Welding Precaution
Correct welding procedures are necessary in order to
avoid damage to the following components:
• Electronic Control Module (ECM) on the engine
• Clean Emissions Module (CEM)
• Sensors
g01143634
Illustration 1
• Associated components
Service welding guide (typical diagram)
Components for the driven equipment should also be
considered. When possible, remove the component
that requires welding. When welding on an engine
that is equipped with an ECM and removal of the
component is not possible, the following procedure
must be followed. This procedure minimizes the risk
to the electronic components.
5. When possible, connect the ground clamp for
the welding equipment directly to the engine
component that will be welded. Place the clamp
as close as possible to the weld. Close positioning
reduces the risk of welding current damage to the
engine bearings, to the electrical components,
and to other components.
1. Stop the engine. Remove the electrical power
from the ECM.
6. Protect the wiring harnesses from welding debris
and/or from welding spatter.
2. Ensure that the fuel supply to the engine is turned
off.
7. Use standard welding procedures to weld the
materials together.
3. Disconnect the negative battery cable from the
battery. If a battery disconnect switch is installed,
open the switch.

System Operation
Engine Governor
The ECM governs the engine. The ECM determines
the timing, the injection pressure, and the amount
of fuel that is delivered to each cylinder. These
factors are based on the actual conditions and on the
desired conditions at any given time during starting
and operation.
The governor uses the throttle position sensor to
determine the desired engine speed. The governor
compares the desired engine speed to the actual
engine speed. The actual engine speed is determined
through interpretation of the signals that are received
by the ECM from the engine speed/timing sensors. If
the desired engine speed is greater than the actual
engine speed, the governor injects more fuel in order
to increase engine speed.

KENR9116-01
Troubleshooting Section
Fuel Injection
The ECM sends a high voltage signal to the injector
solenoids in order to energize the solenoids. By
controlling the timing and the duration of the high
voltage signal, the ECM can control the following
aspects of injection:
• Injection timing
• Fuel delivery
The flash file inside the ECM establishes certain
limits on the amount of fuel that can be injected.
The FRC Fuel Limit is a limit that is based on the
intake manifold pressure. The FRC Fuel Limit is used
to control the air/fuel ratio for control of emissions.
When the ECM senses a higher intake manifold
pressure, the ECM increases the FRC Fuel Limit. A
higher intake manifold pressure indicates that there
is more air in the cylinder. When the ECM increases
the FRC Fuel Limit, the ECM allows more fuel into
the cylinder.
g01860934
Illustration 6
Typical example
The Rated Fuel Limit is a limit that is based on the
power rating of the engine and on the engine rpm.
The Rated Fuel Limit is like the rack stops and 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 a specific engine rating. All of these limits are
determined at the factory. These limits cannot be
changed.
The desired engine speed is typically determined by
one of the following conditions:
• The position of the throttle
• The desired engine speed in Power Take-Off (PTO)
Timing Considerations
Once the governor has determined the amount of
fuel that is required, the governor must determine
the timing of the fuel injection. Fuel injection timing is
determined by the ECM after considering input from
the following components:
Customer Parameters and Engine Speed
Governing
A unique feature with electronic engines is customer
specified parameters. These parameters allow the
owner of the machine to fine-tune the ECM for engine
operation. Fine-tuning the ECM allows the machine
owner to accommodate the typical usage of the
machine and the power train of the machine.
• Coolant temperature sensor
• Intake manifold air temperature sensor
• Intake manifold pressure sensor
• Barometric pressure sensor
Many of the customer parameters provide additional
restrictions on the actions that will be performed by
the ECM in response to input from the operator. The
PTO Top Engine Limit is an engine rpm limit that is
used by the ECM to limit the fuel during operation of
the PTO. The ECM will not fuel the injectors above
this rpm.
The ECM adjusts timing for optimum engine
performance and fuel economy. Actual timing and
desired timing cannot be viewed with the electronic
service tool. The ECM determines the location of
top center of the number one cylinder from the
signals that are provided by the engine speed/timing
sensors. The ECM determines when injection should
occur relative to top center position. The ECM then
provides the signal to the injector at the desired time.
Some parameters are intended to notify the operator
of potential engine damage (engine monitoring
parameters). Some parameters enhance fuel
economy (machine speed, engine speed limit,
and idle shutdown). Other parameters are used to
enhance the engine installation into the machine.
Other parameters are used to provide operating
information to the owner of the machine.

