cylinder head. the pump shaft is coupled to the end of the camshaft. the fuel transfer pump contains a pressure regulating valve for system over-pressure protection. a bypass valve in the pump base allows fuel to bypass the gears during hand priming. fuel flows from the transfer pump into the side of the cylinder head,&then it enters the fuel rail (h). the fuel rail is a drilled passage in the cylinder head that routes fuel to each unit injector. the unused fuel is rejected back from the euis (g) into the fuel rail and returned to the back of the fuel filter housing (i). in this portion of the fuel filter housing, the fuel passes by a fuel pressure sen*** (j),&then it travels through a head debris filter (k), which is a 10 micron filter. after flowing through the head debris filter, the fuel enters a chamber that includes the fuel supply pressure quick connect port (l). once the fuel is in this chamber, it will either travel through the low pressure regulating valve (m)/the high pressure regulating valve (n). if fuel goes through the low pressure regulating valve, it will return to the fuel tank. if fuel goes through the high pressure regulating valve, it will pass the fuel temperature sen*** (p), which is mounted into the fuel filter housing. the fuel will return to the fuel filter to be cleaned,&it will be recirculated through this system. ctm188 (20mar01) 03-130-9

controlling the electronic unit injectors (euis) so that fuel is delivered according to a given set of engine conditions, in precise amounts,&at a precise time in relation to piston position. in order to achieve this, the control system performs the following functions: ? constantly monitor engine operating conditions ? precisely determines piston position ? deliver optimum amount of fuel for a given set of operating conditions ? deliver fuel at optimum piston position ? provide multiple control modes ? perform self-diagnosis ctm188 (20mar01) 03-140-3 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=121 electrical control system operation 03 140 4 rg,rg34710,1530 –19–30sep97–1/1 electronic control system operation engine starting mode when the key is turned to the “on” position, a switched power voltage is sent to the ecu allowing the ecu to energize. this allows the ecu to “boot-up” and ready itself for engine start. note: if a wiring problem prevents the key on signal from getting to the ecu, the engine will not start. as soon as the ecu determines using the crankshaft position sen*** input that the engine is cranking, it will determine using the camshaft position sen*** input when cylinder number 1 is coming to top-dead-center at the end of the compression stroke. it will then start injecting fuel when the next cylinder in the firing order (cylinder number 5) is at the correct position before top-dead-center at the end of compression. to provide cold temperature enrichment, the amount of fuel injected is based on the temperature measured by the engine coolant temperature (ect) sen***. at this point, the engine will start&the ecu will go into the running mode. engine running mode in the running mode, the ecu monitors information from the various sen***s, then determines the optimum amount of fuel to inject&the optimum injection timing in order to allow the engine to develop high power while maintaining low exhaust emission output. the camshaft&crankshaft position sen***s allow the ecu to precisely determine piston position in relation to top-dead-center so that the ecu can command the correct electronic unit injector (eui) solenoid at the correct time. the ecu controls fuel delivery by energizing&de-energizing the individual solenoids that open&close the eui spill valves. when the ecu energizes the eui solenoid, the spill valve closes&injection begins. when the correct amount of fuel has been injected, the ecu de-energizes the solenoid, causing the spill valve to open,&fuel injection to stop. rg,rg34710,1531 –19–30sep97–1/1 monitoring engine parameters in order for the electronic control system to deliver fuel according to a given set of operating conditions, the following parameters are monitored by the ecu: ? engine coolant temperature (ect) ? manifold air temperature (mat) ? fuel temperature ? loss of coolant temperature switch ? fuel pressure ? oil pressure ? air vacuum switch ? throttle position ? engine speed ? water in fuel sen*** (wif) ctm188 (20mar01) 03-140-4 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=122 electrical control system operation 03 140 5 rg,rg34710,1532 –19–30sep97–1/4 measuring temperature the engine coolant temperature (ect) sen***, the manifold air temperature (mat) sen***,&the fuel temperature sen*** are all temperature sensitive variable resistors. the sen***s’ resistance goes down as the temperature that it is exposed to goes up (negative temperature coefficient). the engine control unit (ecu) sends 5 volts to the sen***, monitors the voltage drop across the sen***,&compares the voltage drop to preprogrammed values in the ecu’s memory in order to determine temperature. in addition to temperature sen***s, some applications use temperature switches. the loss of coolant temperature switch is an example. temperature switches close when a specific temperature is reached. rg,rg34710,1532 –19–30sep97–2/4 rg10625 –un–30nov99 ect sen*** a—ect sen*** ect

monitors each crank timing notch until the time to start injection occurs, at which time it energizes the electronic unit injector (eui) solenoid to start fuel delivery. it continues to monitor each crank timing notch until the time to end injection occurs, at which time it will deenergize the eui solenoid to stop fuel delivery. in the event of a crank/cam position sen*** failure, a “limp-home” mode will allow the ecu to operate with only one position sen*** input. if the crank position sen*** fails, engine power will be low. if the cam position sen*** fails, long cranking times will be required to start the engine. if both sen***s fail, the engine will die&won’t restart. ctm188 (20mar01) 03-140-12 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=130 electrical control system

unit (ecu) rg10417 –19–20dec00 deere level 6 ecu the engine control unit (ecu) is the “brains” of the electronic control system. the ecu is a self-contained unit containing electronic circuitry and computer software which together perform the following functions: ctm188 (20mar01) 03-140-14 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=132 continued on next page electrical control

