            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

            •  Relays

            •  Electronic Control Module (ECM)

            •  Software (flash file)

            •  Wiring

            •  Aftertreatment ID module

            NOTICE

            •  Sensors

            Do not use electrical components (ECM or ECM sen-

            sors)  or electronic  component grounding  points  for

            grounding the welder.

            •  Actuators

            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.

            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.

            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.

            Event Code  – An event code may be activated

            in order to indicate an abnormal engine operating

            condition. These codes usually indicate a mechanical

            problem instead of an electrical system problem.

            16  – The signal from the device is high (moderate

            severity).

            17  – The signal from the device is low (least severe).

            Exhaust Back Pressure Valve  – The exhaust back

            pressure valve regulates the gas pressure  in the

            exhaust system. The valve can restrict the flow of

            exhaust gases in order to increase the exhaust back

            pressure. An increase in exhaust back pressure will

            increase the temperature of the exhaust gases. The

            increase in temperature will improve the process that

            burns off the soot in the CDPF.

            18  – The signal from the device is low (moderate

            severity).

            19  – There is an error in the data from the device.

            31  – The device has failed and the engine has shut

            down.

            Flash File  – This file is  software that is inside

            the ECM. The  file contains all the instructions

            (software) for the ECM and  the file contains the

            performance maps for a specific engine. The file may

            be reprogrammed through flash programming.

            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.

            Flash Programming  – Flash programming is the

            method of programming or updating an ECM with

            an electronic service tool over the data link instead

            of replacing components.

            High Pressure Fuel Pump  – This pump is a device

            that supplies fuel under pressure  to the fuel rail

            (high-pressure fuel rail).

            FRC  – See “Fuel Ratio Control”.

            High Pressure Fuel Rail  – See “Fuel Rail”.

            Fuel Pump  – See “High Pressure Fuel Pump”.

            Injector Trim Codes  – Injector trim codes are codes

            that contain 30 characters. The codes are supplied

            with new injectors. The code is  input through the

            electronic service tool into the ECM. The injector trim

            codes compensate for variances in manufacturing

            of the electronic unit injector and for the life of  the

            electronic unit injector.

            Fuel Rail  – This item is sometimes referred to as the

            High Pressure Fuel Rail. The fuel rail supplies fuel to

            the electronic unit injectors. The high-pressure fuel

            pump and the fuel rail pressure sensor work with the

            ECM in order to maintain the desired fuel pressure

            in the fuel rail.  This pressure is determined by

            calibration of the engine in order to enable the engine

            to meet emissions and performance requirements.

            Intake Manifold Air Temperature Sensor  –  The

            intake manifold air temperature sensor detects the

            air temperature in the intake manifold. The  ECM

            monitors the air temperature and other data in the

            intake manifold in order to adjust injection timing and

            other performance functions.

            Fuel Rail Pressure Sensor  – The fuel rail pressure

            sensor sends a signal to the ECM that is dependent

            on the pressure of the fuel in the fuel rail.

            Fuel Ratio Control (FRC)  – The FRC is a limit that

            is based on the control of the ratio of the fuel to air.

            The FRC is used for purposes of emission control.

            When the ECM senses a higher  intake manifold

            air pressure (more air into the cylinder),  the FRC

            increases the FRC Limit (more fuel into the cylinder).

            Intake Manifold Pressure Sensor  – The Intake

            Manifold Pressure Sensor measures the pressure

            in the intake manifold. The pressure in the  intake

            manifold may be different to the pressure  outside

            the engine (atmospheric pressure). The difference

            in pressure may be caused  by an increase in air

            pressure by a turbocharger.

            Full Load Setting (FLS) – The FLS is the parameter

            that represents the fuel system adjustment.  This

            adjustment is made  at the factory in  order to

            fine-tune the fuel system. This parameter must be

            programmed.

            Integrated Electronic Controls  – The engine is

            designed with the electronic controls as a necessary

            part of the system.  The engine will not operate

            without the electronic controls.

            Full Torque Setting  (FTS) –  The FTS is the

            parameter that represents the adjustment for  the

            engine torque. This adjustment is made at the factory

            in order to fine-tune the fuel system. This adjustment

            is made with the  FLS. This parameter must be

            programmed.

            J1939 CAN Data Link  – This data link is a  SAE

            standard diagnostic communications data link that is

            used to communicate between the ECM and other

            electronic devices.

            Logged Diagnostic Codes  – Logged diagnostic

            codes are codes which are stored in the  memory.

            These codes are an indicator of possible causes for

            intermittent problems. Refer to the term “Diagnostic

            Trouble Codes” for more information.

            Glow Plug  – The glow plug is an optional starting aid

            for cold conditions. One glow plug is installed in each

            combustion chamber in order to improve the ability of

            the engine to start. The ECM uses information from

            the engine sensors to determine when the glow plug

            relay must provide power to each glow plug. Each

            of the glow plugs then provides a hot surface in the

            combustion chamber in order to vaporize the mixture

            of air and fuel. The vaporization improves ignition

            during the compression stroke of the cylinder.