Other ECM Functions for
Performance
“Lifetime Total Engine Revolutions” is the total
number of revolutions that have been completed by
the engine crankshaft.
The ECM can also provide enhanced control of the
engine for machine functions such as controlling the
cooling fan. Refer to Troubleshooting, “Configuration
Parameters” for supplemental information about the
systems that can be monitored by the ECM in order
to provide enhanced machine performance, fuel
economy, and convenience for the operator.
“Average Load Factor” provides relative engine
operating information. “Average Load Factor”
compares actual operating information of the engine
to the maximum engine operation that is available.
“Average Load Factor” is determined by using “Total
Max Fuel”, “Total Idle Fuel”, and “Total Fuel”. All of
these parameters are available with the electronic
service tool. These parameters are available within
the menu for “Current Totals”.
ECM Lifetime Totals
The ECM maintains total data of the engine for the
following parameters:
Programmable Parameters
Certain parameters that affect engine operation
may be changed with the electronic service tool.
The parameters are stored in the ECM, and the
parameters are protected from unauthorized changes
by passwords. These parameters are either system
configuration parameters or customer parameters.
• “Total Operating Hours”
• “Engine Lifetime Hours”
• “Total Idle Time”
• “Total Idle Fuel”
System configuration parameters are set at the
factory. System configuration parameters affect
emissions or power ratings within an engine family.
Factory passwords must be obtained and factory
passwords must be used to change the system
configuration parameters.
• “Total Fuel”
• “Total Max Fuel”
• “Engine Starts”
Customer parameters are variable. Customer
parameters affect the following characteristics within
the limits that are set by the factory, by the monitoring
system, and by PTO operation:
• “Lifetime Total Engine Revolutions”
• “Average Load Factor”
The “Total Operating Hours” is the operating hours of
the engine. The operating hours do not include the
time when the ECM is powered but the engine is not
running.
• Rpm ratings
• Power ratings
Customer passwords may be required to change
customer specified parameters.
The “Engine Lifetime Hours” is the number of hours
when electrical power has been applied to the
engine. These hours will include the time when the
ECM is powered but the engine is not running.
Some of the parameters may affect engine operation
in an unusual way. An operator might not expect
this type of effect. Without adequate training,
these parameters may lead to power complaints
or performance complaints even though the
performance of the engine is to the specification.
“Total Idle Time” and “Total Idle Fuel” can include
operating time when the engine is not operating
under a load.
Fuel Information can be displayed in US gallons or
in liters.
Refer to Troubleshooting, “Configuration Parameters”
for additional information on this subject.
“Total Fuel” is the total amount of fuel that is
consumed by the engine during operation.
Passwords
“Total Max Fuel” is the maximum amount of fuel that
could have been consumed by the engine during
operation.
System configuration parameters are protected by
factory passwords. Factory passwords are calculated
on a computer system that is available only to
Perkins Distributors. Since factory passwords contain
alphabetic characters, only the electronic service
tool may change system configuration parameters.
System configuration parameters affect the power
rating family or emissions.
“Engine Starts” is the total number of times when the
engine has been started.

