow through the air

to air aftercooler c an cause overheating. Check

for debris or deposits which would prevent the free

flow of air through the aftercooler.

K. Check for a restriction in the air inlet system. A

restriction of the air that is coming into the engine

can cause high cylinder temperatures. High

cylinder temperatures cause higher than normal

temperatures in the cooling system.

L. Check for a restriction in the exhaust system.

A restriction of the air that is coming out of the

engine can c ause high cylinder temperatures.

72

Troubleshooting Section

KENR6224

M. Consider high ambient temperatures. When

ambient temperatures are too high for the rating

of the cooling system, there is not enough of a

temperature difference between the ambient air

and c oolant temperatures.

N. Consider high altitude operation. The cooling

capability of the cooling system is reduced at

higher altitudes. A pressurized cooling system that

is large enough to keep the coolant from boiling

must be used.

O. The engine may be running in the lug condition.

When the load that is applied to the engine is

too large, the engine will run in the lug condition.

When the engine is running in the lug condition,

engine rpm does not increase with an increase of

fuel. This lower engine rpm causes a reduction in

coolant flow through the s ystem.

A thorough inspection of the cooling system revealed

a fault.

Results:

• OK – There is a fault in the cooling sy stem.

Repair: Repair the fault. Ensure that the repair

eliminates the fault.

soften during operation. The soft areas of the

hose can become kinked during operation.

These areas can also collapse during

operation. These areas of the hose can restrict

difference between the ambient air and coolant

temperatures.

b. Determine the cause of the high air

temperature. Correct the situation, when

possible.

C. Check for High Inlet Air Restriction and/or

High Altitude Operation

a. When inlet air pressure is low, the turbocharger

works harder in order to achieve the desired

inlet manifold pressure. This increases inlet air

temperature.

b. Measure the inlet air pressure while the engine

is operating under load. For specific data, refer

to the Technical Data Sheets for the engine.

c. Check for plugged air filters. Check for

obstructions to the air inlet. A restriction of
