The 315C has one travel pressure switch. The 318C and 321C have two travel pressure switches.Note: The Engine Control Module is on the 325C and on the 330C.The controller is connected to the machine through two 54-pin connectors. The controller monitors the system through the inputs. Then, the controller adjustments the system through the outputs. The controller will control the hydraulic output of the pump by adjusting the power shift pressure according to the load on the machine.