High Pressure Fuel Rail – See “Fuel Rail”.
Fuel Pump – See “High Pressure Fuel Pump”.
Injector Trim Codes – Injector trim codes are codes
that contain 30 characters. The codes are supplied
with new injectors. The code is input through the
electronic service tool into the ECM. The injector trim
codes compensate for variances in manufacturing
of the electronic unit injector and for the life of the
electronic unit injector.
Fuel Rail – This item is sometimes referred to as the
High Pressure Fuel Rail. The fuel rail supplies fuel to
the electronic unit injectors. The high-pressure fuel
pump and the fuel rail pressure sensor work with the
ECM in order to maintain the desired fuel pressure
in the fuel rail. This pressure is determined by
calibration of the engine in order to enable the engine
to meet emissions and performance requirements.
Intake Manifold Air Temperature Sensor – The
intake manifold air temperature sensor detects the
air temperature in the intake manifold. The ECM
monitors the air temperature and other data in the
intake manifold in order to adjust injection timing and
other performance functions.
Fuel Rail Pressure Sensor – The fuel rail pressure
sensor sends a signal to the ECM that is dependent
on the pressure of the fuel in the fuel rail.
Fuel Ratio Control (FRC) – The FRC is a limit that
is based on the control of the ratio of the fuel to air.
The FRC is used for purposes of emission control.
When the ECM senses a higher intake manifold
air pressure (more air into the cylinder), the FRC
increases the FRC Limit (more fuel into the cylinder).
Intake Manifold Pressure Sensor – The Intake
Manifold Pressure Sensor measures the pressure
in the intake manifold. The pressure in the intake
manifold may be different to the pressure outside
the engine (atmospheric pressure). The difference
in pressure may be caused by an increase in air
pressure by a turbocharger.
Full Load Setting (FLS) – The FLS is the parameter
that represents the fuel system adjustment. This
adjustment is made at the factory in order to
fine-tune the fuel system. This parameter must be
programmed.
Integrated Electronic Controls – The engine is
designed with the electronic controls as a necessary
part of the system. The engine will not operate
without the electronic controls.
Full Torque Setting (FTS) – The FTS is the
parameter that represents the adjustment for the
engine torque. This adjustment is made at the factory
in order to fine-tune the fuel system. This adjustment
is made with the FLS. This parameter must be
programmed.
J1939 CAN Data Link – This data link is a SAE
standard diagnostic communications data link that is
used to communicate between the ECM and other
electronic devices.
Logged Diagnostic Codes – Logged diagnostic
codes are codes which are stored in the memory.
These codes are an indicator of possible causes for
intermittent problems. Refer to the term “Diagnostic
Trouble Codes” for more information.
Glow Plug – The glow plug is an optional starting aid
for cold conditions. One glow plug is installed in each
combustion chamber in order to improve the ability of
the engine to start. The ECM uses information from
the engine sensors to determine when the glow plug
relay must provide power to each glow plug. Each
of the glow plugs then provides a hot surface in the
combustion chamber in order to vaporize the mixture
of air and fuel. The vaporization improves ignition
during the compression stroke of the cylinder.
NOx Reduction System – The NOx Reduction
System recycles a portion of the exhaust gases back
into the inlet air. The recirculation reduces the oxides
of nitrogen (NOx) in the exhaust gases. The recycled
exhaust gas passes through a cooler before being
introduced into the inlet air.
Glow Plug Relay – The glow plug relay is controlled
by the ECM in order to provide high current to the
glow plugs.
OEM – OEM is an abbreviation for the Original
Equipment Manufacturer. The OEM is the
manufacturer of the machine or the vehicle that uses
the engine.

Rated Fuel Limit – The rated fuel limit is a limit that
is based on the power rating of the engine and on the
engine rpm. The Rated Fuel Limit enables the engine
power and torque outputs to conform to the power
and torque curves of a specific engine model. These
limits are in the flash file and these limits cannot be
changed.
Pressure Limiting Valve (PLV) – The PLV is a valve
in the fuel rail that prevents excessive pressure. The
PLV will reduce the pressure to a safe level that will
limit engine operation but the reduced pressure will
not stop the engine.
Primary Speed/Timing Sensor – This sensor
determines the position of the crankshaft during
engine operation. If the primary speed/timing
sensor fails during engine operation, the secondary
speed/timing sensor is used to provide the signal.
Reference Voltage – Reference voltage is a
regulated voltage and a steady voltage that is
supplied by the ECM to a sensor. The reference
voltage is used by the sensor to generate a signal
voltage.
Pulse Width Modulation (PWM) – The PWM is a
signal that consists of pulses that are of variable
width. These pulses occur at fixed intervals. The ratio
of “TIME ON” versus “TIME OFF” can be varied. This
ratio is also referred to as a duty cycle.
Relay – A relay is an electromechanical switch. A
flow of electricity in one circuit is used to control the
flow of electricity in another circuit. A small current or
voltage is applied to a relay in order to switch a much
larger current or voltage.
Secondary Speed/Timing Sensor – This sensor
determines the position of the camshaft during engine
operation. If the primary speed/timing sensor fails
during engine operation, the secondary speed/timing
sensor is used to provide the signal.
Sensor – A sensor is a device that is used to
detect the current value of pressure or temperature,
or mechanical movement. The information that is
detected is converted into an electrical signal.
Short Circuit – A short circuit is a condition that has
an electrical circuit that is inadvertently connected to
an undesirable point. An example of a short circuit
is a wire which rubs against a vehicle frame and
this rubbing eventually wears off the wire insulation.
Electrical contact with the frame is made and results
in a short circuit.

