The 1104 models RF, RH, RK and 1106 model VK engines were designed for electronic control. The engines include an Electronic Control Module (ECM), a fuel injection pump that is electronically controlled, and a collection of engine sensors. The ECM controls the engine operating parameters through the software within the ECM and the inputs from the various sensors. The software contains parameters that control the engine operation. The parameters include all of the operating maps and customer selected parameters.

The electronic system consists of the Electronic Control Module (ECM), the engine sensors, and the Machine Interface Connector (MIC). The ECM is the computer. The personality module is the software for the computer. The personality module contains the operating maps. The operating maps define the following characteristics of the engine:

The electronic controls determine the injection timing and the amount of fuel that is delivered to the cylinders. These decisions are based on the actual conditions and the desired conditions at any given time.

The governor compares the desired engine speed to the actual engine speed. The actual engine speed is determined through the crankshaft position sensor. If the desired engine speed is greater than the actual engine speed, the governor injects more fuel in order to increase engine speed.

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:

At start-up, the ECM determines the top dead center position of the number 1 cylinder from the speed/timing sensor in the fuel injection pump. The ECM decides when fuel injection should occur relative to the top dead center position. The ECM provides the signal to the fuel injection pump spill valve which stops fuel flow to the low pressure side. The ECM then forces fuel to flow to the fuel injector nozzles at the desired time. The ECM adjusts timing for the best engine performance, the best fuel economy and the best control of exhaust emissions. Actual timing cannot be viewed with an electronic service tool. Also, the desired timing cannot be viewed with an electronic service tool.

The personality module inside the ECM sets certain limits on the amount of fuel that can be injected. The FRC Limit is a limit that is based on intake manifold air pressure and engine rpm. The FRC Limit is used to control the air/fuel ratio in order to control the engine ’ s exhaust emissions. When the ECM senses a higher intake manifold air pressure, the ECM increases the FRC Limit. A higher intake manifold air pressure indicates that there is more air in the cylinder. When the ECM increases the FRC Limit, the ECM allows more fuel into the cylinder.

The Rated Fuel Limit is a limit that is based on the power rating of the engine and on the engine rpm. The Rated Fuel Limit enables the engine power and torque outputs to conform to the power and torque curves of a specific engine model.

When the ECM detects an engine problem, the ECM generates a diagnostic code. Also, the ECM logs the diagnostic code in order to indicate the time of the problem ’ s occurrence. The ECM also logs the number of occurrences of the problem. There are two types of diagnostic fault codes. There are fault codes and event codes.

Diagnostic fault codes are provided in order to indicate that an electrical problem or an electronic problem has been detected by the ECM. In some cases, the engine performance can be affected when the condition that is causing the code exists. More frequently, the operator cannot detect any difference in the engine performance.

If the operator indicates that a performance problem occurs, the diagnostic code may indicate the cause of the problem. Use either a laptop computer or a hand held diagnostic tool to access the diagnostic codes. The problem should then be corrected.

If the operator does not indicate a problem with the engine performance and a diagnostic code is logged by the ECM. This situation indicates that the ECM detected an abnormal engine condition, but the abnormal condition did not affect engine performance. In this situation, the system has no faults except when either of the following conditions exist:

Diagnostic event codes are used to indicate that some operational problem has been detected in the engine by the ECM. This does not indicate an electronic malfunction.

Certain parameters that affect the engine operation may be changed with electronic service tools. The parameters are stored in the ECM, and the parameters are protected from unauthorized changes by passwords. These parameters are System Configuration Parameters.

System Configuration Parameters are set at the factory. System Configuration Parameters affect emissions or power ratings within the engine. Factory passwords must be obtained and factory passwords must be used to change the System Configuration Parameters.

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 an electronic service tool may change System Configuration Parameters. System Configuration Parameters affect the power rating or the emissions.

Active Diagnostic Code – An active diagnostic code alerts the operator or the service technician that an electronic system malfunction is currently present. Refer to the term “ Diagnostic Code ” in this glossary.

Alternating Current (AC) – Alternating current is an electric current that reverses direction at a regular interval that is reoccurring.

