ENGINE AR-COMPLETE 3193582 - Caterpillar

Check Engine Lamp - The dash check engine lamp is sometimes called the diagnostic lamp. The dash check engine lamp is used to warn the operator of the presence of an active diagnostic code.Desired RPM - The desired rpm is input to the electronic governor within the ECM. The electronic governor uses the signal from the Accelerator Pedal Position Sensor, the Engine Speed Sensor, the Cruise Control, and the Customer Parameters in order to determine desired rpm.Diagnostic Code - A diagnostic code is sometimes called a fault code. A diagnostic code is an indication of a problem or event in the electrical engine systems.Diagnostic Event Code - These codes indicate an event. Diagnostic event codes are not necessarily an indication of problem within the electronic system.Diagnostic Fault Code - Diagnostic fault codes indicate an electronic system malfunction that indicates a problem with the electronic system.Diagnostic Flash Code - Diagnostic flash codes are used to indicate a malfunction within the electronic system. Diagnostic flash codes are also used to indicate an event that is detected by the electronic system. The codes are flashed on the dash check engine lamp.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.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 Analyzer Programmer (ECAP) - The ECAP is a Caterpillar electronic service tool. The ECAP is used for programming and for diagnosing various types of electronic controls.Electronic Control Module (ECM) - The ECM is the engine's control computer. The ECM provides power to the electronics. The ECM monitors data that is input from the engine's sensors. The ECM acts as a governor in order to control engine rpm.Electronic Unit Injector - The fuel injection pump and the fuel injector nozzle assembled. The amount of fuel that is injected is controlled by the electronics. The pumping action is controlled mechanically.ECM Fan Control - The ECM controls the cooling fan relay. The ECM uses the following information to control the cooling fan relay: coolant temperature and the high pressure switch on the air conditioner.Electronic 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 Technician (ET) - The ET is a Caterpillar electronic service tool that is used for diagnosing and programming a variety of electronic controls.Engine Speed/Timing Sensor - The engine speed/timing sensor provides a pulse width modulated signal to the ECM. The ECM interprets the signal as the crankshaft position and the engine speed.Failure Mode Identifier (FMI) - The FMI describes the type of failure that was experienced by the component. The codes for the FMI were adopted from the standard practices of SAE (J1587 diagnostics).Flash Code - TheCaterpillar code numbers that are
