      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 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

      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.

      properly.

      Engine Speed/Timing Sensor  – An  engine

      speed/timing sensor is a  hall effect switch that

      provides a digital signal  to the ECM. The ECM

      interprets this signal as the crankshaft position and

      the engine speed. Two sensors are used to provide

      the speed and timing signals to the ECM. The primary

      sensor is associated with the crankshaft  and the

      secondary sensor is associated with the camshaft.

      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

      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.

      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.

      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.

      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.

      Two short jumper wires are needed  to check the

      continuity of some wiring harness circuits by shorting

      two adjacent terminals together in a connector. A

      long extension wire may also be needed to check the

      continuity of some wiring harness circuits.

      Total Tattletale  – The total tattletale is the  total

      number of changes to all the parameters  that are

      stored in the ECM.

      Optional Service Tools

      Table 2 lists the optional service tools that  can be

      used when the engine is serviced.

      Wait To Start Lamp  – This lamp is included in the

      cold starting aid circuit in order to indicate when the

      wait to start period is active.  The lamp will go off

      when the engine is ready to be started.  The glow

      plugs may not have deactivated.

      Note: On a cold start, when the Electronic Control

      Module (ECM) determines that it is necessary for the

      glow plugs to be activated prior to starting, a lamp

      output will indicate that the operator needs to “Wait

      to Start”. It is possible that starting aids may be used

      during the cranking of the engine. Starting aids may

      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

      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.

      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.

      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.

      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

      . 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.

      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:

      •  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

      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.

      programmed into the “Number of  Switch Inputs”

      parameter. “Open” signifies that the switch is in the

      OFF position. “Ground” signifies that the switch is

      in the ON position.

      required.

      Exchanging Electronic Unit Injectors

      Exchanging electronic unit  injectors can help

      determine if a combustion problem is in the electronic

      unit injector or in the cylinder. If two electronic unit

      injectors that are currently installed in the engine are

      exchanged between cylinders, the injector codes

      must also be exchanged. Press  the “Exchange”

      button at the bottom of the “Injector Trim Calibration”

      screen on the electronic service tool. Select the two

      electronic unit injectors that will be exchanged and

      press the “OK” button. The tattletale for the electronic

      unit injectors that were exchanged will increase by

      one.

      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
