Troubleshooting Section
The 1106D engine was designed for electronic
control. The engine has an Electronic Control Module
(ECM), a fuel rail pump and electronic unit injectors.
All of these items are electronically controlled. There
arealsoanumb
er of engine sensors. Turbocharged
engines can be equipped with an electronically
controlled wastegate for the turbocharger. The ECM
controls the engine operating parameters through
the software within the ECM and the inputs from the
various sensors. The software contains parameters
that control the engine operation. The parameters
include all of the operating maps and customer
selected parameters.
The electronic system consists of the ECM, the
engine sensors and inputs from the parent machine.
The ECM is the computer. The personality module
is the software for the computer. The personality
module defines the following characteristics of the
engine:
•Engine power
•Torque curves
•Engine speed (rpm)
•Engine Noise
•Smoke and Emissions
Engine Speed Governor
The ECM determines the injection timing, the amount
of fuel that is delivered to the cylinders and the intake
manifold pressure if an electronically controlled
wastegate is installed on the turbocharger. These
decisions are based on the actual conditions and the
desired conditions at any given time.
The governor has software that compares the desired
engine speed to the actual engine speed. The actual
engine speed is determined through the primary
speed/timing sensor and the secondary speed/timing
sensor. If the desired engine speed is greater than
the actual engine speed, the governor injects more
fuel in order to increase engine speed.
Timing Considerations
Fuel injection timing is determined by the ECM after
considering input from the following components:
•Engine coolant temperature sensor
•The sensor for the intake manifold air temperature
•The sensor for the intake manifold pressure
•Speed/timing sensors
•Speed control device
At start-up, the ECM determines the top center
position of the number 1 cylinder from the secondary
speed/timing sensor in the fuel rail pump. The ECM
decides when fuel injection should occur relative to
the top center position. The ECM optimizes engine
performance by control of each of the electronic
unit injectors so that the required amount of fuel is
injected at the precise point of the engine's cycle. The
electronic unit injectors are supplied high pressure
fuel from the fuel rail. The ECM also provides the
signal to the solenoid in the fuel rail pump. The
solenoid in the fuel rail pump controls a valve in the
fuel rail pump. This valve controls the pressure in
the fuel rail. Fuel that is not required for the engine
is diverted away from the fuel rail pump back to the
fuel tank.
The ECM adjusts injection timing and fuel pressure
for the best engine performance, the best fuel
economy and the best control of exhaust emissions.
Theactualtimingcanbeviewedwithanelectronic
service tool. Also, the desired timing can be viewed
with an electronic service tool.
Fuel Injection
The personality module inside the ECM sets certain
limits on the amount of fuel that can be injected.
The Fuel Ratio Control Limit is a limit that is based
on intake manifold air pressure and engine rpm. The
FRC Limit is used to control the air/fuel ratio in order
to control the engine's exhaust emissions. When the
ECM senses a higher intake manifold air pressure,
the ECM increases the FRC Limit. A higher intake
manifold air pressure indicates that there is more air
in the cylinder. When the ECM increases the FRC
Limit, the ECM allows more fuel into the cylinder.
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 personality module and these
limits cannot be changedby the operator.
Diagnostic Codes
When the ECM detects an electronic system problem,
the ECM generates a diagnostic code. Also, the ECM
logs the diagnostic code in order to indicate the time
of the problem's occurrence. The ECM also logs the
number of occurrences of the problem. Diagnostic
codes are provided in order to indicate that the ECM
has detected an electrical problem or an electronic
problem with the engine control system. In some
cases, the engine performance can be affected when
the condition that is causing the code exists.

KENR6201-01 7
Troubleshooting Section
If the operator indicates that a performance problem
occurs, the diagnostic code may indicate the cause
of the problem. Use the electronic service tool to
access the diagnostic codes. The problem should
then be corrected.
Event Codes
Event Codes are used to indicate that the ECM has
detected an abnormal engine operating condition.
The ECM will log the occurrence of the event code.
This does not indicate an electrical malfunction
or an electronic malfunction. For example, if the
temperature of the coolant in the engine is higher
than the permitted limit, then the ECM will detect the
condition. The ECM will then log an event code for
the condition.
Programmable Parameters
Certain parameters that affect the engine operation
may be changed with electronic service tools.
The parameters are stored in the ECM, and the
parameters are protected from unauthorized changes
by passwords. These parameters are System
Configuration Parameters.
System Configuration Parameters are set at the
factory. System Configuration Parameters affect
emissions or power ratings within the engine. Factory
passwords must be obtained and factory passwords
must be used to change the System Configuration
Parameters.
Passwords
System Configuration Parameters are protected by
factory passwords. Factory passwords are calculated
onaco
mputer system that is available only to
Perkins distributors. Since factory passwords contain
alphabetic characters, only an electronic service
tool may change System Configuration Parameters.
System Configuration Parameters affect the power
rating or the emissions.
Refer to Troubleshooting, “Programming Parameters”
and Troubleshooting, “Factory Passwords”.

