Electronic Control Analyzer & Programmer (ECAP)An electronic service tool developed by Caterpillar. This tool is used for programming and diagnosing a variety of Caterpillar electronic controls. The 3126B Marine Engine will not support ECAP.Electronic Control Module (ECM)The ECM is a control computer for the engine that provides power to the engine electronics. The ECM receives inputs from sensors and other components that monitor the operation of the engine. The ECM accepts inputs that monitor and outputs that control or change to act as a governor to control the engine speed.Electronic Engine ControlThe complete electronic system that monitors and controls the operation of the engine under all conditions.Electronic Technician (CAT ET)CAT ET is a software program that functions as a service tool used on a personal computer (PC).Estimated Dynamic TimingThe ECM estimation of actual injection timing.Event Code (EID)An event code indicates an abnormal operating condition of the engine. An event code does not necessarily indicate a problem that is within the electronic system.Failure Mode Identifier (FMI)The FMI is a number that corresponds to the type of failure that the component experienced. The FMI is adopted from SAE J1587 standard practice diagnostics.Flash CodeFlash codes are Caterpillar proprietary code numbers that are indicated by the flashing of the diagnostic lamp.Flash ProgrammingFlash programming is a method of programming an ECM with an Electronic Service Tool. The data link is used for transmitting the program instead of replacing components that have different software.Fuel Ratio Control (FRC)The FRC fuel position is a limit that is based on control of the fuel to air ratio. This control improves the control of emissions. When the ECM senses a higher boost pressure, the FRC increases the "FRC Fuel Pos" limit. A higher boost pressure allows more air in the cylinder. An increased "FRC Fuel Pos" allows more fuel into cylinder.Fuel PositionThe fuel position is an internal signal within the ECM that goes from the Electronic Governor to the Fuel Injection Control. The fuel position is determined by the Desired Engine Speed, the FRC Fuel Position, the rated fuel position and the engine speed.Full Load Setting (FLS)The FLS is number that represents the adjustment of the fuel system that is made at the factory to set the maximum fuel delivery of the fuel system. The correct value for this parameter is stamped on the engine information ratings plate. This parameter must be programmed. Otherwise, a Diagnostic Code 253-02 Check Customer Or System Parameters and a flash code 56 will be generated.Full Torque Setting (FTS)The FTS is similar to the Full Load Setting. The FTS must be programmed. Otherwise, a Diagnostic Code 253-02 Check Customer Or System Parameters and flash code 56 will be generated.HarnessThe harness is a wiring bundle that connects all components of the ECM.Hertz (Hz)Hertz is a measure of frequency in cycles per second.HistogramA bar graph indicating the relative frequency of engine operation in specific operating ranges.Hydraulic Electronically Controlled Unit Injector (HEUI)A HEUI is an fuel injector pump which is hydraulically actuated. The HEUI is a electronically controlled unit injector that combines the pumping, the electronic fuel metering and the fuel injecting elements in a single unit.Inlet Air Manifold Pressure SensorThis sensor measures the absolute air pressure at the inlet air manifold. The difference between the pressure at the inlet air manifold and the atmospheric pressure is the boost pressure.Integrated Electronic ControlsThe engine is designed to operate with electronic controls to control the operation of the engine. The engine will not operate without the electronic controls.Logged Diagnostic CodesLogged diagnostic codes are stored in the ECM memory. The codes are indicators of possible causes of intermittent problems. Refer to Diagnostic Code.Oil Pressure SensorThis sensor sends a signal to the ECM that indicates the engine oil pressure. The oil pressure sensor is part of the Caterpillar Engine Monitoring.Open CircuitAn open circuit exists when an electrical wire or connection is broken or a switch is open. An open circuit prevents a signal or electrical current from reaching the intended destinationOriginal Equipment Manufacturer (OEM)An OEM is the manufacturer or customer of a machine or vessel in which a Caterpillar engine is installed.ParameterA parameter is a value that can be programmed in the ECM. This value determines the characteristics of operation or the behavior of an engine that is installed in a machine or vessel.PasswordA password is group of numeric or alphanumeric characters that must be entered before parameters can be changed. Customer passwords are set by the customer. Factory passwords are set by Caterpillar. Some engine specifications require factory passwords before the setting can be changed. Passwords are also required to clear certain diagnostic codes.Personality Module or Ratings Personality ModuleThe module that contains all of the software instructions for the ECM and the performance maps for a specific family of engines. This module is located inside of the ECM.Pulse Width Modulation (PWM)PWM is a signal that consists of variable width pulses at fixed intervals. The pulse width is a ratio of "Time On" versus total "Time Off". Refer to Duty Cycle.Rated Fuel PositionThis position indicates the maximum allowable fuel position. This fuel position is the longest injection pulse which produces the rated power of the engine. The rated fuel position is called "Rated Fuel Pos" on an Electronic Service Tool.Reference VoltageThe reference voltage is a constant and regulated voltage supplied by the ECM to a sensor. The reference voltage is used by the sensor to generate a signal voltage.SensorA sensor is a device used to detect and convert a change in pressure, temperature, or mechanical movement into an electrical signal.Short CircuitA short circuit occurs when an electrical circuit is unintentionally connected to an undesirable point. A wire that rubs against a metallic object until the insulation is worn so that the wire makes contact against the grounded object is an example of a short circuit.SignalA voltage or waveform that is gener