            NOx Reduction System  – The NOx Reduction

            System recycles a portion of the exhaust gases back

            into the inlet air. The recirculation reduces the oxides

            of nitrogen (NOx) in the exhaust gases. The recycled

            exhaust gas passes through a cooler before being

            introduced into the inlet air.

            Glow Plug Relay  – The glow plug relay is controlled

            by the ECM in order to provide high current to  the

            glow plugs.

            OEM  – OEM is an abbreviation for the  Original

            Equipment Manufacturer.  The OEM is  the

            manufacturer of the machine or the vehicle that uses

            the engine.

            Troubleshooting Section

            Open Circuit  – An open circuit is a condition that is

            caused by an open switch, or by an electrical wire

            or a connection that is broken. When this condition

            exists, the signal o, r the supply voltage can no longer

            reach the intended destination.

            Parameter  – A parameter is a value or a limit that is

            programmable. A parameter helps determine specific

            characteristics or behaviors of the engine.

            Password  – A password 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  – See “Flash File”.

            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.

            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.

            Signal  – The signal is a voltage or a waveform that

            is used in order to transmit information typically from

            a sensor to the ECM.

            Wastegate  – The wastegate is a  device in a

            turbocharged engine that controls the  maximum

            boost pressure that is provided to the inlet manifold.

            Suction Control Valve (SCV) – The SCV is a control

            device in the high-pressure fuel pump. The  valve

            controls the pressure in the fuel rail by varying the

            amount of fuel that enters the chambers in the pump.

            Wastegate Regulator  – The wastegate regulator

            controls the pressure in the  intake manifold to a

            value that is determined by the ECM. The wastegate

            regulator provides the interface between the ECM

            and the mechanical system. The wastegate regulates

            intake manifold pressure to the desired value that is

            determined by the software.

            Supply Voltage – The supply voltage is a continuous

            voltage that is supplied to a component. The power

            may be generated by the ECM or the power may be

            battery voltage that is supplied by the engine wiring.

            serial port of PC (1).

            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.

            Note: The Adapter Cable Assembly (4) is required to

            connect to the USB port on computers that are not

            equipped with an RS232 serial port.

            Flashing  – The lamp will be  flashing when a

            “warning” or a “warning and derate” is active. This

            includes low oil pressure.

            3.  Connect cable (4) between the “DATA LINK” end

            of communication adapter (3) and the service tool

            connector.

            On  – The lamp will be on when the shutdown level

            has been reached. The “Shutdown” lamp will also

            be on.

            4.  Place the keyswitch in the ON position.  If the

            Electronic Service Tool and the communication

            adapter do not communicate with the Electronic

            Control Module (ECM), refer to the  diagnostic

            procedure Troubleshooting, “Electronic Service

            Tool DoesNot Communicate”.

            Wait to Start Lamp

            Lamp check  – When the keyswitch is turned to ON,

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

            then go off unless “Wait to Start” is active.

            On  – The lamp is on during a “Wait to Start” period.

            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.

            Indicator Lamps

            On  – The lamp will come on when a low oil pressure

            event is detected. The  “Warning” lamp and the

            “Shutdown” lamp may also come on.

            Four lamps are available as options. The “Shutdown”

            lamp and the “Warning” lamp will normally be installed

            in the application. Dedicated optional lamps for other

            items may also be installed. The remaining optional

            lamps are “Wait to start” and “Low oil pressure”.

            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

            and logged diagnostic codes.

            Color of Lamps

            Shutdown Lamp

            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.

            Flash Codes

            The “Flash Code” feature is used to flash the code

            of all active diagnostic codes and logged diagnostic

            codes.

            The sequence for the flash code is started by moving

            the keyswitch to “Off” and then moving the keyswitch

            to “On” twice within a period of three seconds. After

            a delay of 2 seconds, the “Shutdown” lamp will flash

            once for a period of half a second. This sequence

            indicates the start of the active  fault codes. After

            a further delay of 2 seconds,  the “Warning” lamp

            will flash repeatedly in order to indicate the active

            diagnostic codes. Each flash will be  on for half a

            second and off for 300 milliseconds. The “Warning”

            lamp will remain off for 2 seconds between each digit

            of a code. If there is more than one active diagnostic

            code, the “Shutdown” lamp will go off for 2 seconds.

            The lamp will then come on  for a period of half a

            second. The “Warning” lamp will go off for a period of

            2 seconds before starting the next code. If there are

            no active diagnostic codes, the “Warning” lamp will

            flash the code “551”. Refer to Troubleshooting Guide,

            “No Diagnostic Code Detected”.

            As an example, an active diagnostic code of “21” is

            indicated by the “Warning” lamp coming on for 500

            ms, then off for 300 ms, then on for 500 ms, then off

            for 2000 ms, then on for 500 ms and then off.