is used in order to transmit information typically from
a sensor to the ECM.
Wastegate – The wastegate is a device in a
turbocharged engine that controls the maximum
boost pressure that is provided to the inlet manifold.
Suction Control Valve (SCV) – The SCV is a control
device in the high-pressure fuel pump. The valve
controls the pressure in the fuel rail by varying the
amount of fuel that enters the chambers in the pump.
Wastegate Regulator – The wastegate regulator
controls the pressure in the intake manifold to a
value that is determined by the ECM. The wastegate
regulator provides the interface between the ECM
and the mechanical system. The wastegate regulates
intake manifold pressure to the desired value that is
determined by the software.
Supply Voltage – The supply voltage is a continuous
voltage that is supplied to a component. The power
may be generated by the ECM or the power may be
battery voltage that is supplied by the engine wiring.

Flash Codes
The “Flash Code” feature is used to flash the code
of all active diagnostic codes and logged diagnostic
codes.
The sequence for the flash code is started by moving
the keyswitch to “Off” and then moving the keyswitch
to “On” twice within a period of three seconds. After
a delay of 2 seconds, the “Shutdown” lamp will flash
once for a period of half a second. This sequence
indicates the start of the active fault codes. After
a further delay of 2 seconds, the “Warning” lamp
will flash repeatedly in order to indicate the active
diagnostic codes. Each flash will be on for half a
second and off for 300 milliseconds. The “Warning”
lamp will remain off for 2 seconds between each digit
of a code. If there is more than one active diagnostic
code, the “Shutdown” lamp will go off for 2 seconds.
The lamp will then come on for a period of half a
second. The “Warning” lamp will go off for a period of
2 seconds before starting the next code. If there are
no active diagnostic codes, the “Warning” lamp will
flash the code “551”. Refer to Troubleshooting Guide,
“No Diagnostic Code Detected”.
As an example, an active diagnostic code of “21” is
indicated by the “Warning” lamp coming on for 500
ms, then off for 300 ms, then on for 500 ms, then off
for 2000 ms, then on for 500 ms and then off.

Timing of the flash codes
After all of the active diagnostic codes have been
displayed, the “Shutdown” lamp will go off for 2
seconds. The “Shutdown” lamp will flash twice in
order to indicate the start of the sequence that will
display the logged diagnostic codes. The process for
flashing logged diagnostic codes is identical to the
process for flashing active diagnostic codes.
Note: If there are no logged codes then the “551”
code should be flashed again.

Troubleshooting Section
After all of the codes have been displayed, the
“Shutdown” lamp will flash 3 times in order to
indicate that there are no further codes. Cycling the
keyswitch twice within a period of 3 seconds will
start the process again. All codes will be displayed in
ascending numerical order.
Note: If an ECM is to be used as a test ECM, “Test
ECM Mode” must be selected on the electronic
service tool before the engine serial number is
entered.
Use the electronic service tool to read the parameters
in the suspect ECM. Record the parameters in
the suspect ECM. Install the flash file into the new
ECM. After the ECM is installed on the engine, the
parameters must be programmed into the new ECM.
Refer to the Troubleshooting Guide, “Diagnostic
Code Cross Reference” for the diagnostic code that
relates to the flash code.
Note: Flash codes are always sent in ascending
numerical order.
Note: When a new ECM is not available, an ECM
can be used from an engine that is not in service.
The ECM must have the same serial number
suffix. Ensure that the replacement ECM and the
part number for the flash file match the suspect
ECM. Be sure to record the parameters from the
replacement ECM. Use the “Copy Configuration ECM
Replacement” function in the electronic service tool.