Before Top Dead Center (BTC) – BTDC is the 180 degrees of crankshaft rotation before the piston reaches the top dead center position in the normal direction of rotation.

The difference between the turbocharger outlet pressure and atmospheric pressure is commonly referred to as boost pressure. The sensor for the intake manifold air pressure measures the amount of boost.

Breakout Harness – The breakout harness is a test harness that is designed to connect into the engine harness. This connection allows a normal circuit operation and the connection simultaneously provides a Breakout T in order to measure the signals.

Bypass Circuit – A bypass circuit is a circuit that is used as a substitute circuit for an existing circuit. A bypass circuit is typically used as a test circuit.

CAN Data Link – The CAN Data Link is a serial communications port that is used for communication with other microprocessor based devices. In this application, the CAN Data Link connects the ECM to the Electronic Fuel Injection Pump.

and for cold engine operation that includes timing that is retarded and low idle that is raised. This mode is used for engine protection, reduced smoke emissions and faster warm up time.

Communication Adapter Tool – The communication adapter provides a communication link between the ECM and the Electronic Service Tool.

Coolant Level Sensor – The coolant level sensor detects the absence or presence of coolant at the probe. The sensor then sends a signal to the ECM.

Coolant Temperature Sensor – The coolant temperature sensor detects the engine coolant temperature for cold mode operation and for Engine Monitoring.

Data Link – The Data Link is a serial communication port that is used for communication with other microprocessor based devices.

Desired Engine Speed – The desired engine speed is input to the electronic governor within the ECM. The electronic governor uses the signal from the throttle position sensor, the engine speed/timing sensor, and other sensors in order to determine the desired engine speed.

Diagnostic Code – A diagnostic code is sometimes referred to as a fault code. These codes indicate an electronic system malfunction.

Diagnostic Lamp – A diagnostic lamp is sometimes called the check engine light. The diagnostic lamp is used to warn the operator of the presence of an active diagnostic code.

Digital Sensor Return – The common line (ground) from the ECM is used as ground for the digital sensors.

Digital Sensors – Digital sensors produce a pulse width modulated signal. Digital sensors are supplied with +8 VDC from the ECM.

Digital Sensor Supply – The +8 VDC supply from the ECM is used in order to power the digital sensors.

Direct Current (DC) – Direct current is the type of current that flows consistently in only one direction.

DT, DT Connector, or Deutsch DT – This is a type of connector that is used on Perkins engines. The connectors are manufactured by Deutsch.

control is a complete electronic system. The electronic engine control monitors the engine operation under all conditions. The electronic engine control also controls the engine operation under all conditions.

Component Identifier (CID) – The CID is a number that identifies the specific component of the electronic control system that has experienced a diagnostic code.

Electronic Service Tool – The electronic service tool allows a computer (PC) to communicate with the ECM.

control computer of the engine. The ECM provides power to the electronics. The ECM monitors data that is input from the sensors of the engine. The ECM acts as a governor in order to control the speed and the power of the engine.

Engine Monitoring – Engine Monitoring is the part of the electronic engine control that monitors the sensors. This also warns the operator of detected problems.

Engine Oil Pressure Sensor – The engine oil pressure sensor measures engine oil pressure. The sensor sends the signal to the ECM.

Engine Speed/Timing Sensor – The engine speed/timing sensor provides a variable amplitude and pulse width modulated signal to the ECM. The ECM interprets this signal as the crankshaft position and the engine speed.

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.

Failure Mode Identifier (FMI) – This identifier indicates the type of failure that has been experienced by the component. The FMI has been adopted from the SAE practice of J1587 diagnostics.

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.

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).

Fuel Temperature Sensor – The fuel temperature sensor detects the fuel temperature. The ECM monitors the fuel temperature and the ECM adjusts the calculated fuel rate accordingly.

Full Load Setting (FLS) – The FLS is the number that represents the fuel system adjustment. This adjustment is made at the factory in order to fine tune the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. This parameter must be programmed.

Harness – The harness is the bundle of wiring (loom) that connects all components of the electronic system.