Troubleshooting Section
FRC – See “Fuel Ratio Control”.
Fuel Pump – See “Fuel Rail Pump”.
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 fuel rail 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.
FuelRailPr
essure Sensor – Thefuelrailpressure
sensor sends an electronic signal to the ECM that is
dependent on the pressure of the fuel in the fuel rail.
Fuel Rail Pump – This item is sometimes referred
toastheHighPressureFuelRailPump.Thisisa
device that supplies fuel under pressure to the fuel
rail (high pressure fuel rail).
Fuel Rail Pump Solenoid Valve – This is sometimes
referred to as the High Pressure Fuel Rail Pump
Solenoid Valve. This is a control device in the high
pressure fuel rail pump. The ECM controls the
pressure in the fuel rail by using this valve to divert
excess fuel from the pump to the fuel tank.
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).
Full Load Setting (FLS) – The FLS is the number
that represents the fuel system adjustment. This
adjustment is made at the factory in order to fine tune
thefuelsystem.Thecorrectvalueforthisparameter
is stamped on the engine information ratings plate.
This parameter must be programmed.
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 such as the engine temperature
to determine when the glow plug relay must provide
power to each glow plug. Each of the glow plugs
then provides a very hot surface in the combustion
chamber in order to vaporize the mixture of air and
fuel. This improves ignition during the compression
stroke of the cylinder.
Glow Plug Relay – The glow plug relay is controlled
by the ECM in order to provide high current to the
glow plugs that are used in the starting aid system.
Harness – The harness is the bundle of wiring
(loom) that connects all components of the electronic
system.
Hertz (Hz) – Hertz is the measure of electrical
frequency in cycles per second.
High Pressure Fuel Rail Pump – See “Fuel Rail
Pump”.
High Pressure Fuel Rail Pump Solenoid Valve –
See “Fuel Rail Pump Solenoid Valve”.
High Pressure Fuel Rail – See “Fuel Rail”.
Injector Codes – The injector codes or injector trim
codes are numeric codes or alphanumeric codes
that are etched or stamped on individual electronic
unit injectors. These codes are used to fine tune the
fuel delivery.
Injector Trim Files – Injector trim files are
downloaded from a disk to the ECM. The injector trim
files compensate for variances in manufacturing of
the electronic unit injector. The serial number for the
electronic unit injector must be obtained in order to
retrieve the correct injector trim file.
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.
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 (if equipped).
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.
J1939 CAN Data Link – This data link is a SAE
standard diagnostic communications data link that
is used to communicate between the ECM and the
electronic devices.
Logged Diagnostic Codes – Logged diagnostic
codes are codes which are stored in the memory.
These codes are meant to be an indicator of possible
causes for intermittent problems. Refer to the
term “Diagnostic Code” in this glossary for more
information.
OEM – OEM is an abbreviation for the Original
Equipment Manufacturer. This is the manufacturer of
the machine or the vehicle that uses the engine.

caused by an open switch, or by an electrical wire
or a connection that is broken. When this condition
exists, the signal or the supply voltage can no longer
reach the intended destination.
Parameter – A parameter is a value or a limit that
is programmable. This helps determine specific
characteristics or behaviors of the engine.
Password – Apassword is a group of numeric
characters or a group of alphanumeric characters
that is designed to restrict access to parameters. The
electronic system requires correct passwords in order
to change some parameters (Factory Passwords).
Refer to Troubleshooting, “Factory Passwords” for
more information.
Personality Module – This module is software
that is inside the ECM. The module contains all the
instructions (software) for the ECM and the module
contains the performance maps for a specific engine.
The personality module may be reprogrammed
through flash programming.
Power Cycling – Power cycling refers to the action
of cycling the keyswitch from any position to the OFF
position, and to the START/RUN position.