NOTICE
Care must be taken to ensure that fluids are contained
during performance of inspection, maintenance, test-
ing, adjusting, and repair of the product. Be prepared
to collect the fluid with suitable containers before
opening any compartment or disassembling any com-
ponent containing fluids.
Perform the following procedure in order to replace
the ECM.
1. Connect the electronic service tool to the
diagnostic connector.
Dispose of all fluids according to local regulations and
mandates.
2. Use the “Copy Configuration ECM Replacement”
function from the electronic service tool. If the
process is successful, proceed to Step 4. If the
“Copy Configuration” failed, proceed to Step 3.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note: Record any Logged Faults and Events for your
records.
The engine is equipped with an Electronic Control
Module (ECM). The ECM contains no moving parts.
Follow the troubleshooting procedures in this manual
in order to be sure that replacing the ECM will correct
the fault. Verify that the suspect ECM is the cause
of the fault.
3. Record the following parameters:
•
•
•
Record all of the parameters on the
“Configuration” screen.
Record all of the parameters on the “Throttle
Configuration” screen.
Note: Ensure that the ECM is receiving power
and that the ECM is properly grounded before
replacement of the ECM is attempted. Refer to the
schematic diagram.
Record all of the parameters on the “Mode
Configuration” screen.
• Record the serial numbers of the electronic unit
injectors. The injector serial numbers are shown
on the “Injector Trim Calibration” screen.
A test ECM can be used in order to determine if the
ECM on the engine is faulty. Install a test ECM in
place of the suspect ECM. Install the flash file with
the correct part number into the test ECM. Program
the parameters for the test ECM. 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, reconnect the suspect
ECM. Verify that the fault returns. If the fault returns,
replace the ECM.
Note: If the parameters cannot be read, the
parameters must be obtained elsewhere. Some
parameters are stamped on the engine information
plate, but most parameters must be obtained from
the PTMI data on the Perkins web site.
4. Remove power from the ECM.

Troubleshooting Section
5. Remove the ECM. Refer to Disassembly and
Assembly, “Electronic Control Module - Remove
and Install”.
Diagnostic Trouble Code – When a fault in the
electronic system is detected, the ECM generates a
diagnostic trouble code. The diagnostic trouble code
indicates the specific fault in the circuitry.
6. Install the replacement ECM. Refer to Disassembly
and Assembly, “Electronic Control Module -
Remove and Install”.
Diagnostic codes can have two different states:
• Active
7. If the replacement ECM is to be used as a test
ECM, select “Test ECM Mode” on the electronic
service tool.
• Logged
Active Code – An active diagnostic code indicates
that an active fault has been detected by the control
system. Active codes require immediate attention.
Always service active codes prior to servicing logged
codes.
8. Download the flash file.
a. Connect the electronic service tool to the
diagnostic connector.
b. Select “WinFlash” from the “Utilities” menu of
the electronic service tool.
Logged Code – Every generated code is stored
in the permanent memory of the ECM. The codes
are logged for 100 operating hours unless a code is
cleared by use of the electronic service tool.
c. Select the downloaded flash file.
9. If necessary, use the electronic service tool to clear
the rating interlock. To clear the rating interlock,
enter the factory password when the electronic
service tool is first connected. Activating the Test
ECM mode will also clear the rating interlock.
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, an active
diagnostic trouble code may be generated 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 the electronic system.
10. Use the electronic service tool to program the
parameters. Perform the following procedure.
a. If the “Copy Configuration” procedure was
successful, use the “Copy Configuration, ECM
Replacement” function to load the configuration
file into the ECM.

Programming Parameters
Note: “Test ECM Mode” can only be activated if
the engine serial number has not already been
programmed during normal operation of the ECM.
If the engine serial number is programmed and the
ECM is not in “Test ECM Mode”, the ECM can never
be used as a test ECM.
i03939853
Programming Parameters
6. Use the “Copy Configuration” feature on the
electronic service tool to program the test ECM.
The electronic service tool can be used to view
certain parameters that can affect the operation of the
engine. The electronic service tool can also be used
to change certain parameters. The parameters are
stored in the Electronic Control Module (ECM). Some
of the parameters are protected from unauthorized
changes by passwords. Parameters that can be
changed have a tattletale number. The tattletale
number is incremented whenever a parameter is
changed.
Note: If the “ECM Replacement” feature cannot be
used, program the test ECM with the values from the
“Customer Specified Parameters Worksheet” and the
values from the System Configuration Parameters.
7. Program the engine serial number into the test
ECM.
Note: The “Test ECM Mode” must be activated
before the engine serial number is programmed into
the ECM.
i03939990
Test ECM Mode
8. Verify that the test ECM eliminates the fault.
When the “Test ECM Mode” is activated, an internal
timer sets a 24 hour clock. This clock will count down
only while the ECM is powered and the keyswitch
is in the ON position. After the ECM has counted
down the 24 hour period, the ECM will exit the “Test
ECM Mode”. The parameters and the engine serial
number will be set.
“Test ECM Mode” is a feature in the software that
can be used to help troubleshoot an engine that may
have a fault in the Electronic Control Module (ECM).
This feature allows a standard ECM to be used as a
test ECM. This feature eliminates the need to stock
a test ECM.
If the test ECM eliminates the fault, the engine can
be released while the “Test ECM Mode” is still active.
1. Search for the la, test flash file for the engine.
Once an ECM has been activated in the “Test ECM
Mode”, the ECM will stay in the “Test ECM Mode”
until the timer times out. If the ECM is used as a test
ECM for more than one engine, the “Test ECM Mode”
must be reactivated. Anytime prior to the “Test ECM
Mode” timing out, the ECM can be reset to 24 hours.
Note: If a newer software version is available for the
engine, install the newest software on the suspect
ECM. If the new software does not eliminate the fault,
continue with this procedure.
2. Use the “Copy Configuration” feature on the
electronic service tool to copy the parameters
from the suspect ECM.
i03898736
Factory Passwords
Note: If the “ECM Replacement” feature cannot
be used, record the programmed values into the
“Customer Specified Parameters Worksheet”. Also
record the system configuration parameters.
NOTICE
3. Disconnect the suspect ECM. Temporarily connect
the test ECM to the engine. Do not mount the test
ECM on the engine.
Operating the engine with a flash file not designed for
that engine will damage the engine. Be sure the flash
file is correct for your engine.
4. Flash program the test ECM with the newest
software that is available.
Note: Factory passwords are provided only to
Perkins authorized distributors.
5. Start the “Test ECM Mode” on the electronic
service tool. Access the feature through the
“Service” menu. The electronic service tool will
display the status of the test ECM and the hours
that are remaining for the “Test ECM Mode”.