Intake Manifold Air Temperature Sensor – The intake manifold air temperature sensor detects the air temperature in the intake manifold. The ECM monitors the air temperature and other data in the intake manifold in order to adjust injection timing and other performance functions.

Intake Manifold Pressure Sensor – The air pressure in the intake manifold may be different to the air pressure outside the engine (atmospheric pressure). This difference in air pressure can be caused by variable air velocity within the manifold. The difference in pressure can also be caused by an increase in air pressure by a turbocharger (if equipped). The sensor for the intake manifold air pressure measures the difference between atmospheric pressure and the air pressure in the intake manifold.

Integrated Electronic Controls – The engine is designed with the electronic controls as a necessary part of the system. The engine will not operate without the electronic controls.

J1939 CAN Data Link – This data link is a SAE diagnostic communications data link that is used to communicate between the ECM and the electronic service tool.

Logged Diagnostic Codes – Logged diagnostic codes are codes which are stored in the memory. These codes are meant to be an indicator of possible causes for intermittent problems. Refer to the term “ Diagnostic Code ” in this glossary for more information.

MAB – This is a Bosch acronym for the fuel shutoff inside the “ VPM30 ” Fuel Injection Pump. The MAB is a signal wire from the ECM to the Fuel Injection Pump.

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 or the supply voltage can no longer reach the intended destination.

Parameter – A parameter is a value or a limit that is programmable. This helps determine specific characteristics or behaviors of the engine.

Full Torque Setting (FTS) – The FTS is similar to the full load setting. This parameter must be programmed.

characters or a group of alphanumeric characters that is designed to restrict access to parameters. The electronic system requires correct passwords in order to change some parameters (Factory Passwords). Refer to Troubleshooting, “ Factory Passwords ” for more information.

Personality Module – This module is inside the ECM. The module contains all the instructions (software) for the ECM and the module contains the performance maps for a specific engine. The personality module may be reprogrammed through flash programming.

Power Cycled – Power cycled happens when power to the ECM is cycled: ON, OFF, and ON. Power cycled refers to the action of cycling the keyswitch from any position to the OFF position, and to the START/RUN position.

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 total “ TIME OFF ” can be varied. This ratio is also referred to as a duty cycle.

Short Circuit – A short circuit is a condition that has an electrical circuit that is inadvertently connected to an undesirable point. An example of a short circuit is a wire which rubs against a vehicle frame and this rubbing eventually wears off the wire insulation. Electrical contact with the frame is made and a short circuit results.

Signal – The signal is a voltage or a waveform that is used in order to transmit information typically from a sensor to the ECM.

Supply Voltage – The supply voltage is a constant voltage that is supplied to a component in order to provide the electrical power that is required for the component to operate. The power may be generated by the ECM or the power may be battery voltage that is supplied by the engine wiring.

System Configuration Parameters – System configuration parameters are parameters that affect emissions and/or operating characteristics of the engine.

Throttle Position – The throttle position is the interpretation by the ECM of the signal from the throttle position sensor or the throttle switch.

Rated Fuel Limit – This term indicates the maximum allowable fuel position (longest injection pulse). This position will produce rated power for this engine configuration.

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.

Sensor – A sensor is a device that is used to detect a change in pressure, temperature, or mechanical movement. The information that is detected is converted into an electrical signal.

Throttle Position Sensor – The throttle position sensor is an electronic sensor that is connected to an accelerator pedal or a hand lever. This sensor sends a PWM signal to the ECM that is used to calculate desired engine speed.

Throttle Switch – The throttle switch sends a signal to the ECM that is used to calculate desired engine speed.

Top Dead Center – Top dead center refers to the crankshaft position when the engine piston position is at the highest point of travel. The engine must be turned in the normal direction of rotation in order to reach this point.

Total Tattletale – The total tattletale is the total number of changes to all the parameters that are stored in the ECM.

Voltage Load Protection Module ( “ VLPM ” ) – The “ VLPM ” monitors the voltage of the electronic system. The “ VLPM ” will eliminate any high voltage conditions that occur. The “ VLPM ” will protect the fuel injection pump from any high voltage conditions that could damage the pump.

Electronic Service Tools are designed to help the service technician with the diagnosis and repair of electronic engines. Several tools are available to assist the service technician.

