Electronic Control Module (Engine)
The engine ECM controls the engine speed on a 3500B EPG engine. The engine speed is based on the operator input from the speed potentiometer (SP). The engine speed is also based on the feedback from the sensors for the engine ECM .
The GSC receives the following information from the engine ECM:
- engine oil pressure
- engine coolant temperature
- engine hours
- system battery voltage
The above information is shown on the lower display of the GSC. The engine ECM is used by the GSC in order to monitor system faults such as low engine oil pressure or high engine coolant temperature.
The GSC receives the diagnostic codes from the engine ECM. The GSC displays the diagnostic codes as a convenience to the operator. The GSC does not interpret the codes and the GSC does not react to the codes. For more information on the management of diagnostic codes by the GSC and the engine ECM, see Testing And Adjusting, "Fault Identification".
