Fast IdleFast Idle RPM determines the preset Fast Idle engine rpm as controlled using the Fast Idle Enable Switch. Fast Idle operates similar to cruise control, except it governs engine rpm with the vehicle stationary, or at low vehicle speeds.Flash Code (FC)The Caterpillar proprietary code numbers which are flashed out on the diagnostic lamp. Flash ProgrammingA way of programming or updating an ECM with an Electronic Service Tool over the data link instead of replacing components.Fuel Ratio Control (FRC)FRC Fuel Pos. - is a limit based on control of the fuel-air ratio and is used for emissions control purposes. When the ECM senses a higher boost pressure (more air into cylinder), it increases the "FRC Fuel Pos" limit (allows more fuel into cylinder).Fuel PositionAn internal signal within the ECM, from the Electronic Governor to Fuel Injection Control. It is based on Desired RPM, FRC Fuel Position, rated fuel position and engine rpm. Reference "3100 System Overview" in Section 1 of this manual.Full Load Setting (FLS)Number representing fuel system adjustment made at the factory to "fine tune" the fuel system maximum fuel delivery. Correct value for this parameter is stamped on the engine information ratings plate. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Full Torque Setting (FTS)Similar to Full Load Setting. This parameter must be programmed or a Diagnostic Code 253-02 Check Customer Or System Parameters (56) will be generated.Gear Down ProtectionProgrammable High Gear Limits used to promote driving in higher gears for increased fuel economy.HarnessThe wiring bundle (loom) connecting all components of the Electronic System.Hertz (Hz)Measure of frequency in cycles per second.Hydraulic Electronic Unit Injector (HEUI)The injection pumping is hydraulically actuated, electronically controlled injector combining the pumping, fuel metering and injecting elements in a single unit.Idle RPM LimitProgrammable parameter which indicates the maximum allowable engine rpm when an engine rpm is set using the Cruise Control On/Off switch and SET/RESUME switch.Idle Shutdown TimeProgrammable parameter which indicates time (in minutes) that the engine will idle before shutting down.Idle/PTO Bump RPMProgrammable parameter indicating the amount which the engine RPM will be incremented/decremented when the Accel/Decel switches are briefly toggled.Injection Actuation Pressure Control ValveThis is an electronically controlled dump valve maintaining the high pressure for the high pressure oil manifold. The valve outputs controlled pressure depending on inputs from the ECM. The control valve regulates the high pressure oil to the injectors through the high pressure rail to provide the actuation force to determine the injection pressure for the engine.Injection Actuation Pressure SensorA device used to detect and convert mechanical oil pressure in the high pressure manifold to an electrical signal to the ECM.Inlet Air HeaterThe Inlet Air Heater is used to improve the cold start capability of the engine and to reduce white smoke. The operation is determined at three different times, Power Up/Preheat, Cranking and Engine Started Cycle, based on engine parameters.Intake Manifold Air Temperature SensorThis sensor detects the intake manifold air temperature. The ECM monitors the inlet
