(14) Cat ET This engine is designed for electronic control of most engine operating functions. The Engine Management System (EMS) provides this control. The EMS is made up of a network of electronic controllers. These controllers communicate through the data link network to share information that is related to the operation of the engine. The EMS also provides information to external devices, such as the operator display panel. The electronic system consists of the control modules that make up the EMS, the wiring harness, switches, sensors, and fuel injectors. The control modules receive information from the sensors and the switches on the engine. The information is shared over the data link. This information is then processed in order to provide engine control. Refer to Troubleshooting, "Data Link Features" for an overview of the data links for this engine.Primary and Secondary Electronic Control Module (ECM)

Engine ECM
The engine 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 operational characteristics. The operating maps that influence the engine performance are also contained in the flash file.The engine ECM provides engine control by altering the signal that is sent to the fuel injector solenoids. By controlling the signal timing and duration, the engine
