Information:

Engine Start Interlock
The Hydrostatic Transmission electronic control module controls the start relay in order to provide the function for the engine start interlock. The ECM will energize the start relay when the key switch is in the start position and the parking brake switch is in the set position. Transmission Neutral Interlock
Note: Whenever a level III warning is generated, the function for the transmission neutral interlock is active. When the failure is resolved, a neutral reset is required before resuming normal machine operation.The transmission neutral interlock is active after the power is supplied to the machine. The transmission neutral interlock is active when the engine is started. The transmission neutral interlock is active when the parking brake switch is activated.The following conditions must be true in order to engage the transmission and following conditions must be true in order to release the parking brake.
The level 3 fault has been corrected.
The engine is running.
The parking brake switch is released.Note: All three conditions must occur in order to perform the neutral reset function of the joystick. Engine Start Aid
The engine start aid provides enhanced starting capability during cold weather. The machine ECM controls the air inlet heater and the start aid valve as a function of the engine temperature, the key start switch and the engine running signal.The engine temperature is determined by two coolant temperature sensors. One is directly connected to the temperature gauge in the cab. The other coolant temperature sensor is mounted on the radiator top tank and is connected to the machine ECM and will be used to determine if the inlet air heater should be cycled. The inlet air heater relay is an on/off switch that controls the engine's inlet air heater. When the relay is not energized (0 volts), the heater is not running. When the relay is energized (12 volts), the heater is running.The start aid valve is an attachment that enhances the starting capability of the engine by adding ether to the fuel mixture during start up. The start aid valve relay is an on/off switch that controls the start aid valve. When the relay is not energized (0 volts), start aid is not provided. When the relay is energized (12 volts), then ether is supplied to the engine. Engine Shutdown
The machine ECM controls the engine fuel shutoff solenoid and fuel lift pump relay based on the status of the machine key start switch and the engine operating status. The engine will shut down when the key switch is turned to the OFF position. Engine Fuel Shutoff Solenoid
The on/off fuel shutoff solenoid controls the engine fuel pump. When the solenoid is not energized (0 volts), the fuel pump and engine do not operate. When the solenoid is energized (12 volts), the fuel pump and engine operates. When the key switch is turned on, the fuel shutoff output will energize the fuel shutoff solenoid. When the key switch is in the OFF position, the output will not energize the fuel shutoff solenoid.Fuel Lift