based on information from various sen***s ? limit maximum fuel for operation on multiple power curves ? control fuel delivery ? provide min-max/all-speed governing ? perform self diagnosis on the control system ? store trouble codes in memory the ecu connects to the wiring harness through a white, 48-way ecu connector, which is composed of a 30 terminal ecu connector&an 18 terminal ecu connector,&a black, 60-way ecu connector, which is composed of two 30 terminal connectors. the connectors are marked by letters&numbers to help identify the terminals. the ecu is composed of the following subsystems: analog/digital converters this portion of the ecu converts the analog voltage signals from the various sen***s into digital signals that the central processing unit can “understand”. central processing unit (cpu) the central processing unit performs the mathematical computations&logical functions that are necessary in controlling injection fuel quantity&injection timing. the cpu commands the electronic unit injectors (euis)&controls the self diagnostic system. memory the ecu contains 3 different types of memory: — random access memory - ram the ram is like the working desk top of the ecu. data from the various sen***s&the results of various calculations are temporarily stored in ram. information in ram is lost when battery voltage to the ecu is removed. — read only memory - rom the rom contains programmed information. information in rom can only be read, not changed. rom information is retained when battery voltage is removed. — electrical erasable programmable read only memory - eeprom the eeprom contains information programmed in at the factory including engine specific data, and application data. information in the eeprom is retained when battery voltage is removed. ctm188 (20mar01) 03-140-15 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=133 electrical control system operation 03 140 16 dpsg,rg40854,457 –19–14oct99–1/1 cruise control operation the ecu is available with&without the cruise control function. it is an off-road cruise control that maintains constant engine speed under varying load conditions. this function is especially intended for field applications where an operator faces the need to turn the vehicle around at the end of each row. this cruise control allows the driver to use the throttle and/or brake to turn the vehicle around. when ready to resume field operations, the operator brings the engine speed above 1300 rpm&activates the cancel/resume function again to resume cruise speed. an internal timer gives the operator one minute to complete the turnaround maneuver. the cruise control has the normal functions of: ? cruise control power “on”/“off” ? “set”/“bump up” engine speed ? “resume”/“bump down” engine speed ? vehicle brake/clutch pedal to disengage cruise control on 12 volt ecus, the engine speed can be set from two different locations. the primary location would normally be in the cab of the vehicle&is used to set a constant engine speed while the vehicle is being driven. the secondary cruise control is normally used in a location that provides pto speed control&is used with the engine in “neutral”/out of gear. both locations have the normal cruise control functions. ctm188 (20mar01) 03-140-16 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=134 electrical control system operation 03 140 17 dpsg,rg40854,458 –19–14oct99–1/1 engine protection there are two levels of engine protection: ? warning — the warning lamp (if equipped) turns on. causes: – lower than normal oil pressure – engine coolant temperature higher than normal – higher than normal manifold air temperature – lower than normal fuel supply pressure – higher than normal fuel supply pressure – water in fuel detected – high air filter restriction – power derates ? shutdown — the shutdown lamp (if equipped) turns on. causes: – extremely low oil pressure – extremely high engine coolant temperature – loss of coolant – extremely low fuel supply pressure – water in fuel continuously detected there are three different engine protection programs available: ? no protection — the operator must reduce the speed of the engine when the “warning”trouble light is on,&shutdown the engine when a “shutdown” trouble light is on. if a “shutdown” trouble light occurs, it is the responsibility of the operator to shut down the engine. ? engine protection without shutdown — the engine will derate either due to a “warning”/a “shutdown” trouble light. if a “shutdown” trouble light occurs, it is the responsibility of the operator to shutdown the engine. ? engine protection with shutdown — the engine will derate either due to a “warning”/a “shutdown” trouble light. if a “shutdown” trouble light is detected, the ecu will shut down the engine in 30 seconds. if the problem is corrected within the 30 second delay period, the power will increase at a particular rate until full power is reached. the “warning” fault lamp will remain on until the power returns to normal, and at that time, it will shut off. shutdown override note: holding the shutdown override switch continuously “on” will not reset the 30 second timer. the engine protection shutdowns can be overridden for 30 seconds at a time. this can be used to move a vehicle to a safe location. each time the switch is pushed, the shutdown timer is reset to 30 seconds, and the engine will run in a derated power mode. ctm188 (20mar01) 03-140-17 powertech 10.5 l & 12.5 l level 6 fuel system 032001 pn=135 electrical control

applications may have similar derate programs. refer to specific machine manual for application derate programs. low oil pressure protection ? warning: a power derate of 2% per minute with a maximum derate of 20% of rated power will start if the “warning” fault lamp is set. if oil pressure increases over the “warning” fault pressure, the power will increase at the rate of 2% per minute until full power is reached. ? shutdown: a power derate of 20% per minute with a maximum derate of 40% of rated power occurs if oil pressure becomes lower than the “shutdown” fault pressure. if this fault stays on for 30 seconds, the engine will shut down. if oil pressure begins to increase above the “shutdown” fault pressure, the “warning” fault will activate. the power derate will revert to the “warning” fault. note: shutdown only occurs on engines that have the option in their ecu. high ect (engine coolant temperature) protection ? warning: a power derate of 2% per minute with a maximum derate of 20% of rated power will start if the “warning” fault lamp is set. if ect decreases below the “warning” fault pressure, the power will increase at the rate of 2% per minute until full power is reached. ? shutdown: a power derate of 20% per minute with a maximum derate of 40% of rated power occurs if ect exceeds the “shutdown” fault temperature. if ect does not decrease below the “shutdown” fault temperature within 30 seconds, the engine will shut down. if ect decreases below the “shutdown” fault temperature within 30 seconds, the power derate will divert to the “warning” curve. note: shutdown only occurs on engines that have the option in their ecu. loss of coolant protection ? shutdown: a power derate of 20% per minute with a maximum derate of 40% of rated power occurs if the coolant level becomes low. if the loss of coolant switch does not reset within 30 seconds, the engine will shutdown. if the switch resets within 30 seconds, the power KEY PART NO.
