The electronic control system includes engine monitoring. The system monitors engine oil pressure, coolant temperature and coolant level. All truck engines are shipped from the factory with the following sensors: engine oil pressure sensor and coolant temperature sensor. The Original Equipment Manufacturer (OEM) is responsible for providing and installing the coolant level sensor. The coolant level sensor is the only sensor that can be individually selected for engine monitoring. The software for the Engine Control Module (ECM) contains a customer programmable parameter that enables the coolant level sensor. The default factory setting is "NO". The ECM customer programmable parameters have four levels that are for engine monitoring:
Warning (factory default)
Engine derate
Engine shutdownWarning Mode
Warning mode uses the following sensors: engine oil pressure, coolant temperature and optional coolant level sensor. When a diagnostic code is active, the check engine lamp will flash and the warning lamp will come on.Engine Derate and Engine Shutdown
The engine derate and the engine shutdown allows the ECM to alter engine performance in order to avoid damage to the engine. The engine should return to normal conditions once the problem is corrected. When the engine is derated, the check engine lamp and the warning lamp will flash. For the operating conditions that cause these modes, refer to the appropriate section for the sensor.Electronic Control System Operation
The fuel delivery and injection timing are electronically controlled. In comparison to engines that are controlled mechanically, the electronic control system provides increased control of timing and increased control to the fuel to the air ratio. Injection timing is achieved by precise control of injector firing time, and engine power is controlled by adjusting the firing duration. The ECM energizes the fuel injection solenoid in order to start the injection of fuel. The ECM will de-energize the fuel injection solenoid in order to stop the injection of fuel. Refer to the Systems Operation, "Fuel System" for a complete explanation of the fuel injection process.The engine uses the following types of electronic components: input, control and output.An input component is one that sends an electrical signal to the ECM. The signal that is sent varies in either voltage or in frequency when there is a change in some specific system of the vehicle. An example would be the engine speed/timing sensors or the coolant temperature sensor. The ECM sees the input sensor signal as information about the condition, environment, or operation of the