a. Select the engine ECM under the “Detected
ECMs”.
b. Press the “Browse” button in order to select
the part number of the flash file that will be
programmed into the ECM.
• Clear engine events and certain diagnostic
codes.
Most engine events require factory passwords in
order to clear the code from ECM memory. Clear
these codes only when you are certain that the
fault has been corrected. For example, the 190-15
Engine Overspeed requires the use of factory
passwords in order to clear the code from ECM
memory.
c. When the correct flash file is selected, press
the “Open” button.
d. Verify that the “File Values” match the
application. If the file values do not match the
application, search for the correct flash file.
e. When the correct flash file is selected, press
the “Begin Flash” button.
Since factory passwords contain alphabetic
characters, the electronic service tool must be
used to perform these functions. In order to obtain
factory passwords, proceed as if you already have
the password. If factory passwords are needed,
the electronic service tool will request the factory
passwords. The electronic service tool will display the
information that is required to obtain the passwords.
f. The electronic service tool will indicate when
the flash programming has been successfully
completed.
6. Use the electronic service tool to check for
diagnostic code 631-2. If this diagnostic code is
active and the flash file is not being installed in
order to change the engine rating, repeat this
procedure from 1. If this diagnostic code is active
and the flash file is being installed in order to
change the engine rating, factory passwords must
be obtained.

Injector Code - Calibrate
Illustration 27
Sequence for recording the injector code
The electronic service tool is used to load the injector
codes into the ECM.
Injector codes are codes that are 30 hexadecimal
characters in length that are supplied with each
injector. The code is on a plate on the top of the
injector and a card is also included in the packaging
for the injector. The code is used by the Electronic
Control Module (ECM) to balance the performance
of the injectors.
The injector codes must be loaded into the ECM if
any of the following conditions occur:
• An electronic unit injector is replaced.
• The ECM is replaced.
• Diagnostic code 268-2 is active.
• Electronic unit injectors are exchanged between
cylinders.
Note: Diagnostic code 268-2 will also become active
if the engine serial number, FLS or FTS are not
entered into the ECM.
If the ECM is replaced, the injector codes are
normally transferred to the new ECM as part of
the “Copy Configuration” procedure. If the “Copy
Configuration” procedure fails, the injector codes
must be loaded manually.

PTO mode can be configured to operate in either
Set/Resume mode or Ramp up/Ramp down mode.
Set/Resume mode allows the engine speed to be
controlled by the operator through switch inputs.
This mode allows two specific speeds to be set
and stored in the ECM. A speed can be selected
or the previously selected speed can be resumed.
Adjustments in engine speed can then be made via
the raise and lower switch inputs. Ramp up/Ramp
down mode only allows the engine speed to be raised
or lowered via switch inputs at a desired ramp rate.
The “Set” and “Resume” functions are disabled.