Some of the included Diagnostic Functional Tests in this manual require two short jumper wires. The jumper wires are used to check the continuity of some wiring harness circuits by shorting two adjacent terminals together in a connector.

Some engine applications are equipped with Indicator Lamps. Indicator lamps can be used as a diagnostic aid. There are two lamps. One lamp has an orange lens and the other lamp has a red lens.

current operational status of the engine. The indicator lamps can also be used to indicate that the engine has a fault. This system is automatically operated via the ignition switch.

Each lamp will be illuminated in a combination of ways in order to identify the engine ’ s operational status. The lamps will also be illuminated in a combination of ways to indicate if the engine has a fault. These combinations of illuminated lamps have the following meanings:

When the ignition switch is turned ON, the lamps will be illuminated for 2 seconds. The lamps are then OFF unless the cold starting aid is required.

The following combinations of lamp status may also be exhibited when the engine is either running or when the engine has been shut down automatically.

Unless there is a fault, the engine monitoring system will not illuminate the indicator lamps while the engine is being cranked. For example if there is a lack of lubricating oil pressure after the start delay is exceeded. This type of fault will cause the stop lamp for the engine to be illuminated.

engine to shut down or the engine has exceeded the conditions for a derate. There is also an electrical fault.

The indicator lamps can be used to identify an active code by flashing in a sequence that will identify the active code. The active code that is flashed by the indicator lamps is only the component identifier (CID). The indicator lamps cannot identify the fault with the component. The active code that is flashed by the indicator lamps is not a Failure Mode Identifier (FMI).

When the Flash Code feature is activated the indicator lamps will flash the codes of all active codes. Activation of the indicator lamps is achieved by cycling the keyswitch OFF and ON twice within 3 seconds.

An active CID with two digits will be flashed in the following sequence. There will be a number of flashes. The number of flashes will equal the first digit. There will be a delay before a second number of flashes. The second number of flashes will equal the second digit. For example, a CID code of 41 will be four flashes, a delay and the one flash. A three digit CID code will have two delays between the sequence of flashes. A four digit CID code will have three delays between the sequence of flashes.

After one active code has been identified there will be a delay of 5 seconds before the next active code is flashed.

The sequence of flashing the active codes may be restarted at any time by reactivating the cycling of the keyswitch.

The engine is equipped with an Electronic Control Module (ECM). The ECM contains no moving parts. Follow the troubleshooting procedures in this manual in order to be sure that replacing the ECM will correct the problem. Verify that the suspect ECM is the cause of the problem.

Note: Ensure that the ECM is receiving power and that the ECM is properly grounded before replacement of the ECM is attempted. Refer to Troubleshooting, “ Electrical Power Supply Circuit ­Test ” .

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. Flash the personality module into the test ECM. Program the parameters for the test ECM. The parameters must match the parameters in the suspect ECM. Refer to the following test steps for details. If the test ECM resolves the problem, reconnect the suspect ECM. Verify that the problem returns. If the problem returns, replace the ECM.

Use the electronic service tool to read the parameters in the suspect ECM. Record the parameters in the suspect ECM. The personality module can be flashed into the new ECM. After the ECM is installed on the engine, the parameters must be programmed into the new ECM.

Note: When a new ECM is not available, you may need to remove an ECM from an engine that is not in service. The ECM must have the same serial number suffix. Ensure that the replacement ECM and the Personality Module Interlock Code 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.

parameters on the “ Main Configuration ” screen. Also, record all of the parameters on the “ Throttle Configuration ” screen and on the “ Mode Configuration ” screen.

Note: If the parameters cannot be read, the parameters must be obtained elsewhere. Some parameters are stamped on the engine information plate, but most parameters must be obtained from the factory.

installed correctly. The rubber grommets are used to protect the ECM from excessive vibration. The ECM should be able to drift in the rubber grommets.

to clear the rating interlock in the Personality Module. 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.

successful, use the “ Copy Configuration, ECM Replacement ” function to load the configuration file into the ECM.

Diagnostic Code – When a problem with the electronic system is detected, the ECM generates a diagnostic code. This indicates the specific problem with the circuitry.

