REPAIR KIT 1471953 - Caterpillar

ECM. The following criteria are used in order to determine the desired engine speed (rpm): the Throttle Position Sensor, the Speed-timing Sensor and the Customer Parameters.Desired Timing Advance (DES Timing ADV on ECAP) - The fuel injection timing advance is calculated by the ECM. The calculation is used to meet emission and performance specifications.Diagnostic Code - A diagnostic code is an indication of a problem or event in the electronic system.Diagnostic Event Code - These codes indicate an event. The codes are not necessarily an indication of a problem within the electronic system.Diagnostic Fault Code - These codes indicate an electronic system malfunction which will indicate a problem with the electronic system.Diagnostic Flash Code - This code indicates a malfunction of the electronic system. This code can also indicate an event that is detected by the electronic system. The code is Check Engine/Diagnostic Lamp.Diagnostic Lamp - This is used to warn the operator of the presence of an active diagnostic code. This term is also referred to as the Check Engine Lamp.Direct Current (DC) - Direct current is the type of current that flows consistently in only one direction.Duty Cycle - See Pulse Width Modulation.Electronic Control Module (ECM) - The ECM is the engine's control computer. The ECM provides power to the electronics for the system. The ECM monitors the information that is input by the system. The ECM acts as a governor in order to control engine rpm.Electronic Control Module (ECM) Fan Control - The ECM may control the cooling fan through a relay that is installed by the OEM. The ECM controls the relay that is based on coolant temperature, inlet manifold air temperature, and boost pressure. The relay can also be controlled by the ECM when the following switches are installed by the OEM:air conditioning high pressure switch, PTO ON/OFF, manual fan override switch and retarder solenoidElectronic Engine Control - The electronic engine 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.Electronic Unit Injector (EUI) - The injection pump is a mechanically actuated, electronically controlled unit injector. The EUI combines the pumping, electronic fuel metering, and injecting elements into a single unit.Engine Speed-Timing Sensor - This sensor provides a Pulse Width Modulated signal to the ECM. The ECM interprets this signal as the crankshaft position and the engine speed.Electronic Technician (ET) - Electronic Technician is a Caterpillar electronic service tool. ET is used for diagnostics and for programming a variety of electronic controls.Estimated Dynamic Timing - This is the estimated calculation of actual injection timing by the ECM.Failure Mode Identifier (FMI) - This identifies the type of failure that was experienced by the component. This was adopted from SAE Standards"Section J1587" diagnostics.Flash Code (FC) - A flash code is a Caterpillar proprietary code number which is flashed on the diagnostic lamp.Fuel Ratio Control (FRC) - The FRC is a limit that is based on
