Product Status Report
The Product Status Report is a feature that is available through Cat® Electronic Technician (ET). The Product Status Report allows a download of all the information that is stored in the ECM. This information includes information about the ECM's active and logged codes, totals, configuration settings, and histograms.In addition to the information listed above, there may be additional information depending on the ECM that is pulling the product status report (engine, transmission, machine, implement, display, and so on).This information can be used to determine how the equipment is set up from the factory. The information can be sent to the Dealer Solutions Network (DSN) for review to aid in diagnosis of issues, and can be used to aid in keeping records on the equipment.The product status report is available in Cat ET under the "Information" tab or on the toolbar at the top of the screen.Electronic Controls
Electronic Control Module
The ECM consists of two main components, the control computer (hardware) and the flash file (software). The control computer consists of a microprocessor and electronic circuitry. The flash file contains the engine's operational characteristics. The operating maps influence the engine's performance.Engine Governor
The engine ECM governs engine speed. The engine ECM and the flash file work together by controlling the amount of fuel that is delivered by the injectors. Desired engine rpm is determined by the throttle position sensor signal and certain sensor readings. Actual engine rpm is monitored by the engine speed/timing sensor.Fuel Injection
The engine ECM controls the timing and the duration of the fuel that is injected. The engine ECM varies the signals to the fuel injectors. Fuel is injected only while an injector solenoid is energized by a 105 V signal from the engine ECM. The timing of the injection signal determines the engine timing. The length of the injection signal determines engine speed.Injection timing depends on the desired engine rpm and load. The ECM detects the top center of each cylinder. The ECM sends an injection signal at the desired time.Cold Mode Operation
Cold mode operation automatically stops fuel injection to cylinders that are not firing. Cold mode operation has the following benefits: increased startability, reduced warmup period, and reduced white smoke. Cold mode is activated whenever the engine coolant temperature falls below a predetermined value.FRC Limit
The flash file inside the engine ECM sets certain limits on the amount of fuel that can be injected. The FRC limit is a limit that is based on the boost pressure. The boost pressure is calculated as the difference in pressure between atmospheric pressure and turbocharger outlet pressure. The FRC limit is used to control the air/fuel ratio for control of emissions. When the engine ECM senses a higher boost pressure, the engine ECM increases the FRC limit. A higher boost pressure indicates that there is more air in the cylinder. When the engine ECM increases the FRC limit, the engine ECM allows more fuel into the cylinder.Rated Fuel Position
The rated fuel position is a limit that is based on the power rating of the engine. The rated fuel position is similar to the rack stops and the torque spring on a mechanically governed engine. The rated fuel position determines maximum power and torque values for a specific engine family and a specific rating. The rated fuel position is programmed into the flash file at the factory.