Active Code – An active diagnostic code indicates that an active problem has been detected. Active codes require immediate attention. Always service active codes prior to servicing logged codes.

Logged Code – Every generated code is stored in the permanent memory of the ECM. The codes are logged.

Event Code – An event code is generated by the detection of an abnormal engine operating condition. For example, an event code will be generated if the oil pressure is too low. In this case, the event code indicates the symptom of a problem.

Logged codes may not indicate that a repair is needed. The problem may have been temporary. The problem may have been resolved since the logging of the code. If the system is powered, it is possible to generate an active diagnostic code whenever a component is disconnected. When the component is reconnected, the code is no longer active. Logged codes may be useful to help troubleshoot intermittent problems. Logged codes can also be used to review the performance of the engine and the electronic system.

The Electronic Control Module (ECM) has the ability to detect problems with the electronic system and with engine operation. When a problem is detected, a code is generated. An alarm may also be generated. There are two types of codes:

The wiring diagrams are revised periodically. The wiring diagrams will change with updates to the wiring harness. For the most current information, always check the revision number of the diagram. Use the diagram with the latest revision number.

Note: Each terminal end of the J1939 CAN data link must be connected with a 120 ohm terminating resistor.

Perkins identifies all wires with eleven solid colors. The circuit number is stamped on the wire at a 25 mm (1 inch) spacing. Table 11 lists the wire colors and the color codes.

For example, a wire identification of F702-GN on the schematic would signify a green wire with the circuit number F702. F702-GN identifies the power supply for the 8 V throttle sensor.

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 shows if a parameter has been changed.

Note: The old interlock code is required to change the interlock code on a used ECM. A new interlock code is also required to change the interlock code on a used ECM.

Note: The factory passwords may only be used for one programming session. A different set of factory passwords will be required after you exit the electronic service tool screen. A different set of passwords will be required to change information on another electronic service tool screen.

Passwords are part of a security system that helps to prevent unauthorized reprogramming of certain parameters. Passwords prevent unauthorized erasing of logged events. Passwords allow the factory to control access to engine calibration parameters. Passwords allow the customer to control access to certain programmable engine parameters.

Factory passwords are required to clear any event code. Factory passwords are required to change certain parameters such as Full Load Setting. The factory passwords restrict changes to authorized personnel. When the correct factory passwords have been entered, the changes can then be made.

In order to obtain the proper factory passwords, certain information must be given to an authorized Perkins distributor. Since the factory passwords contain alphabetic characters, the electronic service tool can be used to perform this function. In order to obtain the factory passwords, proceed as if you already have the factory passwords. At some point, if the factory passwords are actually needed, the electronic service tool will request the factory passwords and the electronic service tool will display the information that is required to obtain the factory passwords.

Customer Passwords allow the customer to restrict access to parameters that are programmable by the customer. The customer passwords cannot be longer than eight characters. The customer has the option of entering one or two customer passwords.

Note: If the owner loses the owner ’ s customer passwords, the owner will not be able to program parameters that are protected by customer passwords. By using factory passwords, one can read customer passwords. Then use those customer passwords to program parameters that have been protected by customer passwords.

The electronic service tool can be utilized to flash a new personality module into the ECM. The flash is accomplished by transferring the data from a PC to the ECM.

3. When an ECM has been detected, the “ ECM Selector ” window will appear. Select the appropriate ECM that needs to be flashed and press “ Browse ” .

4. The flash files are located on a disk drive and in a directory. Select the correct disk drive and the correct directory from “ Drives ” and “ Directories ” on the electronic service tool.

5. Select the correct file from the list of flash files. Read the “ File Info ” and the “ Description ” in order to verify that the correct file is selected. Select “ OK ” .

the “ Service ” menu in order to determine the parameters that require programming. Look under the “ Tattletale ” column. All of the parameters should have a tattletale of 1 or more. If a parameter has a tattletale of 0, program that parameter.

If you receive any error messages during flash programming, click on the “ Cancel ” button in order to stop the process. Access the information about the “ ECM Summary ” under the “ Information ” menu. Make sure that you are flashing the correct file for your engine.