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 a short
circuit results.
Signal – The signal is a voltage or a waveform that
is used in order to transmit information typically from
asensortotheECM.
SpeedDemandInput –The speed demand input is
a signal that is sent to the ECM in order to calculate
desired engine speed.
Supply Voltage – The supply voltage is a continuous
voltage that is supplied to a component in order to
provide the electrical power that is required for the
component to operate. The power may be generated
by the ECM or the power may be battery voltage that
is supplied by the engine wiring.
System Configuration Parameters – System
configuration parameters are parameters that affect
emissions and/or operating characteristics of the
engine.

Tattletale – Certain parameters that affect the
operation of the engine are stored in the ECM.
These parameters can be changed by use of the
electronic service tool. The tattletale logs the number
of changes that have been made to the parameter.
ThetattletaleisstoredintheECM.
Throttle Position – The throttle position is the
interpretation by the ECM of the signal from the
speed controller.
Timing Calibration – The timing calibration is the
adjustment of an electrical signal. This adjustment is
made in order to correct the timing error between the
camshaft and the engine speed/timing sensors or
between the crankshaft and the engine speed/timing
sensors.
Top Center Position – The top center position refers
to the crankshaft position when the engine piston
position is at the highest point of travel. The engine
must be turned in the normal direction of rotation in
order to reach this point.
Total Tattletale – The total tattletale is the total
number of changes to all the parameters that are
stored in the ECM.
Wastegate – This is a device in a turbocharged
engine that controls the maximum boost pressure
that is provided to the inlet manifold.
Wastegate Regulator (if equipped) – 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 that
regulates intake manifold pressure to the desired
value that is determined by the software.

Replacing the ECM
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 open-
ing any compartment or disassembling any compo-
nent containing fluids.
Dispose of all fluids according to local regulations and
mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
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 problem. Verify that the suspect ECM is the
cause of the problem.
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.
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 problem, reconnect the suspect
ECM. Verify that the problem returns. If the problem
returns, replace the ECM.
Note: If an ECM is intended 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.
Note: When a new ECM is not available, an ECM
canbeusedfroman engine that is not in service.
The ECM must have the same serial number
suffix. Ensure that the replacement ECM and the
part number fortheflash 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
If the flash file and engine application are not matched,
engine damage may result.
Perform the following procedure in order to replace
the ECM.
1. Connect the electronic service tool to the
diagnostic connector.
2. Use the “Copy Configuration ECM Replacement”
function from the electronic service tool. If the
“Copy Configuration” is successful, proceed to
Step 4. If the “Copy Configuration” failed, proceed
to Step 3.
Note: Record any Logged Faults and Events for your
records.
3. Record the following parameters:
•Record all of the parameters on the
“Configuration” screen.
•Record all of the parameters on the “Throttle
Configuration” screen.
•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.
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
thePTMIdataonthePerkinsintranet.
4. Remove power from the ECM.
5. Remove the ECM. Refer to Disassembly and
Assembly, “Electronic Control Module - Remove
and Install”.
6. Install the replacement ECM. Refer to Disassembly
and Assembly, “Electronic Control Module -
Remove and Install”.
7. If the replacement ECM is intended to be used
as a test ECM, select “Test ECM Mode” on the
electronic service tool.

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.
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 toolisfirst connected. Activating the Test
ECM mode will also clear the rating interlock.
10. Use the electronic service tool to program the
parameters. Perform the following procedure.
a. If the “CopyConfiguration” procedure was
successful, use the “Copy Configuration, ECM
Replacement” function to load the configuration
file into the ECM.
Note: During the following procedure, factory
passwords may be required.
b. If the “Copy Configuration” procedure failed,
configure the parameters individually. The
parameters should match the parameters from
step 3.
Perform the “Fuel System Verification Test”.
11. Check for logged diagnostic codes. Factory
passwords are required to clear logged events.
i03538621
Self-Diagnostics
The Electronic Control Module (ECM) has the ability
to detect faults in the electronic system and with
engine operation. A self-diagnostic check is also
performed whenever power is applied to the ECM.
When a fault is detected, a code is generated. An
alarm may also be generated. There are two types
of codes:
•Diagnostic codes
•Event codes
Diagnostic Code – When a fault in the electronic
system is detected, the ECM generates a diagnostic
code. This indicates the specific fault in 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 by the control
system. Active codes require immediate attention.
Always service active codes prior to servicing logged
codes.
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.
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 code
indicates the symptom of a fault.
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 the electronic system.
