    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.

    i04155807

    System Overview

    4.  Disconnect all electronic components from

    the wiring harnesses.  Include the following

    components:

    The engine has an electronic control system. The

    system also monitors the Diesel Particulate Filter

    (DPF) and the NOx Reduction System (NRS).

    •  Electronic components for the driven equipment

    •  ECM

    The control system  consists of the following

    components:

    •  Sensors

    •  Electronically controlled valves

    •  Relays

    •  Electronic Control Module (ECM)

    •  Software (flash file)

    •  Wiring

    •  Aftertreatment ID module

    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.

    Troubleshooting Section

    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.

    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.

    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.

    Illustration 7

    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.

    be used if the engine has previously been started.

    The “Wait to Start” lamp will not be active in  these

    conditions.

    The “Shutdown” lamp and the “Warning” lamp can

    also be used to indicate a diagnostic code by use of

    the “Flash Code” feature. The “Flash Code” feature

    can be used to indicate all active diagnostic codes

    and logged diagnostic codes.

    Typically, the “Shutdown” lamp is colored red and the

    “Warning” lamp is colored amber. The other lamps

    are optional.

    Lamp check  – When the keyswitch is turned to ON,

    the lamp will come on for 2 seconds. The lamp will

    then go off unless there is an active warning.

    Flashing  – The lamp will be flashing when a derate

    is active or when a derate  is present because of

    an active diagnostic code. An example of an active

    diagnostic code is “System Voltage High”.

    On  – The lamp will be on when the shutdown level

    in the engine protection strategy has been reached.

    The “Warning” lamp will also be on.

    Troubleshooting Section

    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.

    g01779334

    Illustration 9

    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.

    This document is printed from SPI². Not for RESALE


     

    KENR9116-01

    21

    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.

    i04319696

    Replacing the ECM

    NOTICE

    If the flash file and engine application are not matched,

    engine damage may result.

    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.

    This document is printed from SPI². Not for RESALE


     

    22

    KENR9116-01

    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.

    i04215569

    Sensors and  Electrical

    Connectors

    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.

    The Electronic Control Module (ECM)  and most

    of the engine sensors are located on  the left side

    of the engine. For the 1204E-E44 engine, refer to

    Illustration 10. For the remaining sensors that are

    attached to the 1204E-E44 engine, refer to Illustration

    12. For the 1206E-E66 engine, refer to Illustration 14

    . For the remaining sensors that are attached to the

    1206E-E66 engine, refer to Illustration 16. For the

    sensors and components on the Clean Emissions

    Module (CEM), refer to Illustration 18.

    Perform the “Fuel System Verification Test”.

    11. Check for logged diagnostic codes. Factory

    passwords are required to clear logged events.

    i03951470

    Self-Diagnostics

    Note: In the following illustrations, some components

    have been removed in order to improve visibility.

    The Electronic Control Module (ECM) can 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 diagnostic trouble code

    is generated. This code conforms to the SAE J1939

    standard. An alarm may also be generated.

    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”.

    Factory passwords are required to perform each of

    the following functions:

    Troubleshooting Section

    •  Program a new Electronic  Control Module

    (ECM).

    Note: You must have the engine serial number  in

    order to search for the part number of the flash file.

    When an ECM is replaced, the system configuration

    parameters must be programmed into the  new

    ECM. A new ECM will allow these parameters to

    be programmed once without factory passwords.

    After the initial programming, some parameters are

    protected by factory passwords.

    2.  Connect the electronic service  tool to the

    diagnostic connector.

    3.  Turn the keyswitch to the ON position. Do not start

    the engine.

    4.  Select “WinFlash” from the “Utilities” menu on the

    electronic service tool.

    Rerating may require changing the interlock code,

    which is protected by factory passwords.

    Note: If WinFlash will not  communicate with the

    ECM, refer to Troubleshooting, “Electronic Service

    Tool Will Not Communicate with ECM”.

    •  Unlock parameters.

    5.  Flash program the flash file into the ECM.

    Factory passwords are  required in order to

    unlock certain system configuration parameters.

    Refer to Troubleshooting, “System Configuration

    Parameters”.

    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.

    Installing Injector Codes

    Upper Diagnostic Limit

    This parameter is the minimum throttle percentage

    that is detected by the ECM in normal operation when

    the pedal is in the maximum position. A value above

    this limit will generate an  open circuit diagnostic

    code. The range of this diagnostic detection area is

    from the programmed value of the upper  position

    limit to 100 percent.

    Physical Position Enabled

    If “Yes” is selected  from the drop-down menu,

    the ECM sets the  engine rpm to the value that

    is programmed into the  “Engine Speed” for the

    configuration of the switches that is defined for that

    Physical Position.

    Multiposition Switch Setup

    Logical Position

    The Logical Position is the order that is required by

    the user for a unique Physical Position.

    Note: The multi-position throttle switch can only be

    enabled if the optional PTO switches are not installed.

    Table 32

    The multi-position throttle switch  is an optional

    throttle input. A maximum of four switches can be

    used. Four switches will allow  a maximum of 16

    speeds to be selected.

    Engine Speed (in RPM)

    If an optional intermediate engine speed switch is

    installed, the multi-position throttle switch can have a

    maximum of three switches. Three switches will allow

    a maximum of eight speeds to be selected.

    The “Engine Speed” is the programmed engine rpm

    for a particular position of the multi-position throttle

    switch.

    When the multi-position switch is selected  as the

    “Throttle Type” on the “Throttle Configuration Screen”

    of the electronic service tool, additional information

    is required.

    If the ECM  detects a switch combination that

    has been configured as “No”, a  fault code will be

    generated. In this situation, the ECM will ignore the

    multi-position switch until the keyswitch is  cycled

    through OFF and ON.

    Number of Switch Inputs

    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.