            Timing of the flash  codes

            After all of the active diagnostic codes have  been

            displayed, the “Shutdown” lamp will  go off for 2

            seconds. The “Shutdown” lamp will flash  twice in

            order to indicate the start of the sequence that will

            display the logged diagnostic codes. The process for

            flashing logged diagnostic codes is identical to the

            process for flashing active diagnostic codes.

            Note: If there are no logged codes then the  “551”

            code should be flashed again.

            Troubleshooting Section

            After all of the  codes have been displayed, the

            “Shutdown” lamp will  flash 3 times in order  to

            indicate that there are no further codes. Cycling the

            keyswitch twice within a period of  3 seconds will

            start the process again. All codes will be displayed in

            ascending numerical order.

            Note: If an ECM is to be used as a test ECM, “Test

            ECM Mode” must be selected  on the electronic

            service tool before the  engine serial number is

            entered.

            Use the electronic service tool to read the parameters

            in the suspect ECM.  Record the parameters in

            the suspect ECM. Install the flash file into the new

            ECM. After the ECM is installed on the engine, the

            parameters must be programmed into the new ECM.

            Refer to the Troubleshooting Guide, “Diagnostic

            Code Cross Reference” for the diagnostic code that

            relates to the flash code.

            Note: Flash codes are always sent  in ascending

            numerical order.

            Note: When a new ECM is not available, an ECM

            can be used from an engine that is not  in service.

            The ECM must  have the same serial number

            suffix. Ensure that the replacement ECM and  the

            part number for the flash  file match the suspect

            ECM. Be sure to record the  parameters from the

            replacement ECM. Use the “Copy Configuration ECM

            Replacement” function in the electronic service tool.

            NOTICE

            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.

            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.

            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.

            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.

            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

            •  Rerate the engine.

            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

            Note: The injector code is located on the electronic

            unit injector.

            The injector code is loaded into the ECM.

            The number of these non-programmable parameters

            that are visible  depends on the value  that is

            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.

            9.  Repeat the procedure for each  cylinder, as

            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.

            Lower Position Limit

            This parameter is the minimum throttle percentage

            that will be interpreted by the ECM as zero throttle.

            This parameter is used with the value of initial lower

            position limit to make an allowance for manufacturing

            tolerances between different pedals.

            (9) Upper Position Limit (Default=85)

            All analog throttles and digital throttles can have an

            idle validation switch. If this parameter is programmed

            to “Yes”, the ECM will look for this switch input on pin

            J1:22 for Idle Validation Switch 1 (IVS1) and J1:40

            for Idle Validation Switch 2 (IVS2).

            (10) Upper Diagnostic Limit (Default=95)

            Analog throttles and digital throttles require additional

            programming. If a multi-position switch is selected,

            additional parameters must  be programmed.

            Refer to the Troubleshooting Guide, “Multiposition

            Switch Setup”. If an  analog throttle or a digital

            throttle is selected, the following parameters can be

            programmed into the ECM.

            Threshold

            This parameter is the minimum throttle percentage

            that should be detected  by the ECM in normal

            operation when the pedal is in the “off” position. A

            value below this limit will generate  a short circuit

            diagnostic code. The  range of this diagnostic

            detection area is from 0 percent to the programmed

            value for the lower position limit.

            This parameter is the minimum throttle percentage

            that will be detected by the ECM when the IVS is ON

            (Closed).

            If the ECM detects a throttle percentage below this

            value with the idle validation switch OFF  (Open),

            a fault code will be generated and the  engine will

            remain at idle.

            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

            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

            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 “Throttle Lock Feature Installation Status”  is

            used to turn on the throttle lock features. When this

            parameter is changed to “Installed”, the following

            parameters are active and the parameters can be

            programmed.

            The “Throttle Lock Increment Speed Ramp Rate”

            parameter is the rate of engine acceleration when the

            PTO switch is held in the ACCELERATE position. If

            The “Monitoring Mode Derates” parameter controls

            the amount of derate that  is associated with the

            engine monitoring feature. When this  feature is

            enabled and a diagnostic code with an appropriate

            FMI is detected, the engine will be derated.

            The “Throttle Lock Decrement Speed Ramp Rate”

            parameter is the rate of engine deceleration when

            the PTO switch is held in the DECELERATE position.

            If this parameter is set to “0”, the feature is turned off.

            The “Throttle Lock Engine Set Speed  Increment”

            parameter controls the increase in engine  speed

            when the  PTO switch is briefly  operated to

            ACCELERATE. If this parameter is set to “0”,  the

            feature is turned off.

            The “Limp Home Desired Engine Speed” parameter

            is the maximum speed of the engine when the engine

            The “Engine Acceleration Rate” parameter is  the

            acceleration rate for  the engine under normal

            operating conditions. A setting of “0” disables this

            function.

            The “Throttle Lock Engine Set Speed Decrement”

            parameter controls the decrease in engine speed

            when the  PTO switch is briefly  operated to
