The system includes the following components: various inputs (switches and sensors), an electronic control module, various outputs (solenoid valves) and a monitoring system. The Engine Electronic Control Module (ECM) controls the engine and pumps. The Machine ECM also controls the following functions:
Engine Speed
Attachment Actuators
Pump power shift pressure
Hydraulic
